EAGLE BOOM

Description

The HARDI EAGLE boom is available in the

following sizes and models:

The 18-20 EAGLE booms are built with the same basic

components, with the 18 m having a different outer wing

section than the 20 m.

The 24-28 EAGLE booms are built with the same basic

components, with the 24 m having a different outer

section and different break-away section than the 28 m

(2.5 m on the 24 m boom and 2.8 m on the 28 m boom).

Components cannot be exchanged between 18-20

EAGLE and 24-28 EAGLE booms.

EAGLE booms are available in two different hydraulic

fold versions - XY and YZ. And one manual fold version

- XY.

XY (Manual Fold) model

Featuring hydraulic lift cylinder for boom height adjust-

ment and manual boom wing fold and unfold.

XY (Hydraulic Fold) model

Featuring hydraulic lift cylinder for boom height adjust-

ment and two-fold cylinders for simultaneous boom wing

fold and unfold.

YZ model

The same features as XY (Hydraulic Fold) model but

also has two boom wing tilt cylinders that give the ability

to obtain individual boom tilt as well as individual boom

wing fold.

Both hydraulic versions require one single acting hy-

draulic oulet and one double acting hydraulic outlet on

the tractor. The YZ model also requires a 12 volt con-

nection for the in-cab mounted controls.

All EAGLE booms can be equiped with either single

Snap-Fit or Triplet Snap-Fit nozzle bodies.

Connection

The EAGLE boom requires:

• 1 single acting hydraulic outlet (All models)

• 1 double acting hydraulic outlet (All except XY

(Manual Fold) models)

• 1 12 volt power supply (YZ models only)

Connecting hydraulics

1Attach the heavier (3/8”) hydraulic hose to the trac-

tor’s single acting outlet.

2Attach the smaller (1/4”) hydraulic hoses to the

tractor’s double acting outlet.

IMPORTANT! Ensure hydraulic lines have not

been damaged during shipping.

IMPORTANT! Be sure to hook up hydraulic lines

properly!

WARNING! Improper hook-up can cause danger-

ous boom movements and/or damage to the

sprayer hydraulics.

WARNING! Ensure all connections are tight before

applying pressure. Search for leaks with a piece of

cardboard - not your hands!

WARNING! Escaping hydraulic fluid under pres-

sure can penetrate the skin causing serious injury.

Avoid this hazard by relieving pressure before

disconnecting hydraulic lines.

WARNING! Always shut tractor off when connect-

ing, servicing or adjusting boom.

Connecting electric controls

1Attach the handle to the hydraulic lever that operates

the double acting outlet you intend to use. The

universal mounting bracket (E Fig 2) is very flexible

and a number of different mounting positions can be

used.

If required as an alternative to the handle, mount the

switch box in a suitable location in the tractor cab.

2Connect the handle power plug or switch box power

plug (F Fig 2) to the tractors 12 volt power system.

Try to connect the handle or switch box as close as

possible to the battery for a better power supply.

HARDI recommends using electric distribution box

#817925 to insure a good power supply to various 12

volt attachments.

NOTE! Check with your HARDI dealer or your

tractor’s operator’s manual for the best location to

hook up the 12 volt system.

Operation

CAUTION! Always operate boom on level

ground.

WARNING! Do not allow anyone near a hydraulic

boom in operation.

WARNING! Be cautious with initial use of the

hydraulic systems. If there is air in the system, this

may cause violent movements of the boom.

Therefore take care that no persons are hurt or

objects are damaged in the process of testing.

DANGER! When folding and unfolding the boom,

be sure that no person or objects are in the operat-

ing area of the boom, and that the boom cannot

touch overhead electrical wires.

Release from transport supports

1Start tractor and bring engine to operating rpm.

2Activate the single acting outlet to lift the boom out of

the transport supports.

NOTE! The boom has a rear transport hook in the

centre of the gantry. This hook has to be released

by lifting the boom with the single acting outlet until

the control arm of the hook appears between the

two flat bars of the hook guide (Fig 4).

Be careful not to bring the control arm past the

opening on the hook guide.

