Operation
Before operatingsprayer, readthe tractor
operator’smanual andgainan
understanding of its safe methods of
operation.
Check the tractor brakes and warning
lights. Make sure they are in proper
working order.
Check the tractor hydraulic oil reservoir
and add oil if needed.
Verify that the tractor is adequately
ballasted for drawbar operation at the
anticipateddraftand verticaltongue load.
Vertical tongue loadof aloaded sprayer
(with boomsfolded totransport position)
isapproximately 5000lbs. Ensure that
thetractor’sdrawbarhassufficient
strength to support thisload.
Ifpossible,adjustthetractordrawbar
verticallyso thetop sideof thedrawbar is
atleast 18inchesfromtheground.
Alternately, the sprayer hitch may be
adjusted vertically by choosing other
mounting holes provided.

tooperation.
•Inspection
Performtheservicechecksasoutlined
below. Repair or replace any damaged
orworn parts before operating.
Boom Rest Set-up: Refer to page 4-2
for initialboomrestset-up procedures.
Hardware: Check for loose bolts and
nuts, and tighten as needed. Check
again after the first half-day of operation.
Pivot Pins: Check that all pins are in
place and in good condition. Replace
any worn, damaged, or missing pins.
Hydraulic System: Check all hoses and
cylinders for signs of leakage. Hoses
should not be kinked, twisted or rubbing
againstsharpedges. Rerouteor repair
hoses as necessary. Refer to SAFETY
section for additional information on
safe repair and inspection of hydraulic
components.
Tires/Wheels: Check tire pressures and
maintain at recommended values listed
in the MAINTENANCE section of this
manual. Maintain 500 lb-ft. torque for
the 7/8" wheel lug bolts.
CAUTION: Frequentlycheck the
torque ofall wheel lug nuts, particularly
during the initial transport and operation
ofthisimplement. Ifa lugboltorstud
becomes loose,this mayresult inthe loss
of a wheel and subsequent loss of control
ofthe tractor and/or sprayer.

MAINTENANCE SECTION of this
manual.

2-3
Operation
WARNING: Do not stand between
the implement and tractor when
hitching. Serious or fatal injury can
occur due to crushing hazard from
limited clearance between tractor and
implement. Always engage parking
brake and stop engine before inserting
hitch pin.
Connect the drawbar hitch only to the
tractordrawbar. Donotattemptto hitchto
any other location on the tractor.
Thesprayer isequipped standardwith a
clevishitch,whichrequiresa1 ¼”
drawbar pin. This hitch can be converted
to a single tang style by unbolting and
removingtheclevis. Whenusedasa
singletang style,a 1½” diameter
drawbarpin mustbe used.
NOTE: The useof a smaller diameter
hitchpin will result in additional clearance
between the implement hitch and pin.
Thisadditional clearancemay cause
acceleratedpin andhitch wear,alongwith
morepronouncedjoltingfromthesprayer
duringoperation.
Afterinserting drawbar pin, secure with a
locking device to helpprevent uncoupling
during use.
•2-Point Hitch (Optional)
Theoptional 2-pointhitchis compatible
with Cat III-N, CATIII andCATIV-N
hitches. Verifyhitchpinsize compatibility
priorto hitching.
After couplingto tractor,raisesprayer

HITCHING TO TRACTOR
•Drawbar Connection
Verify and/or adjust the sprayer hitch

Operation
NOTE: The sprayer pumpis hydraulically
driven, and needs tobe configured
correctly to match the type of hydraulic
systemon thetractor(closedcenter, open
center,loadsensing,etc.). Failureto
configure the pumpcorrectly may
permanentlydamage the pump through
over-speeding. Refertothe
MAINTENANCE SECTION of this
manual for guidelines on configuring the
sprayer pump.
Connecthoses fromthe sprayerpump to
a tractorselective controlvalve (SCV)
circuit. The pump inlet (marked PUMP
PRESSURE) should be connected to
the RETRACT port and the pump outlet
(marked PUMP RETURN) to a low
pressure return port at the tractor
(recommended) orto theEXTENDport.
•Revised011405
•Transport Chain Connection
(Drawbar Style Hitch Only)
Tractor must be equipped with a
transport chain support. Attach chain in
manner illustrated. Adjust the chain
length as necessary to eliminate
excessive slack, while preventing
binding during tight turns.
CAUTION: Always use a properly-
sizedtransportchain between sprayer
andtractor. Failuretousetransportchain
could result in personal injury or property
damage ifimplement andtractor become
disengagedduringoperation.

•Hydraulic Connections
After cleaning hydraulic hose couplers,
connect to tractor hydraulic circuits as
follows:
Sprayer Pump Hydraulics

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: Ifthe SCVcontrol leverkicksout
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 thisinstance, attach
to the three power beyond couplers on the
tractor, or change thehydraulic valve
attachtothethreepowerbeyondcouplers
onthe tractor, or changethe hydraulic
valve setupfor usewithan SCV circuit.
Refer tothe MAINTENANCESECTION
for valvesetup information.
Toprotectthesprayerpumpfrom
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 OPERATION
WARNING: Keep all personnel a
safe distance away from the sprayer
when unfolding or folding the boom.
Personal injury can result from
impact with boom.
WARNING: Perform boom
unfolding and folding operations only
in areas with adequate height, width
and length clearances. In particular,
be mindful of location of overhead
power lines. Failure to do so can
result in personal injury and property
damage.
1. Press top of ON/OFF switch to turn
power on. (Red LED lamp on rocker
switch should illuminate. Green LED
lamp is provided to indicate circuit
continuity whenever any other switch
is pressed.)
2. Press and hold MAIN BOOM switch
in <RAISE> position until boom is
fully raised. This ensures that the
transport latch is not supporting the
weight of the boom.
3. Press and hold RH WING TILT and
LH WING TILT switches in <UP>
position until wings are fully tilted
upward. Note: Wing tilt function
may require several seconds of use
before wings begin to move.
4. Press and hold INNER WING switch
in <EXTEND> position until wings
are fully extended and wing locks are
engaged on lock pins.
5. Momentarily press WING TILT
switches either <UP> or <DOWN>
