Partner 350 chainsaw repair manual. Partner 350 chainsaw: malfunctions and their elimination

One of the main features of this saw its users note the durability of operation with a minimum number of failures. And yet they occur. To determine why the saw stopped working, you need to make an elementary diagnosis.

If the saw does not start, then:

  • there is no spark on the candle;
  • no fuel is supplied;
  • no air enters.

First, you should check for the presence of a spark: unscrew the spark plug, attach it to the high-voltage wire and put it on the cylinder, pull the starter. If there is a spark, then clean and adjust the clearance on the candle (0.5. 0.65 mm). If it is not, then you need to change: either the flywheel or the coil (magneto). In addition, the candle itself may fail or the high-voltage wire may interrupt.

The next step is to check the fuel supply. To do this, disconnect the feed hose from the carburetor and check its presence. An absence may indicate a clogged fuel filter or feed system. And the carburetor itself may become clogged.

If you do not have experience in repairing and cleaning it, entrust this work to specialists.

If the air supply worsens, the saw should start, but it will work poorly. Remove and rinse the air filter. Replace it only after it has completely dried.

If the saw starts up well, runs at idle and stalls when gas is supplied, the muffler is most likely clogged. Remove, disassemble, wash, put in place and work on.

With your own hands, you can also change the saw bar and chain, carburetor, starter, oil pump, ignition and clutch.

And you will be able to replace the broken starter cable after watching this video:

We recommend instructing specialists to perform more complex chainsaw repairs related to replacing a cylinder-piston group or crankshaft, although if you are familiar with two-stroke engines, this work will not be difficult for you, and Partner chainsaw parts are not in short supply in Russia.

Partner 350 chainsaw Starts up and Stalls. Related posts

Why does the chainsaw stall when I press the gas?

Hello! If you are on this page, then, most likely, your chainsaw stalls when you press the gas, and you are eager to find out what is happening and what to do about it. Still, I’ll try to help you in this dilemma by examining the more widespread prerequisites for such a collapse, as well as ways to eliminate them.

To begin with, I’ll write for novice users that many chainsaws asks for warming up the engine at idle for about one minute before work. Why the chainsaw starts and stalls. the reasons and. Here the chainsaw has stalled and will not start, or the Stihl chainsaw stalls. Until the engine warms up, the saw may stall when gas is added.

So, if a heated chainsaw can idle, but stalls when loaded, then this means that:

  • incorrectly configured or clogged carburetor. the most common case;
  • it lacks air, the consumption of which increases sharply with increasing speed. this means that the air filter is dirty (a rare case, because the filter is dirty evenly, because the user first notices the loss of power);
  • she lacks fuel, the consumption of which also increases with increasing speed. this means that the fuel filter is dirty (also an infrequent case);
  • well, the worst case, if there is excessive friction between the piston and the cylinder wall due to a lack of oil in the fuel consistency. after this operation of the chainsaw, you will most likely fly into repair of the piston group, because on the piston and cylinder walls there will be bumps that prevent the work of the saw.

We will analyze these cases separately.

Partner 350 chainsaw will not start. How is the mechanism

Virtually all tools, both foreign (Husqvarna, Makita, Stihl, Partner 350), and Chinese chainsaws, and Russian (Friendship, Urals), are arranged identically. The partner 350 chainsaw will not start. Therefore, finding the reason why the device does not start and stalls is not difficult.

There are four elements in which difficulties may arise:

  • The fuel for which the carburetor is responsible;
  • Grease;
  • Air that flows;
  • A spark whose quality depends on the ignition unit.

All of them depend on each other and interact with each other. If any element does not work correctly, then the saw stops working.

To begin with, all instruments start up differently. hot and cold. Two commonly used mechanisms are responsible for this process.

Be sure to see what is written in the user manual. It says that when you turn on you need to make sure that the emergency stop brake is fixed. But to start a saw with a brake is much more difficult, so sometimes it is better not to turn on the brake.

As you can learn from the instructions, inside the case there is a fuel tank and engine, and outside. the saw part (tire with chain), handle and starter.

First you need to figure out exactly how the tool does not start. For example, the saw starts up, but immediately stalls, or loses its power, the quality of the cut.

Perhaps outages occur due to problems in the engine. Stihl (stihl) chainsaw won’t start: how to start. But I would not recommend disassembling it right away. A chainsaw does not start: causes and methods. Do you have a chainsaw? That chainsaw does not start. (Husqvarna). It is better to look for a problem from the simplest option.

Model range Interskol chainsaws

Now, let’s take a closer look at the most popular Interskol chain saw models, which today can be found on sale, but first we’ll understand the designation of the models. PTsB-14 / 45L. means a gasoline chain saw with a 14-inch tire. Engine displacement is 45 cubic centimeters. Now in more detail.

PTsB-14 / 45L

The chainsaw is designed for non-professional and semi-professional use. Recommended by the manufacturer for work on construction sites, sawmills, for harvesting firewood in the private sector. It can be used by gardeners as a tool for trimming shoots or dry branches.

  1. Headset length 35 cm.
  2. The number of chain links is 59.
  3. Engine displacement is 45 cm3.
  4. The weight of a fully equipped and refueled saw is 6.9 kg.
  5. Power at maximum speeds 2.4 hp

Idling speed 2600-2700 rpm. Recommended maximum revolutions of not more than 9500. The saw is fully consistent with state standards:

  • GOST 31742-2012;
  • GOST 16519-2006;
  • GOST 12.2.030-2000.

What is noteworthy, the manufacturer in the instructions for the chainsaw indicates the designated service life, which is 3 years from the date of sale of the tool, but makes a reservation that this value is for those chainsaws that are used as professional. It turns out that the manufacturer admits that his chainsaw can be used as a professional tool and tested it in this mode.

The following models of Interskol chainsaws are PTsB-16 / 45L and PTsB-18 / 45L. They are made on the basis of PCB-14 / 45L. They differ only in the length of the tire and, accordingly, in the number of chain links that are supplied as standard.

The following is an overview of a chain saw with a 18 / 45L gasoline engine. The video shows the equipment, describes the purpose of this model. The operator also gives advice on where it is better to use a chainsaw and what rules should be observed in order not to harm the engine.

PTsB-18 / 52L

The model is a bit more powerful, which means it is easier to cope with tasks of increased complexity, for example, with the cutting of thick frozen wood.

  1. Engine displacement is 52 cm3.
  2. The tire is 18 inches long.
  3. The number of chain links is 72.
  4. Weight 7.2 kg.
  5. Maximum power 2.4 kW or 3.3 hp

The saw is a bit heavier than the previous model, but this is offset by increased productivity. On the basis of this model, another Interskol chainsaw, PCB-20 / 52L, was made. As in the case of models with a volume of 45 cm3, the PTsB-18 / 52L and PTsB-20 / 52L differ only in the length of the tire and the number of chain links.

It turns out that under the Interskol brand only two chainsaw models are sold, one with a volume of 45 cm, the other 52. All other models are just copies on which saw sets are different in length.

Interskol chainsaws significantly lose to competitors in terms of assortment. For example, the Carver line of chainsaws, which are considered one of Interskol’s direct competitors, has more than five saw models of various sizes and power

Saws Interskol, despite the fact that they are made quite high quality, belong to the low price category. Today on the official website of the company prices for Interskol saws are as follows:

  1. PTsB-14 / 45L. 4490 rubles.
  2. PTsB-16 / 45L. 4760 rubles.
  3. PTsB-18 / 45L. 4940 rubles.
  4. PTsB-18 / 52L. 5120 rubles.
  5. PTsB-20 / 52L. 5390 rubles.

