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.
f 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.
f Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting ac-
cessory may contact hidden wiring or its own cord. Cut-
ting accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the op-
erator an electric shock.
f 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.
f 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.
f 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.
f 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.
f Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
f 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
f
Kickback is a sudden reaction to a pinched or snagged ro-
tating 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 accesso-
ry’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 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.
f Maintain a firm grip on the power tool and position your
body and arm to allow you to resist kickback forces. Al-
ways 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.
f Never place your hand near the rotating accessory. Ac-
cessory may kickback over your hand.
f 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.
f 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.
f 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
f
Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when select-
ing sanding paper. Larger sanding paper extending be-
yond the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc, or kickback.
Safety warnings specific for polishing operations
f
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
workpiece.
Safety warnings specific for wire brushing operations
f
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.
f 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
Wear safety goggles.
f Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property damage or
may cause an electric shock.
f Release the On/Off switch and set it to the off position
when the power supply is interrupted, e. g., in case of a
