Setting cutting depth
After undoing the clamping lever (4) you can set the
desired cutting depth using the scale (3).
Retighten the clamping lever (4).
Note: If required, the position / the clamping force of
the clamping lever (4) must be changed. To do this,
pull out the lever a bit, turn the lever and lower again
(Fig. 1).

Attaching the dust extraction
Caution! Never work without a dust extraction
device. Dusts can be harmful to health!
Never work without a dust extraction device.
The motor can quickly choke on stone dust.
Use a suitable HiKOKI (L-class and over) vacuum
cleaner.
To extract the stone dust generated when working
with the wall chaser, put the suction hose onto the
extraction nozzle (8).

Switching on and off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand
securely and concentrate.
Avoid the machine swirling up or taking in dust
and chips. After switching off the machine,
only place it down when the motor has come to a
standstill.
Torque activation:
Switching on: Slide the lock (1) in the direction of the
arrow and press the trigger switch (2).
Switching off: release the trigger switch (2).
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.

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
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.
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.
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.
Overload protection
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!),

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.
