serious injury. This signal word is limited to the
most extreme situations, typically for machine
components that, for functional purposes, cannot
be guarded.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury, and includes hazards that are exposed when guards are removed. It may also be
used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.

9. Start sprayer pressurizing system to work up
to desired pressure.
10. When applying chemicals in the field, your
goals are accuracy, efficiency and safety. To
reduce expenses and risks to human health:
• Apply spray when wind is 5 mph or less.
• Take note of adjoining crops, houses or
persons.
• Minimize drift by using nozzle tips with the
largest practical opening and by operating
boom at the lowest practical height.
• Work crosswise to the wind. Start from the
down-wind side of the field to avoid heading
directly into chemical fumes.
• When turning at the end of field, make sure
boom will not overlap previously sprayed
crop.
• While spraying, monitor pressure closely.
Maintain a constant tank pressure for even
and accurate spraying.
• Periodically check hoses, connections and
nozzles. Release pressure before working
on sprayer or boom. Always wear rubber
gloves when making repairs or adjustments.
11. When finished spraying, empty tank and flush
sprayer with water, including the pump, nozzles and valve-bypass line. Store or dispose
unused chemicals as recommended by the

parking instructions. For information on long-term
storage, refer to “Storage,” page 29.
Refer to Figure 6
To park a three-point boom, follow these steps:
1. Flush sprayer with water in last field sprayed.
Flush pump, nozzles and bypass line from
valves.Store or dispose unused chemicalsas
recommended by the chemical manufacturer.
2. Park boom on a level, flat area that is protected from wind gusts and direct sunlight. Park
boom in an area where children do not play. If
possible, store boom inside for longer machine life.
3. Unfold boom.
4. Position parking stands under three-point
mount and center section of boom frame.
Make sure parking stands are positioned over
level, firm ground so boom will be stable from
front to rear. If the groundis soft, place boards
under parking stands to increase ground-contact area.

WARNING!
Crushing hazard. The boom could fall and cause serious injury or death. Before performing any maintenance, secure boom to parking stands if provided.
Hydraulic Elevator
Refer to Figure 7
Periodically check the slide pads (A) for wear. As
the pads wear, tighten 1/2-inch bolts (B) on both
sides of elevator frame (C) until pads just touch
frame.
Adjustments
23
Boom Height
After calibrating sprayer for your nozzles, desired
pressure and tractor speed, the main field adjustment is boom height. Set boom height to achieve
correct overlap for your nozzle. If the crop canopy
is taller in some fields than others, adjust boom
height accordingly.
Refer to nozzle tables in the Application Guide to
determine correct boom height.
Leveling Boom
For even application, the sprayer boom must be
level across the span. The boom is initially leveled
during assembly. After a period of normal use, you
may need to level the boom.
If necessary, refer to “Leveling Boom,” page 17.

Wing Folding
Refer to Figure 12
Normal boom use may cause wing misalignment.
If the inner- and outer-arm sections are out of
alignment, the outer arm (A) will miss the fold
bracket (B) on the inner arm when boom is folded.
To realign wing sections, loosen 1/2-inch bolts at
arm joint. Swing outer-arm section until it is
aligned with inner-arm section. Retighten bolts.
Normal boom use may also shift the folding brackets along the inner-arm section. When properly
adjusted, the outer arm will meet the fold bracket
at the stop (C). Loosen u-bolts and reposition
brackets as necessary.

Troubleshooting
Problem Solution
Excessive cable wear
Pressure increases
Optional electric-hydraulic control not
working
Restricted oil flow to optional electrichydraulic control
No oil flow and no clicking sound
from valve on optional electrichydraulic control
Check cable and roller for obstruction or wear. Remove obstructions.
Check that roller is turning properly. Replace roller or roller bushing if
necessary.
If necessary, replace worn cable.
Check for clogging in boom hoses. Remove obstruction.
Check if boom hoses are pinched. Use cable ties to keep hoses from
kinking.
If valve does not work and indicator lights are not lit, check for a blown
fuse, damaged wiring or a bad switch.
If valve does not work but indicator lights are lit, check that system is
properly grounded. Ground valve by running a wire from the tractor
frame to the coil nut on top of the valve.
Do not mix and match styles of tips and couplers.
Check that hydraulic hoses are not blocked, damaged or kinked.
Check valve cartridge for internal contamination. Before removing cartridge, relieve all hydraulic pressure and remove all hydraulic hoses
from ports. Contact your Great Plains dealer for cartridge-cleaning
instructions.

30 psi. Periodically replace nozzles.
3. Check hoses, pumps, valves and fittings for
leaks. Always wear rubber gloves when making repairs or adjustments.
4. Check sprayer for loose bolts, pins and hose
clamps.
Cables and Rollers
Refer to Figure 13
Inspect cables and rollers for proper rolling. If a
roller does not turn, inspect roller for dirt or other
imperfections on bearing surface.
Rollers have a self-lubricating bearing. Do not lubricate bearings with oil. Lubricating bearing with
oil may cause dirt accumulation that jams roller.
Keep cables tight and spring compressed to
10 1/4 inches. See “Spring Arm Tension,” page
25.
Optional Hydraulic Elevator
Keep slide pads properly adjusted as explained
under “Hydraulic Elevator,” page 23. Do not
grease slide pads. Lubricating slide pads with
grease may cause dirt accumulation that jams elevator. If necessary, use silicone spray on slide
pads.
