General Maintenance
WARNING!
Before performing any maintenance,
repair, or cleaning work on the unit,
make sure the engine and cutting
attachment are completely stopped.
Disconnect the spark plug wire before
performing service or maintenance
work.
WARNING!
Non-standard accessories,
cutting attachment, or replacement
parts may not operate properly with
your unit and may cause damage and
lead to personal injury.
Prior to each work day, perform the
following:
Carefully remove any accumulations of
dirt or debris from the muffler and fuel
tank. Check cooling air intake area at
base of crankcase. Remove all debris.
Dirt build-up in these areas can lead to
engine overheating, fire, or premature
wear.
Daily Maintenance
Clean any debris or dirt from the cutting
attachment.
Lubricate the blades before use and
after refueling. Check the cutters for
damage or incorrect adjustment.
Check for loose or missing screws or
components. Make sure the cutter at-
tachment is securely fastened.
Check the entire unit for leaking fuel or
grease.
Make sure nuts, bolts, and screws
(except carburetor idle speed adjusting
screws) are tight.
10/15-Hour Maintenance
Lubricate the cutter assembly gearcase
by pumping one or two strokes of
lithium-base grease into the grease fit-
ting using a lever-type grease gun.
CAUTION!
Over lubricating can cause the
gearcase to operate sluggishly and
can cause grease to leak out.

50-hour Maintenance
Every 50 hours of operation
(more frequently in dusty or
dirty conditions):
Remove and clean the cylinder cover
and clean dirt and debris from the cylin-
der cooling fins.
Lubricate the gearcase.
To perform
this operation, first remove the gearcase
from the outer tube as follows:
CAUTION!
Do not remove the D-shaped shim
washer from the gearcase clamp! The
shim washer prevents damage from
overtightening the tube clamp screw.
a. Loosen the gearcase clamp bolt.
b. Remove the index bolt from the
gearcase.
c. Slide the gearcase out of the tube.
Using a grease gun, pump lithiumbase
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. 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.
