Inserting/Replacing Diamand Cup
Wheels (see figure A)
Approved Grinding Tools
All diamond cup wheels mentioned in these op-
erating instructions can be used.
Observe the dimensions of the diamond cup
wheels. The mounting hole diameter must fit the
mounting flange without play. The mounting
hole of the diamond cup wheel may not be in-
creased. Do not use reducers or adapters.
The permissible speed [rpm] or the circumfer-
ential speed [m/s] of the diamond cup wheels
used must at least match the values given in the
table.
Therefore, observe the permissible rotational/
circumferential speed on the label of the dia-
mond cup wheel.

Inserting Diamand Cup Wheels
Select a suitable diamond cup wheel for the
material to be worked. Please also observe the
material information on the packaging of the
diamond cup wheel.
Clean the grinder spindle 9 and all parts to be
mounted.
Place the mounting flange 10 on the grinder
spindle 9 so that the centring collar faces away
from the machine. The mounting flange must
engage on the flats of the grinder spindle (anti-
twist protection).
An O-ring (plastic part) is in-
serted in the mounting flange
10 around the centring collar.
If the O-ring is missing or is
damaged, it must in all cases
be replaced (article number
1 600 210 039) before the
mounting flange 10 is mounted.
Place the diamond cup wheel 11 on the mount-
ing flange 10. Pay attention that the direction-of-
rotation arrow on the diamond cup wheel
agrees with the direction-of-rotation arrow on
the guard and extraction hood 1.
Press the spindle lock button 3 to lock the grind-
ing spindle.
Screw on the clamping nut 12 and tighten it with
the two-pin spanner 14.
Pay attention that the collar of the clamping nut
12 faces away from the machine, as shown in
the figure.
After mounting the diamond cup wheel and
before switching on, check that the diamond
cup wheel is correctly mounted and that it
can turn freely. Make sure that the diamond
cup wheel does not graze against the guard
and extraction hood or other parts.
