“Off”

 position. 

When switching off, the levelling unit is locked.



Do not leave the switched-on measuring tool unattended and switch the mea-
suring tool off after use. 

Other persons could be blinded by the laser beam.

To save energy, only switch the measuring tool on when you are using it.

Operation Modes (see figure A – C)

The measuring tool has three operating modes between which you can switch at any 
time:

After switching on, the measuring tool is in cross-line operating mode with automatic 
levelling.

To change the operating mode, press the operating mode button

Working with Automatic Levelling

Position the measuring tool on a level and firm support or mount it to the tripod 

11

.

Select one of the operating modes with automatic levelling.

After switching on, the levelling function automatically compensates irregularities 
within the self-levelling range of ± 4 °. The levelling is finished as soon as the laser 
beams do not move any more.

If automatic levelling is not possible, e.g. because the surface on which the measuring 
tool stands deviates by more than 4 ° from the horizontal plane, the laser switches off. 
If this is the case, set up the measuring tool in a level position and wait for the self-lev-
elling to take place.

In case of ground vibrations or position changes during operation, the measuring tool 
is automatically levelled in again. To avoid errors, check the position of the horizontal 
and vertical laser line with regard to the reference points upon re-levelling.

Operating Mode

Cross-line operation (with automatic levelling): Generates a horizontal 
and a vertical laser line.

Cross-line and plumb point operation (with automatic levelling): Gener-
ates a horizontal and two vertical laser lines and a downwards plumb 
point. The device projects the two vertical laser lines at a right angle to 
one another.

Cross-line operation (without automatic levelling): Generates a horizontal 
and a vertical laser line.
