How to properly start a Champion chainsaw

How to turn on the chainsaw?

After preparing the tool for sawing and filling the fuel tank, you can proceed directly to starting. It should be remembered that after purchasing a chainsaw, running-in is required. starting at idle, cutting wood (up to 10 cm in diameter) at medium speed. Foreign models reach full capacity after 5-7 tanks are used up, old domestic saws are run in at partial load for 24 hours (3-4 full refills). During this period, it is strictly forbidden to heat the engine, allow continuous idling and give maximum loads when cutting.

Can I start without a starter?

It is impossible to start a chainsaw without a starter. In the absence of this element, there will be disturbances in the engine cooling process, since it contains the so-called “snail, which regulates the flow of cold air from the flywheel impeller to the internal combustion engine cylinder.

Chainsaw and two-stroke engine devices

By design, all models of modern chainsaws are a mechanism that is started by an internal combustion engine. This is usually a single cylinder, two-stroke version that lacks the classic gearbox. Its function is performed by a single-stage chain transmission, which drives the saw headset. The main components of the chainsaw design:

membrane type carburetor;
ignition;
fuel system;
starter;
air purification unit;
chain and bus;
chain brake (contact and inertial);
tension mechanism;
Lubrication system.

Figure 1. External device of the chainsaw

Chainsaws are equipped with a centrifugal clutch that engages automatically depending on the engine speed. With sufficient power, the special elements are pressed against the inside of the drum, setting the drive sprocket in motion. The advantage of such a mechanism is that when the saw jams in the cut, the clutch begins to slip, reducing the risk of breakage of internal mechanisms.

Important! The internal combustion engine in chainsaws has a maximum speed of up to 13.5 thousand per minute. The quality of its work directly depends on the fuel mixture, oil.

Instructions: how to start a chainsaw so that it does not fail prematurely?

Starting your chainsaw correctly is one of the most important steps in using this tool. Sawing productivity, wear of moving parts and overall service life depend on compliance with the rules. When working with any model, it is important to be able to carry out the first launch, diagnose the main problems, and also correctly select and fill the fuel mixture. From the article you will learn how to start a chainsaw and independently check its functionality.

Launch stages

After all the checks, you can run the tool for further work. To do this, place the saw on a stable surface so that the bar does not touch the ground. Step by step algorithm:

Disengage the chain brake using the handle on the chainsaw body.
Turn on the ignition by pressing a button or switch (usually this is the extreme left position).
Move the air damper to the closed position. Pull out the throttle lever, lock it in an intermediate position.
Take the front handle with your left hand, slightly press it to the bottom. Step on the protective shield of the right handle.
With the other free hand, pull the starter handle towards you until the pawls in the ratchet mechanism engage the drum clutch. Make a sharp dash.
After the first flash in the ignition chamber, turn the air damper to its original position. Start saw again.

After the engine starts, give full throttle and fully release the throttle lever. Normally, the trigger block should automatically shut down.

Important! The starting position of the saw depends on the specific model as well as your leading hand. Compact versions of this tool are allowed to be wound by weight.

Winter launch features

Before starting work in winter, it is recommended to first bring the chainsaw into a warm room for 10-15 minutes. If this is not possible, start the tool at idle speed by moving the choke to the middle position. Only increase engine power after preheating. Some models have the ability to switch the air intake in summer and winter mode. this is the optimal solution if you often work in the forest at any time of the year.

How to start a chainsaw?

In most European models, the starting system and starter have a similar device, mechanism of operation. The exception is old domestic chainsaws (Ural, Lesnik). On the body there is a handle through which a cable is passed. If you lift it, the cable engages with the drum of the ratchet mechanism, several revolutions of the crankshaft occur. At the same time, the fuel is ejected and ignited with the help of a candle, after which the chainsaw starts to start. To simplify the start, the following mechanisms can be implemented in high-quality chainsaw models:

installation of a damper in the carburetor for preliminary enrichment of the fuel mixture;
decompression valve, which reduces the working pressure in the engine cylinder;
a spring that, during the movement of the cable, facilitates the unwinding of the crankshaft;
additional pump for pumping fuel (usually found in American manufacturers).

