How to properly break in a chainsaw

Correct running-in of the chainsaw is the key to further trouble-free operation. It is important to strictly follow the instructions of the instrument manufacturer. There are advice of this type that you need to run in a new chainsaw at idle until the tank is full. It is not right. Idling is harmful to the tool because:

  • Not enough lubricant is supplied to moving parts;
  • Operation without optimal load causes increased wear of friction pairs.

It is better to use a gentle mode of operation, which combines several tens of seconds of idling and spraying of thin logs (10-15 cm) from soft wood. In this mode, the running-in occurs with the highest quality.

How To Properly Run A New Chainsaw

The engine acquires the declared technical characteristics after running out of several fuel tanks. During this time, do not overload and overheat the tool.

Preparing for the first launch

  • Correctly prepared fuel mixture;
  • The presence of oil in the saw chain lubrication system;
  • Serviceability of the air filter;
  • Correct chain tension;
  • Correct operation of the emergency chain brake.

Some gasoline tool manufacturers require a different ratio of oil to gasoline in the fuel mixture. If this is not directly stated in the instructions, then the mixture must be prepared as for permanent work, Using high-octane gasoline (no worse than 92 and 95 brands) and special oil for two-stroke high-speed engines.

The parts of the saw chain teeth that move in the grooves on the guide bar must be lubricated to reduce friction and wear on the saw attachment. Use special chain oil.

It is imperative to lubricate the driven guide bar sprocket with liquid oil through the technological holes at the end of the bar.

It is important to correctly tension the chain. An overly tensioned chain puts a lot of stress on the engine and friction mechanism and is subject to wear. The chain tension is checked by pulling the chain away from the bar. The chain guide teeth must NOT protrude completely from the bar grooves.

First start

When everything is ready to start, you can try starting the engine:

  • The ignition switch is moved to the working position.
  • If there is a primer in the carburetor, press the button until the fuel mixture enters there.
  • Place the saw on a level surface so that the chain does NOT touch the ground.
  • With the left hand on the handle, the dust is pressed down.
  • With the right foot, step on the inside of the protective shield of the operating handle.
  • Close the air damper completely.
  • Smoothly pull the starter handle up until the play in the Khrapov mechanism is selected, and then pull it sharply, turning the engine crankshaft.
  • After signs of ignition appear (pops in the cylinder), open the air damper and try to start dust.

Starting your chainsaw for the first time may take some time to start with the air damper closed, especially in cold weather.

Do I need to run in and why

The chainsaw is run in for the reason that new or replaced parts require an exact fit to each other. It is not possible to produce all the components with the required high precision. It takes some time to burn in the surface roughness of cylinders, piston rings, friction units.

During the running-in period, stabilization and alignment of the necessary clearances, backlash in pairs of engagement and friction occurs.

The main rules for running a saw headset and a chainsaw engine

The newly acquired tool, like the one that was repaired, differs in that individual parts have roughness, manufacturing tolerances. As the running-in progresses, increased wear occurs in some areas, and then most of the inconsistencies are smoothed out, and the wear operation is suspended. This process of controlled wear is called tool break-in.

A non-rolled tool, operating at maximum load, has increased and uncontrolled wear, which leads to a reduction in service life. Timely and correctly performed running-in of the chainsaw contributes to the rapid acquisition of the declared technical characteristics by the tool.

Engine break-in

Engine break-in is the main process of preparing a gasoline tool for constant load.

After running-in, it may be necessary to readjust the carburetor. In the absence of experience, this work must be PROVIDED to the service center, since an incorrectly adjusted carburetor can lead to a quick engine failure.

Running in the saw headset

Running in a new chain or bar does not require as much attention as an engine. The main task of running-in is to evenly distribute the lubricant between the chain links and lapping the moving joints of the links. Contrary to popular belief that running in the chain and drive sprocket is necessary, this is not necessary. A saw that has been running on one chain for a long time already has a run on the drive sprocket, and no running-in will be able to fully match the new chain and the old sprocket to each other.

Running in a new chainsaw or a new guide bar, with its simplicity, requires care and accuracy. The budget segment tool of little-known manufacturers is prone to identify problems during the break-in process.

How to break-in a new chainsaw correctly?

Before you start running in your garden tool, you need to make sure that the carburetor settings required for operation are set on it. To do this, you need to study the instruction manual, which indicates the correct position of the screws. If it does NOT correspond to the position of the screws on the chainsaw, then you will need to Unscrew them yourself.

