Do not use a damaged accessory. Before each use in-
spect 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 in-
stall an undamaged accessory. After inspecting and in-
stalling 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 min-
ute. Damaged accessories will normally break apart during
this test time.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris gen-
erated 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 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.
Hold power tool only by the 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 ex-
posed metal parts of the power tool "live" and could give
the operator an electric shock.
Always hold the tool firmly in your hand(s) during the
start-up. The reaction torque of the motor, as it acceler-
ates to full speed, can cause the tool to twist.
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 work-
piece 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 accessory. 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 spin-
ning accessory.
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.
After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other adjust-
ment devices are securely tightened. Loose adjustment
devices can unexpectedly shift, causing loss of control,
loose rotating components will be violently thrown.
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 housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.
Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Us-
ing water or other liquid coolants may result in electrocu-
tion or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged ro-
tating 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 accesso-
ry'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 pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.
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 precau-
tions are taken.
Use special care when working corners, sharp edges,
etc. Avoid bouncing and snagging the accessory. Cor-
ners, sharp edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or kickback.
Do not use a toothed saw blade. Such blades create fre-
quent kickback and loss of control over the power tool.
Always feed the bit into the material in the same direc-
tion 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.
When using rotary files, 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 the rotary
file, high-speed cutter or tungsten carbide cutter grab, it
may jump from the groove and you could lose control of the
tool.
Safety warnings specific for grinding operations
Use only wheel types that are recommended for your
power tool and only for recommended applications.
For example: do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intended for peripheral
grinding, side forces applied to these wheels may cause
them to shatter.
