Operations such as sanding or cutting-off are
f
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.
Do not use accessories which are not specifi-
f
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.
The rated speed of the grinding accessories
f
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
fly apart.
The outside diameter and the thickness of your
f
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can-
not be adequately controlled.
The arbour size of wheels, sanding drums or any
f
other accessory must properly fit 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.
Mandrel-mounted wheels, sanding drums, cut-
f
ters or other accessories must be inserted fully
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.
Do not use a damaged accessory. Before each
f
use 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 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.
Wear personal protective equipment. De-
f
pending on application, use face shield, safe-
ty 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 pro-
tection 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.
Keep bystanders a safe distance away from
f
work area. Anyone entering the work area must
wear personal protective equipment. Frag-
ments of workpiece or of a broken accessory may
fly away and cause injury beyond immediate area of
operation.
Hold power tool only by the insulated gripping
f
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory con-
tacting a "live" wire may make exposed metal parts
of the power tool "live" and could give the operator
an electric shock.
Always hold the tool firmly in your hand(s) dur-
f
ing the start-up. The reaction torque of the motor,
as it accelerates to full speed, can cause the tool to
twist.
Use clamps to support workpiece whenever
f
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.
Position the cord clear of the spinning accesso-
f
ry. If you lose control of the power tool, the cord
may be cut or snagged and your hand or arm may
be pulled into the spinning accessory.
Never lay the power tool down until the acces-
f
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the power
tool out of your control.
After changing the bits or making any adjust-
f
ments, make sure the collet nut, chuck or any
other adjustment devices are securely tight-
ened. Loose adjustment devices can unexpectedly
shift, causing loss of control, loose rotating compo-
nents will be violently thrown.
Do not run the power tool while carrying it at
f
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the ac-
cessory into your body.
Regularly clean the power tool's air vents. The
f
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
Do not operate the power tool near flammable
f
materials. Sparks could ignite these materials.
Do not use accessories that require liquid cool-
f
ants. Using water or other liquid coolants may re-
sult in electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or
f
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.
Maintain a firm grip on the power tool and po-
f
sition your body and arm to allow you to resist
kickback forces. The operator can control kick-
