If the service indicator does not reset easily, or if the
yellow core does not latch at the greatest vacuum,
the service indicator should be replaced. If the new
service indicator will not reset, the hole for the service
indicator may be restricted.
The service indicator may need to be replaced
frequently in environments that are severely dusty.

NOTICE
Perform this maintenance with the engine stopped.
1.
Maintain the oil level between
“
ADD
”
mark (Y) and
“
FULL
”
mark (X) on oil level gauge (1). Do not fill
the crankcase above
“
FULL
”
mark (X).
NOTICE
Operating your engine when the oil level is above the
“
FULL
”
mark could cause your crankshaft to dip into
the oil. The air bubbles created from the crankshaft
dipping into the oil reduces the oil's lubricating char-
acteristics and could result in the loss of power or en-
gine failure.
2.
Remove the oil filler cap and add oil, if necessary.
Clean the oil filler cap. Install the oil filler cap.
