Liquid system
Pump
Diaphragm pump with 6 diaphragms, model 363. Standard 540 r.p.m. pump for 6 splines transmission shaft. The design of the diaphragm pump is simple, with easily accessible diaphragms and valves which ensures liquid does not contact the vital parts of the pump.
Valves and symbols
The valves of the valve system are distinguished by coloured identification on the function labels. Symbols corresponding to every possible function of use are located on the discs for easy identification and operation. The modular MANIFOLD system facilitates the addition of optional extras on both pressure side and suction side. Furthermore the suction manifold can be fitted with a return valve which ensures better draining of the sprayer before cleaning. A function is activated by turning the handle towards the desired function. The valves are:
A. Agitation valve (optional equipment)
B. Pressure valve
C. Return valve
D. Suction valve
E. External filling device valve (optional equipment)
(D) Suction valveWith this valve you select from where the pump sucks the liquid.
Turn the handle so the indicator points towards the label of the required function. If the handle is turned to vertical position (indicator not pointing to a label), the valve is closed.
(B) Pressure valveWith this valve you select which function the pressurized liquid from the pump will be directed to.
The active function is indicated by the indicator. Turn the handle so that the indicator points to the label of the required function. If the handle is turned to a label-free position (unused function), the valve is closed.
(C) Return valveWith this valve you select whether return liquid should be directed back to the main tank or to the pump. 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 in order to fully emptying the tank prior to cleaning.
(A) Agitation valve (optional)With the adjustable Agitation valve you can combine high volume rate spraying at high pressure with simultaneous agitation, i.e. it is possible to continuously adjust the amount of fluid from the pump that is used for agitation in the tank and for spraying.The valve is marked with an arrow on the disc indicating the amount of liquid passing through the valve. If the handle is turned to a position near the tip of the arrow, only a small amount of liquid passes through the valve, resulting in reduced

agitation. Conversely, if the handle is turned to a position in the wide end of the arrow, a large amount of liquid passes through the valve, resulting in increased agitation.
Illustrations of handle positions at different agitation quantities:
1. Handle is in the “widest end of arrow” position (fully open). Agitation quantity is 100%.
2. Handle is positioned at the middle of the arrow. Agitation quantity is 50%.
3. Handle is positioned in closed position. Agitation quantity is 0%.
(E) External Filling Device valve (optional)The valve is used when filling from an external tank or reservoir.
Activating valve starts/stops the filling process. Note that the suction valve must be closed for maximum filling capacity.
μ ATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be serviced. Please see the section ‘Maintenance’ for further information.
Control unit
The sprayer is equipped with an EVC control unit.
The system is based on EVC - Electrical Valve Control. The ON/OFF is linked to the section valves, which is results in a very quick response to ON/OFF. The operating unit is constructed of modules and is electrically controlled via a remote control box.
With HARDI-MATIC that ensures a constant liquid volume per hectare (l/ha) at varying forward speed within the same gear when the number of P.T.O. revolutions are between 300-600 r/min.

Boom
Boom and terminology
The sprayer is fitted with a VPZ boom. The boom is supported by a trapeze fitted to the tank frame.
The trapeze helps the boom to stay horizontal when unfolded and it protects the boom against vibrations and shocks when driving on uneven ground. This ensures longer boom life and improves boom stability for better spray distribution.
Booms are available in 20, 21 and 24 m working width. All booms are provided with spring loaded breakaway.
For 3-folded booms the terminology is as follows:A - Breakaway section
B - Outer section
C - Intermediate section
D - Inner section
E - Centre section
3 - Description
23
Equipment
Nozzle pressure gauge
The remote pressure gauge is integrated at the front of the sprayer. This gauge measures the working pressure in the boom tubes as close to the nozzles as possible.
The outputs stated in the nozzle charts are always based on the pressure measured at the nozzle. Always adjust the pressure when calibrating and spray according to the readings at the remote pressure gauge.
Footboard (optional)
The footboard gives access to the main tank lid. It ensures easy access for filling of sprays, cleaning of tank, etc.
Safety locker (optional)
A safety locker can be mounted underneath the footboard for storage of safety gear such as non-contaminated protective gear, soap for hand washing etc. The locker is split in two compartments for the separation of clean clothes from gloves with risk of contamination.
± WARNING! Although this locker is meant for the storing of non-contaminated items, it must never be used for the storing of food, beverage or other items meant for consumption.
Tank level indicator
The actual tank level in the main tank can be observed on the tank level indicator. The scale is displayed in litres or Imp. gal/US gal. (certain countries).
3 - Description
24
External Cleaning Device (optional)
This equipment comprises a hose reel and spray lance used to clean the complete sprayer externally in the field with clean water. The External Cleaning Device is located on the boom centre section at the back side.
± WARNING! The Cleaning Device produces a high pressure and incorrect use may result in personal injuries!
€ DANGER! Never work in bare feet or sandals. It is recommended to wear goggles during the work. It is recommended that the user or anyone near the cleaning place protects himself against particles bouncing up during the cleaning.

