The HARDI sprayer is for the application of crop protection chemicals and liquid fertilisers. The equipment must onlybe used for this purpose. It is not allowable to use the sprayer for other purposes. If no local law demands that theoperator must be certified to use spray equipment, it is strongly recommended to be trained in correct plant protec-tion and in safe handling of plant protection chemicals to avoid unnecessary risk for persons and the environmentwhen doing your spray job.

When driving on public roads and other areas where the highway code applies, or areas where there are special rulesand regulations for marking and lights on implements, you should observe these and equip implements accordingly.

With the adjustable Agitation valve it is possible to combine sprayingwith a high volume rate at high pressure with agitation at same time.This is controlled continously on the valve: The valve is marked withan arrow on the disc that indicates the amount of liquid that passesthrough the valve. If the handle is turned to a position near the tip ofthe arrow, then only a small amount of liquid is allowed to pass thevalve resulting to a lesser extent of agitation. Otherwise if the handleis turned to a position in the wide end of the arrow then a largeamount of liquid will pass the valve resulting to a large extent of agi-tation.

The valve is used simultaneously with the ChemFiller. Open valvewhen chemicals is going to be filled into the ChemFiller. Note thatsuction SmartValve must be positioned at “Suction from Main tank”to make the valve work.

The valve is used when filling from an external tank or reservoir.Activating valve starts/stops the filling proces. Note that suctionSmartValve must be positioned at “Suction from Main tank” or “suc-tion from an external source” to make the valve work.

This valve activates the Vortex flushing of the ChemFiller. The valve issituated behind the ChemFiller and is only visible when ChemFiller isfolded down in use position.

ATTENTION! The LookAhead system is only activated when using if supported by the spray controller.

The system is based on EFC - Electrical Fluid Control. The LookAhead control unit is constructed of modules and iselectrically controlled via a remote control box.

The built-in HARDI-MATIC ensures a constant volume per hectare of the liquid (l/ha) at varying forward speed withinthe same gear when the number of P.T.O. revolutions are between 300-600 r.p.m. (pump 540 r.p.m) or 650-1100r.p.m. (pump 1000 r.p.m.).

EFC - Electrical Fluid Control. The ON/OFF is linked to the section valves, which results in a very quick response toON/OFF. The operating unit is constructed of modules and is electrically controlled via a remote control box.

A EasyClean suction filter is fitted in the working zone near the Smart Valves. It has a built-in valve that closes whenthe filter is opened for inspection or cleaning.

A Cyclone pressure filter is fitted to the sprayers right side just behind the handbrake. It has a built-in self-cleaningfunction.

In-line pressure filters can be fitted at each section as an option.

Nozzle filters are fitted at each nozzle.

All filters should always be in use and their function checked regularly. Pay attention to the correct combination of filterand mesh size. The mesh size should always be less than the flow average of the nozzles in use.

The ChemFiller is situated in the working zone on the sprayers leftside, just behind the MANIFOLD valves. When being used itshould be folded down by grabbing the handle, then unlock it bypushing the grib just below the handles left side and pulling itagainst yourself.

When retracting the ChemFiller after use, then unlock it by pushingthe grib just below the handles left side and push it back in storingposition until a click is heard. Then ChemFiller is locked into thestorage position.

When folded down in use position a grip for chemical containercleaning and a valve for ChemFiller Vortex nozzle are visible on thebackside of the ChemFiller.

DANGER! Suction SmartValve must always be turned to the unused position and turn the pressure SmartValveto “Main tank” (both levers pointing forward) before opening the Cyclone filter! If not then spraying liquid can hityou when opening the filter and drain from the tank!

Valve (5) has three positions marked with small dots on the lever:

Position A (Marked with 1 dot): There is no return flow. Position isused when rinsing the boom if there is spray liquid in the maintank. Also used when high spraying volume is required.

Position B (Marked with 2 dot): Normal spraying position. Withreturn flow to prevent filter is going to be clogged when spraying.Position is used when rinsing the boom if the main tank is empty.

Position C (Marked with 3 dot): Flushing position which are used iffilter is clogged. Lift and hold the lever to use this position whichlargely increases return flow and cleans the filter.

The EasyClean filter is fitted in the working zone near the SmartValves. It has a built-in valve that automatically closes when the fil-ter is opened for inspection and cleaning. To open filter then turn itcounterclockwise and pull it up, like shown on picture.

