from wind gusts and direct sunlight. Parkthe boom in
an area where children do not play. If possible, store
the boom inside for longer machine life.
3. Unfold the boom.
Refer to Figure 7
4. Position parking stands (1) under the center frame
and carrier. Make sure the parking stands are positioned over level, firm ground so the boom will be stable from front to rear. If the ground is soft, place
boards under parking stands to increase ground-contact area.
5. Lower the tractor hitch so the boom rests on the parking stands. Secure stands to boom with wire pins (2).
6. Unhook PTO pump or unplug hydraulic lines from hydraulic pump.
7. Unhook cam-lock connectors and hydraulic hoses
and position hoses on frame.
8. Remove three-point pins from tractor and pull away

Adjustments
Boom Height
After calibrating sprayer for the specific nozzle to be used
ata desired pressure, and tractor speed,the main field adjustment is boom height. Refer to Elevator Option in the
sprayerowner’smanual. Depending on which type of nozzle used, set boom height to achievecorrect overlap for
that specific 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
the height of the boom needed.
EXAMPLE: A 2.5 Metercone nozzle at 20 inch spacing is
being used. From the nozzle chart, a height of 19 to 21
inches above the top of the crop is required. If the crop is
6 inches off the ground, the boom height should be set to
25 to 27 inches off the ground.
Nozzle Pressure
Another area that will need some field adjustments is nozzle pressure. As tank level decreases, adjust the boom
pressure to keep the pressure at the same magnitude for
what the sprayer was calibrated for.Watch the pressure
gauge and be aware of changes in pressure.
Break-Awa y Spring
The break-away spring is located near the hinge for the
outside boom arm. On early models the break-away
spring should be compressed to a length of 5 3/8 inches.
On later models tighten the nuts that compress the spring
until all threads are bottomed out.
Fold Bracket
Thefoldbracketshold outside boomarmupwhen boom is
in the folded position. These bracketsare initially positionedat the factoryat an optimumposition so whenboom
is unfolded, the fold bracketswill not interfere with spray
pattern. The brackets need to be positioned so both portionsof thebracketare locatedthe same distancefrom the
adjacent nozzle. The bracket also needs to be positioned
so when boom is folded, the outer boom wing rests on the
fold rest, not on break-away nuts located near the hinge
point of outer boom wing. If the outer boom wing is resting
on the nuts, they will damage tubing on boom.
Spring Arm Tension
Refer to Figure 8
Leveling the Boom
For even application, the sprayer boom must be level
across the span. The boom is initially leveled during assembly. You may need to make additional adjustments to
levelthe boom. To level the boom, refer to Leveling the
Boom, Preparation and Setup, page 14.
Boom Fold
Ifboom is not foldingsquarely into the foldrest as itshould
due to damage on boom or some other reason, the boom
foldwill need to be adjusted. Fold boom wing to a position
just above the stop rest. Slightly loosen the four adjustment plate nuts until boom wing can move.Positionboom
wing to stop square in the rest stop and retighten adjustment plate nuts to 150 foot pounds. Make sure the
adjustmentplate isadjusted sothere arenogaps between
theball joints of hinge and hinge tubing onboomwing. Unfoldboom wing and re-torque adjustment plate nuts again.
Tighten the spring nut until spring is compressed to a
length of 10 inches. Lock with second nut.

Maintenance and Lubrication
Maintenance
Properservicingandmaintenance is the keyto longimplement life.With careful and systematic inspection, you can
avoid costly maintenance, downtime and repair.
Alwaysturn off and remove the tractor key before making
any adjustments or performing any maintenance.
!
Some chemicals can cause serious burns, lung damage, and
evendeath. Avoidcontact with skin or eyes.Wearproper protective equipment as required by chemical manufacturer. Avoid
prolonged breathing of chemical fumes. Wear respirator as required by chemical manufacturer. Seek medical assistance immediately if accident occurs. Know what to do.
Crushing hazard. Hydraulic failure or boom instability could
cause the boom to fall and result in serious injury or death. Secure boom to parking stands before performing any maintenance.
Crushing and pinching hazard. The boom has many pinch
points during folding. Bystanders could be injured by the moving sections. Hydraulic failure could cause the boom to fall on
bystanders. Keep all bystanders away during boom folding.
Fold the boom only when the tractor is parked.
DANGER
!
WARNING
!
WARNING
1. Clean nozzles with a low pressure (less than 30 psi)
air hose and replace periodically.
2. Release the system pressure by flipping the boom
sectionswitches on and off without thepump running.
3. Check hoses, pumps, valves, and fittings for leaks. Always wear rubber gloves when making repairs or adjustments.
4. Check sprayerfor loose bolts, pins and hose clamps.
Cables and Rollers
Inspect cables and rollers for proper rolling.
If a roller does not turn, inspect the roller for dirt or other
imperfections on the bearing surface.
The rollers have a self-lubricating bearing. Do not lubri-
cate bearings with oil. Lubricating the bearing may cause
dirt accumulation that jams the roller.
Keep cables tight with the spring compressed to 10 inches. See Spring Arm Tension,“Adjustments,” page 18.
Storage
Store the boom where children do not play. If possible,
store the boom inside for longer life.
1. Empty solution fromsprayertank and storeordispose
of chemical as recommended in the chemical manufacturer’s instructions.
2. Change filters in the tractor cab.
3. Washboom exteriorthoroughlyusing asafesolventor
soap and water.
!
WARNING
Escaping fluid under pressure can penetrate the skin causing
serious injury. Check all hydraulic lines and fittings before applyingpressure.Usepaper or cardboard,NOTBODYPARTS,to
check for suspected leaks. Wear protective gloves and safety
glasses or goggles when working with hydraulic systems. If an
accident occurs, see a doctor immediately. Any fluid injected
into the skin must be surgically removed within a few hours or
gangrene will result.
!
CAUTION
Before servicing or adjusting the sprayer or boom, always disengage power, shut off tractor engine, make sure all moving
parts have stopped, and relieve all system pressure.