Refueling

It is recommended to prepare the dressing mixture in a metal container. First, pour in the required amount of oil, and then dilute it with gasoline and bring to homogeneity. Carefully pour the prepared composition into the tank of the chainsaw, trying not to stain the body, screw the lid tightly. The finished mixture can be stored for no more than 30 days, after which the oxidation process starts. It is advisable to check the chain oil reservoir at the same time as refueling, refill it if necessary.

How to start a chainsaw: tips and tricks

Novice sawers who do not have the skills to work with chainsaw equipment have to develop their own maintenance skills. How to prepare the fuel mixture and how to start the chainsaw is described in detail in the instructions attached to the tool.

At the initial stage of preparation for the first start-up, the new chainsaw is freed of preservative grease, after which you should make sure that it is complete, securely tightened the threaded fasteners, especially in the area of \ u200b \ u200bthe attachment of the headset, the correct tension of the saw chain.

Reasons for a failed launch

To search for failures characteristic of internal combustion engines, there are developed algorithms that help to detect and eliminate a malfunction with a small investment of working time.

In a simpler version, this is an excess of fuel in the combustion chamber that makes it difficult to ignite the mixture, an unregulated gap in the spark plug, air leakage in the fuel supply system.

Disconnection of the carburetor flap control drive, contamination of the nozzles and the presence of water condensate in the float chamber is also not excluded.

Launch of Chinese-made chainsaws

A significant part of the Chinese chainsaw tools are copies of well-known European brands, while not always successful ones. In order to start a Chinese chainsaw, special skills are not required.

A feature of working with Chinese chainsaws is recommendations for the use of branded engine and chain oils. Leading Chinese manufacturers have developed a wide range of specialty additives that have a positive impact on the performance and durability of Chinese domestic and professional chainsaws.

Preparation and refueling of the combustible mixture

All modern chainsaws, with rare exceptions, are equipped with compact two-stroke internal combustion engines running on high-octane motor gasoline. A metered amount of special engine oil is introduced into the fuel in a ratio of 40: 1 or 50: 1.

There are few requirements for the quality of gasoline. these are:

minimum storage time;
octane number not less than 92;
lack of water and foreign matter.

Fuel system tuning

The factory adjustment of the carburetor is made according to averaged parameters, therefore the necessary adjustments to the operation of the fuel system are made during the operation of the chainsaw.

The sequence of self-tuning the fuel system by the owner himself is given in the instructions. To bring the engine to the fuel and lubricants optimal in terms of thrust and economy of consumption, it is advisable to carry out the adjustment using special equipment, which is equipped with service and repair services.

A running engine is checked for interruptions in the ignition system, extraneous noise, crankcase overheating and other shortcomings. A full lapping of loaded parts and assemblies of a new chainsaw is carried out in an operating mode with moderate loads. With short breaks for engine cooling, you can cut wood with a diameter of 100-150 mm.

Engine oil selection criteria

A full-fledged alternative to the recommended branded oils can be products from leading manufacturers that are similar in performance. As a result of natural selection, Stihl and Husqvarna motor oils and chain oils have been leading in unofficial consumer ratings for many years.

It is strictly forbidden to use cheap analogues of unknown origin for the preparation of a combustible mixture for a chainsaw, as well as motor oils for mopeds and outboard motors.
In order to avoid the risks of acquiring a cheaper, but low-quality counterfeit, it is recommended to buy consumables from branded and licensed trade enterprises.

The working mixture is prepared in a small amount, sufficient to perform a one-time job. For long-term use, more than one month, the combustible composition is not calculated due to significant deterioration in performance.

The mixture is poured through a fine-mesh filter or suede into the gas tank, from which the gas line is fed to the carburetor inlet.

Features of the first and subsequent launches

Learning how to start a chainsaw correctly is, in principle, easy. The necessary skills are acquired directly during operation.

