Switching On/Off
To switch on the measuring tool, slide the on/off switch (4) to the "ON" position. As
soon as it is switched on, the measuring tool emits laser lines from the outlet
apertures (5).
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 (4) to the OFF position. The
pendulum 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 several operating modes, which you can switch between at any
time:
– Cross-line operation (see figure A): The measuring tool generates a horizontal laser
plane (360° circumferential laser line) and a vertical laser line pointing forwards
– Horizontal mode (see figure B): Generates a horizontal laser plane (360° circumferen-
tial laser line)
– Vertical mode (see figure C): Generates 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 laser mode button Mode (1).
All operating modes can be used with both automatic levelling and the incline function.
Automatic Levelling
Working with automatic levelling (see figure E)
To work with automatic levelling, the automatic levelling status indicator (3) must not
light up continuously. If necessary, switch automatic levelling on again by pressing the in-
cline function button (2) so that the status indicator goes out.
Position the measuring tool on a level, firm surface or attach it to the tripod (11), or the
telescopic shaft (13).
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 beams begin to
flash.