For comparison, a Stihl MC 180 chainsaw with an engine power of 1.5 kW and a 35 cm long tire, which is a leader in the domestic segment, costs about 12,000 rubles.

User reviews

Two years ago, I bought the Interskol chainsaw, for all the time of operation there were no problems with it. Immediately after the purchase, I read the user manual and did everything as it says.

I used proprietary engine oil, I bought a special Oregon to lubricate the chain. A few days ago, he drove a saw to a service center, where she was diagnosed. According to the results of the check, she saw in good condition, and will last a long time.

I recommend Interskol chainsaws to all my friends.

Partner 350 How To Remove A Carburetor

Today, in almost every household there is a chainsaw, which is a worthy replacement for axes and hand saws. The ideal solution for people living in a private house, or engaged in construction, would be the Partner 350 hand-held chainsaw. This tool of the Swedish manufacturer is very convenient and compact, so it is suitable for any work on a personal plot.

However, improper maintenance and intensive use of the unit can lead to its breakdown. In this case, it is not necessary to immediately contact a service workshop. Many malfunctions can be eliminated with your own hands. To do this, it is enough to study the saw device and video instructions for its repair.

Design features of the Partner 350 chainsaw

The reliable and convenient saw in use of this model has a gasoline engine with 1300 W. It differs in easy start-up, which is carried out due to the integrated professional fuel pump and electronic ignition system.

The chainsaw is equipped with a protection system that automatically activates a double inertial chain brake. Chain lubrication also occurs automatically. It is very easy to change the chain tension of this unit with just two keys.

The chainsaw is equipped with a fuel primer, so it is easy to start at any time of the year. The tool starter drum is equipped with a special impeller, with which it is cleaned of contaminants.

Filter with CCS able to trap all residual particles. In addition, this system allows you to use the air filter for a long time, while saving fuel consumption.

Partner 350 chainsaw manufacturers equipped the cylinder walls of the piston group with a chrome coating, which significantly increases the tool life.

The main malfunctions of the Partner 350 chainsaw

Most often, the cause of a tool breakdown is associated with interruptions in the operation of the engine or other components and systems. To resolve any malfunctions, disassembly is required. To do everything right, you need to know the design features of the chainsaw and the main causes of its breakdown.

Checking the ignition system

First of all, if any chainsaw malfunctions, you should inspect the spark plug. To do this, first disconnect the wire, and then with the help of a special key the candle itself is turned out. In her appearance, you can understand the cause of the problem:

  1. Partner 350 How To Remove A Carburetor

    A chainsaw candle covered with soot indicates the use of low-quality oil, the wrong ratio of oil and gasoline when cooking fuel, or a poorly adjusted carburetor. In this case, the candle must be cleaned of soot with a needle or an awl, and the electrodes should be washed and rubbed with sandpaper.

  2. If the spark plug is heavily sprayed with fuel, then most likely the carburetor is incorrectly adjusted or the rules for starting the tool have been violated. To remove excess fuel, shut off the fuel supply, turn on the starter and check the combustion chamber. After that, the candle is rubbed, twisted into place, and the mechanism starts again.
  3. A completely dry candle indicates that the fuel mixture does not enter the cylinder of the chainsaw. In this case, the cause of the breakdown is not in the ignition system, so the candle is put back.

Video: Partner 350 How To Remove A Carburetor


To check the performance of the spark plug, you need to put on the ignition cable, connect the cylinder and the nut of the spark plug with pliers, and start the starter. If there is no spark, then the candle must be replaced.

Chainsaw fuel system repair

Reasons why fuel-air mixture does not enter the cylinder, there may be several:

  • clogged fuel filter;
  • clogged holes in the cap of the fuel tank (breather);
  • insufficient fuel;
  • improperly adjusted carburetor;
  • clogging of the channels or violation of the integrity of the carburetor membrane.

To diagnose a filter or breather clogging, you just need to disconnect the hose and see how the fuel flows. The tank stream should pour out good pressure. If it is intermittent and weak, then the filter must be pulled out through the neck of the tank and rinsed or replaced, and the breather should be cleaned with a needle.

Chainsaw carburetor is a fairly complex device, equipped with many small parts. Therefore, it is better to entrust disassembly and repair to specialists.

If the carburetor filter is simply clogged, then it can be carefully removed, shaken, washed with detergents and put in place.

With your own hands, the carburetor can only be adjusted. This is done with three screws strictly according to the instructions.

Muffler cleaning

In some cases the engine starts to stall and smoke at high speeds. At the same time, it works fine at low speeds. Most likely the reason is that the muffler is clogged with combustion products.

To eliminate this malfunction, the muffler is removed, disassembled and, using detergents, is cleaned of carbon deposits. After that, it must be dried with a hairdryer and put in place.

While the muffler is removed, the outlet of the saw must be covered with a clean rag.

Repair of the cylinder-piston group

In this group, problems are quite rare. If any element breaks, it is most often replaced with a new one.

The main malfunctions of the cylinder-piston group:

  1. Engine power may be lost due to low (about 5 atm) pressure in the cylinder. To measure it, you need a special pressure gauge called a kopressometer. Normal cylinder working pressure is 8-9 atmospheres.
  2. If hot gases are emitted into the crankcase, the piston rings will most likely sink.
  3. Loss of pressure and the release of gases through the slots may indicate the destruction of the gaskets of the cylinder head. They must be replaced.

To fully assess the state of all elements of this group can only be visually through the hole from the removed muffler. If this is possible, then the cylinder head or the entire cylinder is removed.

If the cause of the breakdown of the chainsaw is insignificant, it does not matter. the tool was made by Russian or Chinese manufacturers. Dismantling and repair of the unit can be done quite easily with your own hands, having previously studied its design and video troubleshooting instructions.

Chainsaw carburetor adjustment: we analyze all the technical nuances of work

Suburban construction and repair can not do without the use of chainsaws, as well as garden care. Due to a malfunction of the tool, all the work can get up, so it is so important to be able to disassemble it yourself, find problems and fix them. With enough experience and dexterity, even adjusting the carburetor of the chainsaw is possible. the procedure is complex, or rather, jewelry. How to carry out adjustment procedures, we suggest that you take apart today.

Chainsaw carburetor device

Not a single repair measure is complete without knowledge of the fundamentals of the mechanism. Understanding the components and the principle of operation, it is easier to determine the cause of the breakdown.

Any malfunction in the carburetor threatens to stop the engine

The carburetor is one of the main functional parts of the engine, which serves to prepare and supply the fuel mixture, consisting of certain proportions of fuel and air. As soon as the proportions are violated. the engine begins to "junk", and even completely stops working.

You can achieve the correct operation of the carburetor by examining its "filling":

  • Tube with transverse flap for adjusting air flow.
  • Diffuser. constriction to increase air flow rate, located near the fuel inlet.
  • The atomizer from which the fuel is supplied (fuel needle in the diagram).
  • A float chamber that controls the fuel level at the entrance to the channel.

Here’s what it looks like in the diagram:

The diagram shows the interaction of fuel and air flow.

Principle of operation: a stream of air in a diffuser sprays fuel, creating a mixture entering the cylinder. The greater the amount of incoming fuel, the higher the engine speed. Carburetors of various models work according to the same scheme.

