Rotate laser unit to other corner or
reference point.
3.
Measure the vertical distances between
P
1
and the horizontal beam from the 2nd
location.
4.
Calculate the maximum allowed offset
distance and compare to D
2
. If D
2
is
not less than or equal to the calculated
maximum offset distance the unit must be
returned to your Stanley Distributor.
