Starting Current Limiting
As a result of soft starting, a 13-A fuse is ade-
quate.
Constant Electronics
The constant speed electronics hold the speed at
no-load and when under load nearly constant and
ensure uniform working performance.

Overload Protection

When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately and
allow to cool for approx. 30 seconds at the high-
est no-load speed.
Restarting Protection
Prevents uncontrolled restarting of the machine
after an interruption in the mains supply.
The mains supply remains interrupted and the
service indicator 9 lights up.
Restarting operation:
switch 8 to the Off position and start the machine
again.
Operating Instructions
Wear protective goggles, ear protection
and a dust protection mask.
Wear protective gloves and sturdy shoes.
The machine may only be used for dry ma-
chining of masonry.
Pre-select the cutting depth, as described in the
same-named section.
Note: To compensate inaccuracies that occur
when breaking away the fins, the cutting depth
must be set approx. 3 mm deeper than the re-
quired slot depth.
Place the machine with the chaser rollers 6 on
the surface to be worked. The cutting unit must
be in the uppermost position.
Switch the machine on.
Press the release button 2 upwards to release
the cutting unit. Slowly lower and plunge the cut-
ting unit into the material.
Always guide the machine with both handles.
Important is the direction in which cutting is per-
formed.
The machine must always work opposite to the
direction of rotation. Therefore, never move the
machine in the other direction! Otherwise, the
danger exists of it being pushed uncontrolled
out of the cut.
The machine can be both pushed or pulled in the
cutting direction. Vertical slots can easily be cut
by pulling the machine from top to bottom.
After finishing the working procedure, swivel the
cutting unit out of the slot with the machine still
running, until the cutting unit engages in the up-
permost position.
Switch the On/Off
Switch the machine off.
Do not brake coasting cutting disks with side
pressure.
Remove the remaining fin of the material with the
break-out tool 17, included in the delivery.
Curved cuts are not possible, as the diamond cut-
ting discs could jam in the material.
When cutting through plate materials, ensure that
the materials are firmly backed on a surface or
supported.
When breaking through walls, e. g. with a rotary
hammer, the chipping off of the surface material
can be widely avoided when a slot with maximum
cutting depth is cut in first.
English - 6
Work with moderate
feed, suited to the ma-
terial being worked,
while paying attention
to the cutting direction!
Caution! Diamond cutting discs become
very hot during operation; do not touch
them before they have cooled down.
