(60 Gallon 3 Point Sprayer
w/7-Nozzle Boom Assembly)
Information About the Sprayer
Roller pumps are positive displacement pumps, which means
that the entire solution being pumped must go somewhere or
the pump will break. In this roller pumping system, solution is
drawn from the tank and forced to a planned source, such as
boom nozzles or handgun. The pressure is controlled by a
pressure relief valve, which is a spring-loaded device that
controls the amount of fluid bypassed (recirculated) to the
tank. The gray adjusting cap is to be tightened to increase
pressure and loosened to decrease pressure.
The ‘directo-valve’ is the on/off control which allows the oper-
ator to manually control the solution going to the boom.
Assembly Instructions
Most of the sprayer has been assembled at the factory.
Join the center boom member to the carrier frame with the (2)
U-bolts and (4) whiz nuts provided. See exploded view later
in this manual for reference.
Attach the boom feeder hose to the boom after routing it
through the underside of the carrier frame as needed. Secure
in place with a hose clamp provided.
Poly hose fittings (5010209) are included to be joined to the
pump. A torque chain, ‘S’-Hook and hardware are also in-
cluded for the pump. The pump IS NOT included with this
unit. It is intended for a pump to be mounted directly to the
tractor PTO.

IMPORTANT: Remove tank lid and be sure the tank is
clean and free of any foreign material. Rinse tank out
of any tank residue before filling with water to test.
Testing the Sprayer
Attach the sprayer to the tractor 3 point hitch. Mount the pump to the
PTO and affix the torque chain.
NOTE: It is VERY important for to test your sprayer with plain water
before actual spraying is attempted. This will enable you to check for
leaks without the possibility of losing any expensive chemicals.
Fill the tank about 1/2 full with plain water.
Before starting, open the suction line valve (located underneath the
carrier frame), turn the relief valve handle out to lower the line
pressure. This will help prime the pump.
CAUTION: Always be sure that the water (or solution) has reached
the pump before starting your sprayer. If the pump is allowed to run
dry, serious damage to the pump will result.
Always have the pressure line open to the tips so that the air which
may be trapped in the line will be forced (or purged) out.
Start the tractor PTO. Check the entire system for leaks. Once the
pump is primed, the pressure may be increased by turning the
handle of the pressure relief valve in. Keep the pressure line open to
the tips when setting the pressure. Set the pressure and then lock
the relief valve handle in place. Shut off the directo-valve and check
for leaks again. Pressure will increase when the pressure line valve
is closed and then return to the preset pressure when the valve is
opened again.
During the testing period, be sure to observe the spray pattern given
by the spray nozzles. If there is any pattern distortion, it will be
necessary to remove and clean the affected tips.
Caution: Never use a metal object or other sharp item for cleaning a
nozzle tip. It is better to use a nozzle brush (NOT wire brush) or
compressed air for tip cleaning.
Conditions of weather and terrain must be considered when setting
the sprayer. Do not spray on windy days. Protective clothing must be
worn in some cases
Be sure to read the chemical label(s) before application!
Operation & Calibration
The performance of any agricultural chemical depends upon the
proper application.
The tips supplied as standard with the sprayer can be used for a
wide variety of spraying applications. Other tip sizes are available for
different coverages. The speed and pressure charts shown indicate
the rates can be changed considerably by changing speed and
pressure. The nozzles on the boom will spray a 140” wide swath. The
proper nozzle height is a minimum of 17”-20” above the object being
sprayed. The pumping system draws solution from the tank through
the strainer/filter and to the pump. The pump forces the solution
under pressure to the handgun and/or boom nozzles.
 Activate the handgun by squeezing the handle lever
 Rotating the adjustable nozzle tip on the handgun will change
the tip pattern from a straight stream to a cone pattern (fine
mist)
WARNING: Some chemicals will damage the pump valves if
allowed to soak untreated for a length of time! ALWAYS flush the
pump as instructed after each use. DO NOT allow chemicals to sit in
the pump for extended times of idleness. Follow the chemical
manufacturer’s instructions on disposal of all waste water from the
sprayer.
When you are ready to spray, mix chemicals as follows. Add the
proper amount of water to the tank. Run the sprayer while adding
chemical to the water. Do NOT spray through the boom at this time.
This will allow the solution to return (‘bypass’) to the tank. The
movement of solution through the bypass will aid in mixing the water
and chemicals. If this water movement is not enough to keep the
chemical in suspension, it may be necessary to add an optional
agitator kit. You should now be ready to spray.
