Spraying Setup
1.
Securely hitch the sprayer to the tractor and fasten
the safety chain. Make sure the hitch is adjusted for
1-2
forward tilt of the tank (front of sprayer tank
frame is about 1
1
2
in {3.8cm} lower than the rear) so
that liquid in the tank will drain to the sump.
2.
Fill sprayer tank half full with clean water for
calibrating purposes.
3.
Hook-up the pump to the tractor. Engage the pump
slowly and check for any leaks.
4.
Set the deadhead pressure of the pump at 80 psi
depending on how the pump is driven. See
or
below.
5.
Calibrate sprayer. See
Hydraulic Pump Setup
1.
To determine the correct flow rate to the hydraulic
motor, start with the hydraulic control valve set at a
minimum flow, and the hydraulic lever in the float
position.
2.
Open up the sprayer control valve to its maximum
setting. (On the Raven SCS 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.)
3.
Start the tractor and engage the pump by placing the
hydraulic lever in the down position. Once the
system builds pressure on the nozzle pressure
gauge, speed up the tractor throttle to normal
operating speed. Shut off the boom section switches
and close the agitation valve.
4.
The pump is now at deadhead pressure and the
hydraulic control valve must be adjusted up until the
spray pressure reaches 80 psi maximum on the
nozzle pressure gauge. Mark this setting on the
hydraulic control valve for future reference.
5.
Open up the agitation valve.
PTO Pump Setup
1.
Open up the sprayer control valve to the maximum
setting. (On the Raven SCS 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 sec-
onds.)
2.
Start the tractor and engage the PTO pump slowly
with the tractor engine idling. Once the system builds
pressure on the nozzle pressure gauge, shut off the
boom section switches, and close the agitation valve.
3.
The pump is now at deadhead pressure. Increase
the engine rpms until the spray pressure reaches
80 psi maximum on the nozzle pressure gauge or
the PTO speed reaches the rated rpm (540/1000).
Never exceed the rated tractor PTO rpm. This is the
rpm needed to spray at to prevent excess pressure
on the sprayer’s plumbing.
4.
Open up the agitation valve.
Manual Throttle Valve
When the manual throttle valve is full open (valve
in
Figure 28 on page 41), the pressure adjustment can be
very sensitive. The butterfly valve
has to move more
often causing additional wear.
To decrease the sensitivity, set the manual throttle
adjustment valve as follows:
1.
Open the throttle valve so that it is wide open and
there is full flow to the sprayer booms. Open the but-
terfly valve until it is full open.
2.
Close the throttle valve down until the pressure is
about 20 psi greater than the pressure you intend to
spray at. Spraying pressure is determined when
calibrating sprayer. Refer to the
Application Guide
.
With this valve set, it decreases the flow through the
electric ball valve and reduces the sensitivity of the
pressure adjustment switch.
