harmful emissions. Always clean after every
5 hours of operation.

is removed.

BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be neces-
sary to service your bar. A worn bar will dam-
age your chain and make cutting difficult.
After each use, ensure ON/STOP switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
S Move ON/STOP switch to the STOP posi-
tion.
S Loosen and remove chain brake nuts and
chain brake. Remove bar and chain from
saw.
S Clean the oil holes and bar groove after each
5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Oil Hole
S Burring of guide bar rails is a normal
process of rail wear. Remove these burrs
with a flat file.
S When rail top is uneven, use a flat file to re-
store square edges and sides.
