Removing and Replacing the Engine Oil
Tools and Supplies Needed:

1/4" Allen Wrench

Rags and approved Container (for waste oil)

Engine Oil (see your Engine Manual for Oil specifications)
Note: Drain the oil when the Engine is warm; warm oil drains quickly and
completely.

under the front of the unit between the wheels.
1. Remove the Oil Drain Plug at the front of the Engine using a 1/4" Allen
Wrench allowing the used oil to drain completely through the drain hole and
down into the Container (
Figure 12 ).
2. Replace the Oil Drain Plug and refill with new oil through the Oil
Fill/Dipstick ( Figure 13 ). See “ Adding Oil and Gasoline ” on page 10.
Note: Be sure to use environmentally safe disposal procedures in the disposing of the
used oil.
