g) Do not use a damaged accessory. Before
each use, inspect the accessory such as
abrasive wheels for chips and cracks,
backing pads for cracks, tears or excess
wear, wire brushes 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.
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 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.
i) Keep bystanders a safe distance away
from the 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.
j) Hold the power tool only by the
insulated gripping surfaces when
performing an operation where the
sanding tool may contact hidden wiring
or its own power cord. Contact with a
"live" wire will also make exposed metal
parts of the power tool "live" and shock the
operator.
k) Position the cord clear of the spinning
accessory. If you lose control of the power
tool, the cord may be cut or snagged and
your hand or arm may be pulled into the
spinning accessory.

Operating instructions
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
p) 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 move-
ment at the point of pinching.
Abrasive wheels may also break under these
conditions. Kickback is the result of power tool
misuse and/or In correct operating procedures
or conditions and can be avoided by taking
proper precautions as given below.
