Predelivery
1. Have tractor delivered to dealership that will be
operating sprayer.
2. Confirm row spacing.
3. Hook sprayer to tractor.
4. Install control switch boxes inside of tractor cab, and
route power supplies to the tractor battery.
5. The following equipment must be connected to the
tractor’s battery: Raven 440/450 Controller, Fasse
Valve Hydraulic Control Box, and Optional Foam
Marker Control.
a. To connect the Raven 440/450 Controller to the
tractor battery, see pages 7 and 8 in the Raven
Installation and Service Manual.
b. To connect the Fasse Valve Hydraulic Control
Box, follow the steps below.
i. Use 6 ft, two-wire red and black cable to
connect hydraulic controls.
ii. Connect red wire from each cable to posi-
tive terminal and black wire from each cable
to negative terminal.
c. Use 6 ft gray cable to connect the Optional
Foam Marker Control to the tractor’s battery.
6. Mount radar gun to tractor frame if applicable and
route cable up through cab. If using existing radar
on tractor, install “Y” cable according to tractor man-
ufacturer’s recommendations.
7. Connect all hydraulic hoses to outlets (refer to trac-
tor operator’s manual for designated outlet if
equipped with a hydraulic pump). The hydraulic
motor used on all liquid pumps is a 6 GPM motor. If
the tractor used on this sprayer does not have the
capabilities to adjust the remotes to this flow, then a
hydraulic flow divider kit must be installed so that
flow can be controlled and to prevent operating the
pump at excessive speeds. Place a stop in the neu-
tral position for the tractor hydraulics so that the
hydraulic lever can only be moved to the float and
down positions. Refer to the tractor’s operator man-
ual on information for the neutral stop.
IMPORTANT !
Damage to the pump will occur if the hydraulic lever
is returned to the neutral position while the pump is
running.
8. Check all hydraulic functions of the boom/elevator.
9. With boom still unfolded, make sure boom locks are
adjusted correctly to just clear the stops.
10. Fill sprayer approximately 1/2 full of water. Open
tank sump valve and let water circulate throughout
the system and check for any leaks.
11. Before installing nozzles, engage pump slowly and
circulate water through the system, then turn on
boom valves individually to flush out the system.
(On sprayers equipped with a hydraulic pump, start
out with the hydraulic lever in the float position, and
engage the pump by placing the lever in the down
position. Make sure the hydraulic flow control valve
is set at a minimum flow.)
12. After system has been thoroughly flushed, install
nozzles and open boom valves again to check noz-
zle pattern across the boom.
13. Set the dead head pressure of the pump in the fol-
lowing ways depending on how pump is driven.
Hydraulic Drive Pumps
a. To determine the correct flow rate to the hydrau-
lic motor, start out with the hydraulic control
valve set at a minimum flow, and the hydraulic
lever in the float position.
b. Open up the sprayer control valve to its maxi-
mum setting. (On the Raven 450 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 plac-
ing the hydraulic lever in the down position.
Once the system builds pressure, speed up the
tractor to normal operating speed. Shut off the
boom section 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 P.S.I. maximum.
Mark this setting on the hydraulic control valve
for future reference.
e. Open up the agitation valve.
