9. Maintenance
Regular maintenance ensures the longevity and optimal performance of your generator. Refer to the owner's manual for a detailed maintenance schedule.
- Oil Changes: Change the engine oil after the initial break-in period and then according to the recommended intervals.
- Air Filter: Inspect and clean or replace the air filter regularly.
- Spark Plug: Check and replace the spark plug as needed.
- Fuel System: If storing for extended periods, drain the gasoline or use a fuel stabilizer. Propane has a longer shelf life.
- Battery: Keep the battery charged, especially during periods of inactivity. A battery maintainer is recommended.
10. Troubleshooting
If your generator experiences issues, consult the troubleshooting section in your owner's manual. Common issues and their solutions include:
- Generator will not start: Check fuel levels, oil levels, battery connection, and spark plug. Ensure the fuel selector is in the correct position.
- No power output: Check circuit breakers on the control panel and ensure they are in the 'ON' position. Verify all electrical connections.
- Engine runs rough: Inspect the air filter, spark plug, and fuel quality.
For persistent issues, contact DuroMax customer support.
