CARBURETOR ADJUSTMENTS
Carburetor adjustment is c ritical and if done
improperly can permanently damage your
unit. We recommend y ou contact an Autho-
rized Service Dealer for adjustments.
IDLE SPEED ADJUSTMENT:
Turn the Idle
Speed Screw clockwise until it stops. Now
turn the screw counterclockwise 4 -1/2 turns.
This should allow the engine to run without
the chain turning. If the chain moves at idle
speed, do not use your unit. Contact an Au-
thorized Service Dealer. Idle speed is cor-
rect when engine runs without stalling and
chain does not turn.
MIXTURE ADJUSTMENTS:
If your carbu-
retor includes limiter caps (Plastic caps on
the mixture screws) , do not force the screws
beyond the stops of the limiter caps or dam-
age will occur. Do not remove these caps.
Small adjustments will affect your unit. Do
not adjust more than 1/16th turn without
checking performance.
CHAIN SHARPENING

guide. (See the back page of this manual for
the toll-free phone number.)

Before storing, drain all fuel from the
unit. Start engine and allow to run until it

CAUTION:
It is important to prevent gum de-
posits from forming in essential fuel system
parts such as t he carburetor, fuel filter, fuel
hose, or fuel tank during storage. Alcohol
blended fuels (called gasohol or using

which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