Fig 4

Boom folding and unfolding (XY (Manual Fold)

model)

1Raise the boom to release it from transport supports.

2Manually unfold each wing separately until the

mechanical lock on the wing is engaged

3When the boom is completely unfolded, it can be

raised or lowered to desired spray height by activat-

ing the single acting hydraulic outlet.

4Before attempting to fold boom wings back into the

transport position, the boom should be raised all the

way to the top by activating the single acting outlet.

5Pull the cable to release the mechanical lock on the

wing, fold the wing by pushing it toward the boom

rest (assisted by a spring). Leave the folded wing

suspended above the boom rest and repeat the

process for the other wing.

Boom folding and unfolding (XY (Hydraulic

Fold) model)

1Raise the boom to release it from the transport

supports.

2Activate the double acting hydraulics outlet to unfold

the boom. Both wings will now unfold simultaneously.

3When the boom is completely unfolded, it can be

raised or lowered to the desired spray height by

activating the single acting hydraulic outlet.

4Before attempting to fold the boom wings back into

the transport position, the boom should be raised all

the way to the top by activating the single acting

outlet.

NOTE! This time the control arm on the hook

should be raised past the opening of the hook

guide (Fig 5).

Fig 5

When the boom has been raised high enough for the

control arm to go past the opening on the hook

guide, wings can be folded into transport position.

5The boom is folded in by activating the double acting

outlet. The boom can now be lowered into the

transport supports. Ensure that the hook engages on

the crossbar on the gantry (rear transport).

Boom folding and unfolding (YZ model)

1Raise the boom to release it from the transport

supports.

2Depress the fold switches (A Fig 2) and (B Fig 2)

and move the hydraulic handle forward or rearward

to activate oil flow. If you do not like the direction

required to activate the boom, switch the positions of

the hoses in the double acting outlet.

3One side folding can be acheived by following the

above procedure, except that only one of the

switches is depressed.

Boom tilting (YZ model)

1Depress the fold switch (C Fig 2) or (D Fig 2) de-

pending on what side needs to be tilted, and move

the hydraulic handle to activate oil flow.

Maintenance

In order to derive full benefit from the boom

for many years, the following maintenance

program should be followed.

IMPORTANT! Always read carefully through the

individual paragraphs regarding maintenance jobs

before starting the job. If any portion remains

unclear or requires facilities which are not avail-

able, then for safety reasons please leave the job

to your HARDI dealer’s workshop.For maintenance

of the sprayer, please refer to your sprayer’s

operator’s manual

To effectively maintain the boom you must:

1 Clean the boom as part of cleaning the sprayer, after

spraying is completed and before performing any

maintenance - Refer to

Cleaning

2 Lubricate the boom according to the lubrication

interval reached - Refer to

Lubrication

3Perform Adjustments as needed following a daily

boom inspection - Refer to

Adjustments

(Page 9).

4Perform Occasional maintenance jobs as needed

following boom inspections - Refer to

Occasional

maintenence

(Page 13).

5Immediately fit Replacement parts for parts that are

worn or broken - Refer

Replacement Parts

(P.17).

Cleaning

The entire sprayer and the boom should be cleaned

together only (Refer to the

Cleaning

section in your

HARDI sprayer’s operator’s manual).

If you have a HARDI EAGLE boom fitted to an older

HARDI sprayer that does not have an operator’s

manual, or if you have a HARDI EAGLE boom fitted to a

non HARDI sprayer and you don’t have any form of

instructions or manuals, please read below for a brief

overview of cleaning:

NOTE! FOLLOW GUIDELINES ON CHEMICAL LABELS FOR

DILUTION AND CLEANING PROCEDURES AT ALL TIMES.

1Dilute the remaining spray liquid in the tank with

least

10 parts of water and spray the liquid out into

the field you have just sprayed.

2Select and use the appropriate protective clothing.

Select detergent suitable for cleaning and suitable

deactivating agents if necessary.

3Flush and clean the sprayer and tractor externally.

Use detergent if necessary.

