We congratulate you for choosing a HARDI
plant protection product. The reliability and
efficiency of this product depend on your care.
The first step is to carefully read and pay
attention to this instruction book. It contains essential
information for the efficient use and long life of this
quality product.
As the instruction book covers all DEMOUNT models
with hydraulic LHZ and OLH booms, please pay atten-
tion to the paragraphs dealing with precisely your
model. This book is to be read in conjunction with the
“Spray Technique” book.
Description
The HARDI DEMOUNT model was designed
especially for all JCB FASTRAC models. It
consists of a short, compact frame, which is fixed to your
tractor, as well as a second frame with a 2000 litre polyes-
ter tank, pump, EC operating unit, self-cleaning filter,
support legs, and a hydraulic boom (DAH) of 12 to 24
metres. Additional equipment of the DEMOUNT model is
HARDI MANIFOLD SYSTEM, HARDI FILLER of 35 l, and
a rinsing tank of 200 l fitted on the three-point linkage at
the front.
The frame has a strong chemical and weather-resistant
lacquer. Screws, nuts, etc. have been DELTA MAGNI
treated and are therefore corrosion resistant.
The tank, made of chemical resistant polyester, has a pur-
poseful design with no sharp corners for easy cleaning.
The design of the hydraulic pump, with 6 diaphragms,
type 361 or 462, depending on boom width, is with
easily accessible diaphragms and valves that ensures
liquid does not contact the vital parts of the pump.
The EC operating unit is constructed of modules and
consists of main ON/OFF valve, pressure gauge, pres-
sure regulation with built-in HARDI-MATIC and distribu-
tion valves with pressure equalization. HARDI-MATIC
ensures a constant volume per hectare of the liquid
(l/ha) at varying speed in the same gear when the num-
ber of P.T.O. revolutions are between 300-600 r/min.
With the self-cleaning filter the impurities that exist in the
spray liquid will by-pass the filter and be recirculated
back to the tank via the return flow.
The hydraulic system consists of a hydraulic pump with
gear connected directly to the transmission shaft of your
tracker and a hydraulic motor fitted on and operating
the diaphragm pump. Further a double acting hydraulic
outlet is needed to operate the spray boom.
The fully electrical/hydraulic spray boom is equipped
with individual slanting control. LHZ booms of 12-16 m
are mounted on the frame by trapeze suspension, OLH
booms of 18-24 m by pendulum suspension. All booms
are equipped with HARDI COLOR TIPS and TRIPLET
SNAP-FIT.
Identification plates
An identification plate fitted on the frame and pump is to
indicate model, serial number and country of origin. Boom
centre frame, and inner/outer sections also have identifi-
cation plates indicating boom type and part no. of steel
parts. If ordering spare parts,
inform your dealer of these so
the right model and version
are described.
Sprayer use.
The DEMOUNT sprayer is for the application of crop
protection chemicals and liquid fertilzers. The equip-
ment must only be used for this purpose. It is not al-
lowed to use the sprayer for other purposes. If no local
law demands that the operator must be certified to use
spray equipment, it is a very good idea to be trained in
correct plant protection and in safe handling of plant
protection chemicals to avoid unnecessary risk for
persons and the environment when doing your spray
work.
Unloading the sprayer from the truck.
For the unloading of the sprayer you need a crane or a
fork lift. When loading with a crane please observe the
lifting points as shown on the sketch, and make sure
that the straps or belts used for lifting are strong
enough. When unloading with a fork lift,
please note from the drawing from which
side the sprayer should be lifted. If neces-
sary tie the sprayer to the gantry of the
fork lift to prohibit it from tilting.

Connecting the sprayer
Attachment of the mounting frame
The mounting frame is fixed to the tractor with
4 screws in front and 2 screws behind. Remember to
tigthen up the screws.
Connecting of the sprayer on the mounting frame
1. Raise the lift arms of the tractor to the upper position
as this facilitates the mounting. Jack up the sprayer
in small steps on the four sup-
port legs until there is at least
15 cm free space between
the tank and the mounting
frame so that the tractor
can drive under the
sprayer.
2. Drive the tractor under the sprayer
until the mounting frame is right
below the tank frame so that both of
the front brackets slot together.
