# Starting Operation of the rotary laser

- Keep the work area free from obstacles that could reflect or obstruct the laser beam. For example, cover any reflective or shiny surfaces. Do not measure through panes of glass or similar materials. The measurements may be distorted by a reflected or obstructed laser beam.

Horizontal position | Vertical position

Position the measuring tool on a stable surface in the horizontal or vertical position, mount it on the tripod (32) or on the wall mount (36) with the alignment unit.

Due to its high levelling accuracy, the measuring tool is very sensitive to knocks and vibrations and changes in position. Take care, therefore, that the measuring tool is stable to avoid interruptions to the operation caused by relevelling.

To switch on the measuring tool, press the on/off button (4). All indicators light up briefly. The measuring tool emits the variable laser beam (6) and the upwards plumb point (9) from the outlet apertures (8).

- Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).

The measuring tool immediately starts automatic levelling. During levelling, the status indicator (3) flashes green, the laser does not rotate and flashes.

The measuring tool is levelled in as soon as the status indicator (3) lights up green continuously and the laser lights up continuously. After levelling is completed, the measuring tool automatically starts in rotational operation.

- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.

You can already set the operating mode during levelling with the rotational operation button (5) or the line operation button (11). In this case, the measuring tool starts in the set operating mode after levelling is completed.

To switch off the measuring tool, press the on/off button (4) again.

To save the batteries, the measuring tool is automatically switched off when not within the self-levelling range for more than 2 hours or when the shock warning is actuated for more than 2 hours. Reposition the measuring tool and switch on again.
