5.10 Setting the inclination manually
The rotating laser, depending on the application, is mounted or positioned securely.
The PRA 30 laser receiver and the rotating laser are paired.
The PRA 30 laser receiver and the receiving side of the rotating laser are facing each other and in direct
line of sight. The best receiving side of the rotating laser is the side at which the battery is inserted.
1. Position the rotating laser either at the upper edge or lower edge of the inclined plane.
2. Position yourself behind the rotating laser with the control panel facing you.
3. Press the button on the rotating laser and the PRA 30 laser receiver.
◁ The laser switches on, the beam begins to rotate and the "auto leveling" LED lights as soon as the
tool has leveled itself.
4. Press the
button on the rotating laser.
◁ The inclined plane mode LED on the rotating laser then blinks.
◁ The inclined plane mode symbol is shown on the PRA 30 laser receiver.
5. Use the target notch on the head of the tool to align the rotating laser parallel to the inclined plane.
6. To lower the laser plane ahead of the rotating laser, press the
until the desired value is shown in the display.
7. To raise the laser plane ahead of the rotating laser, press the
until the desired value is shown in the display.
◁ If no button is pressed within 3 seconds, the rotating laser levels itself to the previously set value. The
inclined plane mode LED lights.
A long press of the button causes the entered value to change rapidly.
When the angle of inclination is set manually, the rotating laser levels the laser plane once and then
fixes it. Vibration, changes in temperature or other influences that may occur during the course of
the day may affect the position of the laser plane.
5.11 Setting the inclination automatically
The rotating laser, depending on the application, is mounted or positioned securely.
The PRA 30 laser receiver, depending on the application, is mounted on a receiver holder and
telescopic staff.
The PRA 30 laser receiver and the rotating laser are paired.
The PRA 30 laser receiver and the receiving side of the rotating laser are facing each other and in direct
line of sight. The best receiving side of the rotating laser is the side at which the battery is inserted.
1. Position the rotating laser either at the upper edge or lower edge of the inclined plane.
2. Hold the PRA 30 laser receiver right beside the rotating laser and adjust the height the PRA 30 laser
receiver so that the marking notch is at the height of the laser plane. Fix the height of the telescopic staff.
3. Position the telescopic staff with the PRA 30 laser receiver at the other edge of the inclined plane.
4. Press the
button on the rotating laser and the PRA 30 laser receiver.
◁ The laser switches on, the beam begins to rotate and the "auto leveling" LED lights as soon as the
tool has leveled itself.
5. Press the
button on the rotating laser.
◁ The inclined plane mode LED on the rotating laser then blinks.
◁ The inclined plane mode symbol is shown on the PRA 30 laser receiver.
6. Begin automatic alignment by double-clicking the
◁ The rotating laser inclines the laser plane automatically until the mark at the PRA 30 laser receiver is
reached. An signal tone is emitted repeatedly during this procedure.
◁ The rotating laser levels itself once the position has been reached. Successful completion is indicated
by a continuous signal tone with a duration of 5 seconds. The
▽ If automatic alignment cannot be completed successfully, short signal tones are emitted and the
indication in the display disappears.
7. Read the inclination from the PRA 30 laser receiver within 5 seconds.
