b) Operations such as sanding, wire brushing, pol-
ishing or cutting-off are not recommended to be
performed with this power tool. Operations for
which the power tool was not designed may cre-
ate a hazard and cause personal injury.
c) Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
d) The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fly apart.
e) 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.
f) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the ac-
cessory must fit the locating diameter of the
flange. Accessories that do not match the mount-
ing hardware of the power tool will run out of bal-
ance, vibrate excessively and may cause loss of
control.
g) 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 acces-
sory 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 acces-
sories 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 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.
i) 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 opera-
tion.
j) Hold the power tool by insulated gripping sur-
faces 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.
k) 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 spin-
ning accessory.
l) Never lay the power tool down until the acces-
sory 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 cool-
ants. 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.
