Assembly
Mounting the Protective Devices
 Before any work on the machine itself, pull the mains
plug.
Note: After breakage of the grinding disc during operation or
damage to the holding fixtures on the protection guard/power
tool, the machine must promptly be sent to an after-sales ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
Protection Guard for Grinding
Place the protection guard 7 on the spindle collar. Adapt the
position of the protection guard 7 to the requirements of the
work step. Lock protection guard 7 by tightening locking
screw 8 with combination spanner 4/5.
 Adjust the protection guard 7 in such a manner that
sparking is prevented in the direction of the operator.
Note: The encoding keys on the protection guard 7 ensure
that only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 14.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 14 is mounted in the same
manner as the protection guard for grinding 7.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 3.
Screw the auxiliary handle 3 on the right or left of the machine
head depending on the working method.
Hand Guard
 For operations with the rubber sanding plate 17 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 16.
The hand guard 16 is fastened with the auxiliary handle 3.
Mounting the Grinding Tools
 Before any work on the machine itself, pull the mains
plug.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 6 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 1.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come 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 reducers or adapters.
When using diamond cutting discs, pay attention that the di-
rection-of-rotation arrow on the diamond cutting disc and the
direction of rotation of the machine (see direction-of-rotation
arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping nut
11 and tighten it with the combination spanner 4/5, (see sec-
tion "Quick-clamping Nut").
 After mounting the grinding tool and before switching
on, check that the grinding tool is correctly mounted
and that it can turn freely. Make sure that the grinding
tool does not graze against the protection guard or oth-
er parts.
Mounting flange for grinding spindle
M 14: A plastic part (O-ring) is fitted
around the centring collar of mounting
flange 9. If the O-ring is missing or
damaged, the mounting flange 9 must
be replaced before resuming opera-
tion.
Mounting flange for grinding spindle
M 10: The mounting flange can be used
on both sides.
Flap Disc
 For operations with the flap disc, always mount the
hand guard 16.
Rubber Sanding Plate
 For operations with the rubber sanding plate 17, al-
ways mount the hand guard 16.
See graphics page for the mounting sequence.
Screw on round nut 19 and tighten it with the combination
spanner 4/5.
Cup Brush/Disc Brush
 For operations with the cup brush/wheel brush, always
mount the hand guard 16.
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. Tight-
en the cup brush/disc brush with an open-end spanner.
Quick-clamping Nut
For convenient changing of grinding tools without the use of
additional tools, you can use the quick-clamping nut 12 in-
stead of the clamping nut 11.
 The quick-clamping nut 12 may be used only for grind-
ing or cutting discs.
Use only a flawless, undamaged quick-clamping nut 12.
When screwing on, pay attention that the side of the
quick-clamping nut 12 with printing does not face the
grinding disc; the arrow must point to the index mark 23.
