h) 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 eye

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.

j) 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 shock the operator.

Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged 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.
snagged 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 kickout. 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.

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. Always use
auxiliary handle, if provided, for
maximum control over kickback or
torque reaction during start-up. The
operator can control torque reactions or
kickback forces, if proper precautions are
taken.

d) Use special care when working corners,
sharp edges etc. Avoid bouncing and

edges or bouncing have a tendency to snag
the rotating accessory and cause loss of
control or kickback.
