Alignment of center and inner wing sections

1. Unfold the boom and check alignment of the inner section with
the center section.
2. If adjustment is necessary, relieve pressure from the cylinder by
folding the boom a few inches.
3. Disconnect cylinder rod eye (A) from the inner section. Note that
some cylinder rods have a machined flat which can be used for
adjustments. If using this one for adjustment, leave the rod eye
pinned to the boom.
4. Loosen jam nut (B) and adjust the length of the rod eye (A). IN = to
move the boom forward OUT = to move the boom rearward
5. Tighten the jam nut (B) again. (Reattach the cylinder rod to the
boom again, if it has been loosened).
6. Pressurize the cylinder to check boom alignment.

Alignment of inner and outer wing sections

1. Unfold the boom and check that the boom wing is aligned. If
adjustment is needed:
2. Remove rubber stop (A) from the inner section.
3. Adjust the position of the adjusting bolt (B) on the inner section so
that the cap of the bolt head (B) contacts top stop plate on outer
section with inner and outer sections aligned. Tighten it in this
position.
4. Replace stop device (A).
Please note that the rubber stop (A) should be compressed 1/8" - 3/16"
(3-5 mm). Therefore, check that the distance between the tabs (C) is a
little less than the length of the rubber stop itself. The rubber stop may
need to be spaced out with 1 or more flat washers in order to obtain
correct compression. Tighten nut to hold it in place.
