• CARBURETOR ADJUSTMENT
WARNING:
Keep others away when making idle speed
adjustments. The trimmer head will be spinning during
most of this procedure. Wear your protective equipment
and observe all safety precautions. After making
adjustments, the trimmer head 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:
-
Engine will not idle when the throttle is released.
-
The trimmer head moves/spins at idle speed.
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 adjustments. 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 moving or spinning (idle speed too
fast) or engine stalling (idle speed too slow).
- Turn idle speed screw clockwise to increase engine
speed if engine stalls or dies.
-
Turn idle speed screw counterclockwise to decrease
engine speed if trimmer head moves or spins at idle
speed.
WARNING:
Recheck the idle speed after each
adjustment. The trimmer head must not move or spin at
idle speed to avoid serious injury to the operator or
others.
