I I I I INSTALLATION INSTRUCTIONS
For best results use Teflon ® tape on all fittings.
1. The three boom assemblies are not on the packing list but are in carton. The long boom assemblies are the
right and left booms. The labels are located on right and left pivot brackets (Ref 17 and 34). The small boom
assembly is the center boom. You can NOT order these boom assemblies as one unit. Please refer to parts
drawing for individual parts.
2. Mount small boom assembly to rear upright support on sprayer using four boom brackets (Ref 6), four bolts, 3 /

and four lock nuts, 3 /

- 16 (Ref 7). One boom bracket should go on boom assembly and one on upright
support of sprayer. Do the same for right and left side. Place boom at desired level (approximately 20" (51 cm)
nozzle height) and center. Tighten bolts.
3. Put the actuator brackets (Ref 5 and 10) on the center mount (Ref 8) using 3 /

bolts, washers and lock
nuts, with washers over the slots. Snug up the bolts so that you can adjust actuator brackets with the set screws
(Ref A) on the center mount after booms have been mounted.

bolt and 1 /

clevis pins and 1 /

x 1 cotter pins. It may be necessary to lift boom slightly for proper fit. Repeat process for other boom.
6. Hook hoses to respective fittings using hose clamps (18-040). The hose coming from right side of sprayer goes
to straight fitting on right boom. Center hose from sprayer goes to straight fitting on center boom. The left hose
from sprayer goes to straight fitting on left boom. Be sure all clamps are tight.
7. Connect wire harness to actuator. Use two nylon ties (22-075) to hold wire to fixed end of actuators.
8. Use boom switches to completely extend actuator and lower booms.
9. Using set screws (Ref A) adjust actuator brackets so nozzles of booms are at same height with nozzles of center
section. Tighten bolts holding actuator brackets to center mount and locknuts on set screws.
10. Make certain set screws (B) on both sides are completely screwed in. Raise booms with boom switches all the
way up, adjust set screws (A) so they contact the stop.