When is adjustment necessary at all?

Specifically, adjusting the carburetor of the chainsaw is required in rare cases, more often there are problems associated with the flow of fuel or the wear of parts. But sometimes “symptoms” indicate that it is necessary to regulate the mechanism. Here are some signs:

Video: How to Connect Hoses Partner 350


  • After the engine starts, it immediately stalls. As an option. it won’t start at all. The reason is an excess of air and a shortage of fuel.
  • Increased fuel consumption, and as a result. a large amount of exhaust gas. This is due to the reverse process. supersaturation of the mixture with fuel.

The reasons for the adjustment failure can be mechanical:

  • Due to strong vibration, the protective cap is damaged, as a result, all three bolts lose their installed fixation.
  • Due to wear on the piston of the engine. In this case, setting up the carburetor of the chainsaw will help out only for a while, it is better to replace the worn part.
  • Due to clogging caused by low-quality fuel, scale or damage to the filter. The carburetor requires complete disassembly, flushing and adjustment.

If the chainsaw suddenly stops working, it is necessary to disassemble it to find out the reasons.

Step-by-step disassembly instructions

The carburetor device of models of different brands is almost the same, so let’s take the Partner chainsaw as an example. Each element is carefully removed and stacked in order, so that later it is easier to assemble.

Next, remove the tip of the cable.

The arrow shows the tip of the cable to be removed.

To the left of the fitting we tighten the gas hose.

We also carefully remove the gas hose indicated by the arrow

The carburetor is finally disconnected, it is ready for adjustment. Its mechanism is quite complicated, therefore, if further disassembly of the carburetor is required, the elements should be removed very carefully. they are small, therefore they can be lost.

The carburetor consists of many small parts that should be laid out in order during disassembly

Features of adjustment and adjustment

To learn how to adjust the carburetor on a chainsaw, you should learn to distinguish between three screws (some models have only one).

Screws L and H are similar only in appearance, in fact they are different

Each screw has its own letter designation:

  • “L” is used to set low revs;
  • "H" is necessary to adjust the upper revs;
  • “T” is needed to adjust the idle speed (only one model is present on models with one screw).

Factory adjustment is optimal, and with the help of screws adjust the engine in special situations (work associated with different climatic conditions).

The diagram shows the outputs of the carburetor adjustment screws with the lid closed

A special tool is used to set up the chainsaw

The adjustment is carried out only with screws L and N. To increase the speed, they are rotated clockwise. To lower. counterclockwise. The sequence of use of the screws: L. H. T.

If you have doubts about the adjustment, it is better to consult a specialist, as improper tuning can damage the engine.

Bad Start Saw Partner 350

Today, it is probably difficult to find a host who does not have such a universal, practical, and multifunctional tool as a chainsaw. This device is deeply rooted in everyday life, and this is not surprising because a chainsaw has become for us simply an indispensable assistant in the field of cutting wood of various nature, harvesting firewood for the winter, sawing trees, and it is also used in the construction industry, etc. Naturally about its positive sides can talk endlessly and she is doing just fine with her task. But, like any technique, no matter how unique and highly practical it is, over time it fails and stops starting, and this is normal. The most important thing at this moment is to correctly determine the cause of the malfunction and quickly eliminate it.

Naturally, you can contact all kinds of services that for a fee will put your equipment in order. But at the same time you have to pay a significant cost. What for? After all, you yourself can try to determine the degree and cause of the breakdown and fix it.

Since there are such minor breakdowns that can be fixed within five minutes. It is about them and how to eliminate them that we will discuss in this article.

Factory device

The first and practically the main element of the chainsaw is the engine, namely the two-stroke carburetor (see carburetor adjustment). Its direct power is diverse, it all depends on the model of the device and its direct purpose. For example, the power of the Ural chainsaw is 3.68 kW.

The second equally important part of the tool is headset (saw) which consists of a chain (cutting), tires, sprockets, wheels (chain). To this it is worth adding that completely different manufacturers provide their own specific range of this headset.

It is also important that it must always be selected directly specific engine characteristic data. Since the larger the headset this type of headset has, the deeper the notch of the chainsaw will be, you can even say that the more powerful and productive it will be. But do not forget that for the full operation of the device, the engine also should not be inferior to it in power.

Its lubrication is carried out by means of a special oil directly from the second tank, which is located on the hand unit. It is worth noting that the mass of this kind of tank has such features that oil and fuel, which is designed for the engine to end at the same time.

In general terms, we figured out the device, but most likely its foundation, and now it’s time to begin to understand why the chainsaw stopped working, what could be the reason and how to eliminate them.

Reasons and solutions

Undoubtedly, after reading this heading, you continue to read this paragraph and this is not surprising.

Since most owners of chainsaws, one can even say with some degree of certainty that almost every owner is faced with the fact that the device either does not start at all, or there are "signs of life", but it immediately stalls.

In fact, there are many reasons for this kind of malfunction in the tool, and now we will try to deal with the main ones. So let’s get started:

The chainsaw starts and stalls immediately

The cause of this kind of malfunction may be the pouring of a direct candle at the very moment when you are trying to start a chainsaw. Since a significant amount of gasoline is collected precisely between the electrodes of the candle, therefore, a spark cannot be created. You can fix this kind of failure yourself, and you do not have to contact specialized services.

To do this, simply turn out the candle itself and dry it. You can also try to produce heat, this will not be superfluous, but remember that this kind of manipulation must be carried out exclusively through a gas burner.

Otherwise, a specific deposit may occur on the surface of the direct electrodes. In the meantime, while your candle dries, you need to drain the excess fuel directly by using the hole and let it dry for about half an hour.

Starts up cold

The answer to this question is unequivocal. there is no compression. This happens. the rings, most likely through long operation, simply worn out, therefore, when you try to start the device directly in the cold state, then not enough compression to run directly.

But taking into account the fact that the majority of “literate” people begin to systematically pull the handle, while the rings produce friction on the sleeve, therefore, oil and gasoline fall on them, the compression ratio rises and the engine starts. And when the chainsaw is already warmed up, then of course it will start.

Video: Bad Start Saw Partner 350


But this kind of manipulation is harmful enough for the device, since just a few times you will achieve the desired effect through such actions, but the time will come when the chainsaw can finally break. Therefore, the best thing you can do is change the rings that are already worn out. This is not a complicated process, so you can completely cope with it yourself without using the services of a service.

Why does not start on hot

Before you begin to solve this problem, it should be noted that the productive and proper operation of the engine depends primarily on speed through the application of the starter mechanism. In most models, this “minimum” level is 800 rpm. It is important that the main reason for the "not factory" chainsaw is normal engine flooding.

Bad Start Saw Partner 350

In order to eliminate this problem, it is necessary first of all to put the damper (air) in the middle position. After that, blow a couple of times to get a chainsaw. After the process has started, warm it up within ten seconds, and then transfer it to the idle mode. After carrying out these manipulations, you can fully open the damper (air).

After this, it is worth noting that before starting the immediate implementation of actions regarding the “prescribed recommendations”, try to start the device directly in the idle position. To do this, just pull the "rope". Since in that case, if not a hot engine, the plant will be produced without any problems.

But if you do not succeed, it means that it is already quite cooled. In this case, fix the half-gas according to the instructions in the instructions that came with your chainsaw.

But if this does not help, in this case, you should directly rotate the cold-running screw, directly clockwise.

