e) If the horizontal alignment is very poor the laser lines might travel
outside the detector areas. If this happens a rough alignment
must be done. Do this by aiming the laser lines at the positioning
detectors in the 9 o'clock position. Turn the measuring units to the
3 o'clock position when the lines will hit outside the detector
areas. Adjust the lines to the position half-way between the
detector centre and the actual position by means of the
adjustment mechanism as per fig. 15. Align the Movable machine
until the lines hit the centre of the positioning detector.
