Kickback and Related Warnings
● Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the
binding.
● For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or
kick out. The wheel may either jump toward or away from the operator, depending on direction of the
wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions.
● Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given below.
a) Never place your and near t e rotating accessory. Accessory may kickback over your hand.
b) Do not position your body in t e area w ere power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
c) Use special care w en working corners, s arp edges etc. Avoid bouncing and snagging t e
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback.

CUTTING WITH NYLON HE D
For nearly all cutting, it is good to tilt the line
head
so that contact is made on the part of the line
circle where the line is moving W Y from you
and the debris shield. (See appropriate) This
results in the debris being thrown W Y from
you.
W RNIN
△
△△
△
! D NCER
The proper debris shield must be in place on the
unit when nylon cutting line is used, The cutting
line can flap around if too much line is exposed.
lways use the plastic debris shield with cut-off
knife when using nylon cutting heads.
W RNING
△
△△
△
! D NGER
Tilting the head to the wrong side will shoot the
debris TOW RDS you. If the line head is held flat to
the ground so that cutting occurs on the whole line
circle, debris will be THROWN at you, drag will slow
the engine down, and you will use up a lot of line.
W RNING
△
△△
△
! D NGER
Use only quality nylon monofilament line of the
diameter 2.5mm, Never use wire or wire-reinforced
line in place of nylon trimmer line. Load your nylon
line cutting head only with nylon trimmer line of the
proper diameter.
W RNING
△
△△
△
! D NGER
Use extreme caution when operating over bare spots
and gravel, because the line can throw small rock
particles at high speeds. Debris shields on the unit
cannot stop objects which bounce or ricochet off hard
surfaces.

11
CUTTING WITH NYLON HE D
TRIMMING:
This is feeding the trimmer carefully into the material
you wish to cut. Tilt the head slowly to direct debris
away from you. If cutting up to a barrier such as fence,
wall or tree, approach from an angle where any debris
ricocheting off the barrier will fly away from you, Move
the line head slowly until the grass is cut right up the
barrier, but do not jam (overfeed) the line into the
barrier. If trimming up to a wire mesh or chain linked
fence be careful to feed only up to wire. If you go to far
the line will snap off around the wire. Trimming can be
done to cut through weed stems one at a time. Place
the trimmer line head near the bottom of the
weed-never high up which could cause the weed to
chatter and catch the line. Rather than cut the weed
right through, just use the very end of the line to wear
through the stem slowly.

Do not to use a steel blade for edging or scalping.
SC LPING ND ENGING:
Both of these are done with the line head tilted at a steep
angle Scalping is removing top growth leaving the earth
bear.
Edging is trimming the grass back where it has spread
over a sidewalk or drive way. During both edging and
scalping, hold the unit a steep angle and in a position
where the debris, and any dislodging dirt and stones,
will not come back towards you even if it ricochets off
the hard surface. lthough the picture shows how to
edge and scalp every operator must find for himself the
angles which suits his body size and cutting situation.

That is using the side of the blade that it is rotating
away from you. Tilt down the blade slightly on this
same side. You will be hit by some debris if you
scythe in both directions.
Cut only with the side of the blade that the debris is
moving away from you.
If kickback occurs, the blade may be dull, or the
material so thick and hard that you should use other
tool instead of this machine.
Do not force the blade to cut. Do not change the
angle of cut after into the wood. void using any
pressure or leverage which could cause the blade to
