ENGLISH
70
1. Set up the laser in one corner of the floor and turn on the forward
vertical beam.
2. Mark the centre of the beam at three locations (A, B and C) on the
floor along the laser line. Mark B should be at the midpoint of the
laser line.
3. Move the laser to mark B and turn on both vertical beams.
4. Position the beam crossing precisely at mark B, with the forward
beam aligned with mark C.
5. Mark a location (D) along the side vertical beam at least 5 m (18')
away from the unit.
6. Rotate the laser over mark B so that the forward vertical beam
now passes through mark D.
7. Mark the location (E) where the side vertical beam passes by
mark A.
8. Measure the distance between marks A and E. If the measurement
is greater than the values shown in Table 4, the laser must be
serviced at an authorised service centre.
