Initial Operation
Always use the correct voltage: The voltage of
the power source must agree with the values on
the nameplate of the machine.
Before switching the machine on, set
down the machine on the two rear
chaser rollers 10 in such a manner that
the diamond cutting discs do not touch
the workpiece.
Switching On and Off
To start the machine, press the On/Off switch 1
forward and then down.
To lock on, push the pressed On/Off switch 1
further forwards.
To switch the unit off, release the On/Off
switch 1 or press and then release it.
Switch configuration without lock
(specific countries):
To start the unit, press the On/Off switch 1 and
keep it pressed.
To switch off the unit, release the On/Off
switch 1.
Never set down the rotating machine on
the chaser rollers 10, moreover lay it on the
side so that the cutting discs can run freely
and do not point toward the body.
Check the diamond cutting discs before
use. The diamond cutting discs must be
mounted in exact alignment and be able to
rotate freely. Carry out a test run for at least
30 seconds without any load. Do not use
any diamond cutting discs that are dam-
aged, out-of-balance, or vibrate.
Starting Current Limiting
As a result of controlled starting of the machine,
a 16 A fuse is adequate.
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.
Restarting operation:
switch 1 to the Off position and start the machine
again.

Operating Instructions
Pre-select the cutting depth, as described in the
same-named section.
Note: To compensate inaccuracies that occur
when breaking away the fin, the cutting depth
must be set approx. 3 mm deeper than the de-
sired slot depth.
Always guide the machine with both handles.
Do not guide or carry the machine by the ex-
traction elbow.
The cutting direction is very important.
The machine must always work opposite to the
direction of rotation. Therefore, never move the
machine in the other direction! Otherwise, there
is the danger of it being pushed uncontrolled out
of the cut.
At the end of the work cycle, pivot the running di-
amond cutting discs out of the groove and switch
the machine off.
Do not brake cutting discs that are slowing down
to a stop by using side pressure.

The machine may only be used for dry ma-
chining of masonry.
Set down the machine on the two rear chaser
rollers 10 in such a manner that the diamond
cutting discs do not touch the workpiece.
Switch the machine on, slowly lower it and
plunge into the material.
Work with moderate feed, suited to the mate-
rial being worked, while paying attention to
the cutting direction!
