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
10 and tighten it with the combination spanner 4, (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 8. If the O-ring is missing or
damaged, the mounting flange 8 must
be replaced before resuming opera-
tion.
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 the 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.
Quick-clamping Nut
For convenient changing of grinding tools without the use of
additional tools, you can use the quick-clamping nut 11 in-
stead of the clamping nut 10.
The quick-clamping nut 11 may be used only for grind-
ing 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 21.
