Maintenance and care
1. Gearcase grease fittings
Cleaning silencer
3. Slide the gearcase out of the tube. Using a grease gun,
pump lithium-base grease (about 10 grams) into the grease
fitting on the gearcase until you see old grease being purged
from the gearcase. Purged grease will be visible in the outer
tube cavity.
4. Clean up excess grease, then reassemble the gearcase
onto the outer tube. Make sure the index bolt fits into the hole
on the outer tube. Securely tighten both bolts.
Never operate the unit with a damage or missing silenc-
er or spark arrester. Operating with a missing or dam-
aged spark arrester is a fire hazard, and could also
damage your hearing.
Carbon deposits in silencer will cause a drop in engine output
and overheating. Spark arrestor screen must be checked pe-
riodically. Clean deposits from silencer.
IMPORTANT
Do not remove the silencer cover. If necessary, Please consult
your dealer.
