Move laser unit close to wall and mark
point P .

Rotate laser unit 180° and mark point P
Measure the vertical distance from
the floor to each point. Calculate the
difference between distances D
to get D and distances D

Calculate the maximum allowed offset
distance and compare to the difference
of D and D as shown in the equation. If

the sum is not less than or equal to the
calculated maximum offset distance the
unit must be returned to your Stanley
Distributor.