Remember that the higher the RPM level in your device, the easier it will be for you to start the device. And remember that the chain must be stationary relative to the cold running.

Chinese chainsaw does not work

First of all, what I would like to note is that Chinese devices are quite reliable and powerful, at least, as practice shows. And the reasons for its breakdowns are not much different from all other models from other manufacturers. But there is one feature that does not tolerate negligence regarding chainsaws of Chinese manufacturers, namely fuel that is poured directly into it.

It is the low quality of the fuel and oil that are used to prepare the mixture that is the main and probably the only reason that you can’t get a Chinese-made chainsaw.

Since many "wise men" believe that the main thing to fill in and what to fill does not matter, it will do. And then they wonder why the device does not work.

Therefore, special efforts to eliminate this problem are not needed, simply use oil and gasoline from the manufacturer who created your chainsaw and everything will be fine. See the video for more details:

A new chainsaw won’t start

In fact, in principle, there should be no problems with the new chainsaw, since all spare parts are only from under the machine and are not subject to wear. The only reason that the device does not work can be either a factory defect or you are doing something wrong with respect to the instructions of the instruction. In order to eliminate this kind of problem, carefully check whether you have "screwed and attached" everything correctly. This can be with any equipment, with the Russian Lesnik chainsaw, not inferior to it as a patriot chainsaw, as well as the powerful Partner 350 saw,

In addition, an important factor in the malfunction of the tool may be that you have prepared the mixture in erroneous proportions, consisting of oil and gasoline. Either you filled in such basic "additives" of poor quality, which certainly affects the operation of the chainsaw, or the manufacturer who produced your tool.

Once again, carefully read the instructions, and then check up to a millimeter every action with a chainsaw. Read the instructions on how to properly run a chainsaw.

The spark is, the candle is wet

First of all, it is necessary to remove the muffler and carefully inspect the piston, since this is where the problem may be hidden. In addition, most owners wonder: why does the chainsaw start and stall, while there are supposedly no problems with candles?

But this is an erroneous opinion and one does not need to be so sure in this case, so there are situations when the candle perfectly sparks in air, but does not work directly in the cylinder.

The reason for this may be an immediate violation of a kind of compaction in the area of ​​the channel (impulsive). Or so there is a peculiar development of crankshaft oil seals, but this feature is found in very rare cases.

But if you notice a similar malfunction of your chainsaw, then do not put off the repair in a long drawer and it is best if it will be done by professionals. Otherwise, you simply can simply “break” the piston.

The price of Stihl chainsaws starts from 8000-10000 rubles. over, they are world leaders in the production of chainsaws.

The Stihl ms 660 chainsaw is the most economical of the entire Stihl range of chainsaws. Its price ranges from 3,100 to 5,500 rubles.

To summarize

Damage to technology is undoubtedly a very unpleasant and distressing event for its owner. But do not despair ahead of time, because if your chainsaw is being repaired, then this is just a matter of time. In this article, you were able to familiarize yourself with the most common problems regarding chainsaw malfunctions, as well as options for resolving them at home.

Most importantly, if you want your tool to always be in working condition, and there are no problems with its operation, just for easy follow the technique. Often look directly into its “inner” area. Maybe some part will wear out soon, maybe you need to clean something, etc. Read how to sharpen the chain with your own hands.

In fact, this kind of manipulation is not complicated and can be done periodically. But this is a “plus” for you in the first place, since a breakdown will not catch you at the most inopportune moment, when you need to do a huge amount of work and you do not have to spend time solving problems related to breakdown.

We also recommend that you familiarize yourself with the Swiss company producing Husqvarna chainsaws.

Partner 350 Does Not Start Candles

Among the huge selection of models in the modern construction market, the Partner 350 chainsaw, which is produced by a subsidiary of Husqvarna, stands out.

Partner 350 Does Not Start Candles

General view of the Partner 350 chainsaw

Simple and easy to use, reliable and unpretentious, this saw has gained wide popularity among summer residents and owners of country houses. Sawing firewood, trimming trees and twigs. this is not the whole list of works with which this model can cope without problems. Despite the thoughtful design and layout of the units, over time, the power unit, transmission elements and the fuel system wear out.

Chainsaw Troubleshooting

Experienced loggers know that a competent and accurate determination of the nature of the breakdown is half the repair work done. Based on the long-term experience in repairing the Partner 350 chainsaw, specialists developed a special method for diagnosing problems.

The main breakdowns of the Partner 350 chainsaw

It starts from the simplest nodes and mechanisms, ending with more complex ones.

This allows you to significantly save time and avoid unnecessary operations. Troubleshooting is recommended in the following order:

  1. Checking the spark of a chainsaw;
  2. Ignition coil;
  3. Diagnostics of the fuel supply system;
  4. Inspection of crankshaft bearings.

Checking sparks on candle electrodes

To diagnose the presence of a spark, it is necessary to remove the spark plug and, without removing the high-voltage cable, make a few jerks with a starter. If there is a discharge, it will be necessary to set a gap between the central and side electrodes. Its value in Partner 350 should not extend beyond 0.7 to 1.2 mm.

Probe clearance adjustment

The lack of this distance can lead to incomplete combustion of the fuel mixture and, as a consequence, increased fuel consumption with limited power of the unit. As a result of exceeding this parameter, inconsistencies in the occurrence of sparks and interruptions in the operation of the internal combustion engine are observed.

If there is no spark on the electrodes, it is necessary to replace the spark plug and repeat the diagnostic procedure described above.

If discharge is also not observed on the replaceable candle, it is necessary to check the integrity of the high-voltage wire and replace it if necessary.

Diagnostics and tuning ignition Partner 350

The absence of a bright blue spark in the candle may indicate the need to inspect the ignition module and adjust the clearance. For these purposes, remove the plastic protective cover from the saw and check the condition of the coil. The wires leading to it should be firmly fixed with screws and should not hang out at the junction. Moisture must not be present on the flywheel of the drive shaft, since it prevents the occurrence of an electromagnetic field.

Partner 350 flywheel and ignition module

In the absence of such discrepancies, it is necessary to make sure that the clearance between the module and the flywheel is set correctly. Its value should be no more and no less than 0.2 mm, and therefore, if it does not coincide with the recommended distance, you must independently configure the ignition of the Partner 350 chainsaw.

After checking the ignition, we proceed to the diagnosis of the fuel supply system.

350 chainsaw fuel system

An important influence on the correct operation of the saw is played by the fuel system, consisting of a gas tank, pipes and a carburetor.

Partner 350 carburetor parsed

If the mixture does not come from the tank, it is necessary to inspect the built-in filter and breather (hole in the cover). If the fuel filter is clogged, it will need to be replaced. To clean the breather, you can use a regular sharp needle, carefully removing the remaining dirt and sawdust from the valve. If the carburetor becomes clogged, it will need to be dismantled and thoroughly cleaned.

It must be remembered that the Partner chainsaw carburetor is a complex assembly consisting of many small parts. Therefore, during dismantling, cleaning and assembly, maximum attention is required.

Carburetor principle

The carburetor is used to mix the fuel mixture (oil and gasoline) with air. His work begins from the moment the jerk of the starter jerks, which forces the membrane to pump fuel. After that, a diaphragm-controlled needle valve delivers gasoline to the main chamber, through which it enters the cylinder. Through the throttle, you can "enrich" or "deplete" the fuel mixture with air. When it is closed, less air will flow into the cylinder at the same fuel level. In this case, the consumption will be increased, coupled with a decrease in engine power. Therefore, adjusting the Partner 350 chainsaw plays an important role in creating the optimal ratio of moderate fuel consumption with high tool productivity.

