CAUTION!
Over-lubricating may cause the

gearcase to run slower than normal,
and may also cause leakage from
excess grease.

lever-type grease gun to force 1–2 strokes
of high quality lithium-based grease
through the gearcase grease fitting.
Remove and clean the spark plug.
Adjust the spark plug electrode gap to

spark plug must be replaced, use only the
spark plug recommended on the Specifica-
tions section or an equivalent resistor type
spark plug of the correct heat range.
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent
dirt and debris from getting into the
engine’s internal parts. .
