Preparing Sprayer for Operation
Add about 10 gallons of water to the spray tank. Do not
add any chemical until the sprayer has been checked for
proper operation. Do not install spray tips in the nozzle
bodies until the lines have been flushed.
Open the suction valve located beside the line strainer.
(Ball valves are open when the handle is in line with the
hose attached to the valve.) Check for any leaks from the
tank to the pump. Any fluid leak on the suction side of the
pump will result in an air leak when the pump is started.
Check to see that the Hypro control valves are in the “off”
position (see Figure A5). Engage the PTO shaft (or start
the engine) to start the pump. Water should be returning
to the tank through the return line.
In order to check the operation of the boom or boomless
nozzles, flip the valve handle “up” that supplies the boom.
Water should be flowing from the boom nozzles or the
boomless nozzle. Allow the water to flow for a few moments
to flush any debris from the lines.
Rotate the valve handle to open the valve that supplies the
trigger gun. Engage the trigger gun. Check for any leaks
in the sprayer system.
The operating pressure is set by adjusting the pressure relief
valve (green knob) located on the top of the Hypro control valve.
Tighten the pressure relief valve to increase the pressure.
Example: To set the pressure for the trigger gun, engage
the valve handle and the trigger gun. Note the pressure
gauge. To increase pressure, screw the pressure adjusting
knob “clockwise”; to decrease pressure, screw the knob
“counterclockwise”.
Maximum pressure for the 7560 Hypro pump is 300 psi.
Maximum pressure for the CDS/John Blue gear pump
is 200 psi. Do not set the pressure relief valve for a
higher setting than these recommended pressures.
Pump damage could result.
