    Changing the Engine Oil

    Maintenance Service IntervalMaintenance Procedure
    After the first 5 hours
  • Change the engine oil.
    		•
    Every 50 hours
  • Change the engine oil.Change the engine oil every 25 operating hours when operating the engine under a heavy load.
    		•

    If possible, run the engine for a few minutes before changing the oil because warm oil flows better and carries more contaminants.

    Engine oil capacity0.95 L (32 fl oz)*
    Oil viscosityRefer to Figure 36.
    API service classificationSJ or higher

    *There is residual oil in the crankcase after you drain the oil. Do not pour the entire capacity of oil into the crankcase. Fill the crankcase with oil as directed in the following steps.

    1. Move the machine to a level surface.

    2. Clean the area around the oil-drain nut (Figure 35).

      1. Oil-drain nut

    3. Slide an oil-drain pan under the drain extension and remove the oil-drain nut.

    4. Drain the oil.

      Note: Dispose of the used oil properly at a local recycling center.

    5. Install the oil-drain nut and tighten it securely.

    6. Clean around the oil fill/dipstick.

    7. Unscrew the dipstick and remove it.

    8. Carefully pour about 3/4 of the engine capacity of oil into the oil-fill tube.

      Use Figure 36 to select the best oil viscosity for the outdoor temperature range expected:

      g011606

      Figure 36

    9. Wait 3 minutes for the oil to settle in the engine.

    10. Wipe the dipstick clean with a clean cloth.

    11. Insert the dipstick into the oil-fill tube and screw it in, then remove the dipstick.

    12. Read the oil level on the dipstick.

      • If the oil level on the dipstick is too low, carefully pour a small amount of oil into the oil-fill tube, wait 3 minutes, and repeat steps 10 through 12 until the oil level on the dipstick is correct.

      • If the oil level on the dipstick is too high, drain the excess oil until the oil level on the dipstick is correct.

      Important: If the oil level in the engine is too low or too high and you run the engine, you may damage the engine.

    13. Install the dipstick into the oil-fill tube securely.
