Changing the Tool
Before any work on the machine itself, pull
the power plug.
Wear protective gloves.
Use only diamond cutting discs suitable for
dry cutting of the material with an allowable
speed that is at least as high as the no-load
speed of the machine.
Lay the machine on the side so that the cutting
depth scale 2 is visible.
Loosen the pre-selection cutting depth clamping
lever for 15 and pre-select the lowest/least cut-
ting depth.
Removing the Clamping Assembly
With the spindle locking button 13 , lock the
grinder spindle (only when the grinder spindle is
at a standstill!).
Loosen the clamping nut 5 using the two-pin
spanner 19 and unscrew it. Remove the spacer
discs 6 and the mounting flange and clean the
clamping parts.
Determining the Slot Width
The slot width results from the amount of spacer
discs between the two diamond cutting discs 7
and the cutting width of the diamond cutting
discs.
The slot width is calculated as follows:
Slot width = Thickness of the spacer discs +
width of the diamond cutting discs (4 mm).
The allowable slot width is shown in the section
"Tool Specifications".
The machine may only be operated with one or
two diamond cutting discs.
Mounting the Clamping Assembly
Set the mounting flange 8 onto the grinder spin-
dle 9. The mounting flange 8 with its driving fea-
ture must be properly seated on the tool spindle.
Place the diamond cutting disc 7 and the spacer
discs 6 on the mounting flange 8.
Regardless of the required slot width, all spacer
discs 6 included in the delivery must be mounted.
At least one spacer disc 6 must be mounted be-
tween two diamond cutting discs 7.
When assembling the diamond cutting discs, en-
sure that the direction-of-rotation arrows on the
diamond cutting discs match with the direction-of-
rotation arrow on the housing.

With the spindle locking button 13, lock the
grinder spindle (only when the grinder spindle is
at a standstill!).
Screw on the clamping nut 5 and tighten with the
two-pin spanner 19.
Cutting Depth Pre-selection
Loosen the clamping lever for cutting depth
pre-selection 15 and adjust the required cutting
depth according to the cutting depth scale 2.
Tighten the clamping lever for cutting depth
pre-selection 15 again.
Dust Extraction
Insert the extraction elbow 16 into the protective
cover fixture and connect the vacuum hose (ac-
cessory).
In case of a malfunction of the dust extraction
system, stop working, switch the machine off
and correct the malfunction of the dust ex-
traction system.
The machine can be plugged directly into the re-
ceptacle of a Bosch general-purpose vac with re-
mote starting control. The vac starts automati-
cally as soon as the machine is switched on.
The vacuum cleaner must be suitable for the ma-
terial to be worked on.
Use a special vacuum cleaner when vacuuming
dry dust that is especially detrimental to health
and possibly carcinogenic.

When working with 2 diamond cutting discs
always replace them in pairs.
The mounted diamond discs protrude out
of the protective cover even at the lowest
pre-selected cutting depth. Therefore,
never set down the machine on the on the
chaser rollers 10, but lay it on the side.
Before any work on the machine itself, pull
the power plug.
The dust generated during working can be
detrimental to health, inflammable or ex-
plosive. Suitable safety measures are re-
quired.
For example: Some types of dust are sus-
pected of being carcinogenic. Use suitable
dust-/chip extraction and wear a dust
mask.
The vacuum cleaner must be approved for
the vacuuming of masonry dust.
