Tighten. See figure 10. 17. Assemble a spring and a 3/8" plain hex nut onto a 3/8" x 1-1/4" hex bolt. Fasten the bolt to the hole shown in the top of the welded bracket using a 3/8" nylock nut. Tighten so that the nylock nut is even with the end of the bolt. See figure 10. 18. Repeat steps 16 and 17 for the (LH) boom arm assembly. 13. Tighten securely the 12 bolts and nuts fastening the frame strap and the front and rear angles to the side angles. (Figures 1 and 2) Tighten only until snug the 2 bolts and nuts fastening the axle to the frame. (Figure 4) Tighten securely the 4 nuts fastening the tongue to the frame. (Figure 3) FIGURE 10 (RH) SIDE VIEWED FROM REAR 6 19. Attach the (RH) boom arm assembly to the (RH) boom mount assembly as shown in figure 11, using a 3/8" x 4-1/4" hex bolt, three 3/8" flat washers, and one 3/8" nylock nut. Do not overtighten. 20. Place a 3/8" x 2-1/2" hex bolt through the loose end of the spring and then assemble a 3/8" plain hex nut onto the bolt. Fasten the hex bolt to the boom mount assembly using a 3/8" nylock nut. Tighten the nuts, exposing one or two threads on the end of the bolt. See figure 11. 21. Repeat steps 19 and 20 for the (LH) boom arm assembly. 3/8" x 2-1/2" (RH) BOOM HEX BOLT ARM ASSEMBLY (RH) BOOM MOUNT ASSEMBLY FIGURE 11 (RH) SIDE VIEWED FROM REAR 24. Tie the hoses to the front of the boom using four nylon ties per side as shown in the front view in figure 13. After tightening, cut excess length off ends of ties . 25. Insert a 3/32" hair cotter pin into the welded pin at each end of the boom. These pins will be used to lock the boom arm to the transport bracket when the arm is in the folded position. See figure 13. NOTE: To help prevent leaking, use thread tape when assembling the "Y" valve fitting and the pressure gauge in the following paragraphs. 22. Attach the hose assembly to the front of the boom, with the nozzles pointing to the rear. Remove the nozzle nut, nozzle, strainer screen and elbow nut, from the elbow fittings and place the elbow through the hole at the end of the boom arm. Secure it using the plastic elbow nut. Insert the strainer screen and then assemble the spray nozzle and the nozzle nut, keeping the nozzle opening facing down while tightening. See figure 12. 23. Attach the hose assembly tee fittings to the boom using the same procedure as was used for the elbows. See figure 12. 26. Carefully screw the "Y" valve fitting onto the fitting attached to the tee support bracket. The valve levers should face up. See figure 14. 27. Carefully screw the pressure gauge into the top of the tee fitting as shown in figure 14. 28. Place the 1/4" hose clamp over the end of the spray gun hose. Push the hose onto the hose barb on the front of the tee fitting. Secure the hose to the barb with the hose clamp. See figure 14. FIGURE 12 (RH) SIDE VIEWED FROM REAR FIGURE 14 7 29. Connect the boom connecting hose and the return (bypass) hose to the "Y" valve fitting, placing a hose gasket in the swivel nut on each hose. Insert the return hose into the top of tank. See figure 15. IMPORTANT: Connect sprayer to 12 volt batteries only! 30. Hook up the wiring to the vehicle battery. Connect the red wire on the fused wire harness to the positive post on the battery or the "HOT" connection on a vehicle switch or the ammeter. The brown wire may be grounded or connected to the negative battery post. See figures 16 and 17. IMPORTANT: Keep wiring away from hot engine parts, rotating parts and pinch points.

If a leak should occur, thread tape may be used to better seal the fitting. PUMP PRESSURE SWITCH The pump is equipped with a pressure switch. The pressure switch senses outlet pressure of the pump and will turn off the electrical power to the pump at a predetermined high pressure point (45 PSI). If the flow demand is very low, the pump may reach this high pressure point and the switch will cause "cycling" (the pump cycles on and off rapidly). This is not a problem unless the pump continuously cycles within one second intervals for long periods of time. ADJUSTING OPERATING PRESSURE The sprayer is equipped with a "Y" fitting containing two valves. The bypass valve controls the flow to the return (bypass) hose. The amount of flow through the return hose determines the operating pressure of the boom or the spray gun. Adjust the bypass valve while either the boom or the spray gun is in use to obtain the desired pressure, indicated by the pressure gauge. The tip chart on page 11 shows how different pressure settings affect boom ...
