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 re-
quirements of the work step. Lock
protection guard 7 by tightening
locking screw 8 with combination
spanner 4.
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 13.
Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 13 is mounted in the same
manner as the protection guard for grinding 7.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 20 is
mounted in the same manner as the protection guard for
grinding 7.
Auxiliary Handle
Operate your machine only with the auxiliary handle 5.
Screw the auxiliary handle 5 on the right or left of the machine
head depending on the working method.
Hand Guard
For operations with the rubber sanding plate 16 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 15.
The hand guard 15 is fastened with the auxiliary handle 5.

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.
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.
Flap Disc
For operations with the flap disc, always mount the
hand guard 15.
Rubber Sanding Plate
For operations with the rubber sanding plate 16, al-
ways mount the hand guard 15.
See graphics page for the mounting sequence.
Screw on round nut 18 and tighten it with the combination
spanner 4.
Cup Brush/Disc Brush
For operations with the cup brush/wheel brush, always
mount the hand guard 15.
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.
Approved Grinding Tools
All grinding tools mentioned in these operating instructions
can be used.