3. Now lower the sprayer with the jacks on until the tank
frame is resting well on the mounting frame. Then lift up
the jacks several times in small steps.
4. When the sprayer is placed correctly on the mount-
ing frame, fit the two front pins and the single rear pin
to the brackets and secure with clevis pins.
5. Now pull out the pins from the front support legs and
remove the first part of these legs. Then pull out the
pins on the front of the mounting frame and remove
the second part of the support legs. As to the rear
support legs you pull out the pins at the gantry and
remove the support legs.
Demounting of the sprayer
The demounting takes place in the opposite direction.
However, always make sure that there is enough space
between the sprayer and the basic frame to remove the
tractor without damaging the bottom of the tank.
NOTE! The sprayer must be demounted and
placed on level and hard surface.
IMPORTANT! The sprayer must only be demount-
ed and placed on the jacks with empty tank!
Mounting of the front rinsing tank and hoses
Mount the rinsing tank on the tractor front three-point
linkage.
Then fix the hose support on the bracket of the front
axle spring suspension on the left side and place the
hose. Fix the support in such a way that the longer part
is pointed backwards.
Fasten the hose with the clamps to the protection rack
of the left and right side of the cabin ladder.
Then place the hose within the rear wheel in the three
clamps of the tank frame and connect it to the yellow
symbol of the rinsing tank of the MANIFOLD SYSTEM.
Mounting of the HARDI FILLER chemical
filling device.
The chemical filling device is
fitted at the FASTTRAC RH step with brackets as shown.

Demount
Hydraulic system
The D.A.H. system requires a double acting hydraulic
outlet. The hydraulic hoses are marked with arrows to
indicate direction of oil flow.
The D.A.H. system requires an oil flow between 10 to
90 l/min and a min. pressure of 130 bar. The system
has a built-in flow regulator that maintains constant
speed on hydraulic movements.
Before operating the hydraulics, the clip at the distribu-
tion valve (situated under the platform behind the pump)
should be set for OPEN CENTRE tractor hydraulics.
Hydraulic pump transmission
Before initial start fill the hydraulic oil tank with the 70 l
of hydraulic oil, type “SHELL TELLUS T46”, enclosed in
containers.
Connecting the hydraulic pump
Connect the hydraulic pump with the P.T.O. shaft of the
tractor. Make sure that the pump “locks” correctly. Fix
the pump in such a way that the profile fitted on the
right side is located on the right side of the coupling
device preventing the pump from rotation.
The hydraulic pump gear has already been filled with 0.7
l (25 imp.fl.oz) oil. However, check level before initial
start and never omit the regular service intervals.
Oil cooler (if fitted)
If the sprayer is operating in ambient temperatures
above 30°C (112°F) an oil cooler kit must be fitted in
order to keep transmission oil temperature at the speci-
fied level. The thermostat will engage the electric fan
when the oil temperature reaches appr. 50°C (148°F)
and disengage at appr. 40°C (130°F).
Connect the fan electric plug to a 12 V socket.
Control boxes and power supply
Two power boxes of 12V are required. Note polarity!
For EC: Brown pos. (+), blue neg. (-)
For D.A.H.: White pos. (+), black neg. (-).
The control boxes for EC-operating unit
and for D.A.H. are fitted in the tractor
cabin at a convenient
place. See section on
assembly for initial
mounting.
The wires must have a
cross-sectional area of
at least 4.0 mm to
ensure sufficient power
supply. For the EC-
operating unit the tractor
circuit should have an 8
Amp fuse and for the
D.A.H. a 16 Amp fuse.
Roadworthyness
When driving on public roads and other areas
where the highway code applies, or areas
where there are special rules and regulations for mark-
ing and lights on implements, you should observe these
and equip implements accordingly.
Before taking the sprayer into operation
Although the sprayer has been applied with a strong
and protective surface treatment on steel parts, bolts
etc. in the factories it is recommended to apply a film of
anti-corrosion oil (e.g. CASTROL RUSTILLO or SHELL
ENSIS FLUID) on all metal parts in order to avoid
chemicals and fertillizers to discolorate the enamel.
If this is done already before the sprayer is put into
operation the first time, it will always be easy to clean
the sprayer and keep the enamel shiny for many years.
This treatment should be carried out every time the oil
film is washed off.
