Protection Guard for Cutting
For cutting metal, always work with the pro-
tection guard for cutting 7.
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 16.
The protection guard for cutting 7 is mounted in
the same manner as the protection guard for
sanding 6.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 4.
Screw the auxiliary handle 4 on the right or left
of the machine head depending on the working
method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle reduc-
es the vibrations, making operation more com-
fortable and secure.
Do not make any alterations to the auxiliary
handle.
Do not continue to use an auxiliary handle if it
is damaged.
Hand Guard
For operations with the rubber sanding
plate 12 or with the cup brush/wheel
brush/flap disc, always mount the hand
guard 11.
The hand guard 11 is fastened with the auxiliary
handle 4.
Mounting the Grinding Tools
Before any work on the machine itself, pull
the mains plug.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Clean the grinder spindle 5 and all parts to be
mounted.

For clamping and loosening the grinding tools,
lock the grinder spindle with the spindle lock
button 2.
Actuate the spindle lock button only when
the grinder spindle is at a standstill. Other-
wise, the machine may become damaged.
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding
tools. The mounting hole diameter must fit the
mounting flange without play. Do not use reduc-
ers or adapters.
When using diamond cutting discs, pay atten-
tion that the direction-of-rotation arrow on the
diamond cutting disc and the direction of rota-
tion of the machine (see direction-of-rotation ar-
row on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on
the clamping nut 10 and tighten with the two-
hole spanner.
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn free-
ly. Make sure that the grinding tool does
not graze against the protection guard or
other parts.
Flap Disc
For operations with the flap disc, always
mount the hand guard 11.
Rubber Sanding Plate
For operations with the rubber sanding
plate 12, always mount the hand guard 11.
See graphics page for the mounting sequence.
Screw on the round nut 14 and tighten with the
two-pin spanner.
Cup Brush/Disc Brush
For operations with the cup brush/wheel
brush, always mount the hand guard 11.
See graphics page for the mounting sequence.
The cup brush/disc brush must be able to be
screwed onto the grinder spindle until it rests
firmly against the grinder spindle flange at the end
of the grinder spindle threads. Tighten the cup
brush/disc brush with an open-end spanner.
