Changing the Engine Oil

Service Interval
After the first 2 hours yearly.
Run the engine a few minutes before changing the
oil to warm it. Warm oil flows better and carries more
contaminants.
1. Ensure that the fuel tank is not overfilled and that the
fuel cap is securely in place.
2. Move the machine to a level surface.
3. Place an oil drain pan under the oil drain plug
(refer to page 2­17), remove the oil drain plug, and tip
the machine backward (handle down) halfway to the
ground to drain the used oil into the oil drain pan.
IMPORTANT
Do not tip the machine all the way back to the ground, or
fuel may leak out of the machine.
4. After draining the used oil, return the machine to the
operating position.
5. Install the oil drain plug and tighten it securely.
6. Clean around the oil fill cap.
7. Unscrew the oil fill cap and remove it.
8. Slowly pour oil into the oil fill hole. Wait 3 minutes,
then check the oil level on the dipstick by wiping the
dipstick clean and then inserting, but not screwing in,
the oil fill cap into the hole.
NOTE
To determine the proper oil level on the dipstick, refer
to Fig. 002.
