into the collet or chuck. If the mandrel is insufficiently
held and/or the overhang of the wheel is too long,the
MOUNTED WHEEL may become loose and be ejected
at high velocity.
g) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheel 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 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 operation.
j) Hold 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
k) Always hold the tool firmly 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.
l) 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.
m) 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.
n) 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.
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.
r) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.

ALL OPERATIONS
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 firm 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.
b) 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.
c) Do not attach a toothed saw blade. Such blades
create frequent kickback and loss of control.
d) Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips
are thrown). Feeding the tool in the wrong direction
causes the cutting edge of the bit to climb out of the
work and pull the tool in the direction of this feed.
e) When using rotary files, cut-off wheels, high-
speed cutters or tungsten carbide cutters, always
have the work securely clamped. These wheels
will grab if they become slightly canted in the
groove, and can kickback. When a cut-off wheel
grabs, the wheel itself usually breaks. When a
rotary file, high-speed cutter or tungsten carbide cutter
grabs, it may jump from the groove and you could lose
control of the tool.
NOTE: Only those accessories that are listed are permitted to
be used with the tool.
