Running in a chainsaw and other Stihl tools

Stihl chainsaw running in

The days of the first chainsaws (“Ural” and “Druzhba”) in our country are over. The times have passed with them when questions such as “How to run in a chainsaw” were topical. Stihl does not require running-in. Absolutely! No. Even if you are told to test it by uncles in the market where you buy it.

By the way, if you buy a Stihl tool on the market, it means 99.99999% that you are buying not Stihl, but its Chinese replica. Firstly, this tool is sold only at official points of sale, through the manufacturer’s website and a few sites of certified partners. Secondly, not a single company manager will tell you that you need to do a cold start and run in a Stihl chainsaw. Why? Let’s take a closer look below.

How to run in stihl gas powered tools

The chainsaw came off the conveyor and was delivered to the workshop, where it was assembled, filled with oil and a fuel mixture, checked, turned on and. were fixed in a special running-in chamber of the gasoline-powered tool, which is located there, at the factory, next to the conveyor. During the specified time, it goes through a “hot” run-in until the components and mechanisms are completely lapped to each other. in fact, this is the purpose of running-in and the best way to run a Stihl chainsaw. Therefore, as soon as you purchase it, refuel and fill in oil. and immediately into battle! Work for 10-15 minutes, rest for 5 minutes, then 15-30 minutes, and rest again. After 3-5 tanks of gasoline, it will pick up maximum power, and it will be possible to work according to the data sheet time.

In addition, according to the analogy just described, you cannot run in a Stihl brushcutter, or a Stihl brush cutter, or even a Stihl trimmer. Yes, other manufacturers may recommend such a run-in, but in this case, with Stihl, it will only be a waste of time and your resources (effort, fuel, oil).

If you want to run in a Stihl tool (whether it is running in a Stihl gas cutter, running in a Stihl asphalt cutter or something else), we can only recommend running in for grinding in parts that you changed after a planned replacement or as a result of repairs. For example, in a lawn mower, such a replacement could be subject to:

  • cutting nozzles;
  • body;
  • engine belt or wheel drive belt;
  • the shaft on which the knives are attached;
  • motor.

How do you run in a Stihl lawnmower in this case? Give it a gentle work for 30-60 minutes, get rid of especially tough stems of grass and debris, which usually leads to damage.

How to run in a Stihl blower

The blower is also called a garden vacuum cleaner. This is a very handy tool that in a matter of minutes can get rid of light debris and fallen leaves, because a garden plot (usually 30-50 sq.m.). Like other Stihl tools, it is factory run-in as required, so there is no need for additional run-in. Only in the first days of work, give him a reduced load, you cannot immediately let him “into battle” at 100%.

For grinding in household tools, it is enough to slightly increase the amount of oil in the fuel mixture. Chainsaws made in China, like other tools, need to be run in, and it is carried out in the same way.

Correct actions during the first four hours of operation are the key to reliable operation of the chainsaw for the entire service life.

Running in a chainsaw engine after repair

If you figure it out, the parts installed during the repair, like the parts of a new tool, are run-in during the same period of time, which means that the conditions that contribute to this must be the same. This means that for a successful run-in of the engine after a major overhaul, the following steps must be performed:

  • Enrich the air-fuel mixture by unscrewing the screw H by ¼ from the position at which the maximum engine speed is reached, and for chainsaws that do not have the ability to adjust the carburetor, increase the amount of oil in the mixture with gasoline.
  • Allow the engine to cool more often.
  • After working for the first 4 hours, dilute the fuel mixture for household models of the tool according to the manufacturer’s instructions, and for models with carburetor adjustment, bring the maximum engine speed, by adjusting the H screw, to normal.

Chainsaw break-in. everyone gets it wrong!

After reading on the Internet tips on how to properly run a chainsaw, many begin to spoil their device, significantly reducing its service life.

Fortunately for the owners and especially those who give harmful advice. the damage caused by improper running is not immediately noticeable, since it is very difficult to spoil a new device at once.

Therefore, in appearance everything is fine, and breakdowns and repairs will happen later, everything will be blamed on marriage, bad gasoline or manufacturer’s shortcomings. Do not repeat other people’s mistakes! However, about everything in order.

How is this possible?

If the manufacturer “forgot” to indicate in the instructions information about the initial running-in, then the “fault” may be several considerations:

  • 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 on the surfaces of moving parts is such that no amount of “running-in” in domestic conditions by handicraft methods can change anything. But adding soot to the exhaust system is quite.
  • The concept of “selective assembly” will soon exist for a century. 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.

How to break in a new chainsaw?

Running in a new chainsaw is just as important as taking care of your tool. Even a beginner can follow this simple procedure. We will talk in more detail about what running-in is needed for, and how to perform it correctly.

