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. Determinetheapproximatesquarefootageoftheareato  
besprayedandestimatethenumberofgallonsrequired.  
This can help avoid unneeded solution left in the tank.  
on-oFF swITCH  
This switch is connected in line to the wiring assembly and  
is used by the operator to turn the pump motor on or off.  
3. Determinetheappropriatespeedatwhichtotravel,based  
on the chosen pressure setting and the recommended  
application rate. Use the tip chart on page 9.  
PumP Pressure swITCH  
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.Setthethrottleand,witharunningstart,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.  
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  
notaproblemunlessthepumpissubjecttocontinuouscycling  
within one second intervals for long periods of time.  
aDJusTInG oPeraTInG Pressure  
5. 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  
beginstobreakup,at40PSIsomedriftdevelops.)Refer  
to the tip chart on page 9.  
Thesprayerisequippedwitha"Y"ttingcontainingabypass  
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. Add the chemical solution to the tank, following the  
product instructions.  
7. Drive to the starting place for spraying. Set the boom  
in position for spraying. Set the throttle at the position  
determined in step 4. Flip the sprayer's in-line switch to  
the "ON" position to start spraying.  
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.  
8. 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.

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 10.

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.

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

6. Drain all water out of the sprayer, paying special  
attention to the pump and handgun. These items are

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