Beside the spray pressure gauge on the platform a EasyCleanclogging indicator is located.

Green indicator: No cleaning necessary.

Yellow indicator: It is possible to finish an ongoing spraying job andthen clean filter afterwards.

Red indicator: Clean EasyClean filter immediately as filter is clog-ged.

With the CycloneFilter the impurities that exist in the spray liquidwill by-pass the filter and be recirculated back to the tank via thereturn flow.

3.11

DANGER! No persons are allowed in the operations area of the sprayer when steering is unlocked!

WARNING! Never articulate steering when boom is in transport position.

Please see seperate instruction book for track calibration and operation.

This articulated trailer behaves differently than a normal trailer. Intracking position the vehicle centre of gravity is displaced moreforward compared to the vehicle centre line of a normal trailer.Compared to a conventional trailer with steering drawbar this arti-culated trailer has increased stability when turning, especially whenturning on hillsides.

To avoid overbalancing, pay attention to these guidelines:

1. Avoid sudden, tight turns.

2. Slow down before entering a curve or turning, and drive with aconstant, low speed during the turn.

3. Never slow down too fast, never brake heavily and never stopsuddenly in a curve, or when turning on a hillside, when the spray-er is articulated.

4. Be careful when turning on uneven ground.

5. Set the track gauge as wide as possible.

6. The proper function of the hydraulic system is essential toobtain good stability.

7. For safety reasons, the following limitations are set for the arti-culated trailer (with unfolded booms):

Speed by turning, max. 4 km/h (2.5 m.p.h.)

Ground inclination by turning, max. 8°

Track gauge, min. Please see the part “Altering the trackgauge”

Although the sprayer has been applied with a strong and protective surface treatment on steel parts, bolts etc. in thefactory, it is recommended to apply a film of anticorrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) onall metal parts in order to avoid chemicals and fertilisers discoloring the enamel. If this is done before the sprayer isput into operation for the first time, it will always be easy to clean the sprayer and keep the enamel clean for manyyears. This treatment should be carried out every time the protection film is washed off

The support leg is stored in retracted position and secured by thespring loaded linch pin when the sprayer is attached to the tractor.

To retract the support leg: Lift the leg, then pull the linch pin andtilt up the support leg until the linch pin “clicks” into the upper loc-king hole. Then push the crank handle down and turn it so thehandle will rest on the support leg.

DANGER! ROTATING TRANSMISSION SHAFTS WITHOUT PROTECTION GUARDS ARE FATAL.

WARNING! The shaft must always have a minimum overlap.

The size of this overlap depends on the pump model:

1. Always STOP ENGINE before attaching the transmission shaft to tractor P.T.O. - most tractor P.T.O. shafts can berotated by hand to facilitate spline alignment, when engine is stopped.

2. When attaching the shaft, make sure that the snap lock is FULLY ENGAGED - push and pull shaft until it locks.

3. Always keep protection guards and chains intact and make sure that it covers all rotating parts, including CV-jointsat each end of the shaft. Do not use without protection guard.

4. Do not touch or stand on the transmission shaft when it is rotating - safety distance: 1.5 meter.

5. Prevent protection guards from rotating by attaching the chains allowing sufficient slack for turns.

6. Make sure that protection guards around tractor P.T.O. and implement shaft are intact.

7. Always STOP ENGINE and remove the ignition key before carrying out maintenance or repairs to the transmissionshaft or implement.

The extension piece is inserted into the opening for the drawbar,fastened by three main bolts through the three holes (A) and secu-red by locknuts.

DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the systemwhich can cause violent movements of the boom.

DANGER! Hydraulic leaks: Never use your fingers to locate a leakage in any part of the hydraulic system. Dueto high pressure, hydraulic oil may penetrate the skin.

Ensure that snap couplers are clean before connection!

After having operated the boom and the system has been filled with oil, check tractor’s hydraulic oil level and top up ifnecessary.

The hydraulic system requires a double acting hydraulic outlet. The hydraulic hoses are marked with arrows to indica-te direction of oil flow.

The hydraulic system requires an oil flow between 10 and 90 l/min (19.8 Imp. gal/min.) and a min. pressure of 170bar (2466 p.s.i.). The system has a built-in flow regulator that maintains constant speed on hydraulic movements.