After that, you will need to carefully inspect the chainsaw device and make sure there is an air filter. some models go on sale without it. Then you need to prepare a fresh fuel mixture and add oil to lubricate the chain.

Next, you need to do the following:

  • First, the tool must be equipped with a standard saw bar, on which a break-in chain for a chainsaw must be installed. Using this part instead of a standard headset will help to use all the moving elements of the saw, avoiding increased stress on them;
  • Next, you need to start the engine of the tool and let it run at idle. The duration of the engine operation in this mode must be at least 20 minutes. In this case, every 45 seconds, the operator must gas the engine;
  • After 20 minutes, the engine will need to be turned off. After that, you need to wait for the engine to cool down and start it again;
  • Then the operator must start sawing small branches. You need to continue spraying until the fuel used is used up;
  • After that, you need to fill the dust with fresh fuel and start sawing branches of medium thickness. As soon as the second tank with fuel is used up, you need to drown out the dust and let the engine cool down;
  • When the saw has cooled down, you will need to refill with new fuel mixture and start sawing large wood.

On average, running in a new chainsaw takes at least 2-3 hours. During this time, the parts will have time to finally get used to each other and establish stable operation for further intensive operation.

Do I need to run in a chainsaw?

A gasoline chain saw consists of a number of units, which, during intensive work, lend themselves to heat and increased friction. As a result of heavy use, most garden tool parts are subject to severe wear. Most often this leads to minor breakdowns, however, there are often cases in which deformation of the drive sprocket occurs, the formation of burrs on the surface of the cylinder-piston group and other serious breakdowns.

To avoid THESE malfunctions and to establish the proper operation of all elements of the chainsaw, after purchasing it, you will need to run in the household tool. In the process of its implementation, the moving parts are displaced in the direction required by the unit device. In addition, running in a new chainsaw allows the used lubricating fluids to be evenly distributed throughout the tool structure and to cover the saw parts with a thin oil film. In the future, it will protect the chainsaw mechanisms from high temperatures, increased friction, corrosion and carbon deposits.

How to break-in a new chainsaw correctly?

Like any other garden tool, a gasoline saw needs careful preparation for use. This allows its owner to reduce the load on the engine and other important components of the unit during the first days of operation after purchase, as well as prevent premature breakdowns associated with increased friction of operating mechanisms.

Running in a Chinese chainsaw. procedure

The main difference between most of the chainsaws from China from the equipment of European and American brands is their high power. Because of this, Chinese gardening tools need a longer break-in period.

Before starting the preparation of a Chinese chainsaw, its owner must be convinced of the correctly set carburetor settings. If the adjustment was not made by the manufacturer, then the settings will need to be set. over, experienced users do NOT recommend that beginners do the first carburetor adjustment on their own. It is best to attribute the dust to a service whose employees specialize in the maintenance and repair of chainsaws from China.

Further running-in of the Chinese garden tool is performed in the following sequence:

  • The operator must first prime the tool with a mixture of fuel and chain oil. At the same time, one must remember the principles of fuel preparation. Chinese saws need more engine oil than European ones;
  • After that, you need to start the saw engine and leave it to idle until the first tank with fuel is completely depleted. In this case, every minute you need to run the motor;
  • Then you need to refuel the chainsaw and start sawing small dry branches. It is necessary to work with wood with minimal loads on the engine’s internal combustion engine and turns off the engine to cool down every 15 minutes;
  • As soon as the second tank of fuel is used up, you need to fill in a fresh fuel mixture and start processing the wood of medium thickness. Sawing small branches and logs is necessary in the development of the third fuel tank;
  • After that, you will need to wait for the engine to cool completely and refuel the chainsaw to cut large logs.

The main requirement when running in a new Chinese chainsaw is to take breaks when the plastic body of the tool heats up to a critical state. This indicates an EXTREME speed of rotation of the crankshaft, which can lead to a violation of its fixation and breakdown of the engine’s CPG.

How to extend the life of a new headset?

Experienced sawfillers practice daily exposure of a new saw headset in a container with hot chain oil at a temperature not painful 60 ° C.

This procedure, known as the stabilization of the internal structure of the metal, has a positive effect on its resistance to external stress and temperature influences. Identical technology is recommended for cutting saw sets used as replacement equipment.

