Protection Guard for Cutting
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 13.
Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting
13
is mounted in the same
manner as the protection guard for grinding
12
.
Extraction Hood for Sanding
The extraction hood
7
can be used for low-dust sanding of
paint, varnish and plastics in conjunction with the carbide
grinding head
9
or the rubber sanding plate
16
with a sanding
sheet
17
. The extraction hood
7
is not suitable for working
metals.
A suitable Bosch vacuum cleaner can be connected to the ex-
traction hood
7
.
The extraction hood
7
is mounted in the same manner as the
protection guard
12
. The brush collar is exchangeable.
Auxiliary Handle
Operate your machine only with the auxiliary handle 5.
Screw the auxiliary handle
5
on the right or left of the machine
head depending on the working method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle reduces the vibra-
tions, making operation more comfortable and secure.
Do not make any alterations to the auxiliary handle.
Do not continue to use an auxiliary handle if it is damaged.
Hand Guard
For operations with the rubber sanding plate 16 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 15.
The hand guard
15
is fastened with the auxiliary handle
5
.
Mounting the Grinding Tools
Before any work on the machine itself, pull the mains
plug.
Do not touch grinding and cutting discs before they
have cooled down.
The discs can become very hot while
working.
Clean the grinder spindle
6
and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button
2
.
Actuate the spindle lock button only when the grinder
spindle is at a standstill.
Otherwise, the machine may be-
come damaged.
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
10
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
8
.
If the O-ring is missing or damaged,
the mounting flange
8
must be replaced
before resuming operation.
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 with the two-pin span-
ner.
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 22.
