Warning for using a chain saw
1. Check the tension of the saw chain frequently, turn off the engine and wear protective gloves when checking and adjusting. The proper tension is when the chain is hung on the lower part of the guide, the chain can be pulled by hand.
2. A little oil must always be spilled from the chain. Always check the chain lubrication and the oil level of the lubricating oil tank before work. The chain must not work without lubrication, such as working with a dry chain, it will cause damage to the cutting device.
3. If the oil level in the oil tank does not decrease, the lubrication delivery may be malfunctioning. The chain lubrication should be checked and the oil circuit should be checked. Passing through a contaminated filter can also cause poor lubricating oil supply. Clean or replace the lubricating oil filter in the pipeline connecting the oil tank and the pump.
4. Never use old engine oil. Old engine oil cannot meet the lubrication requirements and is not suitable for chain lubrication.
5. After replacing and installing a new chain, the saw chain needs 2 to 3 minutes of running-in time. Check the chain tension after running-in and readjust if necessary. New chains require more frequent tensioning than chains that have been used for a while. The saw chain must be close to the lower part of the guide plate when it is cold, but the saw chain can be moved on the upper guide plate by hand. If necessary, re-tension the chain. When the operating temperature is reached, the saw chain swells and sags slightly, and the transmission link at the lower part of the guide plate cannot escape from the chain groove, otherwise the chain will jump and the chain needs to be re-tensioned.