4Remove all the filters and clean them - be careful not

to damage their mesh. Re-fit the filters when the

sprayer is completely clean.

5Clean the pressure relief valve and attached hose of

any residue.

6With the pump running, flush inside of the main tank

(remember the tank roof). Flush and operate all

components and any equipment that has been in

contact with the chemical. Before opening the

distribution valves and spraying the liquid out,

identify a suitable disposal method for the solution.

7After spraying the liquid out, stop the pump and fill at

least 20% of main tank with clean water. Note that

some chemicals require the tank to be completely

filled. Add appropriate detergent and/or deactivating

agent, e.g. Washing Soda or Triple Ammonia.

8 Start the pump and operate all controls, enabling the

liquid to come in contact with all the components.

Remove end plugs on boom tubes while pump is not

running, then flush with clean water to ensure thor-

ough removal of residue. Leave the distribution

valves until last. Some detergents and deactivating

agents work best if left in the tank for a short period.

Check the label.

9Drain the tank and if the pump is able to - let the

pump run dry. Flush the inside of the tank, again

letting pump run dry (if possible).

10 If the chemicals used have a tendency to block

nozzles and filters, remove and clean them now.

11 Re-fit all the filters and nozzles and store the

sprayer. If from previous experiences, it is noted that

the solvents in the chemicals are particularly aggres-

sive, store the sprayer with the tank lid open.

Lubrication

Recommended lubrication intervals and lubricants are

as follows.

8 Hours

Gantry and centre frame

Apply new grease to the wear surfaces of the gantry

and the centre frame (Fig 6).

1Apply grease to the inner and outer wear surfaces of

the lower portion of the gantry with the boom hanging

for applying the new grease.

Adjustments

IMPORTANT! To maximise boom life and perform-

ance, re-tighten all boom fasteners and inspect the

boom for proper adjustment after the first 8 hours

of use.

IMPORTANT! Make it a daily (8 hours) habit to

inspect the boom for need of adjustment.

IMPORTANT! Every 40 hours, the break-away

clutch cap screws (A Fig 14) must be torqued to 55

Nm to prevent boom damage.

Checking and adjusting sprocket timing

1With boom unfolded in the spraying position and

standing on the front side of the boom, check to

ensure that on the 18-20 boom, the 7th pin connec-

tion (A Fig 9) in the timing chain, is aligned with the

centre line between the sprocket cap screws (B Fig

9). For the 24-28 boom - 6th pin.

2To adjust timing, loosen turnbuckles on the front and

rear cables until slack.

318-20 boom: Standing on the front side of the

boom, position the 7th pin (A Fig 9) of the timing

chain on the sprocket as indicated in step 1.

24-28 boom: Standing on the front side of the

boom, position the 6th pin (A Fig 9) of the timing

chain on the sprocket as indicated in step 1.

horizontal position, the bolts must be loosened again.

Fig 18

Adjusting boomtransport position

Manual fold boom

1Fold the boom into the transport position. Determine

if the boom sections need to be adjusted inwards or

outwards.

2The manual fold “cylinder” has an inner and an outer

section. The inner section has a turnbuckle on both

ends. One turnbuckle is quite obvious and can be

adjusted by loosening the nut, while the other

turnbuckle protrudes through the inside of the outer

section - to adjust it, the inner and outer sections

must be pulled apart, the turnbuckle turned and

reassembled.

NOTE! If under adjusted, the boom may sit too

close to the boom rest guards. If over adjusted, the

boom may be unable to be locked in the open

position.

Hydraulic fold boom

1Lift the boom all the way to the top.

2Fold the boom into the transport position. With the

fold cylinder pressurized, determine if the boom

sections need to be adjusted inwards or outwards.

NOTE! The boom should be approximately 2-5 cm

inside front transport support.

EAGLE BOOM

3If the boom rests too far in on the transport support,

loosen the lock nut (B Fig 19) and adjust the collar

(A Fig 19) in towards the cylinder housing.

4If the boom rests too far out on the transport support,

the collar (A Fig 19) has to go out from the cylinder

housing.

5Secure the lock nut (B Fig 19).

