g) The outside diameter and the
thickness of your accessory must
be within the capacity rating of your
power tool. Incorrectly sized
accessories cannot be adequately
guarded or controlled.
h) The arbour size of wheels and
flanges must properly fit the spindle
of the power tool. Wheels and
flanges with arbour 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.
i) 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
yourself 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.
j) 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.

k) 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 wheel may fly away and
cause injury beyond immediate
area of operation.
l) Hold the 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 could give the
operator an electric shock.
n) 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.
o) 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.
p) 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.
q) Do not operate the power tool near
flammable materials. Sparks could
ignite these materials.

abrasive cutting-off operations
Kickback and related warnings
Kickback is a sudden reaction to a
pinched or snagged rotating wheel.
Pinching or snagging 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 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.
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.
b) Never place your hand near the
rotating accessory. Accessory may
kickback over your hand.
