SERVICE AND ADJUSTMENTS
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.

5.Insert ends of line one at a time through the line exit tunnels.
6.Pull the line and make sure the line is ex- tended fully through the tunnels.

7.Correctly installed line will be the same length on both ends.
REPLACING THE CUTTING HEAD
1.Align hole in the dust cup with the hole in the side of the gearbox by rotating the dust cup.
2.Insert a small screwdriver into aligned holes. This will keep the shaft from turning while removing and installing trimmer head.

CARBURETOR IDLE SPEED
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.
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).
STurn idle speed screw clockwise to increase
engine speed if engine stalls or dies.
STurn 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.
