Operation
hydraulic circuit. When the circuit is
energized, oil will circulate constantly
through the sprayer hydraulic valve.
Because of this, it is important to
minimize the flow through this circuit.
Adjust the tractor SCV flow control to
the lowest setting that still allows the
boom functions to operate at an
acceptable speed.
Doing so will keep
any oil heating to a minimum, and allow
other SCV circuits to operate normally.
Note: If the SCV control lever kicks out
prior to actuating any switch on the
boom control box, the most likely reason
is excessive hydraulic pressure. Try
reducing the tractor’s flow control
setting. Also, excessive pressure can
also occur if the hydraulic valve has
been modified for use with power
beyond systems. In this instance, attach
to the three power beyond couplers on the
tractor, or change the hydraulic valve
attach to the three power beyond couplers
on the tractor, or change the hydraulic
valve setup for use with an SCV circuit.
Refer to the MAINTENANCE SECTION
for valve setup information.
To protect the sprayer pump from
damage due to excessive speed, adjust
circuit flow to minimum setting prior to
operating circuit for the first time. When
in operation, adjust flow per instructions
listed under the “Basic Sprayer Settings”
heading in this section.
IMPORTANT: Never operate sprayer
pump dry, or with PUMP INLET
SELECTOR valve closed. Pump
damage may result.
Boom Hydraulics
CAUTION: Do not unfold or fold
boom without hitching to the tractor.
The wing-fold hydraulic system on this
sprayer is configured to connect to a
tractor SCV valve, but can also be
modified to operate with power beyond
circuits of tractors with a load-sensing
hydraulic system (Refer to the
MAINTENANCE SECTION for
information on converting to a power
beyond circuit).
Connect the hose marked BOOM
PRESSURE to the EXTEND port of one
of the tractor SCV circuits, and the hose
marked BOOM RETURN to the
RETRACT port of the same circuit.