During the running-in process, it is necessary to periodically check the chain tension, the presence of chain oil in the reservoir and its supply to the cutting area. It is better to postpone the testing of the emergency stop mechanism until the development of certain working skills.

Fuel preparation features

Each chainsaw differs from the same type of model, design features, dosage of the fuel-oil working mixture, therefore, even with proper experience, it is recommended to familiarize yourself with the attached operating instructions.

For the preparation of fuel, it is advised to use fresh gasoline with an octane number of at least 90 and a heat-resistant engine oil recommended by the manufacturer, in the dosage indicated in the instructions.

The fuel mixture in an amount sufficient for one-time operation is prepared in a fireproof metal container, in the best version with a hermetic stopper. In the absence of oils recommended by the manufacturer, replacement with a full-fledged analogue of the JASOFB or ISOEGB category is possible.

Gasoline with oil components should not be stored for more than 2 months. The performance of an overexposed gasoline / oil mixture degrades significantly over time.

How to properly break in a chainsaw

The resource of new chainsaw equipment largely depends on the quality of its preparation for subsequent operation. How to properly run a European or Chinese-made chainsaw with maximum efficiency?

The low-cost in time and material investment process of running in a new tool has a positive effect on its performance and duration of use.

Moderate loads during the first stage of running-in contribute to a full-fledged lapping of internal parts, a complete and inexpensive development of the assigned overhaul and operational life.

Factory run-in benefits

It should be noted that new saws from many leading manufacturers do NOT need running-in. The running-in of the piston group and working equipment using a special technology is carried out directly in the process of control tests.

The chrome plating of the inner diameter of the cylinder and the application of wear-resistant coatings on the working surfaces of loaded parts helps to reduce the time of this stage. However, the sparing recommendations for the first hours of tool operation remain valid.

Preparing for the first launch

Before starting the chainsaw, make sure that the emergency stop mechanism of the headset is turned off. The engine is started in the sequence recommended by the instructions.

After a short warm-up, the power unit is recommended to be brought to medium speed to check the lubrication system. To do this, just hold the typeface over the letter of the paper. The presence of an oil strip indicates that the system is working and that the saw chain is fully lubricated.

Sprocket bearings on guide rails 16 inches or more are individually lubricated after 8-10 hours of operation.

Recommendations for the training stage

  • The practice of running in a new chainsaw without a saw headset is fundamentally wrong, since all its moving elements need to be run in.
  • The typical run-in time is several hours. In any case, the design of chainsaws of any quality and price level does NOT provide for prolonged engine operation at idle.
  • In this mode, the loaded parts of the piston group and the connecting rod-crank mechanism experience a significant lack of lubrication, which inevitably leads to overheating and forced wear of the working surfaces.
  • The total running-in time at idle speed with periodic blow-by of 25-30 seconds should not exceed 15-20 minutes.

The operation of the engine being run in without load at high speeds is strictly excluded. over, idling running in the tool is ineffective; the best result can be obtained when exposed to moderate loads. The new chainsaw can be used for sawing medium-density wood with small diameters up to 100 mm.

Carburetor adjustment

A full running-in of a new chainsaw provides for the correct setting of the fuel system. The standard factory adjustment of the carburetor is based on averaged data, therefore, depending on external factors, it needs to be adjusted.

The saw with the carburetor adjusted should pick up speed quickly, equally stable at operating mode and idle. The brown color of the spark plug insulator also shows the proper quality of the air / fuel mixture.

Criteria for self-selection of motor and chain oils

The composition of the engine and chain oils recommended by the manufacturer contains special additives that provide working surfaces with full lubrication in a wide range of operating temperatures.

Preparation for operation of chainsaws made in China

The standard running-in of a Chinese chainsaw requires the use of only branded engine oils designed to meet the performance characteristics of the Chinese chainsaw range.

Most powerful Chinese models run on motor and chain oils with special additives, which have a positive effect on the stability of their working and performance characteristics.

How to properly break in a new chainsaw?

Many who bought a new chainsaw are concerned about the question. How to run it in. After all, the parts must be rubbed against each other before working at full capacity. Well, let’s analyze this issue in this article so that it does not torment you anymore. These rules are suitable for chainsaws of any company. even Stihl, even Husqvarna, or any Chinese. At the same time, everything is so simple that it is not necessary to watch any. just read it. Also, these rules can be applied in the case of replacing the piston on a used chainsaw.

