protectors, gloves and shop 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 shock the
operator.
 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.
 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 both hands 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.
 Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
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.

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.
