Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
To switch off the measuring tool, slide the on/off switch (2) to the Off position. The pen-
dulum unit is locked when the tool is switched off.
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be blinded by the laser beam.
Operating Modes
The measuring tool has three operating modes, which can be selected at any time:
Operating mode
Cross-line mode with automatic levelling (see figure A): The measuring tool
generates one horizontal and one vertical laser line.
Cross-line and plumb point mode with automatic levelling (see figure B):
The measuring tool generates one horizontal and one vertical laser line and two
plumb points.
Cross-line mode with incline function (see figure C): The measuring tool gen-
erates one horizontal and one vertical laser line.
Once the measuring tool has been switched on, it is in cross-line operation with auto-
matic levelling.
To change the operating mode, press the button for laser operating mode (3) until the
required laser operating mode is displayed by the corresponding "Laser operating mode"
indicator (5) lighting up.
Automatic Levelling
Working with automatic levelling
Position the measuring tool on a level, firm support or attach it to a tripod (11).
Select one of the operating modes with automatic levelling.
The automatic levelling function automatically compensates irregularities within the self-
levelling range of ±4°. The levelling is finished as soon as the laser lines stop moving.
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-level-
ling to take place.
In case of ground vibrations or position changes during operation, the measuring tool is
automatically levelled again. Upon levelling, check the position of the laser beams with
