arbour holes that do not match the mounting
hardware of the power tool will run out of bal-
ance, vibrate excessively and may cause loss
of control.
- 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 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 ac-
cessories will normally break apart during this
test time.
- Wear personal protective equipment. Depend-
ing on application, use face shield, safety gog-
gles 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.
- 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 ac-
cessory may fl y away and cause injury beyond
immediate area of operation.
- 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 shock the operator.
- Position the cord clear of the spinning acces-
sory. If you lose control, 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-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
- 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.
- Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the hous-
ing and excessive accumulation of powdered
metal may cause electrical hazards.
- Do not operate the power tool near fl ammable
materials. Sparks could ignite these materi-
als.
- Do not use accessories that require liquid cool-
ants. 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.
- Maintain a fi rm grip on the power tool and po-
sition your body and arm to allow you to resist
kickback forces. Always use auxiliary handle,
if provided, for maximum control over kick-
back or torque reaction during start-up. The
operator can control torque reactions or kick-
back forces, if proper precautions are taken.
- Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
- Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite
to the wheel's movement at the point of snag-
ging.
- 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.
- Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
