ASSEMBLY INSTRUCTIONS

1.Begin by referring to the boom carrier (#1) mounting to the sprayer frame (page 1) or mounting to the height adjust (pages 2 & 3). After the boom carrier is mounted begin assembling the center section.

2.Mount the left floater tube (#2) to the boom carrier (#1) using one 1/2"

x5" bolt (#11), pivot bushing (#5), and one 1/2" locknut (#10). Next mount the right floater tube (#3) to the boom carrier (#1) using one 1/ 2" x 5" bolt (#11), one pivot bushing (#5), and one 1/2" locknut (#10).

3.Place the auto-level springs (#4) between the left and right floater (#2 & 3) and the boom carrier (#1). Attach the left floater (#2) and right floater (#3) using two linkage plates (#6), two pivot bushings (#5), two 1/2" x 4-1/2" bolts (#9), and two 1/2" locknuts (#10).

4.Now mount the shock (#8) to the right floater (#3) using one 1/2" x 5" bolt (#11) and one 1/2" locknut (#10). Mount the opposite end of the shock to the boom carrier (#1) using one 1/2" x 3" bolt (#12) and one 1/2" locknut (#10).

5.Mount the auto-level linkage (#7) to the left floater (#2) using one 1/2"

x4-1/2" bolt (#9), one pivot bushing (#5), and one 1/2" locknut (#10). NOTE: Make sure the arrows on the linkage are up as shown above. Mount the auto-level linkage (#7) to the right floater (#3) using one 1/ 2" x 4-1/2" bolt (#9), one pivot bushing (#5), and one 1/2" locknut (#10).

6.Mount the center section onto the boom center section (#22). Secure the linkages (#7) on the right and left to the bottom of the boom center section (#22) using two 1/2" x 4-1/2" bolts (#9), two pivot bushings (#5) and two 1/2" locknuts (#10).

7.Attach the left and right auto-level sway control brackets (#13 & 14) to the boom carrier (#1) using six 3/8" x 1-1/4" bolts (#19), six 3/8" flatwashers (#20) and six 3/8" locknuts (#21). Next mount the UHMW

wear pads (#15) to the sway control brackets (#13 & 14) using four 1/ 4" x 1" slotted flat head screws (#16) and four 1/4" locknuts (#17). Assemble the UHMW wear pads (#15) to the auto-level sway control guides (#23) and the bottom center support bracket (#34) using eight 1/4" x 3/4" slotted flat head screws (#18). Mount the sway control guides (#23) with UHMW wear pads to the right and left sway control brackets (#13 & 14) using two 3/8" x 1-1/4" bolts (#19), two 3/8" flatwashers (#20) and two 3/8" locknuts (#21). Bolt the top of the sway control guides and sway control brackets together using two 1/2" x 4- 1/2" bolts (#9), two springs (#24) and two 1/2" locknuts (#10). Mount the bottom center support bracket (#34), with UHMW, to bottom tube of boom carrier (#1) using four 3/8" x 2-1/2" square u-bolts (#30), eight 3/8" flatwashers (#20) and eight 3/8" nylon insert locknuts (#21).

8.Assemble the center boom nozzle mounting plates (#29) to the center section (#22) as shown using three 3/8" x 2-1/2" sq. U-bolts (#30) and six 3/8" locknuts (#21). Next mount the center nozzle tube (#32) to the mounting plates (#29) using three 5/16" x 1-1/2" sq. U-bolts (#31) and six 5/16" locknuts (#33).
