1. Remove all items from carton and lay out as shown on pages 2 and 3.

4. Assemble a hitch arm to the inside of a frame tube underneath the tank. Use two 5/16" x 2" hex bolts and 5/16" hex nuts as shown in figure 2. Do not tighten yet. Repeat for other side.

2. Assemble the axle through the large holes in the frame tubes. If the axle will not fit, slightly loosen the bolts in the frame tubes to align the holes. Retighten the bolts after assembling axle. See figure 1.

3. Assemble a 1/2" flat washer, a spacer, a second 1/2" flat washer, a wheel (valve stem facing out) and a third 1/2" flat washer onto the axle. Lightly tap a hub cap onto the end of the axle. Repeat on other end of axle. See figure 1.

Outside the tank, assemble the nylon washer, then the nylon nut onto the drain body. Tighten the nut securely enough to prevent leaking, being careful not to damage the plastic parts. Place the O-ring inside the nylon cap and screw the cap onto the end of the drain body. See figure 4.

13. Insert a garden hose gasket into the swivel nut on the boom connecting hose. Screw the nut onto the lower outlet of the "Y" valve fitting. See figure 8.

14. Slide the 1/4" hose clamp onto the spray gun hose. Push the hose onto the hose adapter on the side of the "T" fitting as shown in figure 8. Tighten the clamp around the hose and the adapter. Wrap the hose around the tank and snap the spray gun into the clips on the side of the tank.

15. Carefully screw the pressure gauge into the top of the "T" fitting. See figure 8.

16. Attach the sprayer to the tractor hitch and connect the wiring to the tractor battery. The red wire must be connected to the positive post on the battery or to the "HOT" connection on a tractor switch or ammeter. The brown wire may be grounded or connected to the negative battery post. See figures 9 and 10.

IMPORTANT: This sprayer should be connected to 12

volt batteries only!

BEFORE STARTING It is important to test the boom and spray gun with

plain water before using chemicals. This will enable you to check the sprayer for leaks and to set the spray pattern and nozzle pressure. 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 (60 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 is subject to continuous cycling within one second intervals for long periods of time.

ADJUSTING OPERATING PRESSURE

The sprayer is equipped with a "Y" fitting containing a bypass valve and a boom valve. The bypass valve controls the flow to the return (bypass) hose. The amount of flow through the return hose determines the operating pressure when the boom or the spray gun is in use. 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 9 shows how different pressure settings affect boom application rates.

ON-OFF ADJUSTMENT OF BOOM NOZZLES

The boom valve on the "Y" fitting controls flow to the boom nozzles. It should be either completely open or completely closed. The boom operating pressure can be controlled using the bypass valve on the "Y" fitting.

ADJUSTING SPRAY GUN NOZZLE

Turn the nozzle on the spray gun to adjust the spray from a cone shaped fine mist to a straight stream. Control the spray gun operating pressure with the bypass valve on the "Y" fitting. Maximum spray gun pressure can be attained when the boom is shut off.

SETTING THE BOOM FOR SPRAYING

The correct positioning of the boom places the nozzles approximately 40" apart and 14" above the ground. This gives a spray width of approximately 80" with a slight center overlap. See figure 11.

a. Slide the boom bars out to the ends of the

slots.

b. Swivel the boom bars until the nozzles are

approximately 14" above the ground.

c. Make sure the nozzles are adjusted so that the

openings point straight down.

USING THE SPRAYER

1. Determine the application rate (gallons per 1,000 sq. feet or gallons per acre) based on the chemical manufacturers recommendations. Use this rate to help select the pressure setting and tractor speed in the following instructions.

2. Determine the approximate square footage of the area to be sprayed and estimate the number of gallons required. This can help avoid unneeded solution left in the tank.

3. Determine the appropriate speed at which to travel, based on the chosen pressure setting and the recommended application rate. Use the tip chart on page 9.

4. To determine the throttle setting for attaining the appropriate speed, mark off 100, 200 and 300 feet intervals. The speed chart at the bottom of page 9 indicates the number of seconds it takes to travel these distances. Set the throttle and, with a running start, travel the distances in the number of seconds indicated by the speed chart. Once you have determined the throttle and gear settings needed, mark the throttle location so that you can easily resume the same speed after stopping.

6. Set the operating pressure. Spray with plain water to help determine the best setting. For best results stay in the 20 to 30 PSI range. (At 10 PSI the spray pattern begins to break up, at 40 PSI some drift develops.) Refer to the tip chart on page 9.

7. Add the chemical solution to the tank, following the product instructions.

8. Drive to the starting place for spraying. Set the boom in position for spraying. Set the throttle at the position determined in step 4. Reach back and flip the pump/motor switch "ON" to start spraying.

9. Stay clear of flowers, shrubs and evergreen trees when spraying weed control solutions to prevent contact of the solution with these sensitive plants.

CAUTION: WEAR EYE PROTECTION, GLOVES AND PROTECTIVE CLOTHING WHEN HANDLING AND WORKING WITH LAWN CHEMICALS.

MAINTENANCE

1. Do not store sprayer with any solution left in tank.

2. Periodically clean the strainer in the end of the intake hose at the bottom of the tank. Remove the nylon swivel nut from the hose, pull out the screen and flush it with clear water.

3. Periodically clean the strainers in the boom nozzles. Remove the nozzle, pull out the screen and flush it with clear water.

AFTER EACH USE

4. After use, fill the sprayer part way with water, start the sprayer and allow clear water to be pumped through the plumbing system and out through the boom assembly and the handgun. Use the handgun to thoroughly wash all internal parts of the tank, the outside of the tank and the boom.

5. Refill the tank about half full with plain water and a chemical neutralizer and repeat the cleaning instructions above. Flush the entire sprayer with the neutralizing agent. Follow the chemical manufacturers instructions for disposal of all wash or rinsing water.

ATTENTION!

Do not allow chemicals to sit in pump for

extended times of idleness. Some chemicals will damage the pump valve if allowed to soak untreated for a length of time. Always flush the pump with water after each use. Follow the procedures in the AFTER EACH USE instructions for flushing and disposal.

WINTER STORAGE

6. Drain all water out of the sprayer, paying special attention to the pump and handgun. These items are especially prone to damage from chemicals and freezing weather.

7. The sprayer should be winterized before storage by pumping a 50-50 solution of water and R. V. antifreeze through the entire plumbing. Proper care and maintenance will prolong the life of the sprayer.