They looked into the instructions?

In general, when buying a new chainsaw, it would be nice to look at its instructions. Did you do it? If not, then look into it and look for a break-in point. If you have one, then just follow this guide and you will be happy. As a rule, in such a paragraph it is indicated that the mixture needs to be made more enriched, and the maximum speed should also be reduced. This is achieved by rotating the corresponding screws. Such rules are given, for example, by Husqvarna for its professional range of chainsaws.

But still it seems to me that there is a running-in point in your instructions, which is why you are looking for advice on the Internet. Well, indeed, there are a large number of chainsaws where there is not a word about running in the manual. This mainly applies to household appliances. Or the information is so sparse that nothing is clear. What to do in this case?

Running in at idle speed? STOP.

The first thing that comes to mind is to start the chainsaw in the old fashioned way and leave it to idle until the gasoline in the tank runs out. I want to warn you right away that you shouldn’t do this. This is what the old Friendship and the Urals did. On modern chainsaws, this trick leads to overheating, because of which your unit, if it does NOT break down immediately, then its resource will significantly decrease. Overheating occurs due to the fact that at idle, little air enters the cylinder from outside. And it serves not only to ensure the ignition of the fuel mixture, but also to cool.

You will say: “There is a radiator” Yes, but for ease of use (so that there is less weight and dimensions) it is made small, so it simply will not have time to cool.

Well, how to run-in?

“And what remains to be done?”. you ask. Let’s use the tips, which are still written in the instructions for some chainsaws. The Stihl company cites such a running-in rule to all its chainsaws (taken on the official website here in the instructions for the MS 170 and MS 180 models, page 35, but it is also written in the instructions for any other Stihl chainsaws):

That is, all that Stihl requires from the user of a new chainsaw is not to give high engine speed, if you are NOT going to give a load at the same time. Simply put, if the gas, then be sure to saw something at this time. That’s all! But in general, we all give full speed just at the moment when we are going to make a cut. And why bother just gas? Therefore, it is unlikely that you can make a mistake here.

Also, in the instructions for some Chinese chainsaws, they write that the user must add a little more oil to the fuel mixture than it should be in normal mode, until the chainsaw develops 3-4 tanks of fuel. That is, for example, if you want to dilute gasoline with oil in a ratio of 1:40, then the first three to four tanks should be diluted in a ratio of 1:30.

Thus, it seems that the implementation of these two simple rules will be a necessary and sufficient condition when running in a new chainsaw, as well as a used one, in which the piston was replaced.

That’s all there is to know on this matter. Follow these rules and your chainsaw will serve you to the maximum.

That’s all there is to know on this matter. Follow these rules and your chainsaw will serve you to the maximum.

Preparing a new product

It is necessary to install a frame and chain on the tool. There are often tips on the net to make the first starts without load, but they are extremely harmful and will lead to the opposite result. Lack of load has a detrimental effect on the condition of the new engine:

  • Fuel combustion mode changes;
  • There is no possibility of uniform lubrication of all surfaces;
  • The quality of heat dissipation decreases.

All these factors contribute to the formation of carbon deposits, the formation of scoring, which can lead to seizure of the piston. A major overhaul of a new chainsaw will be required, which could have been avoided, correctly Run in.

Figure 1. Running in a chainsaw

Before starting the direct work, some preparation will be required. It is no less important for obtaining a successful result, therefore, we will consider the process in stages:

Do I need to run in a chainsaw?

A new or overhauled chainsaw is not ready for full load. It is necessary to operate it for some time in a softer mode, so that all moving parts properly rub against each other. This applies not only to the piston group of the engine, but also to the elements of the cutterbar and frame. The gentle mode allows you to prepare the mechanisms for full load, reduce or completely eliminate the risk of pistons jamming in the cylinder, facilitate the chain movement without unnecessary friction and heating.

The main problem with non-rolled chainsaws is the lack of uniform transfer of heat energy to the cylinder walls. It remains on the piston, which expands and creates the threat of wedging, which means engine failure and the need for overhaul. When all the smallest irregularities and roughness are smoothed out, there is a good contact of the piston with the cylinder, which increases compression and heat transfer. This evens out the operating mode and removes unnecessary frictional loads. In addition, the noise level is reduced, which is also important for users performing large volumes of work.

