Chainsaw, as a common garden machinery tool, is mainly used for felling diseased trees, old trees and tree shaping and pruning. Its correct maintenance is essential to extend service life, improve work efficiency and ensure safety. The following will introduce the maintenance and maintenance methods of chain saws in detail:

Daily cleaning: After each use, the dirt, dust and oil on the surface of the chain saw need to be cleaned to ensure that the machine is clean and tidy. Clean the air filter regularly to prevent impurities from entering the cylinder and avoid causing cylinder pull and other faults.

Fuel management: Check the amount of fuel in the fuel tank before use to ensure that there is enough fuel for use. When storing for a long time, drain the fuel in the fuel tank and carburetor to prevent oil blockage.

Engine maintenance: Change the engine oil regularly to keep the engine clean and lubricated. Check the spark plug, remove carbon deposits, and clean it. Clean the crankcase, crankshaft and connecting rod to check for wear or damage.

Transmission mechanism maintenance: The reducer should be filled with sufficient lubricating oil to ensure its normal operation. Check the flywheel, cylinder sleeve, piston top, muffler and other parts, remove the dirt and check for abnormalities.

Maintenance of sawing mechanism: Remove the saw chain guide and saw chain, clean and apply a thin layer of anti-rust grease. Check the tension of the saw chain to ensure that it can mesh correctly when the machine is cold.

Maintenance of chain and guide: Check the tension of the saw chain frequently and adjust it when necessary. Use high-quality lubricating oil to keep the saw chain and guide lubricated to prevent damage caused by dry running. Sharpen the saw teeth regularly and trim them along the direction of the saw teeth to ensure sharpness.

Long-term storage: When not in use for a long time, the chain saw should be sealed and placed in a ventilated and dry place. Remove the spark plug, add an appropriate amount of engine oil to the cylinder, and pull the starter several times.
