EAGLE BOOM
Introduction
The reliability and efficiency of the HARDI EAGLE boom depends upon your care. The
first step is to take the time to carefully read this operator’s manual. It contains essential information on efficient and safe operation of the HARDI EAGLE boom.
Thankyou for choosing HARDI and welcome to the increasing family of HARDI spraying equipment owners.
Boom use
The HARDI EAGLE boom is for use on a HARDI sprayer - for the application of plant protection and liquid fertiliser chemicals. The sprayer fitted with the EAGLE boom must only be used for this purpose. It is not allowable to use the sprayer for other purposes. If no local law demands that the operator must be certified to use spray equipment, it is strongly recommended to be trained in the safe handling of plant protection chemicals and plant protection, to avoid unnecessary risk for persons and the environment.

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 adjust­ment and manual boom wing fold and unfold.
XY (Hydraulic Fold) model
Featuring hydraulic lift cylinder for boom height adjust­ment 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 hy­draulic oulet and one double acting hydraulic outlet on the tractor. The YZ model also requires a 12 volt con­nection for the in-cab mounted controls.
All EAGLE booms can be equiped with either single Snap-Fit or Triplet Snap-Fit nozzle bodies.

EAGLE BOOM
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
1 Attach the heavier (3/8”) hydraulic hose to the trac-
tor’s single acting outlet.
2 Attach 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 danger­ous 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 pres­sure can penetrate the skin causing serious injury. Avoid this hazard by relieving pressure before disconnecting hydraulic lines.
WARNING! Always shut tractor off when connect­ing, servicing or adjusting boom.
Connecting electric controls
1 Attach 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.
2 Connect 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 operat­ing area of the boom, and that the boom cannot touch overhead electrical wires.
Fig 3
Release from transport supports
1 Start tractor and bring engine to operating rpm. 2 Activate 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)
1 Raise the boom to release it from transport supports. 2 Manually unfold each wing separately until the
mechanical lock on the wing is engaged
3 When the boom is completely unfolded, it can be
raised or lowered to desired spray height by activat­ing the single acting hydraulic outlet.
4 Before 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.
5 Pull 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)
1 Raise the boom to release it from the transport
supports.
2 Activate the double acting hydraulics outlet to unfold
the boom. Both wings will now unfold simultaneously.
3 When the boom is completely unfolded, it can be
raised or lowered to the desired spray height by activating the single acting hydraulic outlet.
4 Before 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.
5 The 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)
1 Raise the boom to release it from the transport
supports.
2 Depress 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.
3 One side folding can be acheived by following the
above procedure, except that only one of the switches is depressed.
Boom tilting (YZ model)
1 Depress 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 avail­able, 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
.
3 Perform Adjustments as needed following a daily
boom inspection - Refer to
Adjustments
(Page 9).
4 Perform Occasional maintenance jobs as needed
following boom inspections - Refer to
Occasional
maintenence
(Page 13).
5 Immediately 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.
1 Dilute the remaining spray liquid in the tank with
at
least
10 parts of water and spray the liquid out into
the field you have just sprayed.
2 Select and use the appropriate protective clothing.
Select detergent suitable for cleaning and suitable deactivating agents if necessary.
3 Flush and clean the sprayer and tractor externally.
Use detergent if necessary.
4 Remove all the filters and clean them - be careful not
to damage their mesh. Re-fit the filters when the sprayer is completely clean.
5 Clean the pressure relief valve and attached hose of
any residue.
6 With 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.
7 After 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 thor­ough 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.
9 Drain 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 aggres­sive, 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).
1 Apply grease to the inner and outer wear surfaces of
the lower portion of the gantry with the boom hanging in the transport hook.
2 Apply grease to the inner and outer wear surfaces of
the upper portion of the gantry with the boom un­folded and lowered all the way down.

Gantry and centre frame
The grease on the gantry and centre frame should be completely cleaned off with a degreasing solvent and new grease applied. Follow the
8 Hours
steps for
Gantry
and centre frame
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
1 With 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 connec­tion (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.
2 To adjust timing, loosen turnbuckles on the front and
rear cables until slack.
3 18-20 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.

7 Grasp the wing by the end and lift it approximately 50
cm. Let the wing go and it should go down to ap­proximately horizontal position.
8 Repeat the above process until the boom is firmly
held in place, but without affecting the trapeze function.
9 If the trapeze will not let the boom go back to the
horizontal position, the bolts must be loosened again.
Fig 18
Adjusting boomtransport position
Manual fold boom 1 Fold the boom into the transport position. Determine
if the boom sections need to be adjusted inwards or outwards.
2 The 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 1 Lift the boom all the way to the top. 2 Fold 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.

3 If 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.
4 If the boom rests too far out on the transport support,
the collar (A Fig 19) has to go out from the cylinder housing.
5 Secure the lock nut (B Fig 19). 6 Pressurise 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.
1 Raise 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.
2 Shut the tractor off. 3 Loosen 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.
1 Fold the boom into the transport position. 2 Shut the tractor off. 3 Check that the tilt cylinders (if fitted) are completely
retracted. Adjust if necessary.
4 Loosen 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.
5 Properly adjusted cables will be very tight and only
deflect a small amount (fractions of a centimetre) when pulled on by hand.
6 Tighten the lock nuts.
7 Unfold the boom to operating (spraying) position.
8 Fold 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.

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.
1 Clean the sprayer completely - inside and outside.
Make sure that all valves, hoses and auxiliary equip­ment have been cleaned with detergent and flushed with clean water, so no chemical residues are left in the sprayer.
2 Renew damaged seals and repair leaks. 3 Empty 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.
4 If the sprayer is not to be stored in a frost free place,
pour in a mixture of Ethylene Glycol based anti­freeze and water at the ratio for the desired tempera­ture 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 dam­age to them may occur.
WARNING! Never service your contaminated nozzle without wearing chemical resistant gloves and safety goggles.

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.
5 Lubricate all lubricating points regardless of intervals
stated.
6 When the sprayer is dry remove rust from scratches
or damages and touch up with paint.
7 Remove any Glycerine filled gauges and store them
in a frost free vertical position.
8 Apply 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 tem­perature 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.
9 Fold 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 conden­sation.
After a storage period the sprayer should be prepared for the next season the following way:
1 Remove the cover. 2 Remove the support from the wheel axle and adjust
the tyre pressure.
3 Wipe off the grease from hydraulic ram piston rods. 4 Fit any pressure gauges again (seal with teflon tape). 5 Connect the sprayer to the tractor including hydrau-
lics and electrics.
6 Check all hydraulic and electric functions. 7 Empty the remaining anti-freeze from the tank (If
used).
8 Rinse the entire liquid circuit of the sprayer with
clean water.
9 Fill 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 com­prehensive 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.
