sectionsto thecam-lock malefluid connectors(2) with
the hose clamps provided. Make sure to route the
boom hoses behind the boom break awaypivot (Figure 1 (4)) so that when the boom foldsto the back, the
hoseswill not stretch. Youwill need to route the hoses
from your tractor to the cam-lock female fluid connectors (3), which fasten into the stationary male fluid
connectors mounted on the 3-point frame.
6. If the 3-point boom is being mounted on a tractor with
Great Plains side-mount tanks, removethe cap plugs
on the solenoid hose barbs and route the left boom
feed-line hose from the corresponding female fluid
connector to the right solenoid {right being as you sit
in the tractor} marked with red tape. Connect the center boom feed-line hose from the corresponding female fluid connector to the middle solenoid marked
withyellow tape. Nowconnect the right feed-line hose
from the corresponding female fluid connector to the
left solenoid marked with green tape.Take care when
routing the boom hoses to the tractor to ensure there
willbe nokinking, drooping,hanging belowthe tractor,
orrubbing on thetractor frame whenin operation. Use
cable ties to fasten and protect the hose.
7. Fold and unfold the boom wings and check for any
pinch points where the hose may become damaged.
Unfoldthe boom, remove the boom level float lockpin
(Figure 1 (21)) and rock the boom to check any pinch
points around the swing bars (Figure 1 (20)). Use the
includedcableties tofasten thehoses insuch awayto
preventhose damage.
8. Check to see all nuts are tightened. See Torque Val-
ues Chart for Common Bolt Sizes in Appendix for additional torque specifications. Check to see that all
hose clamps are tight.
Fill the sprayer tank 1/4 full of water.Hook up the pump to
a tractor and operate the pump with the control box boom
switches off and the agitation wide open. If unit is
equipped with solenoid throttling valves open throttling
valves full open. With the pump running, turn on all the
boom switches and flush out the boom lines before assemblingthe nozzles.Allow water toflow out ofall nozzles
at least ten seconds to ensure all foreign matter is removed from the plumbing.

Operating Instructions
Basic Sprayer
Operating Procedures
1. Make sure to read the label on the chemical compound that is to be applied. It is the law.
2. Consider howthe chemical willbe stored andhow you
willdispose ofthe chemical,according tothe chemical
label.
3. When calibrating, filling the tank, or working around
chemicals, wear protective clothing that covers the
body. Referto WearProtective Equipment on page 5.
Have soap and clean water available to wash any exposed areas. Never open a container with your bare
hands.
4. When filling thesprayer,itis better to mixthe chemical
in the field where it is to be applied. Positionthe sprayer 100 feet from any well or other water source before
mixing chemical.
5. By law, you must repeat the rinsing of the chemical
container 3 times. The container should then be punctured to prevent future use. An alternative is to jetrinse or pressure rinse the container.
6. Check the condition of hoses and connections frequently. Release system pressure before working on
the sprayer by shutting off the pump and flipping the
individual boom section switches on the control box.
always wear rubber gloves when making repairs or
adjustments.
7. Apply spray when the wind is 5 m.p.h. or less. Minimizedrift byusing nozzletipswith thelargest practical
openings and by operating the sprayerboom at the
lowest practical height and lowest practical pressure.
Refer to Figure 7
8. After unfolding the boom, remove the level float pin
and place it in the storage position.
Operating Instructions
NOTE: If possible, do not operate your Great Plains
Sprayer boom without first unlocking the level-float
pin. The boom will float over the contours of the
ground more effectively and minimize stress on the
boom.
9. Drive at the same speed you used in your calibration.
Refer to SprayerCalibrations in the Sprayer Owner’s
Manual. Keep your sprayer calibrated.
10. If possible work crosswise to the wind, starting from
the downwind side of the field. Do this so you won’t
everbe heading directly into chemical fumes.
11. Take note of adjoining crops, houses, gardens, people, etc.
12. When you are finished spraying, empty the tank and
flush the sprayer with water, including the pump, the
nozzlesand the by-pass linefrom the solenoids. Properly store the chemical emptied from the tank or dispose of it by the recommendations on its label.
13. When turning at the end of a field, make sure you are
correct on the rows so that the boom will not overlap
on crop previously sprayed.
15
Parking
The following list should be followedwhen you want to unhook your boom.
1. Flush the boom out with antifreeze (Great Plains
strongly recommends the use of recreational vehicle
antifreeze)to preventdamage to components when a
freeze occurs.