Features of running-in tools from different manufacturers

Chainsaws from different manufacturers differ from each other in design, engine power and other parameters. Accordingly, the process of running in them also takes place taking into account the specific features of the tool. It should be taken into account that top manufacturers supply the market with fully prepared tools, and not requiring running-in. Information about the operating modes, the need for running in and other fundamental points can be found in the instructions for this chainsaw.

Basically, running-in is required for domestic and Chinese chainsaws. It is produced in accordance with the rules set out and specific methods set out in the instructions.

Consider the nuances of performing the procedure for two popular models of chainsaws:

  • STIHL MS-180 (Stihl). German chainsaws, known all over the world. The carburetor for THESE instruments is shipped commercially set to the tool run-in mode. The fuel-oil mixture is made up in a ratio of 1:50; for a complete break-in, at least 5 full tanks will be required. It is strictly prohibited to start and leave dust to work on the canvas! It has air cooling, which practically does NOT function in this mode.

For normal cooling, a flywheel operation is necessary, and this is possible only under a load, even a small one. After the end of the running-in, you should contact the service center to reconfigure the carburetor to the operating mode.

  • CHAMPION (Champion). Chinese tools are difficult to repair and should be handled with great care. Break-in of Champion chainsaws is carried out on a fuel-oil mixture with a ratio of 1:50. It is necessary to use the oil of the same brand name. CHAMPION JASO FD, since Chinese tools are sensitive to the quality of fuels and lubricants. The manufacturer requires 6-8 full fuel tanks to be run-in to run-outs. There are special requirements, except for normal conditions. soft mode of operation without prolonged loads at full engine speed.

Figure 4. Running in the chainsaw “Champion”

Types of running-in

There are two types of running in:

  • Factory. Produced at the tool manufacturer. Many modern models of chainsaws undergo full factory training and do NOT need additional running-in. You can work with them at full capacity right from the moment of purchase;
  • Household. Run-in by the owner of the saw. Produced in the first days after purchase or after a major overhaul.

Factory run-in is carried out by specialists in conditions close to ideal. This guarantees a positive result and high quality running in. At the same time, the household running-in of the chainsaw will in any case be carried out after the engine overhaul. Therefore, it is necessary for every owner of the instrument to be able to produce it correctly.

Checking the lubrication

The lubrication check should not only be done during running-in. This is a permanent procedure that must be followed throughout the life of your chainsaw. The following elements need to be checked:

  • Oil level in the reservoir;
  • The condition of the saw frame lubrication channels;
  • The presence of grease on the drive sprocket, in particular on the needle bearing;
  • Sprocket driven state.

According to the results of the inspection, the channels should be cleaned, applied to the driven sprocket with lithol or grease.

How to run-in a new technique correctly. Step by step instructions

After completing all the preparatory procedures, they proceed to direct running in. Procedure:

  • Disengage the brake on the cutting tool (move the handle forward until it contacts the front handle). This is a mandatory procedure, otherwise strong heating will occur in the clutch area, which can lead to melting of the body and failure of the instrument parts. The condition of the chain is checked by pulling it in the direction of travel. Hands must be wearing gloves.
  • Close the choke and turn on the ignition. If there is a decompression valve, turn it on.
  • Grasp the starter handle, pull it a little until a tight contact is formed and jerk it with a sharp movement several times until fuel flashes in the combustion chamber. The saw should start and stall in a second or two. After that, the air damper is opened and the engine is restarted.
  • After starting, gas is carried out to full engine speed, after which the dust is left to idle for 3-5 minutes. on how to start your chainsaw.
  • Spray small trunks or branches with a thickness of NOT more than 10 cm.The load is dosed. first small, then medium, and the transition to the maximum working load is made at the end of the running-in (after running out of 5-6 full fuel tanks).

After the end of the run-in, it is necessary to adjust the carburetor to the operating mode.

Fuel-oil mixture production

The type of fuel most suitable for a given brand of tool is always indicated in the instructions. For running-in, you will need a mixture of gasoline and oil, prepared in a proportion determined by the manufacturer. As a rule, gasoline with a minimum octane rating of 90 is used. For Russian fuels, A92 or AI92 brands are relevant. Higher values ​​should not be chosen, as they are often faked.

The optimal choice of oil is synthetics, it completely burns out. Usually the oil is 2% (1:50), but for some models of Chinese chainsaws this value changes (1:25), and for Partner tools. 1:40. It is necessary to use the ready-made mixture as early as possible, ideally on the same day, but not later than several weeks. During the running-in process, you will need to develop 5-6 full tanks of the mixture.

