Assembly
Inserting/Replacing the Batteries
Alkali-manganese batteries are recommended for the mea-
suring tool.
To open the battery lid 10, slide the latch 11 in the direction 
of the arrow and fold the battery lid up. Insert the batteries. 
When inserting, pay attention to the correct polarity accord-
ing to the representation on the inside of the battery lid.
When the batteries become weak, a single 5 s audio signal will 
sound. The battery low indicator 2 continuously flashes red. 
The measuring tool can be operated for less then 2 h.
If the batteries are weak when switching on the measuring 
tool, the 5 s audio signal will sound directly after switching on 
the measuring tool.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
 Remove the batteries from the measuring tool when 
not using it for extended periods. When storing for ex-
tended periods, the batteries can corrode and self-dis-
charge.
Operation
Initial Operation
 Loud audio signals will sound under certain conditions 
while operating the measuring tool. Therefore, keep 
the measuring tool away from your ear or other per-
sons. 
The loud audio signal can cause hearing damage.
 Protect the measuring tool against moisture and direct 
sun light.
 Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do 
not leave it in vehicles for a long time. In case of large vari-
ations in temperature, allow the measuring tool to adjust to 
the ambient temperature before putting it into operation. 
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact to or falling down of the measuring 
tool. Damage to the measuring tool can impair its accura-
cy. After heavy impact or shock, compare the laser lines or 
plumb beams with a known horizontal or vertical reference 
line or with already checked plumb points.
 Switch the measuring tool off during transport. When 
switching off, the levelling unit, which can be damaged in 
case of intense movement, is locked.
Switching On and Off
To switch on the measuring tool, slide the On/Off switch 7 to 
the 
on” position (when working without automatic level-
ling) or to the 
on” position (when working with automat-
ic levelling). Immediately after switching on, the measuring 
tool sends laser beams out of the exit openings 1.
 Do not point the laser beam at persons or animals and 
do not look into the laser beam yourself, not even from 
a large distance.
 Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other 
persons could be blinded by the laser beam.
To switch off the measuring tool, slide the On/Off switch 7 to 
the “off” position. When switching off, the levelling unit is 
locked.
When exceeding the maximum permitted operating tempera-
ture of 45 °C, the measuring tool switches off to protect the 
laser diode. After cooling down, the measuring tool is ready 
for operation and can be switched on again.
Deactivating the Automatic Shut-off
When no button on the measuring tool is pressed for approx. 
30 minutes, the measuring tool automatically switches off to 
save the batteries.
To switch on the measuring tool after automatic shut-off, ei-
ther slide the On/Off switch 7 to the “off” position and then 
switch the measuring tool on again or press the operating 
mode button 5 once or press the pulse-function button 3 
once.
To deactivate the automatic shut-off, keep the operating 
mode button 5 pressed for at least 3 s (while the measuring 
tool is switched on). Deactivation of the automatic shut-off is 
confirmed by brief flashing of the laser beams.
To activate the automatic shut-off, switch the measuring tool 
off and then on again or press and hold the operating mode 
button 5 for at least 3 s.
Deactivating the Signal Tone
After the measuring tool has been switched on, the audio sig-
nal is always activated.
To deactivate/activate the audio signal, press and hold the 
operating mode button 5 and the pulse-function button 3 at 
the same time for at least 3 s.
The audio signal activation and deactivation are both con-
firmed by three short beeps.
Operating Modes
The measuring tool has three operating modes between 
which you can switch at any time:
– Horizontal operation: generates a horizontal laser plane,
– Vertical operation: generates a vertical laser plane,
– Cross-line operation: generates a horizontal and vertical 
laser plane.

1) The working range can be decreased by unfavourable environmental 
conditions (e.g. direct sun irradiation).
The measuring tool can be clearly identified with the serial number 13 
on the type plate.
