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 reduc-
ers or adapters.
When using diamond cutting discs, pay atten-
tion that the direction-of-rotation arrow on the
diamond cutting disc and the direction of rota-
tion of the machine (see direction-of-rotation ar-
row on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on
the clamping nut 9 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 free-
ly. Make sure that the grinding tool does
not graze against the protection guard or
other parts.
An O-ring (plastic part) is in-
serted in the mounting flange 7
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 7 is mounted.
Flap Disc
For operations with the flap disc, always
mount the hand guard 17.
Rubber Sanding Plate
For operations with the rubber sanding
plate 19, always mount the hand guard 17.
See graphics page for the mounting sequence.
Before mounting the rubber sanding plate 19,
put the 2 spacer discs 18 onto the grinder spin-
dle 4.
Screw on the round nut 21 and tighten with the
two-pin spanner.
Bosch Power Tools
Cup Brush/Disc Brush
For operations with the cup brush/wheel
brush, always mount the hand guard 17.
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.
Grinding Cup
When working with the grinding cup, mount
the special protection guard 14.
The grinding cup 15 should never project further
out of the protection guard 14 than necessary
for the respective grinding application. Adjust
the protection guard 14 accordingly to this di-
mension.
See graphics page for the mounting sequence.
Screw on the clamping nut 9 and tighten it with
the two-pin spanner 16.
Quick-clamping Nut
For convenient changing of grinding tools with-
out the use of additional tools, you can use the
quick-clamping nut 10 instead of the clamping
nut 9.
The quick-clamping nut 10 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 10.
When screwing on, pay attention that the side
of the quick-clamping nut 10 with printing
does not face the grinding disc; the arrow must
point to the index mark 26.
Lock the grinder spin-
dle with the spindle
26
lock button 1. To tight-
en the quick-clamping
nut, firmly turn the
grinding disc in clock-
wise direction.
