Regularly clean the power tool's air vents. The
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
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 accessory. Pinching or snagging causes rapid
stalling of the rotating accessory which in turn causes
the uncontrolled power tool to be forced in the direc-
tion 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 sur-
face 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 the 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 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 reac-
tion 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.
The accessory may kickback over your hand.
Do not position your body in the area where power
tool will move if kickback occurs. Kickback will pro-
pel the tool in the 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 acces-
sory. Corners, sharp edges or bouncing have a ten-
dency 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.
Safety warnings specific for sanding
operations
When sanding, do not use excessively oversized
sanding disc paper. Follow the manufacturers' rec-
ommendations when selecting sanding paper.
Larger sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.

operations
Safety warnings specific for wire brushing
operations

Additional safety warnings

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.
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 cen-
trifugal forces.
Make sure that the application tools are mounted in
accordance 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 opera-
tion and cause injuries.
Do not work materials containing asbestos. Asbes-
tos is considered carcinogenic.
Use a stationary extraction system, blow out venti-
lation slots frequently and connect a residual cur-
rent device (RCD) on the line side. When working
metal under extreme operating conditions, it is pos-
sible for conductive dust to settle in the interior of the
power tool. The total insulation of the power tool can
be impaired.
Do not rivet or screw any name-plates or signs onto
the power tool. If the insulation is damaged, protec-
tion against an electric shock will be ineffective.
Adhesive labels are recommended.
Always work using the auxiliary handle. The auxil-
iary handle ensures reliable guidance of the power
tool.
Before putting into operation, check the mains con-
nection and the mains plug for damage.
Use only original Würth parts and accessories.
