PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of
children and infi rm persons.
SAFETY WARNINGS COMMON FOR
GRINDING OPERATIONS
a) This power tool is intended to function as a grinder.
Read all safety warnings, instructions, illustrations
and specifi cations 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,
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 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 grinding accessories must be
at least equal to the maximum speed marked on the
power tool.
Grinding 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
controlled.
f) The arbour size of wheels, sanding drums or any
other accessory must properly fi t the spindle or
collet of the power tool.
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) Mandrel mounted wheels, sanding drums, cutters
or other accessories must be fully inserted into the
collet or chuck.
If the mandrel is insuffi ciently held and/or the overhang
of the wheel is too long, the mounted wheel may become
loose and be ejected at high velocity.
h) Do not use a damaged accessory. Before each us
inspect the accessory such as abrasive wheels for
chips and cracks, sanding drum for cracks, tear or
excess wear, wire brush 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.
i) 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 fl ying
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.
j) 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
fl y away and cause injury beyond immediate area of
operation.
k) Hold power tool by insulated gripping 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 operator an electric shock.
l) Always hold the tool fi rmly in your hand(s) during
the start-up.
The reaction torque of the motor, as it accelerates to full
speed, can cause the tool to twist.
m) Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other hand while in use.
Clamping a small workpiece allows you to use your
hand(s) to control the tool. Round material such as
dowel rods, pipes or tubing have a tendency to roll while
being cut, and may cause the bit to bind or jump toward
you.
n) 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.
o) 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.
p) After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other
adjustment devices are securely tightened.
Loose adjustment devices can unexpectedly shift,
causing loss of control, loose rotating components will
be violently thrown.
q) 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.
r) 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.
s) Do not operate the power tool near fl ammable materials.
Sparks could ignite these materials.
t) 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, sanding band, 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.
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 fi rm grip on the power tool and position your
body and arm to allow you to resist kickback forces.
The operator can control kickback forces, if proper
precautions are taken.
