ASSEMBLY INFORMATION -- WEED
BLADE
WEED
BLADE
NOTE: Remove the trimmer head before
installing the weed blade. To remove the trimmer
head, align hole in the dust cup with the hole in
the side of the gearbox by rotating the dust cup.
Insert a small screwdriver into aligned holes.
This will keep the shaft from turning while loos-
ening the trimmer head. Remove the trimmer
head by turning clockwise. Remove the screw-
driver. See INSTALLATION OF THE CUTTING
HEAD for illustrations. Be sure to store all parts
and instructions for future use. Never use the
trimmer head with the metal blade installed.
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 McCulloch 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 is located on the gearbox
shaft and not in the parts bag. All other fasten-
ers mentioned in the following assembly steps
are in the parts bag.
1. Install the blade and the retaining washer
over the threaded shaft.
2. 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.
3. Slide the blade and retaining washer onto
the shaft of the gearbox.
4. Place the cupped washer onto the shaft.
Make sure the cupped side of the washer
is toward the blade.
5. 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.
6. Align hole in dust cup with hole in side of
gearbox by rotating the blade.
7. Insert a small screwdriver into aligned
holes. This will keep the shaft from turning
while tightening the blade nut.
8. Tighten blade nut firmly with a wrench (pro-
vided) while holding screwdriver in position.
9. Remove the screwdriver.
10. Turn blade by hand. If the blade binds
against the shield, or appears to be un-
even, the blade is not centered, and you
must reinstall.
NOTE: To remove blade, insert screwdriver
into aligned holes. Unthread the nut and remove
parts. Be sure to store parts and instructions for
future use.
ATTACHING THE TRANSPORT
GUARD
NOTE: The transport guard must always be
attached to the blade when the machine is be-
ing transported or in storage.
1. Remove ends of wire retainer from the
clips on the transport guard.
2. Lift wire retainer and position blade in
transport guard.
3. Place wire retainer over blade and insert
both ends of wire retainer back into clips.