DANGER! It is very important that the CaCl2 is added to the water and agitated until it is fully dissolved. Neverpour water on to CaCl2! If you get CaCl2 in the eyes, flush instantly with cold water for at least 5 minutes andseek medical advice afterwards.

WARNING! The tyres must be liquid filled to max. 75 % of total tyre volume. Fill only the qty. of liquid necessaryto obtain sufficient stability of the sprayer. Do not fill liquid and CaCl2 mixture in tyres without tubes!

ATTENTION! When filling the tyres the valve should be positioned at 12 o’clock and when adjusting the tyrepressure, the valve should be positioned at 6 o’clock.

ATTENTION! Disposal of CaCl2 has to take place according to local legislation.

TO EMPTY THE TYRES:

1. Rotate wheel till the valve is positioned at “6 o’clock”.

2. Remove the valve body and let out the liquid. Retain liquid in anappropriate container.

3. To empty the tyre completely the tyre is inflated and a thin draintube is lead to the bottom of the tyre. The air pressure will nowempty the remaining liquid.

4. Remove the drain tube, fit the valve and inflate the tyre to speci-fied pressure. See the table “Tyre pressure”.

To improve stability on articulated models, extra weight can beadded by means of liquid-filled tyres. The standard tyre valve is anuniversal air-water valve. The tyres can be filled with liquid to max.75% of their total volume.

Use a mixture of water and CaCl2 to avoid frost damage as des-cribed below:

200 g (7.1 oz) CaCl2 per litre water gives protection to -15°C(30.6°F)

300 g (10.6 oz) CaCl2 per litre water gives protection to -25°C(12.6°F)

435 g (15.4 oz) CaCl2 per litre water gives protection to -35°C (-5.4°F)

TO FILL THE TYRES:

1. Jack up the wheel and rotate wheel till the valve is positioned at“12 o’clock”.

2. Remove the valve body and fill liquid until it reaches the valve.

3. When surplus liquid is drained through the valve stem fit thevalve body again.

4. Adjust tyre pressure and lower the wheel. (Please refer to tablefor correct tyre pressure).

The boom suspension will normally suit most conditions and donot require any adjustment. The suspension will keep the boomparallel to the ground and compensate for uneven ground.

However, special conditions or situations can require the suspen-sion to react less or more slowly. In order to alter the behavior ofthe boom depending on field where the sprayer will be used (une-ven, hilly etc. ground), damper adjustment is needed at the lowerguiding rods. The fixture of the two lower guiding rod arms can beadjusted.

1. Remove the four bolts.

2. Rotate the fixture 180° towards the centre.

3. Fasten the fixture in this new position.

If even further damper adjustment is needed the above procedurecan be repeated on the two upper guiding rods.

When altered the guide rod setting in “Suspension performanceadjustment” then it is possible to adjust more accurately in thefield. This is done with the electrical damping control, which issituated at the centre section of the boom.

When the throttle valve (A) is screwed all the way in, followed bythree reverse turns out (factory setting), the boom suspension willreact immediately, and the boom will move independently of thetrailer or tractor.

To obtain more damping: Throttle valve (A) must be screwedinward.

To obtain less damping: Throttle valve (A) must be screwed out-ward.

ATTENTION! Always read the individual paragraphs. Read instructions for service/maintenance jobs carefullybefore starting on the job. If any portion remains unclear or requires facilities which are not available, then forsafety reasons please leave the job to your HARDI dealer’s workshop.

ATTENTION!

Clean sprayers are safe sprayers.

Clean sprayers are ready for action.

Clean sprayers cannot be damaged by pesticides and their solvents.

Guidelines

1. Read the whole chemical label. 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, followthem closely.

2. Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods,etc. Contact the appropriate department, e.g. Dept. of Agriculture.

3. Pesticide washings can usually be sprayed out on a soakaway. This is an area of ground that is not used for crop-ping. You must avoid seepage or runoff of residue into streams, water courses, ditches, wells, springs, etc. The was-hings from the cleaning area must not enter sewers. Drainage must lead to an approved soakaway.

4. Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining sprayliquid.

5. It is good practice to clean the sprayer immediately after use and thereby rendering the sprayer safe and ready forthe next pesticide application. This also prolongs the life of the components.

6. It is sometimes necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weatherbecomes suitable for spraying again. Unauthorised persons and animals must not have access to the sprayer underthese circumstances.

