Use of oil for chain saws.

Chain saws require gasoline, engine oil and chain saw chain lubricant:
1. Only unleaded gasoline of No. 90 or above can be used for gasoline. When adding gasoline, the fuel tank cap and the area around the filler port 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 up. Don’t let the gasoline spill when refueling, and don’t fill the fuel tank too full. After refueling, be sure to tighten the fuel tank cap tightly by hand.
2. Only use high-quality two-stroke engine oil to ensure a long service life of the engine. Do not use ordinary four-stroke engines. When using other two-stroke engine oils, their models should reach TC grade quality. Poor quality gasoline or oil can damage the engine, seals, oil passages and fuel tank.
3. Mixing of gasoline and engine oil, the mixing ratio: when using the two-stroke engine oil specially used for high branch saw engines, it is 1:50, that is, 1 part of engine oil plus 50 parts of gasoline; when using other engine oil that meets the TC level, it is 1:25, that is, 1 1 part engine oil to 25 parts gasoline. The mixing method is to first pour engine oil into a fuel tank that is allowed to hold fuel, then pour in gasoline and mix evenly. The gasoline engine oil mixture will age, so the general configuration should not exceed one month’s use. Special attention should be paid to avoid direct contact between gasoline and skin and to avoid breathing gases emitted by gasoline.
4. Use high-quality chain saw chain lubricant and keep the lubricant not lower than the oil level to reduce wear of the chain and saw teeth. Since chain saw lubricating oil will be completely discharged into the environment, ordinary lubricating oil is petroleum-based, non-degradable and will pollute the environment. It is recommended to use degradable and environmentally friendly chain saw oil as much as possible. Many developed countries have rigid regulations on this. Avoid environmental pollution.
