CARBURETOR ADJUSTMENT

WARNING:

Keep others away when

making idle speed adjustments. The trimmer

head, blade or any optional attachment will be

spinning during most of this procedure. Wear

your protective equipment and observe all safe-

ty precautions. After making adjustments, the

trimmer head, blade or any optional attachment

must not move/spin 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

Engine will not idle when the throttle is

released.

S

The trimmer head, blade or optional

attachment moves/spins at idle.

Make adjustments with the unit supported so

the cutting attachment is off the ground and

will not make contact with any object. Hold

the unit by hand while running and making ad-

justments. Keep all parts of your body away

from the cutting attachment and muffler.

Idle Speed Adjustment

Allow engine to idle. Adjust speed until engine

runs without trimmer head, blade or optional

attachment moving or spinning (idle too fast)

or stalling (idle speed too slow).
S

Turn idle speed screw clockwise to

increase engine speed if engine stalls or

dies.

S

Turn idle speed screw counterclockwise to

decrease engine speed if trimmer head,

blade or optional attachment moves or

spins at idle.

WARNING:

Recheck the idle speed

after each adjustment. The trimmer head,

blade or optional attachment must not move

or spin at idle speed to avoid serious injury to

the operator or others.
