INSTALLATION INSTRUCTIONS
For best result use Teflon ® tape on all fittings.
1. The three boom assemblies are not on the packing list but are in the carton. The long boom assemblies are the right and left
booms. The labels are located on the pivot brackets (Ref 13 and 26). The small boom assembly is the center boom. Each
assembly is shipped with the nozzle bodies (16-996) attached. The remainder part of the nozzles need to be installed. You can
NOT order these boom assemblies as one unit. Please refer to parts drawing for individual parts.
2. Mount small boom assembly to the boom carriers on sprayer using four boom brackets (Ref 8), four bolts, 3 / 8 - 16 x 5 1 / 2 and
four lock nuts, 3 / 8 - 16 (Ref 7). One boom bracket should go on boom assembly and one on boom carrier. 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 20 and 22) on the center mount (Ref 21) using 3 /
8
- 16 x 1 1 /
4
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.
4. Take right boom and slide pivot bracket (Ref 24) in center mount (Ref 21) and hold in place with 1 / 2 - 13 x 5 1 / 2 bolt and 1 / 2 - 13
center lock nut (Ref 32). Do not over tighten, boom must be able to move up and down. Repeat for left boom.
5. Install boom lifts (Ref 31) using clevis pin and cotter pin (Ref 27) so the bushing end hooks to the pivot bracket (Ref 24) and the
slotted end hooks to the actuator bracket (Ref 20 and 22).
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. Use the adjustment slots on the boom lifts to completely lift and lower booms.
8. 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.
9. To install boom carriers (15-328) and latch (15-437) see drawing. The boom holders should point upward and latch pointing
outward. Use 8 - 32 x 1
1 /
2
machine screws, nuts and washers to install latch to boom carriers.
10. To put booms into boom carriers, booms must be down. Push booms towards front of machine and lift boom slightly to clear
fenders. Disconnect latch and put it over brush guard and reconnect.
11. Put the viton gaskets (16-800), Raindrop tips (16-805) and quick TeeJet caps (16-921) on the nozzle bodies (16-996) on the
three boom sections.
12. Make certain set screws (B) on both sides are completely screwed in and locked with the lock nut.
