2. Description

2.1 PR 20 rotating laser
The PR 20 is a rotating laser with one
rotating laser beam.

2.2 Features

_ The tool allows a single person to level
or align in any plane quickly and with
great accuracy (always in conjunction
with the PRA 20 laser detector).
_ The laser's speed of rotation is 300
r.p.m. (revolutions per minute) once the
tool has leveled itself.
_ Automatic leveling (within ±5°
inclination).
_ LEDs for indication of operating status
_ Built-in shock warning: The tool switches
to warning mode (all LEDs blink, laser
stops rotating) when brought out of level
as a result of vibration or an impact dur-
ing operation.
_ Automatic cut-out: The laser remains
switched off and all LEDs blink if the tool
is outside its self-leveling range or if
movement of the mechanism is
physically impeded.
