clamping nut, firmly turn
the grinding disc in clock-
wise direction.
A properly attached,
undamaged quick-clamp-
ing nut can be loosened
by hand when turning the
knurled ring in anticlock-
wise direction.
Never loosen a tight
quick-clamping nut
with pliers. Always use
the two-pin spanner.
Insert the two-pin spanner
as shown in the illustra-
tion.
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
12
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
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.
