CARBURETOR AD J USTMENT

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

IDLE SPEED ADJUSTMENT

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

mended type and heat range.