How to properly run a chainsaw. detailed instructions and recommendations.

Any gas powered tool needs competent operation to ensure maximum performance in combination with optimal loads on the engine and other tool components. A chainsaw, as a cutting tool operating in difficult and hazardous conditions, needs to comply with operational requirements to the greatest extent. One of the most important conditions for correct work is to create optimal working conditions in the first days of tool operation.

Running a chainsaw is an important and crucial stage of operation, which requires an understanding of the meaning and purpose of all procedures performed. The question is important and requires detailed coverage.

  • Do I need to run in a chainsaw?
  • Types of running-in
  • Preparing a new product
  • Fuel-oil mixture production
  • Checking the lubrication
  • Carburetor adjustment
  • How to run-in a new technique correctly. Step by step instructions
  • Features of running-in tools from different manufacturers
  • What are the threats and ways to overcome them

Carburetor adjustment

Most manufacturers pre-set the carburetor to run-in mode, so adjustments are only required to establish normal operating conditions at full load. The purpose of the procedure is:

  • Fuel supply adjustment in optimal mode;
  • Stabilization of engine operation;
  • Getting maximum engine power;
  • Elimination of smoke and claps during tool operation.

Figure 3. Setting up the carburetor

The carburetor has special adjusting screws, the location of which must be specified in the instructions. With their help, idle speed, maximum and minimum engine speeds are set. The adjustment is carried out with the chain installed, since in the process it will be necessary to control the moment it starts to move. The setup process does not present significant complexity, but for the first time it is recommended to involve a competent and experienced specialist who can control the correctness of actions.

Preparing for the first launch

Before starting the chainsaw, make sure that the emergency stop mechanism of the headset is turned off. The engine is started in the sequence recommended by the instructions.

After a short warm-up, the power unit is recommended to be brought to medium speed to check the lubrication system. To do this, just hold the typeface over the letter of the paper. The presence of an oil strip indicates that the system is working and that the saw chain is fully lubricated.

Sprocket bearings on guide rails 16 inches or more are individually lubricated after 8-10 hours of operation.

Let’s consider all the upcoming process step by step:

  • A ready-made fuel mixture, in which, as you already guessed, there will be not only gasoline, but also oil (usually 2-stroke, like engines).

Regarding the latter, it is important to understand that the best advisor, who can help you choose it accurately, is the instruction to the saw itself, which indicates not only the brand, but also the proportions of the mixture itself, which are strictly prohibited.
Pour chain oil into the grease tank.

If the oil indication is not possible, and the running-in is not a new one, but a tool restored after repair, you can check yourself whether the device is filled with grease. To do this, bring a blank sheet of paper to the tire and start. If there is oil, there is always a greasy mark.

If you miss this point, it may turn out that when the engine goes to maximum speed, the tire and the chain will immediately fail, because. The frictional force will prove to be an instant destructive factor.
Starting a “cold start”, it is worth detailing the information from the instructions, in which, usually, this is also covered.

  • Do not look at the importance of the inertial brake, it is still recommended to turn it off when running in, then the chain and tire will be able to smoothly sag and stretch. Otherwise, plastic parts may overheat and start Not only melting, but also creating a fire hazard.
  • One of the most fundamental rules, which is also worth winding up on a mustache, as they say, is the time factor. For this case It must not be less than 4 hours.

    We hope that after this there will not be even a hint of the question of whether it is necessary to run in the chainsaw, because everything is already obvious. Care and Respect. and the minimum gratitude that everyone is able to give their petrol assistant for his service.

    Recommendations for the training stage

    At the initial stage of running the chainsaw, adhere to the following rules:

    • Bar and chain should always be lubricated with special saw lubricant;
    • It is forbidden to roll in dust entirely at idle, because when the engine is running, oil should flow to the sawing parts of the chainsaw, but this does not happen in idle;
    • When the first 5-7 hours have been worked out, Drain the remaining fuel mixture from the chainsaw and mix with a fresh mixture;
    • Try NOT to overload the tool during the first 4-5 refuelings, work in moderate mode, also refrain from sawing logs with a diameter of more than 40 cm.

    Enough has been said about what a chainsaw is for and what requirements a modern gasoline tool must meet.

    But besides, in order to choose one modification out of a thousand that would best meet consumer needs and just like the use, it is important to understand what operating conditions are required for this particular device, so that it justifies the investment and lasts as long as possible.