Operating instructions
Filling of water
Water can be filled into the main tank in fol-
lowing ways:
1. Filled through tank lid.
2. Filled by diaphragm pump through suction side fitted
filling device (optional extra) by normal pump capac-
ity directly to the tank.
3. Filled by diaphragm pump through pressure side
fitted injector/venturi type Fast Filling Device (op-
tional extra) by up to 3 times normal pump capacity.
4. Combination of 2 and 3.
The tank should normally be filled 2/3with water, before
adding the chemicals - always read instruction at
chemical container!
NOTE! Max. permitted tank content is 2000 kg
(4410 lb) corresponding to 2000 litres (440
imp.gal.) water or appr. 1550 litres (340
imp.gal.) of liquid fertilizers.
Filling through tank lid
Remove tank lid and fill water through strainer to pre-
vent rust or other particles to enter the tank.
It is recommended to use as clean water as possible for
spraying purposes.
WARNING: Do not let the filling hose enter the
tank. Keep it outside the tank, pointing towards
the filling hole. If the hose is lead into the tank
and the water pressure drops at the water sup-
ply plant, chemicals may be
syphoned back and con-
taminate the water supply
lines, plant and well.

Suction Filling Device.
The Suction Filling Device is operated as follows:
1. Ensure spray liquid tank contains at least 50 liters of
water.
2. Remove cover (1) and connect suction hose (2).
3. Turn handle on Pressure Manifold towards Fast
Filler. With the P.T.O. at 540 r/min, the pressure
gauge should indicate about 10 bar.
4. If water is not seen in transfer tube, prime by turning
valve.
5. Keep an eye on liquid level indicator.
6. Turn handle on Pressure Manifold away from Fast
Filler to discontinue filling process.
NOTE: Turn handle towards EC-oper-
ating unit before turning away from
Fast Filler in order to avoid peak pres-
sure blowing the safety valve!
7. Disconnect suction tube (2) and replace cover.
The Filling Device and the Fast Filling Device can be
used simultaneously - this gives even bigger filling
capacity.
WARNING: Do not leave the sprayer whilst
refilling the tank and keep an eye at the level
gauge in order NOT to overfill the tank!
NOTE! Observe local legislation regarding use of Filling
Device. In some areas it is prohibited to fill from open
water reservoirs (lakes, rivers etc.). It is recommended
only to fill from closed reservoirs (mobile water tanks
etc.) to avoid contamination.
WARNING! If suction hose/filter is carried at the
sprayer during spraying, it can be contaminated
by spray drift, which will be transferred to lake/
river when filling!
Filling the Rinsing tank
Remove the tank lid and fill with clean water and re-
place lid.
MANIFOLD SYSTEM
The MANIFOLD SYSTEM is located at the left side of
the sprayer and permits operation of all HARDI optional
extras from this one position. The modular system
facilitates the addition of up to three optional extras on
the suction side and five extras on the pressure side.
Furthermore the suction manifold can be fitted with a
return valve which ensures better draining of the
sprayer before cleaning.
1.Connect suction hose to Suction Manifold.
2.Engage diaphragm pump and set P.T.O. revs. at 540
r/min. Turn handle on Suction Manifold towards Filling
Device.
WARNING! Always engage pump before
turning the valve towards Filling device to avoid
spray liquid streaming back in suction hose
contaminating the water reservoir!
Do not turn handle towards Filling device un less the
pump is working!
3.The tank is now filled by water. Keep an eye on liquid
level indicator.
4.Turn handle on Suction Manifold away from Filling
Device to discontinue filling process.
7.Disconnect suction tube.
NOTE! Observe local legislation regarding use
of Filling Device. In some areas it is prohibited
to fill from open water reservoirs (lakes, rivers
etc.). It is recommended only to fill from closed reser-
voirs (mobile water tanks etc.) to avoid contamination.
WARNING! If suction hose/filter is carried at
the sprayer during spraying, it can be contami-
nated by spray drift which will be transferred to
lake/river when filling!

1. Choose the correct nozzle. TRIPLET nozzle turrets
are turned to the suitable nozzle for the spray pur-
pose. Make sure that all nozzles are the same type
and capacity. See “Spray Technique” book.
2. Open or close lever 5depending on whether pres-
sure agitation is required. (Remember pressure
agitation takes 5% to 10% of pump output).
