CHECK
CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-
ENING in the SERVICE AND ADJUST-
MENTS section.
BAR MAINTENANCE
If your pruner cuts to one side, has to
be forced through the cut, or been run
with an improper
amount of bar lubri-
cation it may be necessary
to service
your bar. A worn bar will damage your
chain and make cutting difficult.
After each use, ensure ON/OFF switch is
in the OFF position, then clean all saw-
dust from the guide bar and sprocket
hole.
To maintain guide bar:
• Move ON/OFF switch to the OFF posi-
tion and disconnect
spark plug (or dis-
connect powerhead from power
source).
• Loosen and remove
bar clamp nut
and chain brake. Remove bar and
chain from pruner.
• Clean the oil holes and bar groove
after each 5 hours of operation.
