Do not continue to use the power tool when the damp-
ing element is damaged.
Hand Guard
For operations with the rubber sanding plate 19 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 17.
The hand guard 17 is fastened with the auxiliary handle 4.
Mounting the Grinding Tools
Before any work on the machine itself, pull the mains
plug.
Grinding and cutting discs become very hot while
working; do not touch until they have cooled.
Note for GWS 24-230 VX/GWS 24-230 JVX: It is recom-
mended to use the quick-clamping nut 13. When using clamp-
ing nut 12, an increased expenditure of force must be taken
into account when loosening the clamping nut.
Clean the grinder spindle 5 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 1.
Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
Quick-clamping Nut
With the quick-clamping nut 13, grinding tools can be mount-
ed without additional tools.
Use only a flawless, undamaged quick-clamping nut 13.
When screwing on, pay attention that the side of the
quick-clamping nut 13 with printing does not face the
grinding disc; the arrow must point to the index mark 26.
Lock the grinder spindle with
the spindle lock button 1. To
26
tighten the quick-clamping
nut, firmly turn the grinding
disc in clockwise direction.
A properly attached, undam-
aged quick-clamping nut can
be loosened by hand when
turning the knurled ring in an-
ticlockwise direction.
Never loosen a tight quick-
clamping nut with pliers. Al-
ways use the two-pin span-
ner. Insert the two-pin span-
ner as shown in the
illustration.
Bosch Power Tools
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 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
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 oth-
er parts.
A plastic part (O-ring) is fitted around
the centring collar of mounting flange
10. If the O-ring is missing or dam-
aged, the mounting flange 10 must be
replaced before resuming operation.
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, al-
ways mount the hand guard 17.
See graphics page for the mounting sequence.
3 601 H55.../3 601 H56...: Before mounting the rubber
sanding plate 19, put the 2 spacer discs 18 onto the grinder

Screw on the round nut 21 and tighten with the two-pin span-
ner.
Note for GWS 24-230 VX/GWS 24-230 JVX: When loosen-
ing the round nut 21, an increased expenditure of force must
be taken into account.
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. Tight-
en the cup brush/disc brush with an open-end spanner.
Note for GWS 24-230 VX/GWS 24-230 JVX: When loosen-
ing the grinding tool, an increased expenditure of force must
be taken into account.
