The controller shows E08, and the generator shuts down or refuses to connect to the load.

Safety: Allow the engine to cool. Turn OFF the generator and isolate the battery negative.

• Verify oil level: Use the dipstick to check the oil level. If below minimum, top up with the correct oil grade specified for the Himoinsa engine.
• Inspect for leaks: Check around the sump, oil filter, and oil cooler hoses for signs of leakage. Tighten fittings or replace gaskets as needed.
• Check oil level sensor: Locate the oil level sensor on the sump. Inspect the wiring and connector. Test sensor resistance or switching function according to the engine manual. Replace if faulty.
• Reset alarm: After correcting the oil level and any leaks, clear E08 on the controller and perform a test run. Monitor for recurring alarms, which may indicate excessive oil consumption or internal engine issues.
