OPERATING POSITION
NOTE: This brushcutter attachment is
not designed for use with electric powerheads.
When operating unit with brushcutter
attachment, clip shoulder strap onto
upper shoulder strap clamp, stand as
shown and check for the following:
• Wear eye protection and heavy
clothing.
• Keep arms extended with right hand
holding the trigger handle of powerhead.
• Keep left arm extended with left hand
holding the handlebar.
• Keep unit below waist level.
• Shoulder strap pad should be cen
tered on your left shoulder and dan
ger sign centered on your back.
• Maintain full weight of tool on left
shoulder.
• Without bending over, keep the blade
near and parallel to the ground and
not crowded into material being cut.
OPERATING INSTRUCTIONS FOR
BRUSHCUTTER ATTACHMENT
• Blade Thrust is a reaction that only
occurs when using a bladed unit. This
reaction can cause serious injury such
as amputation. Carefully study this
section. It is important that you under
stand what causes blade thrust, how
you can reduce the chance of its oc
curring, and how you can remain in
control of unit if blade thrust occurs.
• WHAT CAUSES BLADE THRUST Blade Thrust can occur when spin
ning blade contacts an object that it
does not cut. This contact causes
blade to stop for an instant and then
suddenly move or “thrust” away from
object that was hit. The “thrusting” re
action can be violent enough to cause
operator to be propelled in any direc
tion and lose control of unit. The un
controlled unit can cause serious injury
if blade contacts operator or others.
WHEN BLADE THRUST OCCURS
- Blade Thrust can occur without
warning if the blade snags, stalls, or
binds. This is more likely to occur in
areas where it is difficult to see the
materia! being cut. By using the unit
properly, the occurrence of blade
thrust will be reduced and the opera
tor will be less likely to lose control.
Cut only grass, weeds, and woody
brush up to 1/2 inch (1 cm) in diameter
with weed blade. Do not let blade con
tact material it cannot cut such as
stumps, rocks, fences, metal, etc., or
clusters of hard, woody brush with a
diameter greater than 1/2 inch (1 cm).
Use a sharp blade. A dull blade is
more likely to snag and thrust.
Cut only at full throttle. The blade will
have maximum cutting power and is
less likely to bind or stall.
“Feed” the blade deliberately and not
too rapidly. The blade can thrust
away if it is fed too rapidly.
Cut only from your left to your right.
Swinging unit in the same direction as
blade spin increases cutting action.
Use the shoulder strap and keep a
firm grip on the unit with both hands.
A properly adjusted shoulder strap
will support the weight of the unit,
freeing your arms and hands to con
trol and guide the cutting motion.
Keep feet comfortably spread apart
and braced for a possible sudden,
rapid thrust of unit. Do not overreach.
Keep firm footing and balance.
• Keep blade below waist level, it will
be easier to maintain control of unit.
• Do not raise the engine above your
waist as the blade can come danger
ously close to your body.
• Do not swing the unit with such force
that you are in danger of losing your
balance.
Bring the powerhead engine to cutting
speed before entering the material to
be cut.
If the blade does not turn when you
squeeze the throttle trigger of the pow
erhead, make sure the attachment is
fully inserted into the coupler.
Always release the throttle trigger and
allow powerhead engine to return to
idle speed when not cutting. The blade
should not turn while the engine is run
ning at idle. If the blade turns at idle,
do not use your unit. Refer to the CAR
BURETOR ADJUSTMENT section of the
powerhead manual or contact your
Sears Service Centre.
• Maintain good firm footing while us
ing the unit. Do this by planting feet
firmly in a comfortable apart position.
• Cut while swinging the upper part of
your body from left to right.
• As you move forward to the next
area to cut, be sure to maintain your
balance, and footing.
RECOMMENDED CUTTING POSITION
Cut using the 2
o’clock to 4 o'clock
position of the
blade
2 o'clock
4 o’clock
mk WARNING: The operator or others
must not try to clear away cut material
with the engine running or the blade
turning to avoid serious injury. Stop en
gine and blade before removing materi
als wrapped around blade or shaft.

SERVICE AND ADJUSTMENTS
BLADE REPLACEMENT
^ WARNING: The blade will contin
ue to spin after the engine stops or af

leased. To avoid serious injury, make
sure the blade has stopped coasting
and disconnect the spark plug before
performing work on the 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.
1. To remove the blade, align hole in
the dust cup with the hole in the
side of the gearbox by rotating the
biade.
2. Insert a small screwdriver into
aligned holes. This will keep the
shaft from turning while loosening
the blade nut.
3.10While holding the screwdriver in
position, remove blade nut by turn
ing clockwise as you are facing the
nut.
Romove both washers and the
blade from the blade shaft. Leave
the dust cup on the gearbox,
install new blade and retaining
washer onto the threaded shaft ex
tending from the gearbox (blade
must be 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.
STORAGE
a WARNING: Perform the following
steps after each use:
• Allow attachment and gearbox to
cool before storing or transporting.
• Store attachment with blade shield in
place. Position attachment so that
any sharp object cannot accidentally
cause injury.
• Store the attachment in a dry, well
ventilated area out of the reach of
children.
SEASONAL STORAGE
Prepare attachment for storage at end
of season or if it will not be used for 30
days or more.
if your brushcutter attachment is to be
stored for a period of time:
6. Place the cupped washer onto the
shaft. Make sure the cupped side
of the washer is toward the blade.
7. Install blade nut by threading onto
the shaft counterclockwise as you
are facing the nut.
NOTE: Make sure all parts are in place
as illustrated, 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.
8. Tighten blade nut firmly with a
wrench while holding screwdriver
in position.
9. Remove the screwdriver.
10. Turn blade by hand, if the blade
binds against the shield, or ap
pears to be uneven, the blade is
not centered, and you must rein
stall.
Clean the entire attachment.
Inspect the blade shield area and
clean any dirt, grass, leaves, or de
bris that has collected. Inspect the
blade and blade shield; replace a
blade that is bent, warped, cracked,
broken or damaged in any other way.
Lightly oil external metal surfaces.
Apply a coating of oil to the entire
surface of the blade; wrap it in heavy
paper or cloth.
Check entire attachment for loose
screws or nuts. Replace any dam
aged, worn or broken parts.
At the beginning of the next season,
use only fresh fuel having the proper
gasoline to oil ratio.
