Precautions for the use of oil saws
1. Check the chain tension regularly
When checking and adjusting, please turn off the engine and put on protective gloves. The proper tension is when the chain is hanging under the guide plate, you can pull the chain by hand.
2. There must always be a little oil spill on the chain
Always check the oil level of the saw chain lubrication and lubricating oil box before working. The chain cannot work without lubrication. If it is operated with a dry chain, the cutting device will be damaged.
Never use old oil
Old engine oil can not meet the lubrication requirements, not for chain lubrication.
4. If the oil level in the oil tank is not lowered, it may be the fault of lubrication transmission

The chain should be checked for lubrication, oil circuit.
Contamination through the filter can also lead to poor supply of lubricating oil, which should be cleaned or replaced in the oil tank and pump connection pipe.

5. After replacing and installing the new chain, it takes 2 to 3 minutes for the chain to run in
Check the chain tension after grinding. If necessary, adjust it again. The new chain needs to be tensioned more frequently than the one that has been used for some time.
When the working temperature is reached, the chain expansion saws sag slightly, and the transmission link below the guide plate cannot get out of the chain slot, otherwise the chain will change jobs, and the chain needs to be re-tensioned.
6. The chain must be relaxed after work
Chains will shrink as they cool, and unloosened chains will damage crankshaft and bearings.
If the chain is tensioned at work, it will shrink as it cools and damage the crankshaft and bearings.
