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: Disconnect the spark plug wire from the spark
plug, and place the wire where it cannot come in contact with
the spark plug before working on this engine.
CHECKING THE OIL LEVEL
See the BEFORE STARTING THE ENGINE section on page 6 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 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 6).
Figure 6 — Oil Filter and Drain Plug
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 plug and insert a clean funnel into the
plug opening. Fill the crankcase with the recommended
oil until the oil level is at point of overflowing. Approxi-
mately 620ml (21 oz.) are required without an oil filter;
770ml (29 oz.) with an oil filter. POUR SLOWLY.
5. When the crankcase is filled to the proper level, install
and tighten the oil fill plug.
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 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 conditions. Clean the foam pre-filter
every 25 hours of operation, or sooner under dusty or dirty
conditions.
