Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chainsaw won't start | Dead battery, throttle lock engaged, safety switch issue | Charge battery, disengage throttle lock, check safety switch |
| Poor cutting performance | Dull chain, improper tension, insufficient oil | Sharpen chain, adjust tension, refill oil reservoir |
| Chain won't move | Chain brake engaged, drive sprocket worn, motor issue | Disengage chain brake, inspect sprocket, check motor |
| Excessive vibration | Unbalanced chain, loose components, damaged bar | Balance chain, tighten all fasteners, inspect guide bar |
| Oil leakage | Overfilled reservoir, damaged seals, incorrect oil type | Drain excess oil, replace seals, use recommended oil |
| Battery drains quickly | Old battery, extreme temperatures, excessive load | Replace battery, operate in moderate temps, reduce cutting load |
Maintenance Codes
- Oil Light Flashing: Low oil level - Refill bar and chain oil reservoir
- Battery Light Red: Low battery - Charge battery immediately
- Motor Stuttering: Overload condition - Reduce cutting pressure
- Chain Slipping: Loose chain - Adjust chain tension properly
- Unusual Noise: Worn sprocket or bearing - Inspect and replace components
- Overheating: Continuous heavy use - Allow tool to cool down
