To establish square, place the PLS
5
with the #2 down beam over the layout reference line. See Fig.
7. Place the pendulum target on that line, and center #1 forward beam on the center of the target.
Once centered, move the pendulum target to square on #4 left beam or #5 right beam. Make a
mark on the floor or surface near the laser and the second mark at the desired distance from the
laser. See Fig. 7.
