ROUTINE AND PERIODIC
MAINTENANCE

ENGINE MAINTENANCE

To prevent the engine from accidentally starting, dis-
connect the negative battery cable before servicing the
engine.
See Table D.1 for a summary of maintenance intervals
for the items listed below. Follow either the hourly or
the calendar intervals, whichever come first. More fre-
quent service may be required, depending on your spe-
cific application and operating conditions.
OIL: Check the oil level after every 8
hours of operation or daily. BE SURE
TO MAINTAIN THE OIL LEVEL.
Change the oil the first time between 25 and 50 hours
of operation. Then, under normal operating conditions,
change the oil as specified in Table D.1. If the engine is
operated under heavy load or in high ambient temper-
atures, change the oil more frequently.
CHANGE THE OIL: Change the oil, while the engine
is still warm, as follows:
1 . Drain the oil from the drain plug located on the
engine bottom, as shown in Figure D.1. Examine
the washer and replace it if it appears damaged.
2. Replace the plug and washer and tighten to 25 ft.-
lb. (34 Nm).
3. Remove the oil fill cap and add oil until the level
reaches the "MAX" mark on the dipstick.
Figure D.1. Use high quality oil viscosity grade
10W30. Consult the engine manual for oil specifi-
cations. Always check the level with the dipstick
before adding more oil.
4. Reinstall the oil fill cap and the dipstick.