4 - Sprayer setup
General info
Before putting the sprayer into operation
Although the sprayer has been supplied with a strong and protective surface treatment on steel parts, bolts etc. in the factory, it is recommended to apply a film of anticorrosion oil (e.g. CASTROL RUSTILO or SHELL ENSIS FLUID) on all metal parts in order to avoid chemicals and fertilizers discoloring the enamel.
If this is done before the sprayer is put into operation for the first time, it will always be easy to clean the sprayer and keep the enamel clean for many years. This treatment should be carried out every time the protection film is washed off.
Unloading the sprayer from the truck
For the unloading of the sprayer, you need a crane. When unloading with a crane please observe the lifting points as shown in the picture, and make sure that the straps or belts used for lifting are strong enough.
μ ATTENTION! Only lift the sprayer when the tanks are empty!
Counter balance
μ ATTENTION! Note the weight of the sprayer. General recommendations are as follows:
1. Add ballast to the front of the tractor, if necessary.
2. Check tyre pressure (see tractor’s instruction book).
3. Be careful when filling/lifting the sprayer for the first time.
4. Ensure that the operating unit and the tractor do not touch.
5. Travel at slower speeds when driving with a full tank, as the tractor braking effect will be reduced.

Transmission shaft
Operator safety
1. Always STOP THE ENGINE before attaching the transmission shaft to the tractor P.T.O. - most tractor P.T.O. shafts can be rotated by hand to facilitate spline alignment, when the engine is stopped.
2. When attaching the shaft, make sure that the snap lock is FULLY ENGAGED - push and pull the shaft until it locks.
3. Always keep protection guards and chains intact and make sure that it covers all rotating parts, including CV-joints at 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. Also NEVER cross over a rotating P.T.O. shaft to reach the other side of the sprayer.

Hydraulic systems
General info
Ensure that the snap couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check the tractor’s hydraulic oil level and top up, if necessary.
€ DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which 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. Due to high pressure, hydraulic oil may penetrate the skin.
Requirements - tractor (VPZ model)
The hydraulic system requires:
• One double-acting outlet for the electro-hydraulic operation of the boom functions.
Models without electrical activated boom lift also require:
• One single-acting outlet to raise and lower the boom.
The hydraulic hoses are marked with arrows to indicate the direction of oil flow.
The hydraulic system requires an oil flow between 25 and 130 l/min (5.5 - 28.6 Imp. gal/min.) and a min. pressure of 170 bar (2500 p.s.i.).
Open centre hydraulics (optional)
The open centre hydraulics block is needed if the tractor uses open centre hydraulics and/or if load sensing will be used.
Model without electrical activated boom liftThe valve on the side of the block is factory set for open centre hydraulics, but if closed centre hydraulics will be used (also in combination with load sensing), screw in the valve.
± WARNING! Before operating the hydraulics, the valve should be adjusted according to the specific tractor model. If you are unsure of the type of hydraulic system in your tractor, please contact your tractor dealer.
± WARNING! Always be sure to fully extract or retract the open/closed center selection valve. Failure to do so may cause damage to vital pump parts.
Load sensing hydraulicsCertain tractor models are able to use Load Sensing using an external sensing line (1/4” hose) directly from the tractor to the boom hydraulic block. If fitted, the LS outlet on the boom hydraulic block must be restricted using an 1/4” niple with an 0.7 mm orifice (Hardi part no. 146851).

