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"fittingcontainingabypass
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.

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

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.
