How to use oil of chain saw reasonably

by:Jiali     2020-06-20
The chain saw needs to use gasoline, engine oil and chain saw chain lubricant. 1. For gasoline, only unleaded gasoline above 90 can be used. When adding gasoline, the fuel tank cap and the fuel port must be cleaned before filling to prevent debris from entering the fuel tank. The high-twist saw should be placed in a flat place with the fuel tank cap facing up. When refueling, do not let gasoline spill out, and do not fill the fuel tank too full. After refueling, be sure to tighten the fuel tank cap by hand as much as possible. 2. Only high-quality two-stroke engine oil can be used for the engine oil to ensure a long service life of the engine. Never use an ordinary four-stroke engine. When using other two-stroke engine oil, its model should reach tc grade quality. Poor quality gasoline or oil can damage the engine, seals, oil passages and fuel tank. 3. Mixing ratio of gasoline and engine oil: use two-stroke engine oil for high-twist saw engines for 1:50, that is, 1 part of engine oil plus 50 parts of gasoline; use other engine oils that meet the tc level for 1:25, that is 1 part Add 25 parts of gasoline to the engine oil. The mixing method is to pour the engine oil in a fuel tank that is allowed to be filled with fuel, then pour the gasoline, and mix evenly. The gasoline engine oil mixture will age, and the general configuration amount should not exceed one month of usage. Special attention should be paid to avoid direct contact between gasoline and skin, and to avoid breathing the gas volatile from gasoline. 4. Use high-quality chain saw chain lubricating oil to keep the lubricating oil not lower than the oil level to reduce the 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 hard regulations to this Avoid environmental pollution. Chainsaw repair Inspection steps of chain saw: a: Adjust the oil needle again, tighten the L needle and then loosen it half a turn, and tighten the H needle and then loosen it half a turn. b: Exhaust air, so that oil flows out of the carburetor. c: Pull the fire five or six times, and remove the spark plug to see if there is oil on the machine. d: If there is oil, it proves that there is a problem in the circuit (replace the spark plug, or if it cannot be solved, replace the coil assembly) f: If there is no oil, the oil passage is blocked (check the fuel tank cap, fuel line filter, carburetor for blockage, check valve, pull cylinder, oil seal leak)
