How to make a Partner’s chainsaw ignition. Filters

The ignition system of the chainsaw. from the device to check the coil by the multimeter

I welcome you dear and most faithful readers of my blog. In the current article, I decided to see how to adjust the carburetor on a chainsaw. After all, it seems to me that you have repeatedly faced a problem that your “road” failed you when I needed it. DIY chainsaw repair with your own hands. And because we are economical and do not want to waste funds to what we can do ourselves, then let’s learn to regulate the carburetor on our chainsaws with our own hands, without recruitment of profiles of the repairmen. And how soon you will see, it is quite simple to do it. For you, even nothing special is useful to you, do it. I specifically saw the adjustment of the carburetors of all recognizable brands of saws, any of which has its tricks and aspects and for my gaze is the best information on the network!

To disassemble the Partner 350 chainsaw, a number of specialized tools will be needed:

  • key;
  • part for fixing the piston;
  • hexagonal fasteners Torx;
  • bolt for grozing nuts (gap);
  • Locksmith (screwdrivers, hammers, scanning).

The first stage of parsing a saw is the removal of external profiles and unscrewing the covers. Using the battery drill, the air filter and starter cover lids are removed. Additional mounts (in the form of screws) are unscrewed by screwdrivers. After removing the covering modules, it is worth cleaning the internal highways of the Partner 350 chainsaw from pollution and dust. The removal of the saw engine should be carried out extremely neatly, because this mechanism is responsible for the operation of the unit.

After the engine, you need to remove the silencer and flywheel. At this stage you will need a special bolt for the piston. The clutch of the chainsaw is removed in the direction of the chain for the convenience of further assembly. Under the clutch is the oil pump drive, it also needs to be removed.

Removing a flywheel from a crankshaft using a special groove is common among private craftsmen. The bolt is tightly capturing the main screw of the flywheel and accelerates the process of removing the part. The flywheel is removed from the shaft with a hammer blow.

Partner 350 chain assembly is assembled in the reverse order. Upon the return of each part of the saw to the starting position, it is worth checking the fixation of all fasteners and the entry of the nuts into the grooves. A feature of the design of the saw engine is that the cover of the main case is installed without laying, the gaps are protected by applying a layer of special hermetic material. Before applying sealant, it is worth cleaning the surface well for uniform distribution of the product.

The installation of a flywheel must be carried out no less delicately than the process of removing it. For the correct functioning of the part, it is necessary to ensure gaps between the mechanism and other details of the saw. The ignition coil must be connected to the flywheel so that they do not touch each other, but were associated with the help of magnetic contacts.

Device and principle of operation of the starter of the chainsaw

So let’s start!

Surprisingly, this is all that we will need.

First, get acquainted with the device of your saw. What you need to do for you first is to find where there are carts of the carburetor, which is also more important than nozzles. adjusting screws. Partner 350 chainsaw price from 5 adjustment of the chainsaw carburetor work. video. Usually there should be two or three screws. Partner 350 S adjustment settings, adjusting the Partner 350 chainsaw carburetor. Some of them regulates idle speeds, and the other two are low and the highest.

Specifically, they will need to be adjusted, or twisted, or unscrew them to enrich or impoverish the fuel mixture.

If you need to impover the mixture, then just twist the regulator clockwise, if you enrich, then respectively against.

To adjust the speed of rotation at idle, the screw that is responsible for this must either be twisted clockwise in order to increase the speed of revolutions, or, as you already guessed, in the opposite direction to reduce them.

Repair of the Partner 350 carburetor with your own hands

Without certain skills and special tools, for example, groops of various sizes or ultrasonic bathtubs, the repair of the Partner 350 carburetor is reduced to replacing the remote control.

The WT-891 carburetor repair kit can consist only of gaskets and diaphragms, and may include a complete set of all replaceable elements. It:

It is impossible to replace the full set without experience and tools, therefore, with independent repair, it is better to choose the first version of the remote control. If, after replacing the remote control and adjusting the carburetor, the Partner 350 chainsaw shows signs of a malfunction, then to solve the problem, it is better to contact specialists.

