SAFETY WARNINGS FOR GRINDING
OPERATIONS
a)
This power tool is intended to function as a
grinder. Read all safety warnings, instructions,
illustrations and specifications provided with
this power tool.
Failure to follow all instructions listed below may
result in electric shock, fi re and/or serious injury.
b)
Operations such as sanding, wire brushing or
polishing or cutting-off are not recommended to
be performed with this power tool.
Operations for which the power tool was not designed
may create a hazard and cause personal injury.
c)
Do not use accessories which are not specifically
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 fl y 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 fl anges, the arbour hole of the accessory must
fi t the locating diameter of the fl ange.
Accessories that do not match the mounting hardware of
the power tool will run out of balance, 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. 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 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 fi ltrating
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 operation.
j)
Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting tool may contact hidden wiring.
Contact with a "live" wire will also 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 spinning
accessory.
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 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.
