CheCking The oil level

See the BEFORE STARTING THE ENGINE section
on page 3 for information on checking the oil level.
The oil level should be checked before each use, or
at least every eight (8) hours of operation. Keep the
oil level maintained.
Changing The oil and oil filTeR

Your engine may be equipped with an oil filter.
Change the oil and filter after the first eight (8)
hours of operation. Change the oil and oil filter (if so
equipped) every 100 hours thereafter. If using this
engine under dirty or dusty conditions, or in extreme-
ly hot weather, change the oil more often.
Use the following instructions to change the oil while
the engine is still warm:
1. Clean the area around the oil drain plug, remove
the plug and drain the oil completely into a suit-
able container (Figure 5).
Placing the engine on a flat surface will allow
complete drainage. Tipping the engine towards
the drain plug will not allow complete drainage.
Figure 6 — Oil Filter and Drain Plug
2. When the oil is drained, install and tighten the oil
drain plug.
3. If the engine is equipped with an oil filter, use
the following instructions:
A. Place a suitable container beneath the oil
filter and turn the filter counterclockwise to
remove the filter.
B. Coat the gasket of a new filter with engine oil.
Turn the new filter clockwise until the gasket
contacts the filter adapter, then tighten an
additional 3/4 turn.

4. Remove the oil fill plug and insert a clean funnel
into the plug opening. Fill the crankcase with the
recommended oil. POUR SLOWLY. The appropri-
ate crankcase oil capacity is listed in the table on
Page 2. The amount of oil required to refill the
crankcase will vary depending on how well the
crankcase has been drained.
5. When the crankcase is filled to the proper level,
install and tighten the oil fill plug. Start engine and
run for 30 seconds to fill oil filter.
6. Shut off the engine and recheck/correct oil level.
seRviCing The aiR CleaneR

This engine's air cleaner is one of the most important
areas to maintain. The engine will not run properly
and may get damaged if it is run with a dirty air
cleaner system.
Clean or replace the paper air filter (Figure 7) every
50 hours of operation or once a year, whichever
comes first. Clean or replace the filter more often if
the engine is operated under dusty or dirty condi-
tions. Clean the foam pre-filter every 25 hours of
operation, or sooner under dusty or dirty conditions.
*
N ever run this equipment without the com-
plete air cleaner system installed on the
engine. This could result in premature wear to
the engine.
use the following instructions to clean or replace
the air cleaner components.
1. Loosen the two screws on the air cleaner cover.
Remove the air cleaner cover (Figure 7).
