SECTION 3 - SPRAYER OPERATION
3. Engage tractor hydraulic system and increase to normal field
rpm speed.
4. Slowly turn bypass screw in until pressure gauge reads the
recommended maximum pressure of 80 psi. Secure jam nut.
5. Disengage tractor hydraulic system by moving hydraulic lever
to “float” position. This allows pump to coast to a stop.
6. Setup Normal Spraying.
4. 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.
NOTE!
IN SITUATIONS WHERE THE TRACTOR IS EQUIPPED WITH A FLOW CONTROL IT WOULD BE ADVANTA-
GEOUS TO CONTROL THE PUMP WITH THIS METHOD. IF THE BYPASS SCREW METHOD IS USED IT WILL
USE MORE HYDRAULIC FLOW. THIS WILL GENERATE HEAT AND CONSUME POWER.
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.
5. 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
