ASSEMBLY
Tools Required: Philips Head Screwdriver, Pliers and Socket Wrench.
Most of the assembly has been completed during the manufacturing process. Only a few short steps are
required to complete your sprayer. Open the shipping carton and remove the contents. Follow the steps below
to assemble your 3-point sprayer:
Step 1) Locate screw holes on front of Sprayer Tank. With
Screws, install Gun Clips to the front of Sprayer Tank. Be
sure open end is facing top of the sprayer.
Step 2) Seat Drain Cap Gasket into Drain Cap. Attach Drain
Cap Tether to Top of Drain Cap. Place other end of Drain Cap
Tether over Drain Port. Thread Drain Cap onto Drain Port.
Step 3) Un-thread Tank Lid from Sprayer Tank. Insert
Tank Lid Tether from bottom of Tank Lid, “T” end
first. Pull Tank Lid Tether through top Tank Lid, so ball
end remains inside the Tank Lid. Thread Tank Lid back
on Sprayer Tank. Thread “T” end of Tether through
hole next to Tank opening.

Step 4) Wrap a small amount of Teflon tape around the
threads of the Pressure Gauge. Thread Pressure Gauge into
the top of the Pressure Regulator Assembly. Take care not
to cross-thread the Pressure Gauge. Note: Pressure Gauge
should be facing forward with Regulator Assembly knob.
Step 5) Slip the ½” Hose Clamp over the end of the
Spray Gun Hose. Push Spray Gun Hose onto the bottom
hose barb of the Pressure Regulator Assembly. Tighten
the Hose Clamp with Pliers.
Step 6) Place Fan Tip into Fan Nozzle Cap. Insert
Gasket into Fan Nozzle Cap. Then Place Nozzle Strainer
into Nozzle Assembly Port. Press Fan Nozzle Cap onto
Nozzle Assembly Port. Twist to Lock.
Repeat this step for the other remaining Nozzle
Assembly Ports.

Step 6) Place 1” Bolts through Boom Assembly and into
the Boom Brackets on the rear of the frame. Secure with
Flange Nuts and tighten with a Socket Wrench.
Step 7) Locate Boom Hose and make sure there is a
Washer in the end of Boom Cap. Thread the Boom Hose
to the Shut-Off Valve. Note: Use a knife to cut zip tie
from Boom Assembly to free the Boom Hose.

WIRING HARNESS
Before spraying chemicals, fill the tank half full of plain water to allow familiarization
with the sprayer and to prevent waste of expensive chemicals.
Operating power is obtained
directly from a 12 VDC
source. Be sure to connect
the red to the positive (+)
source and attach the black
to the negative (-) source.
IMPORTANT

OPERATION
!! IMPORTANT !! –It’s important to test the sprayer with plain water after assembly and any extended
period of storage. This will allow you to check for leaks without wasting expensive chemical or damaging
an area that you’re trying to spray.
Attach the sprayer to a tractor, then fill the tank approximately ½ full with water and connect the wiring harness
to a 12VDC source.
Ensure the boom valve is in the closed position, then turn the wiring harness switch to the ON position. The
pump should run for a short period of time until the pump is primed then automatically turn off. KEEP THE
SWITCH ON TO PERFROM THE FOLLOWING TESTS. Check for any leaks and make repairs if necessary.
Using the spray wand, ensure the nozzle is pointed down and away from yourself or others, then cycle the
trigger on the spray gun a few times until water sprays out from the nozzle consistently. Release the trigger and
confirm the pump comes up to pressure and stops. Locate the spray boom valve and turn the valve to the open
position. Confirm the booms spray pattern is facing down and even from side to side. Adjust nozzle position as
necessary. Turn off the spray boom valve. Once again, the pump should come up to pressure and shut off.
Check the entire system for leaks and make any necessary adjustments. Turn the power switch to the off
position.
Your sprayer is equipped with an inline switch located in the wiring harness. This switch is used to operate the
pump on or off.
There is also a secondary switch located in the pump. This switch is designed to turn the pump off when it
reaches 40 psi. This switch is calibrated at the factory and should not be tampered with.
Ensure the basket strainer is in place and fill the tank with the desired amount of water based on the amount of
solution needed. Measure out the chemical required for the amount of fresh water in the tank as specified by the
chemical label. Slowly pour the chemical into the tank while mixing. Initially you can remove the basket
strainer and use the spray gun to spray back into the tank to help the mixing process and purge mixed solution
through the pump and spray wand hose. Make sure you replace the basket strainer when done.
Using the handgun
-Ensure the power switch is in the on position.
-Begin spraying by pointing the spray nozzle toward the ground and squeezing the handle lever. The
pump will turn on automatically.
-The spray pattern exiting the nozzle can be adjusted from a straight stream to a cone pattern by rotating
the nozzle.
Using the spray boom
-Ensure the power switch is in the off position.
-Pull the sprayer to the location you would like to spray and turn the boom valve to the on position.
-Begin pulling the sprayer at the desired MPH (See calibration section) and turn the power switch to the
on position. The pump will start to run and the boom will begin spraying.
-Use the power switch to cycle the pump between spraying and stopping.
-When spraying in rows it is common practice to overlap your spray pattern by 50% to ensure
consistent chemical delivery.

CALIBRATION
Fan Spray Nozzles: The Fan Spray Nozzles on the boom will spray an 156” swath. The nozzle height should
be approximaetly 15” above the objext being sprayed.

Once you know how much you are going to spray, determine (from the top chart) the spraying pressure(PSI)
and the spraying speed (MPH)
When selecting pressure from the top chart, it is a good idea to try for the 30 PSI range as this allows and
excellent nozzle pattern. At 10 PSI the pattern begins to break up and at 40 PSI you may notice some drift.
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 cehmical label carefully.
After all calibrations have been completed, add water and chemical to the tank. Always follow chemical
manufacturer’s instrautions for mixing. 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
cehmical label carefully.

CLEANING & STORAGE
Spray materials can be highly toxic. Make sure to read and follow all warning labels.
Most spray materials are highly corrosive. The most important aspect of long, dependable
service from the sprayer is a thorough cleaning immediately following each use. In addition, the residue of one
type of chemical could cause an undesirable effect when a different chemical is used for a different purpose.
The most effective cleaning method is to pump several rinses of clean water through the tank, pump, hoses,
boom, spray gun, etc. A neutralizing agent such as a solution of Nutra-Sol, a detergent or household ammonia,
as recommended by the chemical manufacturer, can assist in removal of a persistent chemical. When the
system is thoroughly cleaned, drain the tank, suction line, pump, hoses, etc.
The following steps should be followed for the maintenance and storage of your sprayer.
1. Wash and flush out sprayer after completion of each phase of your program. Flush out sprayer when
changing chemicals if there is a possibility of the chemicals being incompatible. Use of a detergent
is advisable if the chemical manufacturer does not make specific cleaning recommendations.
Flush system completely, including nozzles. Never use metal objects to open clogged nozzles.
2. Clean sprayer thoroughly before storing at the end of the spraying season. Permanent type anti-
freeze added to the final rinse will leave a rust inhibiting film in parts of the sprayer.
