How to repair and maintain the chain saw chain

23 September 2021

Chain saw chain repair:

1. If the chain saw is refueling and stalling, working less vigorously, or the heating machine is overheated, it is usually a filter problem. Therefore, the filter should be inspected before work. A clean and qualified filter should be pierced and bright for observation under the sunlight, otherwise it is unqualified. When the filter of the chain saw is not clean enough, it should be washed with hot soapy water and dried. Only a clean filter can ensure the normal use of the chain saw.

2. When the saw teeth of the chain saw become unsharp, you can use a special file to adjust the teeth of the saw tooth chain to ensure the sharpness of the saw teeth. At this time, it should be noted that when using a file to frustrate, you must frustrate in the direction of the cutting tooth, not the other way around. At the same time, the angle between the file and the chain of the chain saw should not be too large, preferably 30 degrees.

3. Before using the chain saw, you should add the chain oil of the chain saw. The advantage of this is that it can provide lubrication for the chain saw, reduce the friction heat between the chain saw chain and the chain saw guide plate, and protect the guide plate. It can also protect the chain saw chain to avoid premature scrapping.

4. After the chain saw is used, the chain saw should also be maintained, so that the working efficiency can be guaranteed when the chain saw is used next time. The first is to remove impurities in the oil inlet hole and the guide plate groove at the root of the chain saw guide plate to ensure the smoothness of the oil inlet hole. Secondly, clear the sundries in the guide plate head and add a few drops of engine oil.

Use and maintenance of chain saw:

Oil distribution for chainsaw:

The chain saw is a two-stroke power, and attention should be paid to power, cutting tools, etc., to ensure the normal use of the machine: the engine is a two-stroke engine, the fuel used is a mixture of gasoline and engine oil, and the ratio of the mixed oil is: air-cooled two Special-stroke engine oil JASO FC grade: gasoline=1:50 (air-cooled two-stroke special engine oil JASO FB grade: gasoline=1:25).

The gasoline should be above No. 90, and the engine oil should be air-cooled two-stroke engine oil, the symbol is 2T, and brand-name special engine oil must be used. Four-stroke engine oil or water-cooled two-stroke engine oil is strictly prohibited. It is recommended that the new machine be equipped with 1:40 (JASO FB grade engine oil 1:20) in the first 30 hours, and the normal ratio of 1:50 (JASO FB grade engine oil 1:25) after 30 hours. It is strongly not allowed to exceed 1:50 ( Ordinary engine oil 1:25), otherwise the concentration is too thin will cause the machine to pull the cylinder.

Please dispense oil strictly according to the oil dispenser attached to the machine, not arbitrarily dispense oil according to estimates. The mixed oil is best prepared for immediate use, and it is strictly forbidden to use the mixed oil that has been used for a long time; before the machine works, run it at low speed for a few minutes, see the lubricating chain oil, form an oil line, and then work. When the machine is working, place the throttle on the high speed use. After each tank of oil work, you should rest for 10 minutes. Clean the loose gasket of the machine after each work to ensure heat dissipation; the spark plug should be removed every 25 hours of use, and the dust on the electrode should be brushed with a wire, and the electrode gap should be adjusted to 0.6 -0.7mm is better; the air filter removes dust every 25 hours of use, and the dust should be more frequent. The foam filter element is cleaned with gasoline or washing liquid and clean water, squeezed to dry, and then soaked in oil, squeezed out the excess oil to install.

Every 50 hours of use of the muffler, remove the muffler and clean up the carbon deposits on the exhaust port and the muffler outlet. The fuel filter (suction head) removes impurities every 25 hours.

When using the new machine of the cutter part, pay attention to the tightness of the saw chain, so as to push the saw chain to rotate. It is advisable to use a hand-held saw chain with the guide teeth parallel to the guide plate. After a few minutes of use, pay attention to tensioning the saw chain again.

Before using the safe operation, no people or animals are allowed to move around within 20 meters. Be sure to check whether there are angle irons, stones and other debris on the grass, and remove the debris on the grass.
