7.5 Working in the horizontal plane
7.5.1 Setting up
1. Set up the tool in a suitable position for the application, e.g. on a tripod. Alternatively, the rotating laser may be
mounted on a wall bracket. The angle of inclination of the surface on which it stands should not exceed ± 5°.
2. Press the on/off button.
The auto-leveling LED blinks green.
The laser switches on, the beam begins to rotate and the "auto leveling" LED lights as soon as the tool has
en
leveled itself.
7.5.2 Alignment using the PRA 90 automatic tripod
NOTE
This function is available only with the PRA 90 automatic tripod.
When used for the first time, the PRA 30 laser receiver must be paired with the tripod (see 6.9.2).
With the optional PRA 90 automatic tripod you can set the height of the laser plane to the desired level manually or
automatically.
1. Mount the tool on the PRA 90 automatic tripod.
2. Switch on the rotating laser, the automatic tripod and the laser receiver. Set the height of the laser plane manually
(see 7.5.3) or automatically (see 7.5.4).
7.5.3 Manual alignment 6 10
Press the +/- buttons on the laser receiver or the arrow buttons on the PRA 90 to shift the horizontal plane up or down
(parallel).
7.5.4 Automatic alignment 6 11
1. Hold the laser receiver at the desired height with the detection area facing the PRA 90 control panel. Hold the
laser receiver still while alignment is taking place and take care to ensure that the line of sight between the laser
receiver and the tool is not obstructed.
2. Press the "Automatic alignment" button on the laser receiver twice in quick succession (double-click). Double-click
the button again to complete the procedure.
This double-click starts the process of bringing the laser plane into alignment, i.e. the tripod elevates or lowers
itself to the required height. A constant signal tone is emitted while this is taking place. As soon as the laser beam
strikes the detection area of the laser receiver, the beam moves to the position of the marking notch (reference
plane).
After the position has been reached and the rotating laser has leveled itself, a signal tone with a duration of 5
seconds indicates that the process is complete. The "Automatic alignment" symbol is then also no longer shown.
3. Check the height settings in the display.
4. Remove the laser receiver.
NOTE If the automatic alignment process was not successful, short signal tones are emitted and the "Automatic
alignment" symbol goes out.
