CHAIN SHARPENING
Chain sharpening is a complicated task that
requires special tools. We recommend that
you refer chain sharpening to a professional
chain sharpener.
CARBURETOR ADJUSTMENTS
WARNING
: The chain will be moving
during most of this procedure. Wear your pro-
tective equipment and observe all safety pre-
cautions. 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). The idle speed screw is located in the
area above the primer bulb and is labeled T.
S Turn idle speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.

STORAGE
WARNING
cool, and secure the unit before storing or
transporting in a vehicle. Store unit and fuel
in an area where fuel vapors cannot reach
sparks or open flames from water heaters,
electric motors or switches, furnaces, etc.
Store unit with all guards in place. Position so
that any sharp object cannot accidentally
cause injury to passersby. Store the unit out
of reach of children.
S Before storing, drain all fuel from the unit.
Start engine and allow to run until it stops.
S Clean the unit before storing. Pay particu-
lar attention to the air intake area, keeping
it free of debris. Use a mild detergent and
sponge to clean the plastic surfaces.
S Do not store the unit or fuel in a closed area
where fuel vapors can reach sparks or an
open flame from hot water heaters, electric
motors or switches, furnaces, etc.
S Store in a dry area out of the reach of chil-

CAUTION
: It is important to prevent
gum deposits from forming in essential fuel
system parts such as the carburetor, fuel fil-
ter, fuel hose, or fuel tank during storage. Al-
cohol blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
