  • Page 3: Intended Use

    The STABILA LAR 300 rotation laser is an easy-to-use rotation laser for horizontal levelling and establishing plumb lines. The LAR 300 has a sealed enclosure (IP 65) for use on build- ing sites. It is self-levelling within a range of ± 5°.

  • Page 4: Safety Instructions For Laser Units

    Do not look into the direct or reflected beam. The STABILA laser goggles available for our laser units are not safety eyewear: their function is to improve the visibility of the laser beam.

  • Page 7: Commissioning

    6. Commissioning Place the laser unit in the working position. To switch on the laser, press button (3). Holding this button for a longer period will switch the laser off again. Activating the self-levelling function causes the unit to level itself automatically.

  • Page 8: Tilt Function

    7. Tilt function The tilt function warns if any interference to the laser has occurred that may cause misalignment. This ensures that such interference does not go unnoticed. The white LED (5) lights up steadily when the tilt function is active.

  • Page 9: Automatic Operation With Tilt Function

    In “Automatic” operation, the laser unit levels itself automatically. Place the laser unit in the working position. To switch on, press button (3) once. The LAR 300 is in now in “Automatic operation with tilt function”. The automatic levelling process begins. Once levellin is complete, the beam stays on constantly and begins to rotate.

  • Page 10: Automatic Operation With Relevelling

    8.2 Automatic operation with relevelling In some working conditions (where shocks or vibrations affecting the surface occur, for example), the tilt function is disruptive. With automatic relevelling, on the other hand, the unit is readjusted each time it is knocked out of alignment. Press button (3) twice = once to switch on + once to deacti- vate the tilt function.

  • Page 11: Manual Operation With Tilt Function

    9.1 Manual operation with tilt function In manual operation, the laser plane is aligned by hand. Neither self-levelling nor relevelling is active. The unit does not level itself. If the tilt function is active, interference (shocks, vibrations) that could misalign the unit from its exact original setting do not go unnoticed.

  • Page 12: Manual Operation Without Tilt Function

    9.2 Manual operation without tilt function In manual operation without tilt function, automatic mode, the tilt function and relevelling are not active. The laser unit is aligned entirely by hand. The unit does not level itself. Place the laser unit in the working position. Press button (3) twice = once to switch on + once to deactivate tilt function.

  • Page 13: Functions

    10. Functions Rotation function The laser beam rotates through 360° around its axis. Horizontal Plumb-line function Transfers a determined point from the floor to the ceiling. To transfer a plumb line from a floor marking to the ceiling, the laser unit is aligned exactly with the cross mark with the 4 marking points (14).
