al and in the Engine Owner's Manual before working

ROUTINE AND PERIODIC
MAINTENANCE

ENGINE MAINTENANCE

To prevent the engine from accidentally starting, dis-
connect the spark plug leads before servicing the
engine.
See Table D.1 (Kohler engine) or D.2 (Onan Engine)
for a summary of maintenance intervals for the items
listed in Table D.3. Follow either the hourly or the cal-
endar intervals, whichever comes first. More frequent
servicing may be required, depending on your specific
application and operating conditions. See Figure D.1
for major component locations.
At the end of each day's use, refill the fuel tank to min-
imize moisture condensation in the tank. Running out
of fuel tends to draw dirt into the fuel system. Also,
check the crankcase oil level and add oil if indicated.
