CARBURETOR IDLE SPEED
ADJUSTMENT
WARNING:
Keep others away when
making idle speed adjustments. The chain
will be moving during most of this procedure.
Wear your protective equipment and observe
all safety precautions. After making adjust-
ments, the chain must not move at idle speed.
The carburetor has been carefully set at the
factory. Adjustment to the idle speed may be
necessary if you notice any of the following
conditions:
S
Engine will not idle when the throttle is re-
leased.
S The chain moves at idle.
Make adjustments with the unit supported so
the pruner is off the ground and the chain will
not make contact with any object. Hold the
unit by hand while running and making adjust-
ments. Keep all parts of your body away from
the chain and muffler.
Idle Speed Screw
To adjust idle speed:
Allow engine to idle. Adjust idle speed until en-
gine runs without chain moving (idle too fast)
or stalling (idle speed too slow).
S
Turn idle speed screw clockwise to in-
crease engine speed if engine stalls or dies.
S Turn idle speed screw counterclockwise to
decrease engine speed if chain moves at idle.
WARNING:
Recheck the idle speed
after each adjustment. The chain must not
move at idle speed to avoid serious injury to
the operator or others.
If you require further assistance or are unsure
about performing this procedure, contact your
authorized service dealer or call
1--800--554--6723.

beled IMPORTANT regarding the use of ga-
sohol in your engine.
Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits
during storage. Add stabilizer to the gasoline
in the fuel tank or fuel storage container. Fol-
low the mix instructions found on stabilizer
container. Run engine at least 5 minutes after
adding stabilizer.

rate from the gas.
We recommend that you
shake the gas can weekly
to insure proper blending of
the gas and oil.

mended type and heat range.
S Clean air filter.
S Check entire unit for loose screws, nuts,
and bolts. Replace any damaged, broken,
or worn parts.

only fresh fuel having the proper gasoline to
oil ratio.
