• Firmly tighten the outer flange (15) using the
flange key (16).
• Release the spindle lock button (5).
• Mount the guard (6).
• Raise the base (7) and tighten the locking knob
(3).
• Firmly tighten the Allen screws (12) using the

4. OPERATION
Setting the slot width (fig. B E)
The slot width can be set using the spacers be-
tween the cutting discs. The number of spacers
between the cutting discs determine the slot width.
- Do not set the slot width during use.
- Always mount at least one spacer
between the cutting discs.
• Determine the slot width.
• Mount the spacers (18) around the cutting
discs (17 & 19) in the required order. Refer to
the chapter “Replacing the cutting discs”.
Setting the slot depth (fig. A & F)
The slot depth is variable between 5 and 40 mm.
The slot depth can be read from the scale (4).
Do not set the slot depth during use.
• Slacken the locking knob (3).
• Tilt the base (7) to the required position. Set
a slot depth approximately 3 mm deeper than
the required depth to compensate for possible
unevenness of the wall surface.
• Tighten the locking knob (3).
Switching on and off (fig. A)
• To switch on the machine, keep the lock-off but-
ton (2) pressed and simultaneously press the
on/off switch (1).
• To switch off the machine, release the on/off
switch (1).
Overload protection
The machine is equipped with an overload protec-
tion device which automatically switches off the
machine if the machine is overloaded.
• Switch off the machine.
• Remove the machine from the workpiece.
• Switch on the machine.
• Run the machine at no-load for approximately
1 minute to allow the machine to cool down.
Dust extraction (fig. G)
Only use the machine when it is connected to a
vacuum device which is approved for stone dust.
The vacuum device must be suitable for the material
to be worked. Use a special vacuum device when
working with toxic materials or where toxic dust is
produced.
- Never use a household vacuum cleaner.
The use of a household vacuum cleaner
can easily damage both your health
and the vacuum cleaner.
- Always use the dust extraction adapter.
- Make sure that the hose of the vacuum
device is securely connected to the
dust extraction adapter.
- If the vacuum device breaks down, stop
work immediately, switch off the
machine, remove the mains plug from
the mains, and try to solve the problem.
• Insert the dust extraction adapter (22) into the
dust extraction connection (9).
• Connect the hose of a vacuum device to the
dust extraction adapter (22).
Hints for optimum use
• Draw lines to define the direction in which to
guide the cutting discs.
• Hold the machine with both hands. Keep your
second hand on the auxiliary grip (11).
• Set the slot width.
• Take one of the following steps:
- Lower the machine into the wall and set the
slot depth (recommended). The machine is
placed against the wall and the cutting discs
lower into the wall in order to set the slot
depth more accurately.
- Set the slot depth and lower the machine
into the wall.
• Place the machine with the guide roller (8) on
the wall. Make sure that the cutting discs align
with the drawn lines on the wall.
• Set the slot depth.
• Switch on the machine.
