The transmission system is the key component for chain rotation:
- Clutch: Check whether the clutch spring is broken or worn
- Sprocket: Check the sprocket teeth for excessive wear
- Drive shaft: Check for obvious wear or deformation
3. Check chain status
Problems with the chain itself are also common:
-Tightness: The chain should be able to be easily lifted by hand about 3-5mm
- Wear: Check the chain teeth for excessive wear
- Stuck: Check if there is any foreign object stuck in the chain
4. Lubrication system inspection
Insufficient lubrication can cause the chain to seize:
- Check the fuel tank level
- Check whether the oil line is smooth
- Check whether the oil pump is working properly
3. Preventive measures
According to recent hot topics discussed by users, the key measures to prevent the chainsaw chain from rotating are as follows:
| Precautions | Execution frequency | Effect evaluation |
|---|---|---|
| Clean chains and guides regularly | after each use | Reduce 80% chain stuck problems |
| Maintain proper chain tension | before each use | Extend chain life by 50% |
| Use high quality chain oil | Supplement at any time | Reduce wear and tear by 70% |
| Regularly replace worn parts | every 50 hours | Prevent 95% of transmission failures |
4. Frequently Asked Questions
