INSTALLATION OF THE METAL
BLADE
WARNING: Do not use any blades, or
fastening hardware other than the washers and
nuts shown in the following illustrations. These
parts must be provided by Poulan/Weed Eater,
and installed as shown below. Failure to use
proper parts can cause the blade to fly off and
seriously hurt you or others.
NOTE: The dust cup and retaining washer are
located on the gearbox and not in the parts bag.
S
Remove the retainer washer from the gear-
box, and leave the dust cup on the gearbox.
NOTE: It may be necessary to remove a
plastic protective covering from the
threaded shaft before removing the retain-
ing washer.

Dust Cup
S Install the blade over the threaded shaft ex-
tending from the gearbox between the dust
cup and the retaining washer. Make sure
the raised part of the retaining washer is
facing the gearbox, and the raised area fits
into the hole in the center of the blade.
S Slide the blade and retaining washer onto
the shaft of the gearbox.
S Now place the cupped washer onto the
shaft. Make sure the cupped side of the
washer is toward the blade.

dust cup or the retaining washer.
S
Push in locking lever and hold.
S Rotate blade nut until the locking lever falls
into one of the grooves in the dust cup.
Locking Lever
S Continue to hold in locking lever. This will
keep the shaft from turning while tightening

against the shield, or appears to be uneven,
the blade is not centered, and you must re-
install.
