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, backing pad 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.
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
fl
ying
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
operation.
j) Hold the 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.
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.
a) Maintain a
fi
rm 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.
c) Do not position your body in the area where power
tool will move if kickback occurs.
Kickback will propel the tool in direction opposite to the
wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control
or kickback.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent kickback and loss of
control.
SAFETY WARNINGS SPECIFIC FOR
GRINDING OPERATIONS
a) Use only wheel types that are recommended for
your power tool and the speci
fi
c guard designed
for the selected wheel.
Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
