Chain saws, hand-held saws powered by gasoline engines, are mainly used for logging and lumbering. Its working principle is to cut through the transverse movement of the staggered L-shaped blades on the saw chain. Chain saw is a kind of demolition equipment. According to the function and driving mode, it can be divided into motor chain saw, non-motor chain saw, concrete chain saw, etc. If the working time of the chain saw is too long, it is easy to cause loss, then how should we maintain the chain saw?
Correct use of chain saw
1. Before the chain saw works, let it run at low speed for a few minutes, and watch the chain saw to lubricate the chain oil to the oil line before starting to work. When working, the throttle can be set to use at high speed. After working on a tank of oil, you need to rest for a period of time, roughly 10 minutes. After the work is completed, the heat sink of the lower chain saw needs to be cleaned to ensure the normal heat dissipation of the machine.

2. The air filter of the chain saw needs to be dusted every 25 hours. If you encounter special circumstances, you can deploy it by yourself. The foam filter element can be cleaned with washing liquid or gasoline, and then cleaned with water, squeezed to dry, and then soaked in engine oil, squeezed out the excess engine oil to install.
3. When using a new chain saw, pay attention to the tightness of the saw chain, so that it can push the saw chain to rotate, use a hand-held saw chain, and the guide teeth are parallel to the guide plate. After a few minutes of use, pay attention to observe again and repeat this several times. .
When using a chain saw, make sure that there are no creatures within 20 meters around, and check whether there are hard objects, rocks, etc. on the grass to ensure safety. When the chain saw needs to be left unused, clean the body, drain the mixed fuel, and burn out the fuel in the vaporizer; remove the spark plug, add 1-2ml of two-stroke engine oil to the cylinder, pull the starter 2-3 times, and install it. Put on the spark plug.
The cause of the problem with the chain saw
1. Check the oil circuit and circuit to see if the oil filter is blocked, the carburetor is pumping oil normally, and the spark plug has electricity. Remove the spark plug and place the top on the metal. Pull the machine to see if the spark plug has electricity. of.

2. Remove the air filter and check whether the air filter is clean by the way.
3. Remove the carburetor, and then drop some oil into the cylinder, and then start the machine a few times. If it doesn't, you have to wash the carburetor or replace it, and finally check the cylinder. Teach you a way to maintain the machine. If you do not use the machine for a long time in the future, pour out the oil in the fuel tank. Start the machine to burn out the oil in the carburetor and cylinder. To prevent residual oil from clogging the carburetor, clean the air filter more often. The lubricating oil must be better.
