Chainsaws differ slightly in design features, but in most cases, the assembly principle is carried out according to two standard schemes. For many devices, the instructions contain information about the need to activate the emergency brake before starting the start-up procedure. You must first master the device of the plant and study the main ways to correct breakdowns, then a person will have the opportunity to fully operate the device. The article will discuss how to start a chainsaw.
Briefly about the launcher
The chainsaw is powered by an internal combustion engine. This is a simple device, the design of which does not have special frills. Usually it works properly even in difficult conditions.
Functioning is ensured by structural elements:
- Carburetor engine (see carburetor adjustment).
- Clutches of centrifugal type.
- The ignition system, in almost all devices is contactless.
- A carburetor that adds air to the fuel mixture.
- Fuel system. Its standard device consists of a hose, a filter and a gas tank, but sometimes it has additional parts.
- The tire.
- Chain (see chain oil).
- Chain tensioner and chain brake (see how to sharpen a chain).
When the brake is activated, the assembly process is much slower, so everything is also safe and more comfortable you can turn on the mechanism without the use of brake equipment.
If a person is not sure of his knowledge and accuracy, then the brake on the contrary needs to be activated. With the correct sequence of actions, the device will not start, the mechanism will not make actions dangerous to humans.

- Step 1. Before you start the benzoyl, you need to move the damper, which serves as the adjustment lever, to lower it, in comparison with the optimal position. First you need to press the button responsible for the gas supply. Only if this condition is met is the normal movement of the shutter possible to the extreme stop from the bottom. It is necessary to simultaneously move the flap and hold the throttle button. Gas is set to its standard position, and the shutter closes the carburetor, preparing the device for proper operation.
In our rating of chainsaws for quality, you will find all chainsaws with the optimal price-quality ratio.
Another article will help to make your choice in favor of a particular brand of chainsaw.
Chainsaws are of Russian manufacture. low price with a fairly high quality.

- Step 1. The ignition is turned on. To do this, move the toggle switch or move the switch to the desired location.
- Step 2. The swap primer usually has to be pressed more than two times. Gas is poured into it, after which it will be necessary to press the device more than three times. Sometimes a chainsaw is not equipped with a primer, then you can skip this step.

When the device stalls constantly, you need to systematically restart it (see what to do when the chainsaw stalls when you press the gas). After some time, the motor will gain momentum and will be able to maintain active work without interruptions.

If you can not turn on and start the chainsaw
When all actions are performed in accordance with the established procedure, and the chainsaw does not start working, then there are failures in its mechanism. Typically, the cause of this phenomenon is common and easily resolved problems, such as the absence of a spark, blocking the fuel supply, or clogging of the air filter. In order to start a chainsaw, you will have to find the cause and take the necessary steps to eliminate it.
Only correct action should be taken.. If a person does not know what to do, there is no need to commit rash acts. Disassembling the device is prohibited, especially carefully handle the carburetor. You can not unscrew any screws on it, since if its device caused a breakdown, it is impossible to repair a chainsaw without professional equipment.
Lists the actions that need to be performed in a strict order. Only when moving from one event to another can you determine the exact cause of the malfunction and quickly fix it without damaging other details. Algorithm of actions performed in case of failures in the chainsaw institution:
- First, just let the device rest. This is especially true for recently used saws. It is enough to wait no more than 10 minutes, since during this time the mechanism will cool down and, in the absence of other breakdowns, will easily start. Sometimes it happens that during an institution a candle is poured at the device. If this unpleasant property has occurred, then it is enough to wait a very short pause and repeat all the steps again to start the motor.
- The housing cover is unscrewed from the device for removing the air filter. The winding process of the device is carried out in its absence. Sometimes the reason for the lack of ignition is that the filter is dirty. If ignition happened without it, then the reason lies precisely in this. To eliminate these troubles, it is enough to wash the filter under running, warm water and soap, then dry it. You can also replace the old item with a new one.
- The spark plug is removed. A spark check is in progress. If it does not appear, you need to replace the old candle with a new one. Usually this helps and a spark appears, but in some cases there is no spark when replacing the mixture.
This means that the ignition unit is damaged, and the chainsaw needs professional repair. Sometimes there is a malfunction of the ignition unit in the presence of a spark, so this criterion cannot be used to eliminate the likelihood of breakage.
When a spark appears when it is impossible to make the device work, you must continue to perform the steps described below.
For any damage on the cylinder walls, we can conclude that it will have to be repaired by professional methods or replaced with a new one. Typically, such malfunctions result from an insufficient concentration of oil in the fuel.
The chainsaw needs to be started following the standard instructions. If there are any problems with the operation of the device, for example, the chainsaw does not start, you need to quickly fix them or take the device to repair, and to identify malfunctions and work correctly with the chainsaw, you need to know the features of its design. To learn how to quickly turn on the device and correct breakdowns, it is enough to study the main spectrum of necessary actions and follow it.