Adjustments
Boom Height
After calibrating your sprayer for the specific nozzle you
will useatadesiredpressure,and tractor speed, the main
field adjustment is the boom height. Refer to Elevator Op-
tion in the Sprayer Owner’s Manual. Depending on which
type of nozzle you are using, you need to set your boom
height so that you achieve the correct overlap for that specific nozzle. If the crop canopy is taller in some fields than
others, you will need to adjust the boom height accordingly. Refer to the nozzle charts located in the SprayerOwner’s Manual or the Application Guide to determine the
height of the boom needed.
EXAMPLE: A 2.5 Metercone nozzle at 20 inch spacing is
being used. From the nozzle chart (refer to the Sprayer
Owner’s Manual or the Application Guide), a height of 19
to 21 inches above the top of the crop is required. If the
cropis6inchesoff the ground, the boom height should be
set to 25 to 27 inches off the ground.
After setting your boom height on the booms mounted on
the Tandem Axle Sprayers,there maybe a need to adjust
thefoldlatchwhen theboom is readyto be folded.Referto
Figure 11, page 17. If a hose fitting or nozzle ispositioned
where the fold latch is located, the fold latch needs to be
offset with the foldlatch extension provided. The foldlatch
extensioncan be mounted in the forward or rear direction;
in any direction the fold latch needs to be repositioned. After repositioning the fold latch, be sure to torque bolts to
the specifications listed in the Torque Values Chart for
Common Bolt Sizes in Appendix. If boom height is in the
lower ranges, you may want to raise the boom for transport. Refer to Elevator in the Sprayer Owner’s Manual.
Adjustments
19
Nozzle Pressure
Another area that will need some field adjustments is the
nozzle pressure. As your tank leveldecreases, you may
haveto adjust the boom pressure to keep the pressure at
the same magnitude for what the sprayer was calibrated
for. Watch your pressure gauge and be aware of changes
in the pressure.
Break-Awa y Pivot
The boom break-away pivot spring should be adjusted so
thatthe compressed length is53/8 of an inch.If the spring
is not compressed to 5 3/8", the boom will tend to break
awayover bumps and wear out the break-away mechanism. Refer to step 7 under Sprayer/Boom Assembly In-
structions on page 10, along with Figure 1 on page 11.

Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.
Equipment Cleanup
Nozzles should be cleaned with a low pressure (less than
30 psi) air hose, and periodically replaced. Haul a supply
tank of water so you can clean the spray tank and applicator out in the field. Never wash tank out in the yard or at a
car wash.
Dispose of left-over chemical in the same manner described on the manufacture’s label of the chemical last
usedinthe sprayer.Rinse out the tankandspray the rinse
water on the last field that was sprayed.
General Information
If equipment is to be used in freezing or near freezingconditions, protect pump and plumbing system by thoroughly
draining liquid and pumping antifreeze solution through
system to coat the interior of the pump and plumbing.
Before working on, servicing or making adjustments on
sprayer, always disengage power, shut off tractor engine,
makesureallmovingparts havestopped,and allpressure
in the system is relieved.
Checktheconditions ofhoses andconnections frequently.
Releasethe system pressure beforeworking on the sprayer.To release the pressure flip the boom section switches
on and off without the pump running. Alwayswear rubber
gloveswhen makingrepairs or adjustments.Make sure all
Protective Equipment (gloves,goggles, etc.) listed on
page 5, are stored in an easily accessible place but protected from potential contamination from dust or chemicals.
Check the sprayerfor any loose bolts, pins, and hose
clamps.
Checkthe hoses, pumps, valves,andfittingsfor any leaks.
Inspect all parts of the sprayer for wear and rust. Repair
and paint parts as necessary.
Storage
1. Empty solution from your sprayertank and store or
disposeof the chemical as recommended bythemanufacturer’s chemical label.
2. Change filters in the tractor cab after finished.