It is recommended to perform self-tuning only with special tools and skills.

DIY carburetter for Partner 350

Before starting adjustment work, it is necessary to clean the main fuel assembly from dust and dirt. To do this, you can use a compressor with compressed air or a carpentry brush.

To adjust the carburetor, holes are provided on the left side of the power unit, however, for the convenience of determining their position, experts recommend dismantling the protective plastic casing. First, we tighten the fuel quantity and quality screws clockwise until they stop, loosening them after 1/5 ¼ revolution.

Partner 350 chainsaw carburetor with setting screws

When dismantling the cover, you need to know that the fuel mixture quality screw is on the right and, accordingly, the gasoline quantity adjustment screw is on the left. For convenience, on the carburetor body under the bolts is marked:

It must be remembered that the carburetor adjustment of the Partner 350 chainsaw must be carried out on a warm engine. At high temperatures, the metal expands linearly, resulting in increased channel throughput.

As soon as the cylinder becomes warm, tighten the screw “L” until the internal combustion engine gives out the maximum revolutions of the crankshaft. After we twist it a quarter of a turn. It should be noted that in this position the screw of the mixture supply quantity should support the engine idling. If such a setting is not enough, then boldly unscrew the “T” bolt until the engine runs stably. Using the “H” screw, we adjust the operation of the Partner chainsaw at maximum speed.

Crankshaft Bearing Diagnostics

An important factor in the correct operation of the engine are bearings and crankshaft oil seals.

Partner 350 crankshaft with bearings

To diagnose their wear, a flywheel mounted on the shaft must be swayed in the vertical and horizontal plane. If there is a clear play, it is necessary to replace the rolling bearings. If there are oily traces on the crankcase, then the oil seals will need to be replaced. It will not be superfluous to check the play of the Partner 350 crankshaft, for which we remove the cylinder and piston. With the help of hands we shake it left and right, thereby simulating a natural movement.

Conclusion

Despite some difficulties in repairing the Partner 350 chainsaw with their own hands, the owners of these units, before handing over the tool to specialized centers, try to restore their performance on their own. Indeed, most of the problems can be eliminated with ordinary metalwork tools and with the presence of basic experience in the repair of mechanical components.

Idle Adjustment Partner 350

Carrying out repairs and summer house construction can not do without the use of a chainsaw, this statement is also true when caring for the garden. If the tool turns out to be faulty, then all the work will arise because of this, so it is so important to have the skills of self-identification and troubleshooting. If you have some experience, then you will be able to adjust the carburetor, although this procedure is complicated, it is quite doable.

The need for adjustment

Idle Adjustment Partner 350

Adjustment of the carburetor of the Partner-350 chainsaw is required in rare cases, most often there are problems expressed in the wrong fuel intake or engine wear. But there are signs that it is necessary to adjust the mechanism, here are some of them. After it was possible to start the engine, it immediately stalls. In some cases, users can’t start it at all, and the reason lies in the lack of fuel or an excess of oxygen. A problem may arise in the case of increased fuel consumption, the result is an increase in the volume of exhaust gases. This may occur due to oversaturation of the mixture with fuel.

Mechanical causes of failure

Adjustment of the carburetor of the Partner-350 chainsaw may be necessary in case of mechanical failures. For example, a protective cap may be damaged due to strong vibrations. Ultimately, the bolts in the carburetor lose their fixation. The piston part of the motor may also wear out. The carburetor setting helps in this case for a certain time, to eliminate the problem you need to replace the worn part. The cause may be a blockage that occurs due to the use of low quality fuel. Damage to the filter and build-up of scale can lead to such consequences. At the same time, the carburetor will need to be disassembled, rinsed well and adjusted.

Disassembly

If you will be adjusting the carburetor of the Partner-350 chainsaw, then you should familiarize yourself with the assembly of the unit in more detail, in many models the design features almost do not differ from each other, so the recommendations given will turn out to be relevant.

Elements must be removed with maximum accuracy, stacking them in order, during the assembly process this will help you. Three bolts hold the top cover, they must be removed, then you will see a layer of foam, which acts as part of the air filter. The master will have to get rid of the fuel hose, this will remove the drive traction.

Partner-350 chainsaw carburetor adjustment is not possible, if you do not remove the cable end, this should be done in the next step. The gas hose, which is located to the left of the fitting, will need to be thrown off. All of the above work will allow you to disconnect the carburetor, which can be adjusted. This mechanism is complex, so if you need further disassembly, you need to remove the elements carefully, because their size is very small, because of which they can easily be lost.

Adjustment

If you have a “Partner-350” saw, carburetor adjustment can be done independently, without the involvement of specialists. Having assessed your capabilities and experience, proceed with the disassembly, the recommendations for which were presented above. Then you can carry out the adjustment and subsequent adjustment. It is necessary to distinguish three screws, exactly in such quantity they are available for the “Partner” saw, however, in some models the screw is installed in a single copy. The manufacturer has designated each with its own letter, which will allow you to understand what the element is for. Thus, the screw under the letter L must be used when setting low revs. The upper revolutions can be corrected with a screw under the letter H. Idling can be adjusted with a screw under the designation T, for other models only it can be present.

Additional recommendations

If you purchased the Partner-350 saw, carburetor adjustment can be carried out during operation. Before carrying out these works, you must remember that the factory settings are optimal. Using the screws described above, you can adjust the operation of the motor in special situations, among them different climatic conditions can be distinguished. When adjusting, it is necessary to use screws under the letters L and N. To increase the speed, they should be turned clockwise.

To lower the revolutions, the screws rotate in the opposite direction. It is important to take into account the sequence of use of the elements, which is as follows: L. H. T. If you encounter difficulties during the adjustment, it is best to consult a specialist, because an incorrect setting can damage the motor.

Need adjustment

In order to understand how to adjust the Partner-350 chainsaw, it is best to first familiarize yourself with the device of this unit in more detail at the first stage. If you understand the principle of operation and components, you will be able to independently determine the cause of the breakdown. The carburetor acts as one of the main parts of the engine, which is necessary for the preparation and subsequent supply of fuel, the latter consists of fuel and oxygen. If the ratio of these ingredients is violated, the motor may begin to work incorrectly, and subsequently fail.

Carburetor device

If you decide that you need to adjust the Partner-350 saw, then you first need to study the design of the elements. The system consists of a diffuser, which acts as a constriction to increase the oxygen flow rate. The diffuser is in close proximity to the inlet through which fuel is supplied. There is also a tube with a transverse flap in the carburetor, it is necessary to regulate the flow of oxygen. Fuel comes from a spray, it is presented by a needle. To adjust the fuel at the entrance to the channel, a float chamber is needed, it is also available in the carburetor device.

Principle of operation

If you purchased a Partner-350 chainsaw, carburetor adjustment may be necessary during operation. In order to carry out these actions correctly, you must also familiarize yourself with the principle of operation of this item of equipment. The fuel is sprayed in the diffuser with a stream of air, which allows you to create a mixture pumped into the cylinder. The larger the fuel flow, the higher the engine speed. In the described model, as in any other, the carburetor works according to the same scheme described above.

