Remove the gearcase cover, and use sol-
vent and a soft brush to remove all old
grease from the gearcase. To refill, hand-
pack the gearcase with approximately
40–50 grams of high quality lithium-based
grease (50–70% of capacity). DO NOT
OVERFILL!

Every 20 and 100 hours

CAUTION!
Over-lubricating may cause the
Ŷgearcase to run slower than normal,
and may also cause leakage from
excess grease.
Do not remove the conrods from the
Ŷcutters. Conrod bearings can be lost
or damaged if disturbed.
Gearcase lubrication
Every 20 hours
Top off gearcase grease level by using a
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
0.024 - 0.028 inch (0.6 - 0.7 mm). If the
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. .

10 - 15 hour maintenance

(more frequently in dusty conditions)
Remove the air filter element, and wash 1. the element in clean, neutral solvent
