Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start | Old fuel, clogged filter, spark plug issue | Use fresh fuel mix, clean/replace filter, check spark plug |
| Chain won't turn | Chain brake engaged, clutch issue, chain tension too tight | Disengage chain brake, check clutch, adjust chain tension |
| Poor cutting performance | Dull chain, improper filing, insufficient oil | Sharpen chain, check filing angles, fill oil reservoir |
| Excessive vibration | Unbalanced chain, loose components, worn dampeners | Balance chain, tighten components, replace dampeners |
| Chain throws oil | Overfilled oil tank, incorrect oil viscosity | Adjust oil flow, use recommended bar and chain oil |
| Engine stalls under load | Clogged carburetor, fuel line issue, air filter blocked | Clean carburetor, check fuel lines, clean/replace air filter |
Maintenance Schedule
- Before Each Use: Check chain tension, sharpness, and lubrication
- Weekly: Clean air filter, check spark plug, inspect bar for wear
- Monthly: Clean cooling fins, check fuel lines, inspect clutch
- Seasonally: Replace spark plug, clean carburetor, check all safety features
- Annually: Professional tune-up, compression test, complete safety inspection
- Storage: Drain fuel (gas models), clean thoroughly, store in dry location
