CAUTION
: Do not clean filter in gasoline
or other flammable solvent to avoid creating

Cleaning the air filter:
A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after 15
tanks of fuel or 5 hours of operation, which-
ever comes first. Clean more frequently in

be completely cleaned. It is advisable to re-
place your air filter with a new one after every
50 hours of operation,or annually, whichever
comes first.

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.
