GENERAL MAINTENANCE
RECOMMENDATIONS
The owner/operator is responsible for making sure that all
periodic maintenance tasks are completed on a timely
basis; that all discrepancies are corrected; and that the
equipment is kept clean and properly stored. Never operate
a damaged or defective engine.
CAUTION: Before working on this engine, disconnect
the spark plug wires from the spark plugs and place
the wires where they cannot come in contact with the
spark plugs.
CHECKING THE OIL LEVEL
See the “BEFORE STARTING THE ENGINE” section on
page 4 for information on checking the oil level. The oil level
should be checked before each use, or at least every eight
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 hours of operation.
Change the oil every 50 hours thereafter. If you are using
this engine under dirty or dusty conditions, or in extremely
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 suitable container (Figure 4).
Figure 4 – Oil Drain
2. When the oil is drained, install and tighten the oil drain plug.
3. If your 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 cap and insert a clean funnel into the cap opening.
Fill the crankcase with the recommended oil until the oil level is at the
FULL mark. Approximately 1,420 mL (48 oz) are required without an
oil filter; 1650 mL (56 oz) with an oil filter. POUR SLOWLY.
5. When the crankcase is filled to the proper level, install and tighten the
oil fill cap.
SERVICING THE AIR CLEANER
Your equipment’s air cleaner is one of the most important
areas to maintain. This engine will not run properly and may
get damaged if it is run with a dirty air cleaner system.
Clean the foam pre-cleaner every 25 hours of operation,
or sooner under dusty or dirty conditions. Clean or replace
the paper air filter (Figure 5, page 6) 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 conditions.
CAUTION: Never run this equipment without the
complete air cleaner system installed on the engine.
This could result in premature wear to the engine.
