11 Preparation and Setup
11. Fill sprayer approximately 1/2 full of water.
Open tank sump valve and let water circulate
throughout the system and check for any
leaks.
12. Before installing nozzles, engage pump
slowly and circulate water through the sys-
tem, then turn on boom valves individually to
flush out the system. (On sprayers equipped
with a hydraulic pump, start out with the hy-
draulic lever in the float position, and engage
the pump by placing the lever in the down po-
sition. Make sure the hydraulic flow control
valve is set at a minimum flow.)
13. After system has been thoroughly flushed,
install nozzles and open boom valves again
to check nozzle pattern across the boom.
14. Set the deadhead pressure of the pump in
the following ways depending on how pump
is driven.
Hydraulic Drive Pumps
a. To determine the correct flow rate to the
hydraulic motor, start out with the hy-
draulic control valve set at a minimum
flow, and the hydraulic lever in the float
position.
b. Open up the sprayer control valve to its
maximum setting. (On the Raven 440
monitor, with the power switch on, the
rate switch must be placed in the manual
position, and the increase/decrease
switch must be pushed to increase for
10-12 seconds).
c. Start the tractor and engage the pump
by placing the hydraulic lever in the
down position. Once the system builds
pressure, speed up the tractor to normal
operating speed. Shut off the boom sec-
tion switches, and close the agitation
valve.
d. The pump is now at deadhead pressure
and the hydraulic control valve must be
adjusted up until the spray pressure
reaches 80 PSI maximum. Mark this set-
ting on the hydraulic control valve for fu-
ture reference.
e. Open up the agitation valve.
