an adjustment is necessary. Contact your authorised dealer

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 ± 2.5 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 ± 2.5 mm.
Repeat the process by turning the laser to the left.
!
Regularly check the calibration before use, after transport
and after extended periods of storage.
