18CC Gasoline Petor Chain Saw Mini Chain Saw

1. Chainsaws generally use a mixture of oil, with gasoline grade 90 or above and a general engine oil mixture ratio of 1:25.

2. A chainsaw is a handheld saw powered by a gasoline engine, mainly used for logging and sawing. Its working principle is to use the cross L-shaped blades on the saw chain to perform cutting actions.

3. Mixing of gasoline and engine oil: Mixing ratio: Use a two-stroke engine oil specifically designed for high saw engines, with an engine oil ratio of 1:50, which means adding 50 parts of gasoline to 1 part of engine oil; Using other engine oils that meet the TC level is 1:25, which means adding 25 parts of gasoline to 1 part of the oil. The mixing method is to pour engine oil into a fuel tank that is allowed to be filled with fuel, then fill it with gasoline, and mix evenly.

The mixture of gasoline and engine oil will age, and the general usage amount should not exceed one month. Special attention should be paid to avoiding direct contact between gasoline and skin, and to avoid breathing the gas emitted by gasoline.

1. Regularly check the tension of the saw chain. When checking and adjusting, please turn off the engine and wear protective gloves. The appropriate tension is when the chain is hung under the guide plate and can be pulled by hand.

2. There must always be a little oil splashing out on the chain. Before starting work, it is necessary to check the lubrication of the saw chain and the oil level in the lubrication oil tank. The chain cannot work without lubrication. Working with a dry chain can cause damage to the cutting device.

3. Never use old engine oil. Old engine oil cannot meet lubrication requirements and is not suitable for chain lubrication.
