Controller displays “Service Soon” or similar pre-maintenance warning; generator operates normally.

Safety first: Plan maintenance when the generator is not needed for standby operation.

• Review hours: Check the hour meter on the controller to see how close you are to the recommended service interval.
• Schedule service: Arrange for oil, filter, and other routine maintenance before the full “Service Required” alarm occurs.
• Reset (if already serviced): If maintenance was recently completed, reset the service timer in the controller menu according to the manual.

Use this warning as a prompt to prepare parts and schedule downtime for proper maintenance.
