Both sensor and reflector should be at the same height, as low as possible, yet just high
enough for the beam to clear the coupling flange. They should also visually appear to be rota-
tionally aligned to each other.
In some cases, if the coupling is large enough, a coupling bolt can be removed and the laser
beam shot through the bolt hole.
Make the final adjustments, loosening the brackets slightly if necessary, then rotating them
and re-tightening.
