Engine Maintenance
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 23).
4. Remove or open the oil drain plug (A or B, Figure 23),
depending upon the type of oil drain plug the engine is
equipped with.
NOTE: Location of oil drain may vary according to model.
5. After all the oil has drained, replace or close the drain
plug, and wipe up any oil that may have spilled. Dispose
of used oil properly.
6. Fill the engine with new oil. Refer to "How To Check/Add
Oil" in the Operation Section.
How To Change The Oil Filter (if equipped)
Some models are equipped with oil filter. For replacement
intervals, see the Maintenance chart.
1. Drain the oil from the engine. Refer to "How To Change
The Engine Oil".
2. Remove the oil filter (A, Figure 24) and dispose of prop-
erly.
NOTE: Location of oil filter may vary according to model.
3. Before you install the new oil filter, lightly lubricate the oil
filter gasket with fresh, clean oil.
4. Install the oil filter by hand until the gasket contacts the
oil filter adapter, then tighten the oil filter 1/2 to 3/4 turns.
5. Add oil. Refer to "How to Check/Add Oil" in the Operation
section.
6. Start and run the engine. As the engine warms up, check
for oil leaks.

How To Service The Air Filter

sive. Fire or explosion can cause severe burns or death.