Adjustment of the Partner 351 chainsaw carburetor with your own hands

You can deal with the setting of the carburetor of the chainsaw of the Partner 351 chainsaw yourself. Its adjustment is carried out by three screws, marked Latin letters L, H and T. The letter t indicates a screw of idle settings, h. high speeds, l. low.

The process of rebuilding involves two stages: basic and final. The exact value of the rotation angles should be indicated in the detailed instructions for the operation of the chainsaw Partner 351.

To access the carburetor, you need to remove the top cover of the chainsaw

Adjusting screws l and h

Basic setting

  • Screw the screw t clockwise until it stops, and then turn in the opposite direction for 4.5 turns.
  • Twist the screws h and l carefully to the end, and then turn back for 2 revolutions.
  • If the motor does not stall at idle, the circuit does not move, the engine accelerates quickly and works smoothly, which means that the basic adjustment is enough. If not, accurate setting is necessary. The chainsaw should be started and warmed up for 5-10 minutes.

Idling

  • Smoothly turning the screw l in one and the other side, find the position in which the turns are maximum.
  • Turn the screw l for a quarter of a circle counterclockwise.
  • When the chain rotates at idle, the screw t is twisted to the left until it stops.
  • If after setting up the engine starts poorly or stalls quickly, it is necessary to unscrew the screw l for another half turn and again adjust the screw t.

Maximum turns

Screw h to wrap to the right until the highest revolutions are reached.

Partner 351 saw, according to the operating manual, has a rotation speed limit of 13,000 rpm. The excess of this indicator is unsafe for the engine and is manifested by characteristic interruptions in the ignition and “singing” of the ICE, which can be adjusted, gradually turning the adjusting screw in the opposite direction.

On a note! A decrease in the number of revolutions at load can be adjusted by tightening the screw H about 45 degrees.

Acceleration

Pressing the gas.rosopila gas trigger should increase the engine speed from the idle to maximum power smoothly and quickly. If the speed set is delayed, the screw L needs to be twisted counterclockwise by no more than 45 degrees around the circle.

After setting up acceleration and maximum speed, the operation of the chainsaw should be redeveloped at idle.

Tools

In order to disassemble the Partner 350, several specific tools are required:

  • Clutch key (you can buy or make yourself from the head of the right size).
  • Stop the piston.
  • A set of Torx hexagons.
  • Groove.

Special clutch for clutch

A gourmet for the convenience of disassembling Partner 350 will be needed tweezers and a medical clamp. From ordinary tools, you must have screwdrivers or a battery drill with a set of nozzles, hammer.

Algorithm and description of the disassembly process

If it is necessary to completely disassemble the Partner 350 chainsaw, the first where the disassembly begins, this is the cleaning of the saw using the compressor. Further, the nodes of the chainsaw are removed in the following order:

After the first stage of disassembly is over, we re.clean the chainsaw using the compressor, t. to. There are already access to air ducts, which in most cases are very contaminated with wood dust.

At the next stage, it is convenient to remove the air filter housing and Partner 350 carburetor.

After removing the carburetor, the intake window of the cylinder must be plugged with a rag, this will protect from the entry of foreign objects into the engine crankcase.

The silencer can be removed either immediately after the carburetor is removed, or after the engine is removed. Graduation window is also closed by a rag.

To do this, you need to apply the piston stoppage by installing it in the candle hole.

The clutch on all the Partner 350 chainsaws is unscrewed in the direction of the chain, this is done so that it does not spin during operation. The flywheel nut has a standard thread and is unscrewed with a 13.head, counterclockwise.

After the clutch relief, access to the oil pump appears, it also needs to be removed.

At the last stage, you need to spin the engine screws and remove it from the body.

Instructions for removing a flywheel from the crankshaft

To remove the flywheel, you will need to use a special puller, but most masters use a soft metal gap, t. to. With its help, the removal process is significantly accelerated.