6Pressurise the cylinder to see if the boom is properly

adjusted. If not, repeat the above procedure until it is

correctly adjusted.

Fig 19

Adjusting rear cable

WARNING! Rear cable can snap and injure you or

someone else if tensioned when the boom is

unfolded. Always adjust the front cable first with

the boom unfolded and the rear cable last with the

boom folded in the transport position.

1Raise the boom to its highest position. Fold the

boom to the transport position with the tilt cylinders (if

fitted) fully extended. Make sure fold cylinders are

pressurised and that the boom is folded all the way

in.

NOTE! If you have a YZ model, shut the fold

switch off.

2Shut the tractor off.

3Loosen the lock nuts on the turnbuckle. Adjust

(tighten) the turnbuckle so that the outer wing section

contacts the boom transport stop bracket. Tighten

the turnbuckle another 4 complete turns (24-28 boom

- tighten the turnbuckle 3 turns only) and re-tighten

the lock nuts.

Adjusting centre frame cables

IMPORTANT! Never attempt to adjust the centre

frame cables without having the boom folded all

the way into the transport position!

Centre frame cables work together to keep the centre

frame square to the gantry, while folding boom in for

transport or when spraying with one side raised and

folded.

1Fold the boom into the transport position.

2Shut the tractor off.

3Check that the tilt cylinders (if fitted) are completely

retracted. Adjust if necessary.

4Loosen the lock nuts.

IMPORTANT! Alternate from side-to-side while

making adjustments. Adjust one cable a small

amount, and then the other - to equalize cable

tension and maintain a level centre frame.

5Properly adjusted cables will be very tight and only

deflect a small amount (fractions of a centimetre)

when pulled on by hand.

6Tighten the lock nuts.

7Unfold the boom to operating (spraying) position.

8Fold the boom and check that the centre frame

remains square to gantry.

Occasional maintenance

Make it a regular habit to inspect the boom for need of

occasional maintenance.

Nozzle filters

Each nozzle assembly is equipped with a 100 mesh

filter screen as standard on units equipped with yellow

Color Tips. A properly maintained suction filter and self

cleaning Filter will eliminate blocking the screens and

nozzles.

Tubes and fittings

Poor seals are usually caused by:

• Missing O-rings or gaskets

• Damaged or incorrectly seated O-rings

• Dry or deformed O-rings or gaskets

• Foreign materials

Therefore, in case of leaks, do not over-tighten. Disas-

semble, check condition and position of O-ring or

gasket, clean, lubricate and reassemble.

For radial connections, only hand tighten them.

The O-rings need to be lubricated all the way around

before fitting on to the nozzle tube.

HARDI recommends using a vegetable

based oil to prolong the life of the O-ring.

Storage/Transportation

Safe transport and towing

Keep all persons away from the sprayer when

folding the boom.

Transport booms only when booms folded and resting in

transport support arms.

Ensure the transport hook on the gantry is engaged

properly.

Maximum transport speed is the lesser of:

20 km/h less than the posted speed limit; and

30 km/h; and

The tyre manufacturers maximum speed.

Have warning lights flashing when transporting or towing

a sprayer.

DANGER! Keep away from overhead powerlines

to avoid serious injury or death to yourself or

someone else. Know the transport height of the

sprayer, and minimum clearances (see p 2).

Off season storage

When the spraying season is over, you should devote

some extra time to cleaning and preparing the sprayer

for storage.

Please refer to the

Storage

section in your HARDI

sprayer’s operator’s manual regarding preparation

before and after off season storage.

If you have a HARDI EAGLE boom fitted to an older

HARDI sprayer that does not have an operator’s

manual, or if you have a HARDI EAGLE boom fitted to a

non HARDI sprayer and you don’t have any form of

instructions or manuals, please read below for a brief

overview of storage preparation:

To preserve the sprayer and protect the components,

carry out the following off season storage program.

1Clean the sprayer completely - inside and outside.

Make sure that all valves, hoses and auxiliary equip-

ment have been cleaned with detergent and flushed

with clean water, so no chemical residues are left in

the sprayer.

