1. 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 building sites. It is self-levelling within a range of ± 5°.
The laser beam can be picked up using a receiver even where
it can no longer be discerned with the naked eye.
If you still have questions aer reading through the operating
instructions, you can obtain advice by telephone:

2. Safety instructions for laser units
LASER
2
In Class 2 laser units, your eyes are usually protected from accidental, short-term exposure to the laser beam by the eyelid-closing reflex and/or the reflex reaction to turn
one’s head. If a laser beam hits your eye, deliberately close your eyes and move your
head out of the path of the beam. 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.
