Because the chainsaw is a two-stroke drive, it is a mixture of oil, and many of the beginners are using the oil saws, such as the cylinder, etc., mostly because the oil is not mixed well, and even forgot to mix with the two-stroke engine oil!
The chainsaw is a two-stroke power, which should be paid attention to in the use of power, cutting tool and so on, so as to ensure the normal use of the machine.
Today, we will mainly talk about the maintenance knowledge before and after the use of the chainsaw.
1. Use safety.
No one or animal is allowed to move around within 20 meters before the operation.

The engine is a two-stroke engine with fuel oil mixed with oil, and the mixture ratio is: two-stroke special engine oil: gasoline = 1:50 (general motor oil: gasoline = 1:25).
The gasoline is used above 90, and the oil is used for two stroke oil, the symbol is 2T, must use the famous brand special oil, the use of four-stroke engine oil is strictly prohibited.
Suggestions, new in the top 30 hours with 1:40 (ordinary oil 1:20), according to normal after 30 hours (normal oil 1:25) oil distribution proportion 1:50, resolute don't allow more than 1:50 (normal oil 25), or concentration is too thin will cause machine cylinder.

After each case of oil, take a 10-minute break, clean up the machine after each work, to ensure the heat dissipation;
The spark plug should be removed every 25 hours, and the dust on the electrode should be brushed with wire brush, and the gap between the electrodes should be adjusted to 0.6-0.7mm.
Air filters remove dust every 25 hours and dust should be more frequent.
