Assembly

Inserting/Replacing the Batteries

Alkali-manganese batteries are recommended for the 
measuring tool.

To open the battery lid 

6

, press on the latch 

7

 and fold the 

battery lid up. Insert the batteries. When inserting, pay 
attention to the correct polarity according to the repre-
sentation on the inside of the battery compartment.

When the battery indication 

8

 flashes, the batteries are 

weak. When the battery indication flashes for the first time, 
the measuring tool can still be operated for approx. 2 h.

When the battery indication 

8

 lights up constantly, meas-

uring is no longer possible. The measuring tool automati-
cally switches off after a short time.

Always replace all batteries at the same time. Only use 
batteries from one brand and with the identical capacity.



Remove the batteries from the measuring tool 
when not using it for extended periods. 

When stor-

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

Operation

Initial Operation



Protect the measuring tool against moisture and 
direct sun light.



Do not subject the measuring tool to extreme tem-
peratures or variations in temperature. 

As an exam-

ple, do not leave it in vehicles for a long time. In case of 
large variations in temperature, allow the measuring 
tool to adjust to the ambient temperature before put-
ting it into operation. In case of extreme temperatures 

or variations in temperature, the accuracy of the meas-
uring tool can be impaired.



Avoid hard knocks to the measuring tool or drop-
ping it. 

Damaging the measuring tool can cause accu-

racy to be compromised. Following a hard knock or 
fall, carry out a check by comparing the laser lines or 
plumb beams with a known horizontal or vertical refer-
ence line or verified perpendicular points.

Switching On and Off

To 

switch on

 the measuring tool, press the On/Off button 

3

 once briefly. Immediately after the switching on, the 

measuring tool projects the three laser lines 0 °, 45 ° and 
90 ° from the exit openings 

1

. Furthermore, the battery

indication 

8

 lights up for 3 s.



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.

When the On/Off button 

3

 is pressed a second time, the 

measuring tool switches over from 3-line operation to 
2-line operation: Only the 0 ° and the 90 ° laser lines are 
projected.

To 

switch off

 the measuring tool, press the On/Off button 

3

 a third time.

Deactivating the Automatic Shut-off

The measuring tool switches off automatically after an 
operating duration of 30 minutes.

To deactivate the automatic switch-off, press the On/Off 
button 

3

 for 3 s when you switch on the measuring tool. 

When the automatic switch-off is deactivated, the laser 
lines flash briefly to confirm after the switching on.



Do not leave the switched-on measuring tool unat-
tended and switch the measuring tool off after use. 

Other persons could be blinded by the laser beam.

1) The working range can be decreased by unfavourable environmental conditions (e. g. direct sun irradiation).

2) The angular accuracy between the 45 ° laser line and the 90 ° laser line is max. ± 0.4 mm/m.

The measuring tool can be clearly identified with the serial number
