    Before maintaining the generator, stop the engine. The surrounding condition of the generator is of better ventilation because engine exgaust includes harmful CO. After stopping the generator, clean it immediately to prevent corrosion and remove the sediment.

    • Change lube oil: 20 hours for the first time and 100 hours for the next three times and 200 hours for normal operation. Loosen oi-drained plug located at the bottom of cylinder block when the engine is at hot state. After removing the used lube oil, screw in the plug and add the stipulated oil.
    • Change the air cleaner element: Do not clean the element with the detergent.
    • Change fuel filter: Often clean the fuel filter to ensure that the engine can deliver maximum power. A. Close fuel switch. B. Change the element by loosening the covers of the oil/water separator.
    • Re-checking the bolt re-tightened moment of the cylinder head with a unique tool, shown in the engine manual
    • Check the injector and fuel pump
    • Adjust the clearance of intake 1 exhaust valves
    • Grind the intake/exhaust valves
    • Change piston rings: Need a unique tool and the protection should be paid attention to.
    • Check the electrolytic and charge the accumulator: The 12V accumulation, used in the engine, will consume the electrolytic due to charging and discharging continuously.
