Removing and Replacing the Engine Oil
Tools and Supplies Needed:
10mm Wrench
Rags and approved Container (for waste oil)
Small funnel
Engine Oil (see your Engine Manual for Oil specifications)
Note:
Drain the oil when the Engine is warm; warm oil drains quickly and
completely.
7.
Set the machine on a level surface, place a container between the wheels
under the unit toward the right side, and remove the Oil Fill/Dipstick on the
left side of the machine (
Figure 21
).
8.
On the right side of the engine, use a 10mm Wrench to remove the Oil Drain
Plug allowing the used oil to drain completely through the drain hole into an
approved Waste Oil Container (
Figure 22
).
9.
Replace the Oil Drain Plug, and refill with new oil (see “
Adding Oil and
Gasoline
” on page 11).
Note:
Be sure to use environmentally safe disposal procedures in the disposing of the
used oil.
Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all parts to cool.
Disconnect the Spark Plug Wire, keeping it away from the Spark Plug.
