ROUTINE AND PERIODIC
MAINTENANCE
ENGINE MAINTENANCE
To prevent the engine from accidentally starting,
disconnect the spark plug lead before servicing
the engine.
---------------------------------------------------------------------
See the engine ownerʼs manual for a summary of
maintenance intervals for the items listed below.
Follow either the hourly or the calendar intervals,
whichever come first. More frequent service may be
required, depending on your specific application and
operating conditions. Table D.1 shows engine main-
tenance replacement parts and numbers.
OIL: Check the oil level after every 5
hours of operation or daily. BE SURE
TO MAINTAIN THE OIL LEVEL.
Change the oil the first time after 20 hours of opera-
tion. Then, under normal operating conditions, change
the oil after every 100 hours or once every 6 months
whichever occurs first. If the engine is operated under
heavy load or in high ambient temperatures, change
the oil every 25 hours.
Drain the oil from the drain plug located on either side
of the engine bottom, as shown in Figure D.1. Refill
through the oil fill plug until the oil reaches the top of
the fill hole. Use the grade and viscosity recommend-
ed in the engine ownerʼs manual.
