Wing Folding
Refer to Figure 12
Normal boom use may cause wing misalignment.
If the inner- and outer-arm sections are out of
alignment, the outer arm (A) will miss the fold
bracket (B) on the inner arm when boom is folded.
To realign wing sections, loosen 1/2-inch bolts at
arm joint. Swing outer-arm section until it is
aligned with inner-arm section. Retighten bolts.
Normal boom use may also shift the folding brack-
ets along the inner-arm section. When properly
adjusted, the outer arm will meet the fold bracket
at the stop (C). Loosen u-bolts and reposition
brackets as necessary.
