SECTION 3 - SPRAYER OPERATION
3.4 TESTING AND ADJUSTMENT OF SPRAYER SYSTEM
1. ADD WATER TO MAIN TANK
Add approximately 150 gallons of water to main tank through optional bottom fill kit or through top fill well. With water
in the tank verify that tank straps are secure.
2. PRIME SPRAYER SYSTEM PUMP
a. Prime PTO driven pump
1. Engage tractor PTO system and increase to normal field PTO speed in order to circulate water from the
tank to the pump and back to the tank again through the agitators. Immediately verify agitator flow by
looking through top fillwell.
2. Disengage tractor PTO system.
b. Prime hydraulically driven pump:
1. Engage tractor hydraulic system and increase to normal field rpm speed in order to circulate water from the
tank to the pump and back to the tank again through the agitators. Immediately verify agitator flow by
looking through top fillwell.
2. Disengage tractor hydraulic system by moving hydraulic lever to float position. This allows pump to coast
to a stop.
3. ADJUST HYDRAULICALLY DRIVEN PUMP SYSTEM
The hydraulically driven pump system must be adjusted to produce a maximum pressure of 80 psi in order to stay
within the 0 to 150 psi operating range of the plumbing system.
a. Adjust CLOSED CENTER pump:
1. Loosen jam nut for bypass screw located on top of hydraulic mo-
tor and turn screw completely in. Secure jam nut.
2. Adjust flow control valve for tractor hydraulic system to allow mini-
mum oil flow.
3. Close agitator control ball valve and verify boom switches are off.
LEAVE MAIN SUPPLY VALVE OPEN!
4. Engage tractor hydraulic system and increase to normal field RPM
speed.
5. Adjust flow control valve for tractor hydraulic system until pres-
sure gauge reads the recommended maximum pressure of 80
psi.
6. Disengage tractor hydraulic system by moving hydraulic lever to “float” position. This allows pump to coast
to a stop.
7. Setup Normal Spraying.
b. Adjust OPEN CENTER pump:
1. Loosen jam nut for bypass screw located on top of hydraulic motor and turn screw out 3 revolutions
from factory setting.
2. Close manual agitator control valve and verify booms switches are off. LEAVE MAIN SUPPLY VALVE
OPEN!
