D. Alignment of Intermediate and Outer Wing Sections
The outer sections must be aligned with the intermediate wing
sections. Adjustment of the outer wing sections should be
performed by two people as follows:
1. Depressurize the folding cylinder, disconnect both
ends and set aside (leave hydraulics hooked
up).
2. Loosen jam nuts (
A
and
C
)(Fig. 16).
3. Loosen the screws (
B
)(Fig. 16).
4. With one person holding the outer
wing, adjust the stop screws
(
B
)(Fig. 16) until the inner section is
aligned with the outer section and
both stop screws are contacting the
outer section.
5. Tighten jam nuts (
A
)(Fig. 16).
6. Have one person adjust the rigging
screw (
D
)(Fig. 16) until the outer
wing section "snaps" into alignment
and stays when the second person folds the outer section in a few
feet and then back out against stop screws.
7. Tighten jam nut (
D
)(Fig. 16) and check the alignment. If needed,
repeat the adjustment above.
8. Reconnect both ends of the folding cylinder.
Note: For tri-fold booms, repeat the above procedure for the outer
fold section as well as the inner fold section.
E. Wing Tilt Adjustment
The horizontal alignment of the
wings is done by adjusting the
retracted tilt cylinder (Fig. 17).
The boom tip must point slightly
upward. If necessary, adjust the
wing as follows:
1. Tilt wing approximately 15°
up.
2. Loosen jam nut (
A
)(Fig. 17).