The chainsaw is started with a recoil starter, in most modern models combined with an inertial or spring-loaded system for easy starting. A properly adjusted mechanism reduces the force required to start the engine by almost half.

Since it is impossible to start a chainsaw without a starter, in order to extend its resource, it is necessary to develop a smooth, with a slight acceleration of the cord jerk, which does not create large loads on the design of the starting device.

For the first start, the tool, fueled with fuel and chain oil, should be placed on a level surface, unlocked the accident prevention system and the emergency stop brake of the saw headset. If there is a primer, fuel should be pumped into the carburetor.
To start the engine, set the throttle trigger to low speed and, holding the tool by the handle, pull the starter handle. Starting a chainsaw for the first time, as they say, with a half-turn, most likely will not work. Even a fully serviceable and adjusted tool “grasps” after 3-4 attempts.
At idle, the piston group and the connecting rod-crank assembly operate under oil starvation conditions, so the idling time must be limited to a minimum.

Checking the chain tension

To check the tension of the chain on the saw headset, just pull it with your fingers in the middle of the bar. The link shanks, when properly installed, should not protrude from the grooves by more than a third of the length. The chain should move smoothly along the tire without strong efforts, if the movement is difficult. release the tension.

It is easy to adjust the voltage of this element in chainsaws on your own using a special wing bolt on the body. Some models have two bolts, less often a wrench is required for tightening. carefully read the instructions before using.

What to do if your chainsaw won’t start?

There are many factors why a chainsaw will not start when the starting technology is followed. The most common causes and remedies are:

there is no spark on the spark plug. replacement or drying is required if water gets in;
a problem with the supply of gasoline to the filter. blowing through the fuel hose or filter, replacing;
clogged fuel or air filter. high-quality cleaning is needed.

If these simple tips don’t help, a complete diagnosis of the problem is needed. It is recommended to take the chainsaw to a service center, where they can check the compression of the cylinder and crankcase, as well as the operation of the carburetor.

Starting your chainsaw correctly will ensure that this tool operates smoothly and reliably. At the start, before starting sawing, properly prepare and fill the fuel mixture, adjust the main structural elements. It is important to take into account the weather conditions, as well as the features of a particular model.

Many people buy chainsaws for the first time without having experience with this tool. Despite this, there is no need to take special courses to learn how to use the tool. After the purchase, there is a great desire to quickly test the tool in work. To do this, be sure to first read the instruction manual for the tool, as well as safety precautions when working with a chainsaw. In the material, we will consider how to properly start a chainsaw, as well as work with it.

How to start a chainsaw: starting features

Once the tool is ready to run, you can proceed. The process of starting a chainsaw is as follows:

First, the chain tension is checked. It requires your hand to try to lift the middle chain links at the top of the bar. If the chain stretches with effort, then everything is in order, but if it is easy, then you need to tighten it. Do not overdo it, as excessive chain tension is also highly undesirable.
Checking the chain for constriction. If, after tightening the chain, there are doubts about its tightening, then you can check the correctness by rotating it manually on the tire. The chain should rotate normally without tension.
Installing the hand brake. The hand chain brake is located at the front near the upper handle to hold the tool. If you press the lever forward, then after starting the chain will not rotate, and when returned to the opposite position, the cutting product will begin to move. Before starting, put the tool on the brake.
Fixing the tool on a level surface and starting. To prevent the tool from jerking when starting, you need to grip the upper handle with your left hand, and rest your right foot on the lower handle. The chainsaw is locked, now you can turn on the ignition button, extend the throttle valve, and then pull the starter handle 2 to 5 times. During the twitching of the handle, the engine should give the first flash 2-3 times, indicating that it is possible to push the throttle valve and start. It is necessary to pull the starter handle sharply, and then immediately return it to its original position, without holding it in an extended position.
Removing the hand brake. As soon as the chainsaw starts, let it run for 1 minute without rotating the chain with medium play. The engine will have time to warm up, after which it is necessary to release the handbrake. If a hot engine starts, you can start work immediately after starting.
Checking the oil supply. To do this, you need to bring the file to a sheet of paper and turn it on, after which traces of oil should appear on it.

