Chainsaws, portable saws powered by gasoline engines, are mainly used for logging and timber production. Their working principle is to rely on the lateral movement of the L-shaped blades on the saw chain to perform the cutting action. Chain saw is a kind of demolition equipment. According to the function and driving method, it can be divided into motorized chain saw, non-motorized chain saw, concrete chain saw and so on. If the working time of the chain saw is too long, it is easy to cause wear and tear, how should we maintain the chain saw?
The correct use of chain saw
1. Before the chain saw works, let it run for a few minutes at low speed, see the chain saw lubricating the saw chain oil and weigh an oil line before starting work. When working, the throttle can be set to use at high speed. Every time you finish a box of oil, you need to rest for a period of time, roughly 10 minutes. After the work is completed, the heat sink of the chain saw must be cleaned to ensure the normal heat dissipation of the machine.
2. The air filter of the chain saw needs to be dedusted once every 25 hours. If it encounters special circumstances, it can be adjusted by itself. The foam filter can be cleaned with washing liquid or gasoline, and then washed with clean water again, squeezed to dry, then soaked with engine oil, squeezed to remove excess engine oil can be installed.
3. When using the new chain saw, please pay attention to the tightness of the saw chain, in order to drive the saw chain to rotate, use the hand saw chain, the guide teeth are parallel to the guide plate, after a few minutes of use, pay attention to observe again, so repeat several times .
When using a chain saw, make sure that there are no creatures within 20 meters of the surrounding area. Check whether there are hard objects or stones on the grass to ensure safety. When the chain saw needs to be left unused, clean the body, release the mixed fuel, and burn the fuel in the carburetor; remove the spark plug, add 1-2ml of two-stroke engine oil to the cylinder, pull the starter 2-3 times, install Put on the spark plug.
