Operating instructions The STABILA LAPR-150 rotation laser is an easy to operate rotation laser for horizon- tal and vertical levelling and plumb lines. It is self-levelling in a range of ± 1°. The laser beam can be received at distances of up to 90 m (570 ft) with the use of a receiver, even when it is no longer visible to the naked eye.
Main applications: Leveling Set the unit on a firm base or tripod so that the bubble in the enclosed vial (9) does not touch the sides of the vial. This vial is used only for rough adjustment. Tip: It is useful to set up the rotation laser safely at the same distance to the subsequent measurement points.

Marking out vertical areas (vertical leveling) Tilt the motor head 90° in its end position and engage the deflection optics in the end position. Align the unit so that the vertical plane described by the optics is parallel or at right angles to a line of reference. Switch the laser on via the sliding switch 3).
Checking the calibration The LAPR-150 rotation laser has been designed for building site use and leaves our factory perfectly calibrated. As with any precision instrument, however, its calibration must be regularly checked. The unit should be checked before starting any new tasks, particularly when the unit has been exposed to strong vibrations.

Vertical check (motor head tilted 90°) Two parallel wall surfaces at least 5m ( 17 ft ) apart are required for the vertical check. Set up the rotation laser on a tripod directly in front of wall A. Tilt the motor head 90° in the direction of wall A. The deflection optics should be set in the end position.
