Boom Wing Fold Out Adjustment
If the secondary boom wings do not unfold properly, with the boom in the folded position, adjust the
turnbuckle at the rear of the primary boom wing until the cable is tight. Recheck the boom
breakaway tension and adjust if necessary.
Boom Breakaways
The tension of the boom breakaways should be checked and adjusted as needed. If the tension on
the breakaways is too great, the boom may be damaged if it strikes a stationary object. Adjust the
tension as needed by turning the turnbuckles located on the front side of the boom wings (when
boom is completely unfolded). Adjust as required. Tighten the locknuts against the turnbuckle when
complete.
