Import gasoline saws use maintenance and troubleshooting
In 1, an air filter air filter capable of filtering of chain saw powder dust and other foreign matter, prevent foreign body into the cylinder, causing the piston to bad accident. When the chain saw appear gas flameout, inability to work, engine overheating, there may be an air filter dirty need maintenance. Air filter should be verified before qualified work, clean air filter alignment of the sun light observation, should be thorough, bright, unqualified air filter is covered with wood residue, dust, touch feel hard, this time with hot soapy water wash, dry, clean, transparent, soft, air filter, party can ensure the normal work of chain saw.
In 2, the correct ratio of mixed oil import chainsaw used fuel is 90 # ( 93 # ), gasoline and 2T oil according to volumetric ratio of 20: 1 ratio, too much oil will startup difficulties caused by work, smoke, excessive oil causes incomplete combustion, carbon deposit is excessive, resulting in engine cylinder, so the ratio of mixed oil should be reasonable, not too much oil is good.
3, chain saw oil matters needing attention for the saw chain saw chain oil and wood cutting process, provide lubrication oil and reduce the saw chain and guide plate friction heat, the plate forming protection. Before, should check whether the chain oil filling, after starting up, saw chain oil should be thrown out, on the ground out of oil can be used only for work, lack of chain oil chain saw will be working at high temperature annealing, cause chain saws were scrapped prematurely. As a concrete manifestation of working tooth easy obtuse, short-term inside an elongated, even breaking.
4, the use and maintenance of the saw chain saw chain before use, should be in the chain oil thrown out before work, after work should be soaked in oil bowl. In the working process should pay attention to changes in the sawtooth cutting debris, blunt is not sharp, application dedicated file on the zigzag chain cutting trimming, to ensure that the zigzag sharp, correct trimming method is: along the cutting direction and gear, but towards the tooth direction and tooth, can not be pulled back, and saw file the chain angle of 30 degrees, the angle of the saw chain more blunt, angle is too small, it causes the saw chain is not durable, not sharp saw chain will increase the engine load, the resulting incision burnt, clamping saw, to guide adverse effect.
In 5, the normal use and maintenance guide to ensure adequate chain oil, after work to guide for maintenance. First to clear the debris plate root oil inlet hole, and remove the guide groove, ensure the oil inlet hole patency. The guide head should also check whether the saw dust, dust and other debris, and a small amount of oil in the drip plate head. In the job, should ensure that the saw chain is sharp, can't use blunt saw chain, more incompressible saw, pressure will cause the operating point of the saw guide plate so that the plate friction, burnt, degradation, sharp and full of chain saw chain lubricating oil, can improve the service life of guide plate. The guide plate in use without negative can be conscious, turning plate, the guide plate on both sides to make full use of, can improve the service life of the guide plate.
