equately guarded or controlled.
g) The arbour size of wheels and flanges
must properly fit the spindle of the
power tool. Wheels and flanges with ar-
bour holes that do not match the mounting
hardware of the power tool will run out of
balance, vibrate excessively and may cause
loss of control.
h) Do not use damaged wheels. Before
each use, inspect the wheels for chips
and cracks. If power tool or wheel is
dropped, inspect for damage or install
an undamaged wheel. After inspecting
and installing the wheel, position your-
self and bystanders away from the plane
of the rotating wheel and run the power
tool at maximum no load speed for one
minute. Damaged wheels will normally
break apart during this test time.
i) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hear-
ing 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 fil-
trating particles generated by your opera-
tion. Prolonged exposure to high intensity
noise may cause hearing loss.
j) Keep bystanders a safe distance away
from work area. Anyone entering the
work area must wear personal protec-
tive equipment. Fragments of workpiece
or of a broken accessory may fly away and
cause injury beyond immediate area of op-
eration.
k) Hold the power tool by insulated grip-
ping 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 opera-
tor an electric shock.
l) 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 wheel.
m) 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.
n) Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your cloth-
ing, pulling the accessory into your body.
o) Regularly clean the power tool's air
vents. The motor's fan will draw the dust
inside the housing and excessive accumula-
tion of powdered metal may cause electrical
hazards.
p) Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
q) Do not use accessories that require
liquid coolants. Using water or other liq-
uid coolants may result in electrocution or
shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched
or snagged rotating wheel. Pinching or snag-
ging causes rapid stalling of the rotating wheel
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of
the wheel'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 incorrect operating procedures or con-
ditions 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 al-
low you to resist kickback forces. Al-
