SCALPING - The scalping technique
removes unwanted vegetation. Hold bot-
tom of trimmer head about 3 in. (8 cm)
above ground and at an angle. Allow tip
of line to strike the ground around trees,
posts, monuments, etc. This technique
increases line wear.
Scalping
MOWING - Your trimmer is ideal for
mowing in places conventional lawn
mowers cannot reach. In the mowing
position, keep line parallel to ground.
Avoid pressing head into ground as this
can scalp ground and damage tool.

SWEEPING - The fanning action of
rotating line can be used for a quick
and easy clean up. Keep line parallel
to and above the surfaces being swept
and move the tool from side to side.

OPERATING INSTRUCTIONS FOR
USE WITH A BLADE
• Blade Thrust is a reaction that only oc-
curs 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 spinning
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 '_hrusting" reaction can
be violent enough to cause operator to
be propelled in any direction and lose
control of unit. The uncontrolled unit
can cause serious injury if blade con-
tacts operator or others.
• WHEN BLADE THRUST OCCURS.
Blade thrust can occur without warn-
ing if the blade snags, stalls, or
binds. This is more likely to occur in
areas where it is difficult to see the
material 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 in diameter with
weed blade. Do not let blade contact
material it cannot cut such as stumps,
rocks, fences, metal, etc., or clusters
of hard, woody brush with a diameter
greater than that recommended.
• 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 right to your left.
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,
