REPLACING THE LINE
For unit to operate properly, the cutting line
should be replaced when line becomes worn to
less than 3 inches in length from the edge of the
line exit tunnels on each side of the cutting head.
1. Remove and discard worn line before
installing new line.
2. Use only 0.115 inch (3 mm) diameter
Poulan PRO brand cut length line.
3. Insert one end of the line through the
positioning tunnel.
4. Continue to feed line through tunnel until
line is centered (leaving equal amounts
on each side). See illustration below.

REPLACING THE CUTTING HEAD

the side of the gearbox by rotating the
dust cup.

holes. This will keep the shaft from turning
while removing and installing trimmer head.

IDLE SPEED ADJUSTMENT
WARNING:
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. Adjustment of the idle speed may be
necessary if you notice any of the following
conditions:
Engine will not idle when the throttle is
released.
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.
To adjust idle speed:
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).
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,
blade or optional attachment moves or
spins at idle.
WARNING:
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.