Ignition adjustment

For those people who have a Partner-350 saw, the ignition is adjusted quite often. At the first start-up, idling needs to be checked; in order to perform it, it is necessary to turn the screw that is responsible for adjusting idling clockwise. Once it rests, it should be turned counterclockwise by 4.5 turns. If, after carrying out these manipulations, the motor runs without chain rotation, then everything is in order. Otherwise, you need to contact a service center, as working with such a saw can be dangerous.

Poulan Partner 370 Chainsaw Carb Adjustment

All malfunctions of chainsaws can be divided into two main groups: malfunctions of the engine with all its components and systems (ignition, fuel supply system, cylinder-piston group, exhaust system) and malfunctions of other components (chain brake, lubrication system, clutch, tire, etc. ).

Engine malfunctions

  • The engine will not start;
  • Starts up, but stalls;
  • unstable;
  • does not develop power, i.e. normally works at idle, but stalls under load.
Poulan Partner 370 Chainsaw Carb Adjustment

When repairing a chainsaw with your own hands, you need to act by the method of exclusion. check alternately all possible causes of the malfunction, starting with those that take less time to check and eliminate (see here for the design and operation of a two-stroke engine).

Ignition system. Almost all types of engine malfunctions listed above can be caused by ignition system malfunctions. Therefore, when they occur, it makes sense to start troubleshooting with a candle. This is all the more justified because the state of the latter can provide useful information about the operation of the fuel system. So, if a problem occurs, you need to turn out the candle and inspect it.

The wire is disconnected, and the candle is twisted with a special key.

If the candle is dry, it means that the problem is most likely not in the ignition system, but in the fuel mixture not entering the cylinder. You can wrap the candle back and take up the fuel system. If the candle is heavily sprayed with the fuel mixture, then there is an excess of it. This may occur due to misregistration of the carburetor or violation of the rules for starting. The candle is wiped and dried, the cylinder is drained, cutting off the fuel supply and working as a starter. to vent the combustion chamber and remove excess fuel. Then set the candle in place and repeat the launch.

The presence of a large amount of black soot also indicates a malfunction in the fuel system.

The ratio between oil and gasoline in the mixture may be violated, the carburetor is not adjusted, or poor-quality oil is used. The candle is washed in gasoline, cleaned with a needle or an awl of carbon deposits, clean the electrodes with a fine sandpaper and put in place.

In all these cases, it is not superfluous to check the gap between the electrodes of the candle. Depending on its brand, it should be in the range of 0.5-0.65 mm. It is necessary to check the sealing gasket of the candle. If it is worn or damaged, the tightness of the combustion chamber may not be ensured, which leads to a decrease in compression in the cylinder and problems in the engine.

Even if in the case of checking the spark plug there is good reason to believe that the fault is in the fuel system, you need to check the spark plug for a spark. At least in order to be sure that everything is in order with this. For this:

  • put on the spark plug cable;
  • using pliers with insulated handles, apply thread or nut to the cylinder;
  • pull the starter handle and look. there is a spark or not.

If there is no spark, you just need to replace the candle. If the new candle does not have a spark, it is necessary to check the condition of the high-voltage wire for an open and contact with the candle.

The reason for the absence of a spark can also be a faulty ignition module or a violation of the gap between it and the flywheel magnetic circuit. It should be 0.2 mm. Violation of the gap becomes especially likely if before that the saw was disassembled with the flywheel and the ignition module removed. The clearance is set using a 0.2 mm thick gasket placed between the flywheel boss and the ignition module. Defective ignition module must be replaced.

Having checked the ignition system in this way and not having detected a malfunction, we can proceed to the fuel mixture supply system.

Fuel supply system. If inspection of the spark plugs found that fuel does not enter the cylinder, you need to consider all the possible reasons for this. It could be:

  • non-receipt of fuel from the tank due to a clogged hole in its cap (breather), while a vacuum is created in the tank that prevents fuel from flowing out;
  • contamination of the fuel filter installed in the tank;
  • not receipt or insufficient supply of fuel mixture from the carburetor to the cylinder.

To diagnose the first two reasons, it is enough to disconnect the fuel hose from the carburetor and see if fuel flows out of it or not. If it flows fully, the breather and filter can not be checked, if it does not or weakly flows, we can assume that the cause of the malfunction is found. The breather is cleaned with a needle. The fuel filter is removed through the filler hole of the empty fuel tank with a wire hook, together with a suction hose, from which the filter is disconnected and cleaned or replaced with a new one. Chainsaw manufacturers recommend changing the fuel filter every 3 months.

An insufficient supply of the fuel mixture from the carburetor to the cylinder or a violation of the correct ratio between the fuel and air mixed in the carburetor can occur for several reasons: due to clogging of the air filter, unregulated carburetor, clogging of its channels or mesh filter.

As a rule, repairing chainsaws is not complete without cleaning the air filter, since it gets dirty quite quickly. When this happens, air intake to the carburetor decreases, the fuel mixture at the outlet of it turns out to be too enriched, which disrupts the normal operation of the engine. Carefully remove the dirty filter for cleaning so that dirt does not get into the carburetor. The filter should be cleaned or washed in water with some detergent, dried and installed again.

Carburetor misregistration is eliminated by its adjustment. This is usually done with three screws. maximum and minimum idle speed and propeller. Adjustment must be carried out in strict accordance with the instructions, non-observance of which can lead to engine damage. Some saw manufacturers leave only one adjusting screw (idle). to exclude unwanted interference by inexperienced users in the carburetor. For an example of adjusting the carburetor of a chainsaw, see the article Working with a chainsaw.

If the carburetor adjustment did not help, you need to clean its channels and filter mesh, and at the same time check the integrity of the membrane. Carburetor. one of the most complex chainsaw devices, so proceed with disassembling and cleaning it with a full understanding of the responsibility of this operation. It consists of many small parts that have the peculiarity of quietly popping out of their seats and irretrievably lost, so that, having disassembled this capricious device, you can not assemble it.

Below is a diagram of another carburetor chainsaw.

If there is no experience and self-confidence, it is better to entrust the repair of a chainsaw carburetor to a service center specialist. Sometimes for high-quality cleaning of the carburetor it is necessary to apply ultrasonic cleaning.

Muffler. Often the cause of engine malfunction, especially in the case when the engine is operating normally at low revs and stalls under load, becomes clogging of the silencer’s spark arrester, which prevents normal exhaust, from the combustion products. Repair in this case consists in removing the muffler, disassembling (if it is collapsible) and wet cleaning it from soot using detergents. The non-separable muffler is dried with a hairdryer after washing. Remember that soot contains substances that are carcinogens, and dry cleaning, which may cause inhalation, is unacceptable. When removing the muffler, the engine outlet is plugged with a clean rag.

One of the reasons a muffler may clog. this is the use of a fuel mixture with an excessive amount of oil (the amount of oil is more than recommended by the manufacturer), and the use of either non-suitable oil for two-stroke engines or low-quality oil.

Cylinder piston group. Malfunctions of the cylinder-piston group are the most serious. This is the deterioration of the cylinder and piston, scratches and seizures on their surface, wear or sinking in the grooves of the piston rings, wear of the crankshaft bearings. Most of these malfunctions lead to a drop in pressure in the cylinder and, as a consequence, to the inability to start the engine, or its inability to give full power. There are several ways to assess the status of a cylinder-piston group (CPG).

You can remove the muffler and look through the opened window, in which a part of the side surface of the cylinder is visible. Despite the limitations of the review, a general idea of ​​the state of the CPG in this way can still be obtained.

