7 Operation

NOTE
The functions "Speed of rotation" and "Line function" can
also be controlled directly from the PRI 2 rotating laser.
7.1 Working with the PRA 2 remote control unit 3
The PRA 2 remote control unit makes working with the
rotating laser more convenient and is required in order to
make use of certain functions.
7.1.1 Selecting the speed of rotation (revolutions
per minute)
After switching on, the PRI 2 rotating laser always begins
to operate at a speed of 150 revolutions per minute.
Working at a slower speed of rotation can, however,
make the laser beam appear much brighter. The speed
of rotation can be altered by pressing the speed of
rotation control button the required number of times: 0 >
90 > 150 > 300 >600 >0.
7.1.2 Line function
The area of the laser beam can be reduced to a line
by pressing the line function button. The laser beam
then appears considerably brighter. The length of the line
can be adjusted by pressing the line function button the
desired number of times: 0° > 5° > 10° > 15° > 0°. The
length of the line depends on the distance between the
laser and the wall or the working surface. The laser line
can be shifted to the left or the right, as desired, by
pressing the direction buttons (right/left).
7.2 Working with the PRA 22 laser receiver
(accessory)
The laser receiver can be used at distances of up to 150
m or when working in unfavorable light. The laser beam
is indicated visually and by an audible signal.
NOTE
For further information, please refer to the PRA 22 oper-
ating instructions.

2. Insert the batteries in the battery compartment. Take
care to observe correct polarity.
3. Close the battery compartment cover.
7.3 Working in the horizontal plane
In order to work in the horizontal plane, the rotating laser
must be set up with the rotation head facing upwards.
Set up the tool in a suitable position for the application,
e.g. on a tripod.
Press the on/off button.
Shortly before leveling is complete, the laser beam
switches on and begins to rotate (at a speed of 150
revolutions per minute).
7.4 Working in the vertical plane 5
To work in the vertical plane, set up the tool so that the
rotation head faces to the side. This can be achieved by
standing the tool on the pins, so that the control panel
faces upwards. Slide the reference indicator upwards.
The tool can then be aligned with the aid of the laser
reference point. Alternatively, the rotating laser can be
mounted on a tripod with the PRA 70/71 wall bracket.
Press the on/off button. When leveling is complete, the
laser beam switches on and begins to rotate (at a speed
of 150 revolutions per minute).
7.5 Vertical alignment of the laser beam
The laser beam can be aligned vertically by pressing the
+/- buttons on the remote control unit. Manual alignment
of the rotating laser must be carried out exactly.
1. Position the rotating laser on the desired reference
point and switch it on.
2. Use the rotation or line function buttons to set
the desired function (for example, projection of a
medium-sized line).
3. You can then align this line manually. The servo
buttons can be used to move the line to the left or
to the right (maximum +/-5°).
7.6 Working with slopes 6
1. Mount the tool in a suitable position for the applica-
tion to be carried out (e.g. on a tripod).
The shock warning is deactivated.
The tool cannot begin operation; Cause:
The tool has been moved - it cannot
level itself.
Battery power should last a further ap-
prox. 2 hours
