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
pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or condi-
tions and can be avoided by taking proper pre-
cautions as given below.
 Maintain a firm grip on the power tool and po-
sition your body and arm to allow you to resist
kickback forces. Always use auxiliary handle,
if provided, for maximum control over kick-
back or torque reaction during start-up. The
operator can control torque reactions or kick-
back forces, if proper precautions are taken.
 Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
 Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back 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 fre-
quent kickback and loss of control.
Additional safety instructions for grinding
 Use only wheel types that are recommended
for your power tool and the specific guard de-
signed for the selected wheel. Wheels for
which the power tool was not designed cannot
be adequately guarded and are unsafe.
 The grinding surface of the centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip can-
not be adequately protected.
 The guard must be securely attached to the
power tool and positioned for maximum safe-
ty, so the least amount of wheel is exposed to-
wards the operator. The guard helps to protect
operator from broken wheel fragments, acciden-
tal contact with wheel and sparks that could ig-
nite clothing.
 Wheels must be used only for recommended
applications. For example: do not grind with
the side of the cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding; side
forces applied to these wheels may cause them
to shatter.

 Always use undamaged wheel flanges that are
of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel flanges.
 Do not use worn down wheels from larger
power tools. Wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
Additional safety warnings
Wear safety goggles.
 Use suitable detectors to determine if utility
lines are hidden in the work area or call the lo-
cal utility company for assistance. Contact with
electric lines can lead to fire and electric shock.
Damaging a gas line can lead to explosion. Pen-
etrating a water line causes property damage or
may cause an electric shock.
 Release the On/Off switch and set it to the off
position 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.
 When working stone, use dust extraction. The
vacuum cleaner must be approved for the ex-
traction of stone dust. Using this equipment re-
duces dust-related hazards.
 Do not touch abrasive wheels until they have
cooled down. The discs can become very hot
while working.
 When working with the machine, always hold
it firmly with both hands and provide for a se-
cure stance. The power tool is guided more se-
cure with both hands.
 Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
Products sold in GB only: Your product is fitted
with an BS 1363/A approved electric plug with in-
ternal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it
should be cut off and an appropriate plug fitted in
its place by an authorised customer service agent.
The replacement plug should have the same fuse
rating as the original plug.
The severed plug must be disposed of to avoid a
possible shock hazard and should never be insert-
ed into a mains socket elsewhere.
Safety Warnings for Diamond Cup Wheels
 Work only with the fitting extraction hood of
the power tool being used, connected to a
suitable vacuum cleaner.
