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.
