CHECKING 90º ACCURACY BETWEEN VERTICAL BEAMS (FIG. 9)
Checking 90º accuracy requires an open floor area at least 10 m x 5 m (33' x 18').
Refer to Figure 9 for the position of the DW089-XE at each step and for the location of
the marks made at each step. Always mark the center of the beams’ thickness.
1. Set up the laser in one corner of the floor and turn on the forward vertical beam.
2. Mark the center 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 below, the laser must be serviced at an authorized service
center.
