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 (article
number 1 600 210 039) before
the mounting flange 8 is mounted.
Flap Disc
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 15.
Rubber Sanding Plate
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 15.
See graphics page for the mounting sequence.
Screw on the round nut 18 and tighten with the two-
pin spanner.
Cup Brush/Disc Brush
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, 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. Tighten 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-clamp-
ing 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-clamp-
ing 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.