3. Main ON/OFF switch Ais set towards green.
4. All distribution valves switches Vare set towards
green.
5. Pressure control switch Cis activated until emer-
gency handle 3, stops rotating (minimum pressure).
6. Put the tractor in neutral and adjust the P.T.O. and
thereby the number of revolutions of the pump corre-
sponding to the intended travelling speed.
NOTE: The P.T.O. revolutions must be kept
between 300-600 r/min.
7. Pressure control switch Dis activated till the recom-
mended pressure is shown on the pressure gauge.
ADJUSTMENT OF PRESSURE EQUALIZATION:
8. Close the first distribution valve switch V.
9. Turn the adjusting screw 1until the pressure gauge
again shows the same pressure.
10.Adjust the other sections of the distribution valve in
the same way.
Hereafter adjustment of pressure equalization will
only be needed if you change to nozzles of other
capacities.
OPERATING THE CONTROL UNIT WHILE DRIVING:
11.To stop the liquid flow to the boom switch ON/OFF A
to OFF position. This returns the pump output to the
tank through the return system. The diaphragm anti-
drip valves ensure instantaneous closing of all
nozzles.
To stop the liquid flow to one or more boom sections,
switch the relevant distribution valve Vto OFF posi-
tion. The pressure equalization ensures that the
pressure does not rise in the sections which are to
remain open.
If 2 or more valves are fitted, the arrow must point
towards the optional extra you select. Remaining
handles are turned to “O” (closed). When spraying is to
resume, select the Self-Cleaning Filter/operating unit.
The other handles are turned to “O”.
If all the green pressure valves are closed the safety
valve will open inside the tank.
Black suction valves
Turn the handle so the
arrow points towards
the selected optional
equipment. The handle
is turned back when
you want to aspirate
from the main tank.
If 2 valves are fitted, eg. Front Tank and Rinsing Tank,
select optional extra and turn the other valve to “O”
(closed). To resume aspiration from the main tank, the
arrow must point towards the main tank. Remaining
valve must be closed.
Blue return valve
Normally the liquid is directed to the tank return. When
the tank is nearly empty, the handle is turned so the
liquid is directed to the suction side of the pump instead
of the tank return.
Adjustments of EC operating unit
Before spraying the EC operating unit is adjusted using
clean water (without chemicals).

Choice of restrictor
It is important to have a large flow
through the filter. This is achieved by
choosing the restrictor size in relation to
the liquid consumption of the spray boom.
4 restrictors are supplied. Use the green
one (largest Aorifice first).
Hose Nis unscrewed from the filter. Be
careful not to loose the seal. The restric-
tor is placed in the hose and the hose is
mounted again.
If the required working pressure cannot
be obtained, the restrictor is too large.
Choose a smaller restrictor. Start with a
black one, then a white and finally a red one.
When cleaning the filter remove hose Nand the hose at
the safety valve and check there are no residues.
Standard filter size is 80 mesh. Filters of 50 and 100
mesh are available. To remove filter mesh undo the
large ring nut. Check condition and placement of
O-rings before reassembly.
Filling of chemicals
Chemicals can be filled in the tank in 2 ways:
1. Through tank lid
2. By means of HARDI FILLER chemical filling device
(optional extra in some countries).
Warning! Be carefull not to slip or splash
chemicals when carrying chemicals up to the
tank lid!

Operation of rinsing tank.
The front mounted 200 l rinsing tank can be used for
two purposes:
A.In-field diluting of remaining spray liquid residues in
the main tank for spraying the liquid in the field, before
cleaning the sprayer.
1. Turn suction valve towards rinsing tank.
2. Turn pressure valves towards rinsing nozzle (if fitted).
3. When rinsing tank is empty, turn back suction valve
towards suction from main tank and operate all
valves, so all hoses and components are rinsed.
4. Turn pressure valve back to EC-operating unit and
spray liquid in the field you have just sprayed.
B.Rinsing the pump, operating unit, spray lines etc. in
case of stop in spraying before main tank is empty (e.g.
beginning rain etc.).
1. Turn suction valve towards rinsing tank
2. Turn blue return valve (if fitted) towards pump suc-
tion line
3. Spray water from rinsing tank out in the field until all
nozzle tubes/nozzles are flushed with clean water.
