speed for one minute. Damaged accessories will
normally break apart during this test time.
i) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various opera-
tions. The dust mask or respirator must be capable
of filtrating particles generated by your operation.
Prolonged exposure to high intensity 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 accessory may fly away
and cause injury beyond immediate area of opera-
tion.
k) Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring or
its own cord. Cutting accessory 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 prac-
tical. Never hold a small workpiece in one hand
and the tool in the other hand while in use. Clamp-
ing 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 accessory.
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 acces-
sory 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 adjust-
ments, make sure the collet nut, chuck or any
other adjustment devices are securely tightened.
Loose adjustment devices can unexpectedly shift,
causing loss of control, loose 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 powdered metal may
cause electrical hazards.
s) Do not operate the power tool near flammable
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 acces-
sory. 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.
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 mate-
rial causing the wheel to climb out or kick out. The wheel
may either jump toward or away from the operator, de-
pending 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 incor-
rect 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 posi-
tion your body and arm to allow you to resist
