during start-up. The operator can control torque reac-
tions or kickback forces, if proper precautions are taken.
Never place your hand near the rotating accessory.
u
Accessory may kickback over your hand.
Do not position your body in the area where power
u
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
u
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
u
toothed saw blade. Such blades create frequent kick-
back and loss of control.
Safety Warnings specific for Grinding operations
Use only wheel types that are recommended for your
u
power tool and the specific guard designed for the se-
lected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
The grinding surface of centre depressed wheels must
u
be mounted below the plane of the guard lip. An im-
properly mounted wheel that projects through the plane
of the guard lip cannot be adequately protected.
Wheels must be used only for recommended applica-
u
tions. For example: do not grind with the side of cut-
off wheel. Abrasive cut-off wheels are intended for peri-
pheral grinding, side forces applied to these wheels may
cause them to shatter.
Always use undamaged wheel flanges that are of cor-
u
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the pos-
sibility of wheel breakage. Flanges for cut-off wheels may
be different from grinding wheel flanges.
Do not use worn down wheels from larger power
u
tools. Wheel intended for larger power tool is not suit-
able for the higher speed of a smaller tool and may burst.
Safety Warnings specific for Polishing operations
Do not allow any loose portion of the polishing bonnet
u
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
Be aware that wire bristles are thrown by the brush
u
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 brush-
u
ing, 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 information
Wear safety goggles.
Use suitable detectors to determine if utility lines are
u
hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
Release the On/Off switch and set it to the off position
u
when the power supply is interrupted, e. g., in case of
a power failure or when the mains plug is pulled. This
prevents uncontrolled restarting.
Do not touch grinding discs until they have cooled
u
down. The discs can become very hot while working.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