    In addition to caring for the body, the oil pump and the cutting set, a very important point concerns the running-in of a new chainsaw. a manipulation that must take place before the fruitful operation of this device begins. And what it is for and how it is done correctly, we will discuss in this article.

    Chainsaw break-in. Recommendations and features of running in chainsaws

    The running-in process for a chainsaw is very important. it is on it that the quality of the running-in of key parts of the chainsaw engine depends, as well as the further operation of the tool in various conditions.

    For the correct running of a new chainsaw, the owner needs to remember a few fundamental points:

    • Running-in is NOT the same for saws from different manufacturers;
    • Chainsaws of various production differ in engine brands, percentage of the fuel mixture, which means they need a unique run-in;
    • It is important to establish at what stroke the chainsaw is run-in. cyclic or idle (this information must be indicated in the instructions, which must be read before starting work with the chainsaw).

    An example is the Husqvarna chainsaw. its break-in is always done only on a cyclic stroke! In this case, the engine must operate at high speeds, but with low power.

    How to properly break in a new chainsaw. instructions for beginners

    Before you start running the chainsaw, a number of preparatory procedures should be carried out. First, it is necessary to prepare and pour the fuel mixture into one of the tank tools.

    In this case, you must strictly observe the proportions specified in the manual for the chainsaw. Then a break-in chain is installed on the tire, and oil is poured into the second tank to lubricate it.

    The procedure for running in is as follows:

    • Start the chainsaw engine according to the manufacturer’s instructions and let it idle for 20 seconds
    • After that, lightly press the throttle lever and let the chainsaw run at minimum loads. this takes about 90 seconds
    • Move the tool over the paper and make sure the oil is flowing to the saw chain. This will cause small drops of oil to appear on the paper;
    • Start sawing thin branches and twigs;
    • Replace the break-in chain and check the fuel and oil level in the chainsaw tanks;
    • Move on to sawing medium to large branches.

    It is possible that after running in, you will need to adjust the carburetor of the chainsaw. You can find out about this in the recommendations specified by the manufacturer in the instruction manual for the chainsaw. After completing all the above steps, you can start sawing branches and logs of medium and large thickness.

    Chainsaw break-in. Observe the correct sequence

    When the technical details contained in the user manual are already sufficiently studied and understood, you can proceed to this process directly.

    It is important to know that just collecting dust without an intent mechanism and trying to start it will not give any sense. the tool should feel the load from the first seconds of being in your hands, which can only be given by the cutting chain.

    At the same time, it is impossible not only to “develop” the motor, but in general to get used to the arrangement of the tool handles, its ergonomics, which, although created for one thing. for comfort, but differs in different manufacturers.

    The nuances of running a Chinese chainsaw

    Chinese chainsaws, in essence, are the same tools that have a two-stroke engine with an air cooling system.

    This means that running in the engine and models of Chinese-made tools is carried out using the creation of identical conditions as for tools assembled or in Europe. I would like to note that the products of the well-known brand Stihl, and in particular the MS 180 chainsaw, have been produced by a Chinese plant for a long time, although the German brand.

    As a rule, all models of Chinese chainsaws are equipped with carburetor adjusting screws, respectively, at the time of running-in, let’s limit the maximum number of engine revolutions, thereby enriching the fuel mixture.

    Let’s also increase the percentage of oil in the fuel mixture during the break-in period.

    How is this possible?

    If the manufacturer “forgot” to indicate information about the initial running-in in the instructions, then there may be several reasons for this:

    • He has a fairly good technological base, which allows high-quality manufacturing of the surfaces of cylinders and liners.
    • The degree of hardness and the ability to withstand wear of the surfaces of moving parts is such that no amount of “running-in” in domestic conditions using a handicraft method can change anything. But adding carbon deposits to the exhaust system is quite.
    • The concept of “selective assembly” will soon exist soon. When the tolerances of parts are matched to each other in such a way as to provide the Highest accuracy class of fit, even using NOT infinitely accurate and expensive equipment. Friction surfaces in an internal combustion engine are the most critical component. Increased demands are usually made on him, so everything is initially accurate.

    In addition, this does NOT mean at all that such an operation is absent in production. It is known for certain that some manufacturers perform “cold” running-in. without engine operation, in a special lubricant environment. But this has nothing to do with the consumer.
