 Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent 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 designed for the se-
lected wheel. Wheels for which the power tool was not de-
signed 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 cannot be adequately protected.
 The guard must be securely attached to the power tool
and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator. The
guard helps to protect operator from broken wheel frag-
ments, accidental contact with wheel and sparks that
could ignite clothing.
 Wheels must be used only for recommended applica-
tions. 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 cor-
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the possi-
bility of wheel breakage. Flanges for cut-off wheels may be
different from grinding wheel flanges.
 Do not use worn down reinforced wheels from larger
power tools. Wheels intended for larger power tools are
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 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.
 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 pre-
vents uncontrolled restarting.
 When working stone, use dust extraction. The vacuum
cleaner must be approved for the extraction of stone
dust. Using this equipment reduces 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 secure stance. The
power tool is guided more secure with both hands.

 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
 Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal 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 inserted into a mains
socket elsewhere.
Products sold in AUS and NZ only: Use a residual current
device (RCD) with a rated residual current of 30 mA or
less.
Safety Warnings for Diamond Cup Wheels
 Work only with the fitting extraction hood of the power
tool being used, connected to a suitable vacuum clean-
er.
 Select a diamond cup wheel suitable for the material to
be worked. Observe the material information on the
packaging.
 Before assembling, clean the clamping set, spindle and
diamond cup wheel.
 Observe the dimensions of the diamond cup wheel. The
mounting hole diameter must fit the mounting flange.
Do not use reducers or adapters. The mounting hole of
the diamond cup wheel may not be enlarged.
 The allowable maximum speed of the diamond cup
wheel must correspond with the maximum speed of the
power tool.
 To prevent damage, dismount diamond cup wheels be-
fore transporting the power tool.
 In order to achieve maximal working results, apply only
low pressure when grinding; do not wedge, jam, jolt,
jerk or plunge.
 Diamond cup wheels can heat up considerably while
working; do not touch them before they have cooled
down.
 Do not place the power tool down until after the dia-
mond cup wheel has come to a complete stop.
 Use the two-pin spanner 3 607 950 017 to release and
tighten the clamping nut.
