Operating instructions The STABILA LAR-200 rotation laser is an easy to operate rotation laser for horizontal levelling and plumb lines in a sealed housing ( IP65). It is self-levelling in a range of ± 5°. The laser beam can be received at distances of up to 150 m with the use of a receiver, even when it is no longer visible to the naked eye.
In Class II laser equipment, your eyes are protected from accidental, short- term exposure to the laser beam by the lid-closing reflex and/or the reflex reaction to turn one's head. This equipment can therefore be used without additional protective measu- EN 60825-1 : 03 10 res.
Checking the calibration The LAR-200 rotation laser has been designed for building site use and leaves our factory perfectly calibrated. As with any precision instrument, however, its calibra- tion must be regularly checked. The unit should be checked before starting any new tasks, particularly when the unit has been exposed to strong vibrations.

Horizontal checking Set up the rotation laser on a smooth, level surface or on a tripod 25 ft or 50 ft / 5m or 10m from a wall with the front facing the wall. Switch the unit on (button 3) and wait for it to level automatically. Mark the position of the visible laser dot on the wall - Measurement 1 (Point 1).
