The correct ratio of import chain saw mixed oil fuel oil used for 90# (93#), and 2T gasoline engine oil according to volume ratio than the ratio of 20:1, excessive oil will cause difficulty in starting work, Yantai Dalian, too much oil will cause incomplete combustion, soot produced too much, resulting in the engine cylinder, so the ratio of mixed oil should be reasonable, not too much oil is good.
The air filter can filter the chainsaw saw dust, dust and other foreign matter, prevent foreign bodies into the cylinder scuffing cause bad accident. When the chain saw appear flameout, inability to work, gas engine overheating fault, there may be air filter dirty need maintenance. The air filter should be checked before work, qualified clean air filter at the sun light observation should be thorough, bright, the air filter unqualified covered with wood residue, dust, touch feel hard, the air filter with hot soapy water cleaning, dry, clean, transparent, soft, square to ensure the normal work of the chain saw.
Note oil chain saw chain saw chain saw chain oil and wood cutting process, providing lubricating oil and reduce the friction heat of chain saw chain and chain saw guide plate protects the saw bar. Before work, should check whether the chain saw oil filling, boot, saw chain oil should be thrown on the ground out of the oil before work, the lack of chain oil chain saw chain will be high temperature annealing at work, cause the chain saw chain was scrapped prematurely. The specific performance is that the working teeth are easy to dull and are elongated or even broken in a short time.
The normal use of maintenance chain saw guide plate at work to ensure adequate oil chain, at the end of the work to deal with the chain saw guide plate for maintenance. First to clear the root of chain saw guide plate into a hole of debris, and remove the guide groove, an oil inlet hole to ensure smooth. The inside of the guide head should also be checked for foam, dust and other debris, and a small amount of oil is injected into the guide head. When working, should ensure that the chain saw chain sharp, can not saw chain using blunt, but not pressure pressure will cause the saw, saw the working point of the friction plate, chain saw guide plate burnt, degradation, lubrication of chain saws and full chain oil sharp, can improve the service life of the guide. Non reciprocal chain saw guide plate is in use, you can consciously make the flip chain saw guide plate, both sides make full use of chain saw guide plate, can improve the service life of the chain saw guide plate.
Chainsaw saw the use and maintenance of chain saw chain before use, should be in the chain of oil thrown out before working, should soak in the oil bowl after work. In the work process should pay attention to the change of cutting debris, the sawtooth blunt is not sharp, application dedicated file trimming zigzag chain teeth, in order to ensure the correct method of sharp serrated, dressing is: contusion teeth along cutting direction, only toward the tooth direction and teeth, can not be pulled back, angle and file chainsaw chain angle is 30 degrees, the general assembly so that the chain saw chain more blunt, angle is too small, is caused by the chain saw chain is not durable, not sharp chain saw chain will increase the burden on the engine, causing incision burnt and clamping saw, the adverse impact on the chain saw guide plate.
