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 nor-
mally break apart during this test time.
Wear personal protective equipment. Depending on appli-
cation, 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 expo-
sure to high intensity noise may cause hearing loss.
Keep bystanders a safe distance away from work area. Any-
one entering the work area must wear personal protective
equipment. Fragments of workpiece or of a broken acces-
sory may fly 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 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
spinning 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.
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 accu-
mulation of powdered metal may cause electrical haz-
ards.
Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
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 acces-
sory. 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 mate-
rial 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 incor-
rect operating procedures or conditions and can be
avoided 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. 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.
Never place your hand near the rotating accessory. Acces-
sory may kickback over your hand.
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.
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 over the power tool.
Safety warnings specific for sanding operations
Do not use excessively oversized sanding disc paper. Follow
manufacturers recommendations, when selecting sanding
paper. Larger sanding paper extending beyond the sand-
ing pad presents a laceration hazard and may cause snag-
ging, tearing of the disc, or kickback.
Safety Warnings specific for Polishing operations
Do not allow any loose portion of the polishing bonnet or its
attachment strings to spin freely. Tuck away or trim any
loose attachment strings. Loose and spinning attachment
strings can entangle your fingers or snag on the work-
piece.
Safety warnings specific for wire brushing
operations
Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires by
applying excessive load to the brush. The wire bristles can
easily penetrate light clothing and/or skin.
If the use of a guard is recommended for wire brushing, do
not allow any interference of the wire wheel or brush with
the guard. Wire wheel or brush may expand in diameter
due to work load and centrifugal forces.
Additional safety warnings
Make sure that the application tools are mounted in accord-
ance with the manufacturers instructions. The mounted
application tools must be able to rotate freely. Incorrectly
mounted application tools can become loose during
operation and be thrown from the machine.
When using application tools with a threaded insert, take
care that the thread in the application tool is long enough
to hold the spindle length of the power tool. The thread in
the application tool must match the thread on the spindle.
Incorrectly mounted application tools can loosen during
operation and cause injuries.
Do not machine any material containing asbestos. Asbestos
is cancerogenic.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection against
an electric shock will be ineffective. Adhesive labels are
recommended.
