How to Fix / Troubleshooting
Safety first: Operate the generator outdoors only. If smoke is heavy, shut down the unit and allow it to cool before inspection.
- Check oil level: Verify that oil is not above the FULL mark on the dipstick. Drain excess oil if overfilled.
- Inspect air filter: Remove the air filter element from the All Power America engine. Clean or replace if dirty or oil-soaked.
- Monitor consumption: Run the generator under load and monitor oil level over several hours. Rapid loss indicates internal engine wear.
- Engine repair: Persistent heavy smoke with high oil consumption requires internal engine service (rings, valves) by a qualified technician.