The bottom line lies in the fact that the flywheel nut is removed until the moment is damaged with the plane of the shaft, after which with the help of a hammer and a gap installed on a nut, with a sharp blow, the flywheel is removed from the shaft.

The method is a little barbaric, but time.tested by many masters, as the most practical and reliable.

The need for adjustment

In rare cases, the PARTNER-350 carburetor chainsaw is required, most often there are problems associated with improper fuel input or engine wear. But there are signs that you need to configure the mechanism, here are some of them. After the engine could be launched, he immediately nods. In some cases, users cannot get it at all, and the reason is a lack of fuel or an excess of oxygen. The problem may occur in the event of an increase in fuel consumption, a result of which is an increase in the volume of exhaust gases. This can happen due to the seizure of the mixture by fuel.

HOW TO. husqvarna 55 / 51 ignition coil plug wire replacement

To figure out how the Partner-350 gasoline saw is adjusted, you need to study the design of this node in the first stage as possible in the first stage. Understanding the principles of its functioning and acquaintance with the features of its details will help to identify the cause of the malfunction on its own. Carburetor is one of the main units of the engine. Its purpose consists in the preparation and further supply of the fuel mixture consisting of gasoline and oxygen. In case of violation of the required proportions of these ingredients, the engine begins to function incorrectly, and in the future fails completely.

Mechanical reasons for the refusal

It may require adjustment of the Partner-350 carburetor chainsaw and mechanical failures. For example, due to the effects of strong vibrations, the protective cap may be damaged. In the end, the bolts in the carburetor lose their fixation. The piston part of the engine can also wear out. Carburetor adjustment

In this case, it helps in a certain time to solve the problem, you need to replace the worn part. The cause may be clogging that occurs due to the use of low-quality fuels. Such consequences can lead to damage to the filter and extension of the scale. In this case, the carburetor will need to be disassembled, rinse well and adjust.

Carburetor device

If you decide that the Partner-350 saw is needed, then you first need to study the design of the elements. The system consists of a diffuser, which acts as a narrowing to increase oxygen flow rate. The diffuser is in the immediate vicinity of the input hole through which the fuel is supplied. There is a pipe with a transverse damper in a carburetor, it is necessary to adjust the oxygen flow. Fuel comes from the sprayer, it is represented by a needle. To adjust the fuel at the entrance to the channel, a float chamber is required, it is also available in the carburetor device.

If you purchased the Partner-350 motorcycle, the carburetor adjustment may be needed during operation. In order to perform these actions correctly, it is necessary to familiarize yourself with the principle of operation of this element of equipment. The fuel is sprayed in a diffuser with a stream of air, which allows you to create a mixture pumped into a cylinder. The larger the fuel will come, the higher the engine speeds will be. In the described model, as in any other, the carburetor works on the same scheme described above.

The procedure for checking and setting up proper engine operation

The most vulnerable element of the carburetor engine is the candle. It allows you to judge the probable causes of the malfunction of individual gasoline engine units. The following procedure is recommended.

Dismantle the candle and make it an examination. A dry candle with a light brown shade of electrodes can be considered good.

In the process of installing a new electric module on the engine, you should configure Magneto’s gap. The optimal distance between the flywheel and the ignition coil is for most chainsaws 0.2-0.4 mm.

For fidelity, it is recommended to carefully study the documentation for the purchased model and follow the requirements of the manufacturer.

With such a small gap, it will not be possible to use an affordable measuring tool for direct measurement. In practice, for the Husqvarna saw, a template is used in the form of a gasket carved from thin and flexible sheet material for the necessary thickness. It is clamped in the space between the flywheel and the reel when installing it, and then stretched out.

In order not to resort to ignition adjustment, operate the tool carefully, avoiding shock. In particular, this applies to chainsaws with electronic chips in the ignition system, as they are very sensitive to mechanical damage.

