Operation Instructions
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 noz-
zles 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 handle is to be tightened to increase pressure and loosened to decrease pres-
sure. The 'directo-valve' is the on/off control which allows the operator to manually control the solution going to the boom.
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 important to test the sprayer with plain water before actual spraying is attempted. This will enable you to familiarize
yourself and 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
The performance of any agricultural chemical depends upon the proper application.
Always fill the tank with a desired amount of water first and then add the chemical slowly, mixing as you pour the chemical into
the tank. You may use the handgun to spraying into the solution in order to mix the chemical and water.
Only fill the tank with what you're going to spray in a day, never leave chemicals sit in tank.
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 pumping system draws solution from the tank through the strainer/filter and to the pump. The pump forces the
solution under pressure to the boom nozzles.
