3. Press the on/off button .
After the tool has leveled itself automatically, it projects a stationary laser beam vertically downwards. This
projected point is a reference point (not a plumb point) and can be used to help position the tool.
4. Align the tool so that the projected laser point coincides exactly with a reference point (e.g. nail on a batter board).
5. Now line up the laser plane with the second reference point manually (see 6.7.1) or automatically (see 6.7.2).
The laser begins to rotate automatically as soon as you begin the alignment operation.
6.7.1 Manual alignment

1. Press the arrow keys
on the laser receiver in order to align the vertical plane manually.
6.7.2 Automatic alignment and surveillance
6 14
1. Mount or hold the laser receiver with the marking notch at the desired alignment point and facing the rotating
laser.
2. Double-click the “Automatic alignment” key . Double-click the key again to complete the procedure.
The laser plane alignment procedure then begins. A constant signal tone is emitted while this is taking place.
The direction of the search can be changed by pressing the “Automatic alignment” key once.
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).
Once the position is reached (i.e. the marking notch is found), a signal tone with a duration of 5 seconds indicates
that the process is complete.
The laser receiver switches automatically to surveillance mode and checks at regular intervals whether the laser
plane has shifted. If it is found to have shifted, the laser plane will be readjusted to the original marking notch as
far as possible. If the marking plane is outside the leveling range of ±5°, direct line of sight between the rotating
laser and the laser receiver is obstructed for a long period or the alignment process is not completed successfully
within a time of 2 minutes, then short signal tones are emitted, the laser stops rotating and the “Automatic
alignment” symbol disappears. This indicates cancellation of the automatic alignment process.
3. After the automatic alignment process is completed and, instead of leaving the receiver in position, you wish to
use the device again as a receiver, you can leave surveillance mode again by pressing the “Automatic alignment”
key twice in quick succession (double click).
6.8 Working with slopes
NOTE
If the tool measures a change in temperature of more than 10 degrees, laser rotation stops for about 40 seconds.
During this time the tool corrects all errors that may have been caused by the temperature change. After this automatic
correction the tool resets the laser plane to the previous inclination and the laser again begins to rotate.
Tool is level
Leveling switched off in order to work with the slope adapter
