AIR FILTER
CAUTION: Do not clean filter in gasoline or
other flammable solvent to avoid creating a
fire hazard or producing harmful evaporative
emissions.
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
dusty conditions. A used air filter can never
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.

California to cause cancer.

CARBURETOR ADJUSTMENTS
The chain will be moving during most of this
procedure. Wear your protective equipment
and observe all safety precautions. The
chain must not move at idle speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if
you notice any of the following conditions:
S
Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Saw will not idle. See IDLE SPEED--T ad-
justing procedure.
Idle Speed---T
Allow engine to idle. If the chain moves, idle
is too fast. If the engine stalls, idle is too slow.
Adjust speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow).
S
Turn idle speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.If you re-
quire further assistance or are unsure about
performing this procedure, contact your au-
thorized service dealer.
