• If laser radiation strikes your eye,
you must deliberately close your
eyes and immediately turn your
head away from the beam
• Do not make any modifications to
the laser equipment
• Have the measuring tool repaired
only through qualified specialists
using original spare parts (this
ensures that the safety of the
measuring tool is maintained)
• Do not allow children to use
the laser measuring tool
without supervision (they could