It is useful to measure the compression in the engine, which is quite informative regarding the condition of the parts of the CPG. The operation is carried out using a compressor installed in the candle hole.

The crankshaft is rotated using an electric motor (drill) with a flexible shaft or manually by a starter, while controlling the pressure on the pressure gauge. The last for a workable chainsaw should be at least 8-9 atm (0.8-0.9 MPa). With its decrease, engine power also drops. At a pressure of 5 atm, the engine may perhaps work, but only at idle.

It is possible to accurately assess the state of the CPG only by completely disassembling the engine. disconnecting the crankcase from the cylinder and removing the piston. If the latter has scuffs, chips or deep scratches, it must be changed. In relation to the cylinder, when developing or damaging the surface, it is possible to squander it under the repair size. The cause of low compression may be wear and coking of the piston ring. The serviceable ring should be clean of carbon deposits, sit in the piston groove freely and firmly pressed against the inner surface of the cylinder.

Chain lubrication system

With a significant (small is considered normal) oil leakage, it is necessary to check the tightness of the connection of the tubes to the pump fittings. They may fall or crack. Violation of the tightness of the oil pipe, in addition to sagging, can lead to insufficient lubrication of the chain. The pump begins to suck in air, which affects its performance. The leak is eliminated by replacing the tubes or sealing them with sealant.

The most serious damage to the lubrication system are cracks in the oil pump housing. In this case, it will have to be replaced.

Chain brake

Replacing Wear Parts

If you do not replace the wearing parts in time, their excessive wear will adversely affect the other parts of the chainsaw. In particular, if you do not change the tire and the drive sprocket in time, increased vibration will adversely affect the crankshaft bearings. The maximum depth of the tooth teeth should be 0.5 mm. In practice, sprockets are often operated up to a wear depth of 1 mm or more. not suspecting that this leads to an increased load on the crankshaft bearings and their accelerated failure. When 3-4 chains are worn, it is necessary to change the tire itself, by this time its wear reaches its limit values.

The chainsaw tire wears out especially in the area most often cut, usually. this is the underside of the guide rail. For uniform wear, each time the chain is replaced, the tire must be turned 180 ° relative to the horizontal axis.

When installing a new chain, a new drive sprocket should be installed. Since under normal load the service life of the drive sprocket is twice as long as the service life of the chain, it is advisable to use one sprocket for alternating operation of two chains. Thanks to this, the sprocket and chains wear out almost simultaneously. If a new chain is placed on a worn sprocket, then the leading chain links wear out much faster. For cost-effective operation of the chainsaw, always spend together: one guide bar, two chain sprockets, four saw chains.

Partner 350 Chainsaw Carb Adjustment

Among the huge selection of models in the modern construction market, the Partner 350 chainsaw, which is produced by a subsidiary of Husqvarna, stands out.

Partner 350 Chainsaw Carb Adjustment

General view of the Partner 350 chainsaw

Simple and easy to use, reliable and unpretentious, this saw has gained wide popularity among summer residents and owners of country houses. Sawing firewood, trimming trees and twigs. this is not the whole list of works with which this model can cope without problems. Despite the thoughtful design and layout of the units, over time, the power unit, transmission elements and the fuel system wear out.

Chainsaw Troubleshooting

Experienced loggers know that a competent and accurate determination of the nature of the breakdown is half the repair work done. Based on the long-term experience in repairing the Partner 350 chainsaw, specialists developed a special method for diagnosing problems.

The main breakdowns of the Partner 350 chainsaw

It starts from the simplest nodes and mechanisms, ending with more complex ones.

This allows you to significantly save time and avoid unnecessary operations. Troubleshooting is recommended in the following order:

  1. Checking the spark of a chainsaw;
  2. Ignition coil;
  3. Diagnostics of the fuel supply system;
  4. Inspection of crankshaft bearings.

Checking sparks on candle electrodes

To diagnose the presence of a spark, it is necessary to remove the spark plug and, without removing the high-voltage cable, make a few jerks with a starter. If there is a discharge, it will be necessary to set a gap between the central and side electrodes. Its value in Partner 350 should not extend beyond 0.7 to 1.2 mm.

Probe clearance adjustment

The lack of this distance can lead to incomplete combustion of the fuel mixture and, as a consequence, increased fuel consumption with limited power of the unit. As a result of exceeding this parameter, inconsistencies in the occurrence of sparks and interruptions in the operation of the internal combustion engine are observed.

If there is no spark on the electrodes, it is necessary to replace the spark plug and repeat the diagnostic procedure described above.

If discharge is also not observed on the replaceable candle, it is necessary to check the integrity of the high-voltage wire and replace it if necessary.

Diagnostics and tuning ignition Partner 350

The absence of a bright blue spark in the candle may indicate the need to inspect the ignition module and adjust the clearance. For these purposes, remove the plastic protective cover from the saw and check the condition of the coil. The wires leading to it should be firmly fixed with screws and should not hang out at the junction. Moisture must not be present on the flywheel of the drive shaft, since it prevents the occurrence of an electromagnetic field.

In the absence of such discrepancies, it is necessary to make sure that the clearance between the module and the flywheel is set correctly. Its value should be no more and no less than 0.2 mm, and therefore, if it does not coincide with the recommended distance, you must independently configure the ignition of the Partner 350 chainsaw.

After checking the ignition, we proceed to the diagnosis of the fuel supply system.

350 chainsaw fuel system

An important influence on the correct operation of the saw is played by the fuel system, consisting of a gas tank, pipes and a carburetor.

Partner 350 carburetor parsed

If the mixture does not come from the tank, it is necessary to inspect the built-in filter and breather (hole in the cover). If the fuel filter is clogged, it will need to be replaced. To clean the breather, you can use a regular sharp needle, carefully removing the remaining dirt and sawdust from the valve. If the carburetor becomes clogged, it will need to be dismantled and thoroughly cleaned.

It must be remembered that the Partner chainsaw carburetor is a complex assembly consisting of many small parts. Therefore, during dismantling, cleaning and assembly, maximum attention is required.

Carburetor principle

The carburetor is used to mix the fuel mixture (oil and gasoline) with air. His work begins from the moment the jerk of the starter jerks, which forces the membrane to pump fuel. After that, a diaphragm-controlled needle valve delivers gasoline to the main chamber, through which it enters the cylinder. Through the throttle, you can "enrich" or "deplete" the fuel mixture with air. When it is closed, less air will flow into the cylinder at the same fuel level. In this case, the consumption will be increased, coupled with a decrease in engine power. Therefore, adjusting the Partner 350 chainsaw plays an important role in creating the optimal ratio of moderate fuel consumption with high tool productivity.

It is recommended to perform self-tuning only with special tools and skills.

DIY carburetter for Partner 350

Before starting adjustment work, it is necessary to clean the main fuel assembly from dust and dirt. To do this, you can use a compressor with compressed air or a carpentry brush.

To adjust the carburetor, holes are provided on the left side of the power unit, however, for the convenience of determining their position, experts recommend dismantling the protective plastic casing. First, we tighten the fuel quantity and quality screws clockwise until they stop, loosening them after 1/5. ¼ revolution.

When dismantling the cover, you need to know that the fuel mixture quality screw is on the right and, accordingly, the gasoline quantity adjustment screw is on the left. For convenience, on the carburetor body under the bolts is marked:

It must be remembered that the carburetor adjustment of the Partner 350 chainsaw must be carried out on a warm engine. At high temperatures, the metal expands linearly, resulting in increased channel throughput.

