your operation. Prolonged exposure to high in-
tensity noise may cause hearing loss.
j) Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken ac-
cessory may fl y away and cause injury beyond
immediate area of operation.
k) Hold power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting ac-
cessory contacting a "live" wire may make
exposed metal parts of the power tool "live"
and could give the operator an electric shock.
l) Always hold the tool firmly in your hand(s)
during the start-up. The reaction torque of the
motor, as it accelerates to full speed, can cause
the tool to twist.
m) Use clamps to support workpiece whenever
practical. Never hold a small workpiece in
one hand and the tool in the other hand
while in use. Clamping a small workpiece
allows you to use your hand(s) to control the
tool. Round material such as dowel rods, pipes
or tubing have a tendency to roll while being
cut, and may cause the bit to bind or jump to-
ward you.
n) Position the cord clear of the spinning ac-
cessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning accessory.
o) Never lay the power tool down until the ac-
cessory has come to a complete stop. The
spinning accessory may grab the surface and
pull the power tool out of your control.
p) After changing the bits or making any ad-
justments, make sure the collet nut, chuck
or any other adjustment devices are secu-
rely tightened. Loose adjustment devices can
unexpectedly shift, causing loss of control, loo-
se rotating components will be violently thrown.
q) Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
r) Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside the
housing and excessive accumulation of powde-
red metal may cause electrical hazards.

s) Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
t) Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, sanding band, brush or any
other accessory. Pinching or snagging causes rapid
stalling of the rotating accessory which in turn cau-
ses the uncontrolled power tool to be forced in the
direction opposite of the accessory's rotation.
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. Abra-
sive 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) Maintain a firm grip on the power tool and
position your body and arm to allow you
to resist kickback forces. The operator can
control kickback forces, if proper precautions
are taken.
b) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or boun-
cing have a tendency to snag the rotating ac-
cessory and cause loss of control or kickback.
c) Do not attach a toothed saw blade. Such blades
create frequent kickback and loss of control.
d) Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direc-
tion as the chips are thrown). Feeding the tool
in the wrong direction causes the cutting edge of
the bit to climb out of the work and pull the tool
in the direction of this feed.
e) When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide cut-
ters, always have the work securely clam-