Operation of the tank drain valve
Pull the red handle on the side of the tank to open the
drain valve. The valve is spring-loaded, but can be kept
open by pulling the string out and upwards in the V-
shaped slit. To release, pull the string downward and
the valve will close automatically.

Maintenance
In order to derive full benefit from the sprayer
for many years the following few but important
rules should be kept:
Cleaning the sprayer
Guidelines
Read the whole label of the chemical. Take
note of any particular instructions regarding
recommended protective clothing, deactivating agents,
etc. Read the detergent and deactivating agent labels. If
cleaning procedures are given, follow them closely.
Be familiar with local legislation regarding disposal of
pesticides washings, mandatory decontamination meth-
ods, etc. Contact the appropriate body, eg. Dept of
Agriculture.
Pesticide washings can usually be sprayed out on a
soakaway. This is an area of ground that is not used for
cropping. You must avoid seepage or run-off of resi-
dues into streams, water courses, ditches, wells,
springs, etc. The washings from the cleaning area must
not enter sewers. Drainage must lead to a soakaway.
Cleaning starts with the calibration, as a well calibrated
sprayer will ensure the minimal amount of remaining
spray liquid.
It is good practice to clean the sprayer immediately after
use thereby rendering the sprayer safe and ready for
the next pesticide application. This also prolongs the life
of the components.
It is sometimes necessary to leave spray liquid in the
tank for short periods, eg. overnight, or until the weather
becomes suitable for spraying again. Unauthorized
persons and animals must not have access to the
sprayer under these circumstances.
If the product applied is corrosive, it is recommended to
coat all metal parts of the sprayer before and after use
with a suitable rust inhibitor.
Remember: Clean sprayers are safe sprayers.
Clean sprayers are ready for action.
Clean sprayers can not be damaged by
pesticides and their solvents.
Cleaning
1. Dilute remaining spray liquid in the tank with at least
10 parts water and spray the liquid out in the field
you have just sprayed.
NOTE: It is advisable to increase the forward
speed (double if possible) and reduce the pres-
sure. For S4110 nozzles, pressure may be
reduced to 1.5 bar.
2. Select and use the appropriate protective clothing.
Select detergent suitable for cleaning and suitable
deactivating agents if necessary.
3. Rinse and clean sprayer and tractor externally. Use
detergent if necessary.
4. Remove tank and suction filters and clean. Be care-
ful not to damage the mesh. Replace suction filter
top. Replace filters when the sprayer is completely
clean.
5. With the pump running, rinse the inside of the tank.
Remember the tank roof. Rinse 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, decide whether this should be done in
the field again or on the soakaway.
6. After spraying the liquid out, stop the pump and fill at
least 1/5 of the tank with clean water. Note that some
chemicals require the tank to be completely filled.
Add appropriate detergent and/or deactivating agent,
eg. Washing soda or Triple ammonia.
NOTE: If a cleaning procedure is given on the
chemical label, follow it closely.
7. Start the pump and operate all controls enabling the
liquid to come in contact with all the components.
Leave the distribution valves until last. Some deter-
gents and deactivating agents work best if left in the
tank for a short period. Check the label.
The Self-Cleaning Filter can be flushed by removing
the bypass hose from the bottom of the filter. Stop
the pump and remove the hose. Start the pump for a
few seconds to flush filter. Be careful not to loose the
restrictor nozzle.
8. Drain the tank and let pump run dry. Rinse inside of
tank, again letting the pump run dry.
9. Stop the pump. If the pesticides used have a ten-
dency to block nozzles and filters, remove and clean
them now. Check also for sediment on the pressure
side of the safety valve for the
Self-Cleaning Filter.
10.Replace all the filters and nozzles and store the
sprayer. If, from previous experiences, it is noted that
the solvents in the pesticide are particularly aggres-
sive, store the sprayer with the tank lid open.
NOTE: If the sprayer is cleaned with a high
pressure cleaner we recommend lubrication of
the entire machine.
Cleaning and maintenance of filters
Clean filters ensure :
•Sprayer components such as valves, diaphragms
and operating unit are not hindered or damaged
during operation.
•Nozzle blockages do not occur whilst spraying.
•Long life of pump. A blocked suction filter will result
in pump cavitation.
