The controller shows 'Maintenance Due', 'Service Soon', or a similar reminder; the generator still operates normally.

Safety first: Turn OFF the generator and disconnect the battery negative terminal before performing maintenance.

Steps:

• Perform scheduled service: Change engine oil and oil filter, replace the air filter and spark plugs, and inspect the fuel system per the Honeywell maintenance schedule.
• General inspection: Check the battery, cables, enclosure, and wiring for corrosion or damage.
• Reset maintenance timer: Use the controller interface to reset the maintenance interval according to the manual.
• Test run: After service, run a manual test to verify proper operation.
