and run the power tool at maximum no-load
speed for one minute. Damaged accessories will
normally break apart during this test time.
i) Wear personal protective equipment. Depen-
ding on application, use face shield, safety gog-
gles 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 fl ying debris generated
by various operations. The dust mask or respi-
rator must be capable of fi ltrating particles ge-
nerated 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 work-
piece or of a broken accessory may fl y away and
cause injury beyond immediate area of operation.
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 fi rmly 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 toward you.
n) Position the cord clear of the spinning acces-
sory. 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 spin-
ning 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 com-
ponents 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 fl ammable
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.
Further safety instructions for all operations:
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 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 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.
