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:
CARBURETOR ADJUSTMENT
- 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.
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).
Idle Speed Adjustment
- 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.
7. With your finger between the lines, wrap
the lines evenly and firmly around the
spool in a clockwise direction.