2Renew damaged seals and repair leaks.

3Empty the sprayer completely and let the pump work

for a few minutes. Operate all valves and handles to

drain as much water off the spraying circuit as

possible. Let the pump run until air is coming out of

all the nozzles (If possible). Remember to drain the

flushing tank. Ensure the foam marker is rinsed and

drained.

4If the sprayer is not to be stored in a frost free place,

pour in a mixture of Ethylene Glycol based anti-

freeze and water at the ratio for the desired tempera-

ture protection. Volume of mixture should be about

1% of tank volume. Run the sprayer and circulate the

anti-freeze in the pump, controls and boom lines.

Fig 20

Triplets (If fitted)

Every 50 hours the Triplets should be disassembled,

removed and cleaned. This is done by pulling out the

stainless clip on the side of the Triplets assembly (Fig

21).

Clean the bottom part as well as the top part thoroughly.

Coat the O-ring with a light film of vegetable oil or “O-

ring Grease” if the sprayer is to be stored for a long

period of time.

If the Triplets are not cleaned regularly, possible dam-

age to them may occur.

WARNING! Never service your contaminated

nozzle without wearing chemical resistant gloves

and safety goggles.

EAGLE BOOM

Troubleshooting

In cases where breakdowns have occurred,

the same factors always seem responsible.

Usually hydraulic components that are contaminated

with dirt result in rapid wear to the hydraulic system.

Therefore always check hydraulic components are

maintained, clean and free from leaks.

5Lubricate all lubricating points regardless of intervals

stated.

6When the sprayer is dry remove rust from scratches

or damages and touch up with paint.

7Remove any Glycerine filled gauges and store them

in a frost free vertical position.

8Apply a thin layer of anti-corrosion oil to all metal

parts, hoses and tyres. There are many factors that

affect the selection of protective oils, such as tem-

perature and humidity during storage, exposure to

UV, salt and the effects of residual crop treatment

chemicals, and your local distributor of oil products

will be able to advise on the best specific formula for

your local conditions. Products that may be suitable

to protect your equipment until the next spraying

season are SHELL ENSIS fluid, or one of the

CASTROL RUSTILLO range of products, eg

DW9011M1.

9Fold the boom to the transport position and relieve

pressure from all hydraulic functions.

10 All electric plugs and sockets are to be stored in a

dry plastic bag to protect them against damp, dirt and

corrosion.

11 Remove any control boxes (if fitted) from the tractor

and store them inside where it is clean and dry.

12 Wipe the hydraulic snap-couplers clean and fit the

dust caps.

13 Apply grease on all hydraulic ram piston rods that

are not fully retracted in the barrel, to protect against

corrosion.

14 Chock up the wheels, to prevent moisture damage

and deformation of the tyres. Tyre blacking can be

applied to the tyre walls to preserve the rubber.

15 To protect against dust the sprayer can be covered

by a tarpaulin. Ensure ventilation to prevent conden-

sation.

After a storage period the sprayer should be prepared

for the next season the following way:

1Remove the cover.

2Remove the support from the wheel axle and adjust

the tyre pressure.

3Wipe off the grease from hydraulic ram piston rods.

4Fit any pressure gauges again (seal with teflon tape).

5Connect the sprayer to the tractor including hydrau-

lics and electrics.

6Check all hydraulic and electric functions.

7Empty the remaining anti-freeze from the tank (If

used).

8 Rinse the entire liquid circuit of the sprayer with

clean water.

9Fill with clean water and check all functions.

Replacement Parts

This section is to be used to help you identify

the replacement part numbers of many

common parts on the EAGLE boom - it is not as com-

prehensive as the

Spare Parts

manual at your HARDI

dealer.

So if a part is not covered in this section, or is difficult to

determine, you will need to contact your HARDI dealer.

Every part illustrated in this section has a number or is

shown as part of a group of parts in a numbered kit.

This number is the HARDI parts number for the part or

kit of parts.

Note that drawing numbers used in this section do not

represent any HARDI parts drawing numbers - they are

simply used for cross-referencing within this manual.
