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.

Hand Guard



For operations with the rubber sanding plate 17 or with 
the cup brush/wheel brush/flap disc, always mount the 
hand guard 16.

The hand guard 

16

 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 16.

Rubber Sanding Plate



For operations with the rubber sanding plate 17, al-
ways mount the hand guard 16.

See graphics page for the mounting sequence.

Screw on the round nut 

19

 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 16.

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 25.

Lock the grinder spindle with 
the spindle lock button 

2

. To 

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.
