install an undamaged accessory.
After inspecting and installing an
accessory, position yourself and
bystanders away from the plane
of the rotating accessory and run
the power tool at maximum no-load
speed for one minute. Damaged
accessories will normally break apart
during this test time.
■ 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 operations. 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.
■ 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 operation.
■ Hold power tool by insulated
gripping surfaces only, when
performing an operation where the
cutting accessory may contact
hidden wiring. Cutting accessory
contacting a "live" wire may make
exposed metal parts of the power
tool "live" and could give the
operator an electric shock.
■ Always hold the tool firmly in
your hand(s) during the start-up.

Original Instructions
The reaction torque of the motor,
as it accelerates to full speed, can
cause the tool to twist.
■ 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.
■ 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.
■ Never lay the power tool down
until the accessory has come
to a complete stop. The spinning
accessory may grab the surface and
pull the power tool out of your control.
■ After changing the bits or making
any adjustments, 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.
■ 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.
■ 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.