Having started the chainsaw, you can start sawing wood.

It is important to know! The material describes the process of launching the tool, after which you can start working with it. Do not forget that if you bought a new chainsaw, then you should first run it in.

Chainsaw care

Another important condition for working with the tool is to ensure proper care of it. After completing the work, you should not abandon the chainsaw at the workplace until the next time. It is necessary to clean it of sawdust and debris, periodically check the chain tension, as well as the fullness of the gas tank and oil tank. It is also important to monitor the clogging of the air filter.

It is not recommended to store the chainsaw with filled fuel for a long time, therefore it is better to drain it. It is necessary to replace the chain, tire and drive sprocket in a timely manner, as these are elements that wear out quickly.

In conclusion, it is important to note that over time the chain tends to stretch, which as a result leads to the fact that it cannot be pulled. If you observe such a property, then it is not recommended to continue to operate the tool until the cutting tool breaks at all or comes off the tire. If a person is not confident in his abilities, then it is better not to take up sawing trees of large diameter.

Chainsaw Basics: How to Start a Gas Chainsaw

The starter motor is constantly subjected to dynamic loading. Because of this, it can fail at any time right during launch. With frequent use of the saw, it is recommended to carry out preventive maintenance at least once a year. It is recommended to replace the cord in the starter only with two people, since it is required to securely fix the spring.

How to start a new chainsaw?

Before starting a new chainsaw, you should clean it of the preservative, check the equipment, the reliability of the fasteners tightening, and the chain tension. Before intensive use, the tool must be run in. This should be done not at idle, but at low load, which will avoid rapid engine wear.

The start of the tool is carried out using a starter, which in many models is connected to an inertial or spring-type light start system. With the correct adjustment of this mechanism, the effort that is applied to start the motor is almost halved.

To extend the working life of the starting device, you should work out a smooth movement, in which high loads will not be created.

The first launch is performed in this order:

The equipment should be filled with fuels and lubricants, placed on a flat, stable surface, unlocked the protection mechanism against accidental start and emergency stop.
To start the engine, the throttle lever is set to the low speed position. With a smooth movement, you need to pull the starter, with the other hand. hold the tool. As a rule, a new saw in a technically sound condition starts up from the third. fourth time.
At idle, the crank mechanism operates under conditions of oil shortage, so this time should be minimized.

At the factory, the carburetor is adjusted according to average parameters. Therefore, they are brought to optimal values already during the operation of the chainsaw. The motor should work without interruptions, not emit extraneous noise. For a full lapping of all systems and parts, moderate loads are used.

How to start a chainsaw correctly?

Chainsaws can be started in different ways, depending on the model and technical condition. Today we will look at how to start a chainsaw without a starter, what to do if the tool has not been used for a long time. In any case, before using the tool, you should carefully study the instructions, follow the operation and safety rules.

General rules for using a chainsaw

The basic rules for operating the tool are the same for all brands. Stihl 180, Echo, Ural, and they are as follows:

The saw must be held with both hands, grasping the handle with all fingers.
The employee should not be directly behind the chainsaw, but to the side of it.
Use the top or bottom edge of the tool to cut the material.
If you need to move to another location, for safety reasons, turn off the engine.
You need to start sawing with that part of the bar that is located closer to the body.
The employee must wear special clothing, boots with protective inserts and use personal protective equipment. glasses, durable gloves, a helmet.

How to start the tool after a long period of inactivity?

After long-term storage, you may encounter some problems when starting the motor. The first thing to do is to make sure that the equipment is in good working order, there is a spark, fuel, and there are no wire breaks.

If the saw is in good working order, its launch is in progress:

turn the fuel cock to open;
press the enrichment button, which will fill the carburetor with fuel;
turn the lever and completely close the air damper;
start the engine with the starter. press the throttle stick, pull the cord smoothly, without sudden jerks, turning the crankshaft.
after a flash of a combustible mixture, open the air damper and continue starting the engine.