7. If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after usewith a suitable rust inhibitor.

In order to derive full benefit from the sprayer for many years the following service and maintenance program shouldbe followed.

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 the pump. A blocked suction filter will result in pump cavitation. The main filter protecting sprayer com-ponents is the suction filter. Check it regularly.

ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manuallywith a brush afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed after-wards!ATTENTION! It is advisable to increase the forward speed (double if possible) and reduce

the pressure to 1.5 bar (20 psi).

The incorporated rinsing tank can be used for two different purposes.

A. In-field diluting of remaining spray liquid residue in the spraying circuit for spraying the liquid in the field, before cle-aning the sprayer. This cleaning procedure is divided in three main steps:

Cleaning of the liquid system:

1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of allnozzles.

2. Turn Suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Main tank”.

3. Engage and set the pump at approximately 300 r.p.m.

4. When 1/3 of content in rinsing tank are used, turn Suction SmartValve towards “Main tank” and operate all valveson the pressure side of the system in the following order, so all hoses and components are rinsed: Open ChemFillersuction valve, open ChemFiller Vortex nozzle and close it again when clean water comes out of nozzles. CloseChemFiller lid and squeeze the Chemical Container Cleaning handle to clean this device. Open ChemFiller lid againand assure that ChemFiller is empty. When empty then close the ChemFiller suction valve again.

5. Turn the suction SmartValve towards “Main tank” and pressure SmartValve towards “Spraying” and spray liquid inthe field you have just sprayed.

Cleaning of Main tank:

6. Turn the suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Internal Tank Cleaning”.

7. When another 1/6 of content in rinsing tank are used, then turn suction SmartValve towards “suction from Maintank”.

8. Turn pressure SmartValve towards “Spraying” and spray liquid in the field you have just sprayed.

9. Repeat point 6 - 8 one more time.

Outwards cleaning:

10. Turn suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Internal Tank Cleaning”.

11. When another 1/3 of content in rinsing tank are used, then turn suction SmartValve towards “Main tank”.

12. Turn pressure Agitation valve towards “External Cleaning Device” and wash the sprayer with the cleaning devicelocated on sprayers right side.

13. Disengage pump again.

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.).

Cleaning of the liquid system:

1. Turn Suction SmartValve towards “Rinsing tank”. (Keep pressure SmartValve in “Spraying”-position).

2. Close AgitationValve (no agitation).

3. Engage the pump and spray water from rinsing tank in the field until all nozzle tubes/nozzles are flushed with cleanwater.

4. Disengage pump again.

Inevitably a quantity of spray liquid will remain in the system. It cannot be sprayed properly on the crop, as the pumptakes in air when the tank is about to be empty.

This Technical Residue is defined as the remaining liquid quantity in the system as the first clear pressure drop on thepressure gauge is read.

The residue of the individual sprayers are to be taken from the table.

36 m 9 68,9 l 69,7 l

The values are measured with sprayer in level and apply to the complete equipment. During slope inclinations to 20 %these values remain constant. The residues in the tank should be diluted immediately in the relationship 1:10 withwater and afterwards be sprayed to the crop just sprayed with increased driving speed. In addition the rinsing tank isto be used, with this can also pump, linkage and armature separately be rinsed. It is to be made certain however thatthe liquid in the lines in unchanged concentration is sprayed out, so there should be an untreated patch available.

DANGER! Non observance of mounting instructions will result in the bad seating of the tyre on the rim andcould cause the tyre to burst leading to serious injury or death!

DANGER! Never mount or use damaged tyres or rims! Use of damaged, ruptured, distorted, welded or brazedrim is not allowed!

Should it be necessary to replace tyres, it is recommended to leave this to a specialist and follow the mentioned rules.

1. Always clean and inspect the rim before mounting.

2. Always check that the rim diameter corresponds exactly to the rim diameter moulded on the tyre.

3. Always inspect inside of the tyre for cuts, penetrating objects or other damages. Repairable damages should berepaired before installing the tube. Tyres with unrepairable damages must never be used.

4. Also inspect inside of the tyre for dirt or foreign bodies and remove it before installing the tube.

5. Always use tubes of recommended size and in good condition. When fitting new tyres always fit new tubes.

6. Before mounting, always lubricate both tyre beads and rim flange with approved lubricating agent or equivalentanti-corrosion lubricant. Never use petroleum based greases and oils because they may damage the tyre. Using theappropriate lubricant the tyre will never slip on the rim.

