INSTALLATION OF THE METAL
BLADE
WARNING: Wear protective gloves
when handling or performing maintenance on
the blade to avoid injury. The blade is sharp and
can cut you even when it is not moving.
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 shaft and not in the parts
bag. All other fasteners mentioned in the follow-
ing assembly steps are in the parts bag.
1.
Remove the retaining washer from the
threaded shaft of the gearbox. Leave the
dust cup on the shaft.
2. Install the blade and the retaining washer
over the threaded shaft.
3. 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.
4. Slide the blade and retaining washer onto
the shaft of the gearbox.
5. Place the cupped washer onto the shaft.
Make sure the cupped side of the washer
is toward the blade.
6. Install the blade nut by threading onto the
shaft counterclockwise.

NOTE: Make sure all parts are in place as il-
lustrated, and the blade is sandwiched between
the dust cup and the retaining washer. There
should be no space between the blade and the
dust cup or the retaining washer.
7.
Align hole in dust cup with hole in side of
gearbox by rotating the blade.
8. Insert a small screwdriver into aligned
holes. This will keep the shaft from turn-
ing while tightening the blade nut.

9. TIghten blade nut firmly with a wrench while
holding screwdriver in position.
10. Remove the screwdriver.
11. Turn blade by hand. If the blade binds
against the shield, or appears to be uneven,
the blade is not centered, and you must re-
install.
NOTE: To remove blade, insert screwdriver
into aligned holes. Unthread the nut and re-
move parts. Be sure to store parts and instruc-
tions for future use.
