en ENGLISH
Continuous operation:
Switching on: Slide the lock (1) in the direction of the
arrow, press the trigger switch (2) and keep
it pressed. The machine is now switched on.
Now slide the lock (1) in the direction of the
arrow once more to lock the trigger switch (2)
(continuous operation).
Switching off: Press the trigger switch (2) and
release.
7.2 Working With the Wall Chaser
Always guide the machine with both hands on
the handles (12) and (13).
On the guard there are markings (6). The markings
are in the extension of the rear diamond cutting disc
and serve - when cutting grooves - as cutting
indicator.
Place the wall chaser (with the motor switched on)
with the support wheels (9) on the surface into
which a groove is to be cut, and slowly guide down
until the set cutting depth has been reached.
Then push the machine in cutting direction
Once the groove is complete, switch off the
tool and hold it steady until the diamond cut-off
wheel comes to a stop. Never attempt to remove
the cutting disc from the cut while the wheel is
in motion otherwise kickback may occur.
Remove the machine from the cut. Put the machine
down on its side.
You can remove the remaining strip between the
two chases with the chase extraction chisel
provided.
Grooves of greater depth cannot be cut into
hard material (e.g. cement) in one movement.
8. Maintenance, Cleaning
Significantly reduced work progress and increased
feed force are signs for blunt diamond cut-off
wheels. Sharpen blunt diamond cut-off wheels by
carrying out short cuts into abrasive materials such
as sand-lime brick.
It is possible that particles deposit inside the power
tool during operation. This impairs the cooling of the
power tool.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner. Prior to this operation,
separate the power tool from the power source and
wear protective goggles and a dust mask.

Always push the machine in
the stipulated direction
through the material to be
processed! See arrow (11) on
the guard. The wheel may
bind, walk up or kickback if the
power tool is restarted in the
workpiece.

9. Overload protection

9.1 Safety clutch
There is an automatic safety coupling built-in to the
gears of the wall chaser. This protects the operator
from the high torque that may, for example, occur if
the diamond cut-off wheel is canted during work.
The safety coupling protects and at the same time
takes the strain off the motor and the gears of the
machine. When the safety coupling engages,
immediately switch the motor off (do not allow the
coupling to drag!),
9.2 Electronic overload indicator
The electronic signal indicator (5) is on
Load of the machine is too high! Reduce the
feed pressure until the electronic signal
indicator goes off.

10. Troubleshooting

The machine does not start. The
electronic signal indicator (5) flashes. The
restart protection is active. If the mains plug is
inserted with the machine switched on or if the
power supply is restored following an interruption,
the machine does not start up. Switch the machine
off and back on again.