7. Always use specialised tools as recommended by the tyre supplier for mounting the tyres.

8. Make sure that the tyre is centred and the beads are perfectly seated on the rim. Otherwise danger of bead wiretear can occur.

9. Inflate the tyre to 100-130 kPa (14.5-19 p.s.i.) then check whether both beds are seated perfectly on the rim. If anyof the beads do not seat correctly, deflate the assembly and re-centre the beads before starting inflation of the tyre. Ifthe beads are seated correctly on the rim at 100-130 kPa inflate the tyre to a maximum of 250 kPa (36 p.s.i.) untilthey seat perfectly on the rim.

10. Never exceed the maximum mounting pressure moulded on the tyre!

11. After mounting tyres adjust inflation pressure to operation pressure recommended by the tyre manufacturer.

12. Do not use tubes in tubeless tyres.

When the spraying season is over, you should devote some extra time to the sprayer. If chemical residue is left over inthe sprayer for longer periods, it can reduce the life of the individual components. To preserve the sprayer intact andto protect the components, carry out following off-season storage program.

1. Clean the sprayer completely - inside and outside - as described under “Cleaning of the sprayer”. Make sure thatall valves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards,so no chemical residue is left in the sprayer.

2. Renew possible damaged seals and repair possible leaks.

3. Empty the sprayer completely and let the pump work for a few minutes. Operate all valves and handles to drain asmuch water off the spraying circuit as possible. Let the pump run until air is coming out of all nozzles. Remember todrain the rinsing tank also.

4. Pour appr. 50 litre (11 Imp.gal) anti-freeze mixture consisting of 1/3 automotive anti-freeze and 2/3 water into thetank.

5. Engage the pump and operate all valves and functions on the MANIFOLD, operating unit, chemical inductor etc.allowing the anti-freeze mixture to be distributed around the entire circuit. Open the operating unit main on/off valveand distribution valves so the anti-freeze is sprayed through the nozzles as well. The anti-freeze will also prevent O-rings, seals, diaphragms etc. from drying out.

6. Lubricate all lubricating points according to the lubricating scheme - regardless of intervals stated.

7. When the sprayer is dry, remove rust from possible scratches or damages in the paint and touch up the paint.

8. Remove the glycerine-filled pressure gauges and store them frost free in vertical position.

9. Apply a thin layer of anti-corrosion oil (e.g. SHELL ENSIS FLUID, CASTROL RUSTILLO or similar) on all metalparts. Avoid oil on rubber parts, hoses and tyres.

10. Fold the boom in transport position and relieve pressure from all hydraulic functions.

11. All electric plugs and sockets are to be stored in a dry plastic bag to protect them against damp, dirt and corro-sion.

12. Remove the control boxes and computer display from the tractor, and store them dry and clean (in-house).

13. Wipe hydraulic snap-couplers clean and fit the dust caps.

14. Apply grease on all hydraulic ram piston rods which are not fully retracted in the barrel to protect against corro-sion.

15. Chock up the wheels, to prevent moisture damage and deformation of the tyres. Tyre blacking can be applied tothe tyre walls to preserve the rubber.

16. Drain air brake tank for condensed water.

17. To protect against dust the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.

7 - Fault finding

7.1

Operational problems

In cases where breakdowns have occurred, the same factors always seem to come into play:

1. Minor leaks on the suction side of the pump will reduce the pump capacity or stop the suction completely.

2. A clogged suction filter will hinder or prevent suction so that the pump does not operate satisfactorily.

3. Clogged up pressure filters will result in increasing pressure at the pressure gauge but lower pressure at the nozz-les.

4. Foreign bodies stuck in the pump valves with the result that these cannot close tightly against the valve seat. Thisreduces pump efficiency.

5. Poorly reassembled pumps, especially diaphragm covers, will allow the pump to suck air resulting in reduced or nocapacity.

6. Hydraulic components that are contaminated with dirt result in rapid wear to the hydraulic system.

Therefore ALWAYS check:

1. Suction, pressure and nozzle filters are clean.

2. Hoses for leaks and cracks, paying particular attention to suction hoses.

3. Gaskets and O-rings are present and in good condition.

4. Pressure gauge is in good working order. Correct dosage depends on it.

5. Operating unit functions properly. Use clean water to check.

6. Hydraulic components are maintained clean.
