How to match the oil in the chain saw, what is the ratio of engine oil to gasoline, and what kind of engine oil is better.

1, chain saws generally use mixed oil, gasoline is more than 90%, and the general mixed oil ratio is 1:25.

2. The chainsaw is a portable saw powered by gasoline engine, which is mainly used for logging and wood making. Its working principle is that the staggered L-shaped blades on the saw chain move laterally to play a shearing role.

3. Mixing of gasoline and engine oil: mixing ratio: two-stroke special for high-powered saw engine is used, and the engine oil is 1: 50, that is, 1 part engine oil and 50 parts gasoline; Other engine oils meeting tc grade are 1∶25, namely 1 engine oil and 25 parts gasoline. The mixing method is to pour the engine oil into the fuel tank which is allowed to contain fuel, then pour the gasoline and mix well.

Gasoline and engine oil will age when mixed, and the general configuration should not exceed one month's usage. Pay special attention to avoid direct contact between gasoline and skin, and avoid inhaling the gas volatilized from gasoline.

Matters needing attention in using chainsaw

1. Be sure to check the tension of the saw chain. When checking and adjusting, please turn off the engine and wear protective gloves. The appropriate tension is that when the chain is hung on the lower part of the guide plate, it can be zipped by hand.

2. There will always be a little oil spill on the chain. Always check the lubrication of saw chain and the oil level of lubricating oil tank before work. Without lubrication, the chain can never run. If it works with the dry chain, the cutting device will be damaged.

3. If the oil level in the oil tank does not drop, it may be that the lubrication transportation is out of order. Check the chain lubrication and oil circuit. Passing through the polluted filter screen will also lead to poor supply of lubricating oil. The lubricating oil filter in the connecting pipe between the oil tank and the pump should be cleaned or replaced.

4. Never use old engine oil. Old engine oil can not meet the lubrication requirements and is not suitable for chain lubrication.

5. After replacing and installing a new chain, it takes 2 to 3 minutes for the saw chain to run in. Check the chain tension after running-in, and readjust if necessary. New chains need to be tightened more frequently than those that have been used for a while. When cooling, the saw chain must stick to the lower part of the guide plate, but it can be moved on the upper guide plate by hand. If necessary, tighten the chain again. When the working temperature is reached, the saw chain will slightly expand and sag, and the transmission joint at the lower part of the guide plate cannot be separated from the chain groove, otherwise the chain will jump off the ship and need to be re-tensioned.
