Checking the vertical line: Position the device about 5 m from a wall. Fix a
plumb bob with a line of 2.5 m length on the wall, making sure that the bob
can swing freely. Switch on the device and align the vertical laser to the plumb
line. The precision is within the specified tolerance if the deviation between the
laser line and the plumb line is not greater than ± 0.5 mm.
Checking the horizontal line:
Position the device about 5 m from a wall and
switch on the cross laser. Mark point B on the
wall. Turn the laser cross approx. 2.5 m to the
right and mark point C. Check whether the
horizontal line from point C is level with point B to within ± 0.5 mm.
Repeat the process by turning the laser to the left.
!
Regularly check the adjustment before use, after transport and after
extended periods of storage.
Hand receiver mode
Optional: Working with the laser receiver RX
Use an RX laser receiver (optional) to carry out levelling at great distances
or when the laser lines are no longer visible.
To work with a laser receiver, switch the line laser into hand receiver mode
with the Hand receiver mode button (11). The laser lines will now pulsate
with high frequency, making the laser lines darker. The laser receiver RX
can detect these pulsating laser lines.
Hand receiver mode can be used for horizontal or vertical levelling as well
as for slope functions.
!
Follow the operating instructions of the corresponding laser receiver.
