7. At this time tighten all bolts starting with the bolts in  
10. Assemble the boom bars to the boom mount bracket  
using two 5/16" x 1-1/4" carriage bolts, tooth lock  
washers (between the bar and bracket), 5/16" flat  
washers and knobs. The boom connecting hose  
should extend upward. See figure 6.  
figure 2, then the bolts in figure 3.  
8. Install the drain in the rear of the tank as shown in  
figure 4. Place a 3/4" garden hose gasket onto the  
drain body and insert the drain body out through the  
hole in rear of the tank. 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.  
NOTE: Make sure the nozzle openings face straight  
down when the boom bars are in the horizontal  
operating position.

12. Insert a garden hose gasket into the swivel nut on  
the bypass/return hose. Screw the nut onto the  
upper outlet of the "Y" valve fitting. Place the other  
end of the hose down through the hole at the rear  
of the tank. 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.  
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.  
IMPORTANT: This sprayer should be connected to 12  
volt batteries only!  
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

USING THE SPRAYER  
OPERATION  
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.  
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.  
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.  
PUMP PRESSURE SWITCH  
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.  
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.  
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 run-  
ning 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.  
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.  
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.  
ON-OFF ADJUSTMENT OF BOOM NOZZLES  
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.  
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.  
9. Stay clear of flowers, shrubs and evergreen trees  
when spraying weed control solutions to prevent  
contact of the solution with these sensitive plants.  
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.  
CAUTION: WEAR EYE PROTECTION,  
GLOVES AND PROTECTIVE CLOTH-  
ING WHEN HANDLING AND WORKING  
WITH LAWN CHEMICALS.  
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.  
40"  
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.

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 hand-  
gun 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 manu-  
facturers 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.
