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 direction-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 10 and tighten with the two-pin spanner;
see Section "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 other
parts.
An O-ring (plastic part) is inserted in
the mounting flange 8 around the
centring collar. If the O-ring is
missing or is damaged, it must in
all cases be replaced before the
mounting flange 8 is mounted.

Quick-clamping Nut

For convenient changing of grinding tools without the
use of additional tools, you can use the quick-clamping
nut 11 instead of the clamping nut 10.
The quick-clamping nut 11 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamping
nut 11.
When screwing on, pay attention that the side of
the quick-clamping nut 11 with printing does not
face the grinding disc; the arrow must point to
the index mark 22.
