Swivelling Out the Cutting Unit
For a tool change, the cutting unit must be swiv-
elled out completely. Place the machine on a firm
surface. Turn the release lock
2
in anticlockwise di-
rection, using e. g. the spanner end of the two-pin
spanner
19
.
This releases the cutting unit and immediately
swivels it upwards by means of resiliance.
Dismounting the Clamping Assembly
(see figure A)
Press the spindle lock button
9
to lock the grinding
spindle.
Actuate the spindle lock button only when the
grinder spindle is at a standstill.
Otherwise, the
machine may become damaged.
Loosen the clamping nut
18
with the two-pin span-
ner
19
and unscrew the clamping nut
18
. Remove
the spacer discs
17
and the mounting flange
15
.
Clean the grinder spindle
14
and all parts to be
mounted.
Determining the Slot Width
The slot width results from the amount of spacer
discs
17
between the two diamond cutting discs
16
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.
The allowable slot width is shown in the section
“Technical Data”.
The machine can be operated with one or two dia-
mond cutting discs.
Mounting the Clamping Assembly (see figure A)
Set the mounting flange
15
onto the grinder spin-
dle
14
. The mounting flange with its driving feature
must be properly seated on the grinding spindle.
Place the diamond cutting disc
16
and the spacer
discs
17
on the mounting flange
15
.
Regardless of the requested slot width, all
spacer discs 17 provided must always be
mounted.
Otherwise, the diamond cutting disc
16
can become loose during operation and lead
to injuries.
Amount of required spacer discs:
3 pce. each 4 mm thick and 4 pce., each 6 mm
thick
At least one spacer disc
17
must be mounted be-
tween two diamond cutting discs
16
.
When mounting the diamond cutting discs, ensure
that the direction-of-rotation arrows on the dia-
mond cutting discs match with the rotation rotation
direction of the machine (see direction-of-rotation
arrow on the gear case).
Press the spindle lock button
9
to lock the grinding
spindle.
Screw on the clamping nut
18
and tighten it with
the two-pin spanner
19
.
Swivel the cutting unit back again. Check the lock-
ing system of the cutting unit by pulling the handle.
When working with 2 diamond cutting discs
16
, al-
ways replace them in pairs.
See graphics page for the mounting sequence.
Operation
Pre-selecting the Cutting Depth
The cutting depth may only be pre-selected
when the machine is switched off.
The requested cutting depth can be pre-selected
with the depth stop
6
.
Press the button for depth stop adjustment
5
and
push the depth stop
6
to the requested cutting
depth on the cutting-depth scale
4
. Release button
5
again.
Ensure that the depth stop
6
is engaged again.
Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Power tools marked with 230 V can also be op-
erated with 220 V.
Switching On and Off
Before starting the machine, check if the cut-
ting unit has engaged in the upper position.
Otherwise the diamond cutting discs can touch
the workpiece, resulting in possible loss of con-
trol over the power tool when switching on.
To
start
the power tool, push the On/Off switch
10
forwards.
To
lock
the On/Off switch
10
, press the On/Off
switch
10
down at the front until it latches.
To
switch off
the power tool, release the On/Off
switch
10
or, if it is locked, briefly push down the
back of the On/Off switch
10
and then release it.
To save energy, only switch the power tool on
when using it.
Check the diamond cutting discs before use.
The diamond cutting disc(s) must be mounted
properly and be able to rotate freely. Carry out
a test run for at least one minute without any
load. Do not use diamond cutting discs that
are damaged, out-of-balance, or vibrate.
Dam-
aged diamond cutting discs can rupture and
lead to injuries.
Reduced starting current
The electronic reduced starting current limits the
power consumption when switching the tool on
and enables operation from a 13 ampere fuse.
