Engine Oil

Engine lubrication is essential and must be maintained to ensure long engine life. It is extremely important to use proper type and weight of oil in the crankcase. It is also extremely important to check oil daily and change it regularly as outlined in the maintenance schedule.

See Engine Operator’s Manual for a detailed description of engine oil maintenance. Also the Engine Operator’s Manual provides additional information necessary to keep the engine in top operating condition. Follow all maintenance procedures provided in the Engine Operator’s Manual.

NOTE: Running engine low on oil can cause engine damage and void engine warranty.

NOTE: Overfilling of oil level can cause loss of power, engine damage and void engine warranty.

  • Check oil level daily before starting engine.

  • Make first oil change after the first month of operation or at 20 hours of operation (whichever comes first).