Four things must be considered before spraying with the boom.
 How much chemical must be mixed in the tank.
 Rate of spray (gallons per acre to be sprayed).
 What pressure (p.s.i.) will be used.
 Speed traveled (mph) while spraying.
 Refer to the chemical label to determine your chemical mixture
 See the tip chart to determine the pressure to be used. The
chart will also show the speed used when spraying.
Chemical labels may show application rates in gallons per acre,
gallons per 1000 square feet or gallons per 100 square feet. You
will note that the tip chart shows 2 of these rating systems.
Once you know how much you are going to spray, then determine
(from the tip chart) the spraying pressure (PSI), and the spraying
speed (MPH). The pressure can be set by running the sprayer with
the boom nozzles ‘on’ and then adjusting the relief valve until the
gauge reads the desired pressure. Notice that the pressure will go
up when the boom line is shut off. This is normal and the pressure
will return as before when you open the boom line. When selecting
pressure from the tip chart, it is a good idea to try for the 20 or 30
p.s.i. range as this allows an excellent nozzle pattern. Spraying at
10 p.s.i. begins to break up the pattern and at 40 p.s.i. you may
notice some drift.
Determining the proper speed of the pulling vehicle can be done by
marking off 100, 200 & 300 feet. The speed chart indicates the
number of seconds it takes to travel the distances. Set the throttle
and with a running start, travel the distances. Adjust the throttle until
you travel the distances in the number of seconds indicated by the
speed chart. Once you have reached the throttle setting needed,
mark the throttle location so you can stop and go again, returning to
the same speed.
Add water and proper amount of chemical to the tank and drive to
the starting place for spraying.

A torque chain, ‘S’ hook, nut and bolt are included in this assembly
to secure your pump during operation.
1. Attach one end of the torque chain over the threaded stem of
the bolt
2. Thread the whiz nut onto the bolt. Hand-tighten
3. Thread the bolt, chain and nut ‘pre-assembly’ into the threaded
hole on the underside of the pump. Tighten sufficiently
4. Affix the ‘S’ Hook to your frame (or hitch). Wrap the chain
around the frame or hitch and ‘S-Hook’ it in place. Make sure
this connection is very secure! Not having a good, tight con-
nection may result in the pump spinning on your PTO shaft
and damaging some components of your sprayer
*** Insure that this connection point will not allow the roller pump to
spin on the PTO shaft ***
Torque Chain Attachment to a Roller Pump
Maintenance During/After Spraying
Periodically check the strainer and clean the screen on your intake
line.
Proper care and maintenance will prolong the life of your sprayer.
After use, fill the sprayer half way with clean water. Start the pump
and allow the water to pump through the entire plumbing system and
nozzles. Drain and then refill half full, add the recommended amount
of a good quality tank cleaner, such as FIMCO Tank Neutralizer and
Cleaner. (If no tank cleaner is available, you may substitute dish
soap for this step). Turn pump on and circulate through system for
15 minutes and then spray out through boom and handgun nozzles.
Refill sprayer half way with clean water and repeat. Follow the chemi-
cal manufacturer’s disposal instructions of all wash or rinsing water.
If boom or handgun nozzles need cleaning, remove them from the
sprayer and soak in warm soapy water. Clean with a soft bristled
brush or toothpick if necessary. Never use a metal object. Even the
slightest damage can change the flow rate and spray distribution.
Water rinse and dry the tips before storing.
WARNING: Some chemicals will damage the pump valves if al-
lowed to soak untreated for a length of time! ALWAYS flush the
pump as instructed after each use. DO NOT allow chemicals to sit in
the pump for extended times of idleness. Follow the chemical manu-
facturer’s instructions on disposal of all waste water from the sprayer.
Winter Storage
Drain all water out of your sprayer, paying special attention to the
pump, handgun and valve(s). These items are especially prone to
damage from chemicals and freezing weather.
The sprayer should be winterized before storage by pumping a solu-
tion of automotive antifreeze (containing a rust inhibitor) through the
entire plumbing system. This antifreeze solution should remain in the
plumbing system during the winter months. When spring time comes
and you are preparing your sprayer for the spray season, rinse the
entire plumbing system out, clearing the lines of the antifreeze
solution.
Proper care and maintenance will prolong the life of your
sprayer.