Starter device

Often, manufacturers of chainsaws equip their units with starters working almost according to the same principle, namely: a pen is located in the groove of the saw building, through which the cord is missed. With a sharp raising of the handle, the cord is also stretched, which leads to the clutch of the drum of the ratchet mechanism. Thus, the drum with spitz, which is located on the shaft, is driven into action. At this time, the crankshaft makes several revolutions leading to the compression of the fuel mixture, which at that moment is between the cylinder head and the piston. When lowering the handle, on the contrary, the ratchet and spitz lose their contact, which leads to the stop of the shaft.

With an increase in the power of the chainsaw, the amount of fuel mixture increases, which when the chainsaw is launched should be ignited. In this case, to start the engine, it is necessary to increase the number of jerks of the starter cord. To accelerate the return of the drum mechanism, manufacturers use a special steel return spring of the starter, which has excellent elasticity.

In the case of a breakdown of the spring, it is necessary: ​​to extract the clip of the mechanism, pull out the spring, fixing its upper part with a finger and pulling the starter handle slightly aside. Then, wind a new part, avoiding the bending and twisting of the new spring element, then carefully fix the clip.

Problem: a chainsaw stalls after starting

A common situation: Partner chainsaw stalls at large speeds, although it starts before and works without problems on medium gas. Sometimes on average it also works with interruptions. but it immediately stalls on full gas. This problem is faced with many users who save on high.quality fuel.

Poor.quality gasoline easily pollies the details of the breeder. In this case, checking the filters (air and fuel) will not hurt). over, a muffler suffers from poor fuel and the fuel formed by him.

Dirty fuel combustion products simply clog it, forming an impenetrable cork from Gary. This traffic jam greatly reduces engine power. At the same time, gasoline is consumed in large quantities, but there is no result in power. Check and clean the muffler:

After implementing the recommendations for the elimination of breakdowns, set the muffler in place, season the saw with high.quality (!) fuel and run it.

Partner 350 chainsaw oil. how to choose?

To extend the operating life of the engine and other working mechanisms of the garden tool, it is necessary to use high.quality motor oil for the preparation of the fuel mixture. When burning in the cylinder, it should form as little ash as possible, which settles on the walls of the muffler and on the spark plug.

The engine oil used for refueling should be quickly dissolved in gasoline and be carefully cleaned of harmful impurities, which, over time, settled in narrow channels of the Partner plant carburetor.

Read STIHL chainsaw refueling

In addition, the Partner 350 chainsaw oil should have high lubricants and anti.corrosion properties, and also resist the wear well.

It is best to use for the preparation of fuel mixture of oil for 2-stroke engines of Stihl and Husqvarna brands. They lubricate the operating nodes of the Partner garden tool and, when combined, do not distinguish a large amount of ash.

Determining the localization of a malfunction:

First of all, it is necessary to inspect the candle, if a lot of soot has accumulated on it, then the cause of the malfunction is most likely associated with the work of the carburetor, the piston group or the quality of the fuel. If visually the candle looks good, it does not throw it and it is dry. make sure there is a spark.

How To Install A Spark Plug Boot On Chainsaws, Leaf Blowers, Weed Whackers Etc.

  • Remove the candle, put the ignition cable on it;
  • Using pliers with isolated handles, press the candle thread to the motor body;
  • Sharply pull the starter handle and make sure there is a spark;

If there is no spark, we change the spark plug to a new one and test again. After making sure there is a spark, start the engine. But what to do, even if there is no spark on a good candle? We continue the search:

  • Test an electric cable for a cliff and insufficient contact with the spark plug. We check the serviceability of the spring in the cap of the nursing and the presence of contact with the armored vehicle;

To check the serviceability of the wiring, it is best to use the tester.

You can set the right gap with a probe, they are not a deficit and are available for a small fee.

Graduation channel or muffler cleaning and impact on engine start

During the operation of the chainsaw on the walls of the exhaust channel and muffler, tarry deposits are deposited. Carbon deposits. At times, these carbon deposits must be cleaned, but most of the owners of the tools remember this only after the chainsaw does not start. Why is this happening? Cause

The fact that the food is not fired, because the engine will not be able to start. When the graduation canal is contaminated, the chainsaw not only loses power, and its ignorant engine stops working.