As soon as the cylinder becomes warm, tighten the screw “L” until the internal combustion engine gives out the maximum revolutions of the crankshaft. After we twist it a quarter of a turn. It should be noted that in this position the screw of the mixture supply quantity should support the engine idling. If such a setting is not enough, then boldly unscrew the “T” bolt until the engine runs stably. Using the “H” screw, we adjust the operation of the Partner chainsaw at maximum speed.

Crankshaft Bearing Diagnostics

An important factor in the correct operation of the engine are bearings and crankshaft oil seals.

To diagnose their wear, a flywheel mounted on the shaft must be swayed in the vertical and horizontal plane. If there is a clear play, it is necessary to replace the rolling bearings. If there are oily traces on the crankcase, then the oil seals will need to be replaced. It will not be superfluous to check the play of the Partner 350 crankshaft, for which we remove the cylinder and piston. With the help of hands we shake it left and right, thereby simulating a natural movement.

Conclusion

Despite some difficulties in repairing the Partner 350 chainsaw with their own hands, the owners of these units, before handing over the tool to specialized centers, try to restore their performance on their own. Indeed, most of the problems can be eliminated with ordinary metalwork tools and with the presence of basic experience in the repair of mechanical components.

Replacing the Oil Pump On a Partner 350 Chainsaw

The Partner 350 chainsaw is a “relative” of the famous Husqvarna brand, as Partner is a subsidiary of Husqvarna. Light and convenient, reliable and simple, Partner 350 has been widely used in cottages and in private households. Cutting of knots, branches, felling trees is far from a complete list of work that is performed easily and easily by a saw. A brief overview will help you get acquainted with this in more detail.

Replacing the Oil Pump On a Partner 350 Chainsaw

Specifications

According to its data, Partner 350 belongs to the type of household (amateur) and fully satisfies the needs of any consumer. For a general familiarization with a chainsaw, just look at its main characteristics.

For those familiar with chainsaws, one glance is enough to determine the character of the 350 Partner. A sufficiently powerful engine and a decent tire length indicate that it will be an indispensable assistant in the economy, but it hardly fits for a professional felling.

Device

The general device is made in a traditional style. It is characterized by simplicity, which means high reliability of the unit.

The scheme of the general device of the Partner 350 chainsaw clearly confirms this.

Starting the engine is simple and reliable. This was made possible thanks to the presence of electronic ignition. The primer (fuel booster pump) plays an important role during start-up.

The air filter is equipped with a double air purification system. As a result of equipping the starter drum with an impeller, large particles of debris do not reach the filter at all. Due to this, its service life is increased, and the degree of air purification is increased. In general, this favorably affects the operation of the engine.

The safety of handling a working saw is achieved by the presence of a chain brake operating in two modes. manual and automatic.

The oil pump is turned on only during sawing. This means that the chain lubrication system is in automatic mode. It must be borne in mind that different types of oils are used to lubricate the chain and prepare the working mixture. Learn what oil is used for Partner 350 chainsaw video will help

Saw chains. An Oregon 91P052E 3/8 ″ 1.3 mm 52 chain link is installed on the Partner 350 saw. Valid replacement analogues: Stihl 39970000052s and others. For example, Husqvarna 5776151-22. Make sure that with a chain pitch of 3/8 ″ and a groove width of 1.3 mm, the number of links does not exceed 52. Less (46. 50) is possible, more is not desirable.

The anti-vibration system on Partner 350 works somewhat harshly. Given that this saw is not intended for professional use, the system as a whole can be considered satisfactory. By the way, on subsequent models in this regard, significant improvements have been made.

Recommended components, parts, mechanisms and fuels and lubricants are not subject to replacement by analogues.

Preparing the saw for operation

Before starting work, it is necessary to set up the Partner 350 chainsaw. A properly prepared saw with a well-engineered engine does not cause any complaints from users. Unit configuration is simple. Before starting the engine, it is checked:

  • tire mount;
  • chain tension;
  • ease of rotation of the chain;
  • brake operation;
  • refueling and oil.

After that, the engine starts. Warming it up, you can get to work.

Pros and Cons of Partner 350 Chainsaws

Like any chainsaw mechanism has its pros and cons. The main positive will be the following:

  1. The product is a product of a well-known manufacturer. This indicates the quality of the saw and a developed service network.
  2. The engine is equipped with a primer, which makes it easier to start, especially in the cold season.
  3. The piston and engine cylinder are additionally treated with chrome, which improves their characteristics and helps to extend the life of the whole.
  4. The 350 partner’s light weight and relatively short tire make the saw easy to control.

Disadvantages, of course, exist, but they look insignificant against the general background. Somewhat difficult access to the air filter and the lack of visual observation of the level of weather lubrication do not. Those who installed an extended tire note low engine power. It `s naturally. It should be so. The triple violation committed. a design modification unauthorized by the manufacturer, additional engine load and a direct violation of the requirements of the operating instructions will certainly not improve the operation of the unit.

Major malfunctions and their elimination

The main malfunctions that can be fixed independently and methods for their elimination are described in detail in the “Operating Instructions”.

Engine does not start

In this case, check the gap between the spark plug electrodes. It should be 0.5 mm. At the same time, the electrodes must be cleaned of carbon deposits. In most cases, this is enough for the engine to start working again. To the same extent, the start-up is affected by the contamination of the carburetor, fuel and air filters. After washing them, the engine, as a rule, stops acting up. On the pages of the site and the Internet there are many photos and videos on the restoration of the engine.

The engine does not develop power (stalls under load)

To the previously listed reasons, one more is added. you need to adjust the carburetor or clean the muffler. Adjustment is made by adjusting screws. Detailed information on this issue can be found on the site. The video shows the process of detecting and repairing chainsaw failure.

Starter cord break

Partner 350 is quite common on the chainsaw, and on all chainsaws, so Partner 350 is no exception. This malfunction is not difficult to fix on your own. After watching the video, it becomes clear how the torn starter cord is replaced.

Open circuit

Mostly due to its overheating during operation. The cause of overheating is the lack of lubrication or the clogging of oil channels with dirt. First of all, all oil channels are cleaned, the inside of the chainsaw in the area of ​​the drive sprocket and tire groove is cleaned of debris (sawdust). Only then can a new circuit be installed. If a problem is found in the operation of the oil pump, the saw must be repaired in a specialized workshop.

User’s manual

The instruction contains recommendations, following which the owner of the Partner 350 chainsaw will not encounter problems when handling it. The safety measures and operating rules of the product during operation are described in detail. The issues of repair, maintenance and care of the Partner 350 chainsaw are highlighted.

Types of chainsaw repair that are allowed to do with your own hands are determined by the instruction manual. All other malfunctions are fixed in a specialized workshop.

The instruction manual should always be at hand, especially if this is your first chainsaw and you just bought it. First of all, be sure to read it, and resort to its help when questions arise in the process of handling the tool. Download and print the instruction manual for the Partner 350 chainsaw at the link below.

Reviews

Particularly conquered all the advanced Partner 350s chainsaw. She absorbed all the best from the base model and became a little more powerful, which positively affects its application. It has proven itself when used in subsidiary and farming enterprises.

The technical characteristics of the Partner 350 chainsaw and its budget price, along with the simplicity of design, have provided it with widespread use in personal households.
