Gasoline chain saw is abbreviated as chain saw. It is generally used for forest harvesting, timber production, branching, etc. as well as timber storage timber production, railway sleeper saw cutting and other operations. The sawing mechanism is a saw chain, and the power part is a gasoline engine. It is convenient to carry and easy to operate, but maintenance and repair are more complicated. If the chain saw appears to be fueling and flameout, it does not work so hard, and the heating machine overheats, it means that the chain saw is broken. Afterburner will give you a detailed introduction on how to repair the chain saw when it fails, let's take a look! 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. If you have not finished your work, you need to rest for a period of about 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. 4. If the oil saw is turned off, the work is not so strong, the heating machine is overheated, etc., it is generally the problem of the filter. Therefore, before working, the filter needs to be inspected. The clean and qualified filter should be observed through the sunlight and should be thorough and bright, otherwise it is unqualified. When the filter of the chain saw is not clean enough, it should be washed and dried with hot soapy water. A clean filter can ensure the normal use of the chain saw. 5. When the saw teeth of the chain saw become unsharp, you can use a special file to rest the cutting teeth of the saw chain to ensure the sharpness of the saw teeth. At this time, it should be noted that when using a file, it should be set in the direction of the cutting tooth, and it should not be reversed. At the same time, the angle between the file and the chain saw chain should not be too large, preferably 30°. 6. The chain saw oil should be added before using the chain saw. The advantage of this is that it can provide lubrication for the chain saw, reduce the frictional heat of the chain saw and the guide plate of the chain saw, and protect the guide plate. The chain saw chain can also be protected from premature scrapping. 7. After the chain saw is used, the chain saw should be maintained so that the work efficiency can be guaranteed when the chain saw is used next time. The first is to remove impurities in the oil inlet hole and guide plate groove of the root of the chain saw to ensure the smoothness of the oil inlet hole. Secondly, the debris should also be cleared in the head of the guide, and a few drops of oil should be added.