Deposits on the walls of the silencer are justified by subsequent factors:

  • The introduction of poor gasoline and oil
  • Incorrect ratio of gasoline and oil when mixing
  • Long implementation of funds without preventive measures

No problems with cleaning the muffler of the chainsaw. The sequence of cleaning is this:

  • First, unscrew the screws that fasten the muffler
  • The cooling panel with the gasket is dismantled
  • Then it is necessary to remove the spark discharge
  • The resonator case is disassembled
  • All elements are cleaned and washed from carbon deposits with kerosene or other cleansing liquids. This must only be done with the help of a respirator and glasses. Carcinogenic substances are very unsafe for humans
  • Wait for the purified elements dried
  • Collect in the rev for removal.

When cleaning the walls of the output channel, you need to close the cylinder hole with a rag. This will exclude the possibility of dust and sand in the cylinder. After cleaning the silencer and the exhaust channel of the chainsaw, you can start starting the tool motor. With all this, you will feel how the chainsaws work at full power.

Restrictions on independent refinement of a guarantee tool

Even with a light starting system, new equipment that was not launched is relatively close. It is not recommended to dismantle the starter before the expiration of warranty service and repair.

  • For service departments, such an audit may cause a refusal to freely replace more valuable equipment that failed.
  • In the case of independent elimination of minor defects, such as “gasoline is not supplied” or “the air intake is fastening”, no penalties.
  • Practice shows that problems with the launch of a budget chain chainsaw appear after 2-3 years of work. In such a situation, the owner has to put up with additional repair costs or rely on his own locksmith skills.

Thanks to the higher quality of materials and factory assembly, branded models have much fewer problems with the launch. Nevertheless, the recommendations given in this article may be useful for the owners of the middle and high class chainsaws.

The information received will tell you the direction of solving the problem when the Chinese chainsaw will not start. Almost all of the import of the Chinese chainsaw is developed on the basis of European models, so the differences in design and operation are insignificant.

Problem: a chainsaw stalls after starting

Когда бензопила заводится и глохнет, это связано с карбюратором или другими деталями. Causes of malfunction:

  • Fuel does not enter the engine. This is due to the blockage of the saapun.
  • Not enough fuel in the tank. Tilt the tool sideways, the remaining fuel flows to one place. Because of this, the saw stops working.
  • Poor quality fuel.
  • The candle insulator is overheated when poor contact is installed between the cap and candles. The contact between them becomes worse for a halter or a mechanical shift.
  • The spark plugs are faulty.
  • Fuel does not enter the carburetor through the fuel filter or pump. As soon as the tool begins to increase speed, he immediately stalls.
  • If the air filter is contaminated, the engine does not withstand high loads and stops.
  • Not enough or completely absent lubrication in the chain.

If the chainsaw stalls when you press gas, then you need to inspect the gasoline and air filter, as well as the fuel pump.

  • During operation, there is a strong clogging of the air filter, and when you press the gas, the tool stops working. The filter is dismantled, cleaned or washed with warm water, thoroughly dried and only then installed back. Then disconnect the fuel hose screwed to the carburetor. Gasoline should flow through it. The hose is cleaned or replaced by a new one if the liquid does not flow out. The filter is serviceable and it can not be checked if gasoline proceeds well.
  • Gasopile stalls. perhaps the gasoline pump has worn out. If gasoline flows through the walls of the pump, then the device is stalled due to it. This detail is changed to another.

In order for the motorcycle to start, you need to accurately determine the cause of its malfunction, and then try to eliminate it yourself. If the problem is not found or it cannot be eliminated independently, then it is better to seek help from specialists.

Technical characteristics of the chainsaw Partner 371

The Partner 371 chainsaw played not the last role in the very popularity of the chainsaw was played by its good technical parameters. Among them should be highlighted:
