Technical Data

Assembly

Inserting/Replacing the Batteries

Alkali-manganese batteries are recommended for the meas-
uring 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 

extended periods, the batteries can corrode and self-
discharge.

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 or falling of the measuring tool. 

Af-

ter heavy exterior impact on the measuring tool, an accura-
cy check should always be carried out before continuing to 
work (see “Levelling Accuracy”).



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 40 ° 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, 
either 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.
