Chainsaws have long become loyal assistants to summer residents, lumberjacks and tourists. Unfortunately, most cheap models cannot boast of exceptional reliability.
And far from always service centers accept them for warranty repair. And therefore, if you do not start a
chainsaw, do-it-yourself
repairs will save you a lot of money.
What do you need
For work you will need:
- full set of wrenches;
- set of screwdrivers and pliers;
- ordinary sewing needles.
We determine the malfunction
First of all, we find out what exactly happened to the instrument. Most often, chains break , the saws stall shortly after starting, oil runs or the engine does not gain the required power. Of course, you can figure out the chain or the failure of the working bus yourself. But with other points so quickly do not work out.
Checking the gas tank
Be sure to check for gas in the tank. It’s stupid, but sometimes they try to make a saw, in which there is not a drop of gasoline. Very often, the lack of “life” is due to the fact that the breather, which is responsible for equalizing the pressure, completely clogged.
It is easily cleaned with an ordinary sewing needle. After that, you need to clean and dry the candle, blow out the combustion chamber with air. Most likely, a chainsaw, the do-it-yourself repair you just made, will start.
Trigger mechanism
This system must be checked no less carefully. If the starter works fine, there are no delays or excessive lightness when pulling the handle, pay attention to the candle. If there are traces of the fuel mixture on it, then we can talk about a clogged carburetor. It will have to be removed, disassembled and washed. If there is soot on the candle, this indicates poor fuel or poor carb adjustment.
Carrying out the repair of the Ural chainsaw with your own hands, you can try to configure it yourself. But in the case when in your hands there is a more “delicate” imported equipment, it is better to give it to a service center.
Candles and Filters
Never rule out a malfunction of the candle itself. If there is any doubt in it, it is better to put a new one. Be sure to check that the air filter is not clogged.
Piston group
By design, this part of modern saws is not too complicated. It is necessary to unscrew the four bolts that hold the cylinder block, and then remove it. The piston should be carefully inspected. If there is even the slightest damage on it, the part must be changed. The requirements for the cylinder are the same. Carrying out the repair of a chainsaw with your own hands, the ability to squander it is quite small.
Piston rings should fit tightly and should not be damaged. Insert the piston into the cylinder and, holding the top point, try to move it.
If you succeed without much effort, its obvious wear is evident. By the way, precisely because of this, the old engines are not gaining power, and grandfather’s chainsaw, whose do-it-yourself repairs are required almost every day, cannot cope with a cubic meter of firewood.
If there is oil leakage, it makes sense to check the condition of the hose that comes from the oil tank. Unfortunately, to replace it, you will have to almost completely disassemble the entire tool.
Thus, if you do not start a chainsaw, DIY repair is a reality!
