1.Shut off current; disconnect leads and remove air switch.
2.Lay air switch assembly on flat surface. Adjust air blade at “A” (figure 1) so that air blade lays flat and surface “B” is parallel to the flat surface.
3.Place 3/8” x 5/8” spacer bar or equivalent “C” (figure 2) under air blade in position shown; hold switch mounting bracket firmly and adjust switch actuator “D” with needle nose pliers at “E” by twisting actuator right or left, whichever is needed, so that switch closes when end of air blade engages bar “C”.
