1. The gasoline can only use unleaded gasoline of No. 90 or above. When adding gasoline, the fuel tank cap and the surrounding area of the fuel filler opening must be cleaned before refueling to prevent debris from entering the fuel tank. The high branch saw should be placed on a flat place with the fuel tank cap facing upwards. Don't let gasoline spill out when refueling, and don't overfill the fuel tank. After refueling, be sure to tighten the fuel tank cap as hard as you can by hand.
2. The oil can only use high-quality two-stroke engine oil to ensure that the engine has a long service life. Do not use ordinary four-stroke engines. When using other two-stroke engine oils, the model should be of tc grade quality. Poor quality gasoline or oil can damage the engine, seals, oil passages and fuel tank.
3. The mixture of gasoline and engine oil, the mixing ratio: use the special two-stroke engine oil for the high branch saw engine to be 1:50, that is, 1 part of oil plus 50 parts of gasoline; use other engine oil that meets the tc level is 1:25, that is, 1 25 parts of gasoline to 25 parts of engine oil. The mixing method is to first pour the oil into a fuel tank that allows fuel, then pour the gasoline, and mix it evenly. The gasoline-oil mixture will age, and the general configuration should not exceed one month's use. Special attention should be paid to avoid direct contact between gasoline and skin, and avoid breathing the gas volatile from gasoline.
4. Use high-quality chain saw chain lubricating oil, and keep the lubricating oil not lower than the oil level to reduce the wear of the chain and sawtooth. Since the chain saw lubricant will be completely discharged into the environment, ordinary lubricants are petroleum-based, non-degradable, and will pollute the environment. It is recommended to use degradable chain saw oil as much as possible. Many developed countries have rigid regulations to prevent Avoid environmental pollution.
