Adjustment of the wire should beundertaken with the boom unfoldedand the hydraulic rams F discon-nected from the boom wings.Tighten nut G so that the tip israised 12 cm for the 12 m boomand 15 cm for the 15 m boomfrom the horizontal line of thecentre section.5. Parallel adjustment of inner section1. Cautiously activate the hydraulic ramsF so they are fully extended. Makesure the extension H is screwedin and tight.2. Loosen counter nut Iand adjust the ram eye Jso that when connected,the boom wings areparallel with the centresection. The ram mustforce the boom tip downso distance “X” is equal.6. Adjustment for transport bracketsand air stream angleFold boom and lower cautiously intotransport brackets. Loosen coun-ter nut K and adjust L so theboom rests in the middle ofthe brackets.When the boom is lowered,it must be firmly hooked ontothe transport bracket M.Loosen counter nuts andadjust bolt N so that theboom hooks firmly into placewithout exerting excessiveforce on the boom wings.Unfold the boom.
