How To Change The Engine Oil
Used oil is a hazardous waste product and must be disposed
of properly. Do not discard with household waste. Check with
your local authorities, service center, or dealer for safe dis-
posal/recycling facilities.
1. Place bricks or wooden blocks under the front wheels to
lower the rear of the engine.
2. Loosen or remove the oil fill cap on the engine.
3. Place a 2 quart minimum capacity container under the
end of the oil drain (Figure 22).
4. Remove or open the oil drain plug (A or B, Figure 22),
depending upon the type of oil drain plug the engine is
equipped with.
NOTE: Location of oil drain may vary according to model.

of used oil properly.
