Adjusting Front Fold Cable

CAUTION: Rear cable can snap and injure you or someone else if tensioned when the boom is unfolded. Always adjust front cable first with the boom unfolded and rear cable last with the boom folded into transport position.

1. Unfold boom into operating (spraying) position.

2. Slide a straight edge (A) down the underside of intermediate boom section until it just contacts the front cable (B).

3. Suspend a 4.5 kg (10 lb) weight (C) from the straight edge-to-cable contact point and check deflection by measuring the distance from the straight edge to the cable. Cable should deflect 13-20 mm (.50-.75 in.) (D).

4. Loosen jam nuts (A) and adjust turnbuckle (B) for proper cable deflection.

5. Tighten jam nuts and remove weight.

IMPORTANT: Check boom alignment again. If front cable was tightened, the wing assembly will move forward; or if loosened, wing will move rearward. Adjust fold cylinder (if necessary) as described in Aligning Wing Assemblies in this section.
