Safety Warnings Common for Sanding or Polishing Operations
WARNING - Do not use a damaged accessory. Before each use inspect the accessory such as
abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire
brush for loose or cracked wires. If power tool or accessory is dropped, inspect for
damage or 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.
WARNING - 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.
WARNING - 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.
DANGER
- Hold the 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.
DANGER - 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.
DANGER - 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.
DANGER - 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.
DANGER - 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.
DANGER - Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
DANGER - 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, 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.
WARNING
- 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.