Criteria for self-selection of motor and chain oils

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

Instructions on how to properly run in a new or refurbished chainsaw

A hand-held chainsaw can be a great help for woodworking. At the same time, not many people know that the first hours of operation of the unit require the implementation of certain rules for running in. Chainsaw break-in is a process necessary for both a new and a tool after a major overhaul.

Beginners who have never had experience with a chainsaw need to approach this process responsibly.

It should be noted that even if an incompetent seller claims an optional running-in procedure for the saw, it is still recommended that you familiarize yourself with the instructions attached to it and this article before the first start.

Chainsaw break-in. we 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 simply assembling the saw without the saw 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 that can only be given by the cutting chain.

In this case, it is possible not only to “develop” the motor, but in general to get used to the location of the tool handles, its ergonomics, which, although created for one thing. for comfort, but differs from different manufacturers.

Preparatory stage

The repair of any equipment should begin with the preparatory work, and the calm saw 180 is no exception. At the preparatory stage, before the calm 180 chainsaw is disassembled, it is necessary to remove the side cover, chain and tire from the chainsaw. Further, using a compressor and a brush, you need to clean the chainsaw from dirt, sawdust, oil drips and other things.

When cleaning the saw, pay special attention to the place where the chain saw drive sprocket is located, since this is the most polluted area.

In places with a large accumulation of oil, can be washed with clean gasoline.

Removing the starter

At the next stage, the upper case cover is removed and the 4 starter mounting screws are loosened, after which it is necessary to remove the oil tank and fuel barrel covers. The starter is removed quite simply and there should be no problems.

BEST way to Break in a New Chain Saw

After removing the starter, the opened inner cavity of the chainsaw must be cleaned, since usually there is a large amount of compressed small sawdust on the body under the starter.

Removing and disassembling the engine

The engine is held in place by 4 screws installed on the bottom of the Stihl 180 chainsaw. To remove them, unscrew them, then carefully remove the engine from the seat and the rubber pipe of the carburetor.

To disassemble the engine, 4 crankcase screws are unscrewed, and it is removed, then you can remove the crankshaft assembly with oil seals, bearings and piston rings.

Removing bearings and seals usually does not require additional tools, but if the bearings were pressed onto the shaft with force, then a special puller will be needed for dismantling.

To remove the piston from the connecting rod, you will need to remove the retaining ring from the seat using a thin screwdriver, then the piston pin is squeezed out from the opposite side, after which the piston is retracted to the side.

Disassembly and assembly Calm MC 180

Stihl MS 180 is a reliable and unpretentious tool, but sometimes it requires repair, like any technique. In this article, we will consider how the disassembly of the chainsaw calm ms 180 takes place, which is necessary in the event of an engine overhaul.

Carburetor, muffler and ignition coil

To remove the carburetor, you must have a head 8 and an extension, with which it is convenient to unscrew the nuts securing the carburetor and air filter. Before dismantling the carburetor, it is necessary to disconnect the ignition wire and the choke rod from the engine control lever and remove the lever, only after that the air filter and carburetor are removed.

The Stihl 180 muffler is attached with two nuts, by unscrewing which you need to pull it towards you, it can be easily removed.

The coil is mounted on two screws, to remove you just need to unscrew them.

Removing the handle

The direct disassembly of the calm 180 begins with the removal of the handle, which is attached to the body of the chainsaw using three rubber shock absorbers. To remove, it is necessary to remove the plastic plugs from the inner cavity of the shock absorbers, then, using a powerful screwdriver, first squeeze out the upper shock absorber, then the one closer to the rear handle.

At the back of the handle there is a throttle trigger, which is connected to the carburetor through a wire rod, in order to disconnect the throttle trigger from the throttle trigger, it is necessary to unscrew two screws and disassemble the handle.

When the handle remains on one shock absorber, it is necessary to unscrew the body of the chainsaw from the inside of the handle and bend it to the side, remove the body from the last rubber band.

Removing the flywheel

The flywheel of the Stihl 180 chainsaw is twisted with great effort, therefore, to remove it, you will need a head with a metal knob. The nut holding the flywheel is unscrewed by the head by 13.

To block the crankshaft from turning, you need to unscrew the spark plug and install the piston stopper through the spark plug hole, if it is not there, you can use the old cord from the starter, with knots tied to it and immersed in the cylinder through the spark plug hole.

It is strictly forbidden to keep the flywheel from turning by installing a power screwdriver and other tools between its ribs and the body, with this method of blocking from turning, the flywheel blades are not able to withstand the load and break off.


After the piston is locked in the cylinder, you can unscrew the flywheel nut. The thread in the nut is ordinary, so you need to turn it to the left. Having loosened the nut, you do not need to remove it to the end, it is enough to unscrew it until its upper edge is equal to the tip of the shaft, after which a soft metal drift is installed on the nut and a sharp blow is made on it. Thus, the flywheel from a sharp impact jumps off the shaft and can be easily removed without the help of additional tools.
