3.4 TESTING AND ADJUSTMENT OF SPRAYER SYSTEM
. 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. TEST OPTIONAL MIX AND FILL KIT WITH BUILT-IN BOTTOM FILL
a. Test Drawing Chemical
1. Add approximately 15 gallons of water to mix and fill tank.
2. Start engine and activate pump.
3. Setup Drawing Chemical by opening ball valve on chemical tank. Partially close
main supply valve to draw chemical. When chemical tank is empty OPEN MAIN
SUPPLY VALVE FULLY TO KEEP FROM RUNNING PUMP DRY.
IMPORTANT!
NEVER ALLOW PUMP TO RUN DRY. SEALS WILL BURN UP IN LESS THAN 15 SECONDS
WITHOUT LIQUID TO RUN IN. THIS DAMAGE IS NOT COVERED UNDER WARRANTY.
3. START-UP RAVEN CONTROL
a. Start-up Raven SCS-205 Control:
1. Place all BOOM ON/OFF switches to OFF.
2. Place MASTER ON/OFF switch to ON.
3. Start pump drive engine and increase to normal field rpm speed
4. Alternate each BOOM ON/OFF switch to on and verify that respective boom ball
valve operates and that all nozzles on that section are spraying including end nozzle,
if equipped.
5. With all BOOM ON/OFF switches to on, hold the manual pressure adjust switch
one way and then the other to learn maximum and minimum spray pressures, with
and without agitation. The regulator valve is fully closed when the pressure is at its
lowest reading. The motorized regulator valve rotates slowly clockwise or counter
clockwise depending on switch position and could take up to 90 seconds to go from
fully open to fully closed position.
6. Adjust manual agitator control valve.
a. Partially close agitator control valve to increase maximum operating pressure.
b. Under most spraying conditions, agitator control should be fully open. If
operator wishes to empty tank completely the agitator should be closed on last
spray pass.
7. If maximum operating pressure is still too low, verify that there is sufficient engine
speed and that main line strainer screen is not obstructed.
b. Start-up Raven SCS-450 Control:
1. Complete instructions for the SCS-450 Sprayer Control are provided in the SCS-
450 INSTALLATION AND SERVICE MANUAL which is included in the sprayer
console box.