Power supply
Power requirement is 12V DC. Always note polarity! For proper function of the electric equipment, the wires must have the following recommended cross sectional areas and correct fuses to ensure a sufficient power supply. The delivered power connectors follows the standard of most newer tractors. If you have a tractor with another power connector, it is necessary to disassemble the connector and fit it to the actual tractor connector.
The number and the type of connectors may vary on the specific sprayer, depending on its equipment.
Speed transducer for tractor
For tractors without speedometer. Note the following if the speed transducer is fitted to the tractor.
The speed transducer and the speed ring should be located at the inside of the tractor’s right wheel. The sensor is an inductive type that requires a metallic protrusion (e.g. bolt head) passing by in order to trigger a signal. It should be adjusted so transducer is placed to the centre of the holes in the speed ring (vertical direction). Recommended distance between protrusion and transducer (A) is 3 to 6 mm. Check this in the entire circumference.
Correct fitting is indicated by constant flashing of the transducer when the wheel rotates.

Filling/washing location requirements
When filling the sprayer with chemicals and water it is important to avoid spot contamination by spray chemicals in order to protect the subsoil water resources.
A. If the sprayer is always filled at the same place, a special filling/washing location should be established. This should have a hard, liquid-impenetrable surface (e.g. concrete) securing against seepage and edges securing against run-off to the surrounding areas. The place should be drained to an adequate receptacle (e.g. slurry tank or similar).
Any spillage or washings should be retained and diluted in order to be distributed on a larger area to ensure minimal environmental impact and avoid build-up of larger chemical concentrations at one spot.
If no other requirements of distances exist, the following general recommendation of distance could be used. Not closer than:
1) 50 metres from public water supplies for drinking purposes,
2) 25 metres from non-public water supplies for drinking purposes and from treatment sumps and cesspools of drainage systems, and
3) 50 metres from surface water (watercourses, lakes and coastal waters) and from nature reserves.
B. Alternatively the sprayer can be filled in the field where the spraying is to take place. If so, choose a different location for each refilling.
If no other requirements of distances exist, the filling should not be established closer than:
1) 300 metres from public or non-public water supplies for drinking purposes and
2) 50 metres from surface water (watercourses, lakes and coastal waters), treatment sumps, cesspools of drainage systems, and nature reserves.
μ ATTENTION! Legislation and requirements vary from country to country. Always follow local legislation in force at any time.
÷ NOTE! It is the responsibility of the sprayer owner/operator to comply with all relevant legislation. HARDI cannot undertake any responsibilities for incorrect operation and use.
Filling of water
The tank should normally be filled 1/3 with water before adding chemicals. Always follow the instructions given on the chemical container!
± WARNING! If the sprayer is put aside with liquid in the main tank, all MANIFOLD valves must be closed.
5 - Operation

Cleaning
General info
In order to derive full benefit from the sprayer for many years the following service and maintenance program should be followed.
μ ATTENTION! Always read the individual paragraphs. Read instructions for service/maintenance jobs carefully before starting on the job. If any portion remains unclear or requires facilities which are not available, please for safety reasons leave the job to your HARDI dealer’s workshop.
μ ATTENTION! Clean sprayers are safe sprayers. Clean sprayers are ready for action. Clean sprayers cannot be damaged by pesticides and their solvents.
μ ATTENTION! Before any cleaning, please also see section on “Filling/washing location requirements” on page 38.
Guidelines1. 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, follow them closely.
2. Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods, etc. If in doubt, 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 cropping. Seepage or runoff of residue into streams, water courses, ditches, wells springs etc. must never happen. Use an appropriate washing place with hard, impenetrable surface (concrete) and drain to an appropriate tank (e.g. slurry tank) to avoid spot contamination and contamination of the underground water resources. Washings must be diluted and distributed over larger areas to ensure biological degrading. Applicable law must always be followed.
4. Cleaning starts with the calibration, as a well calibrated sprayer ensures the minimal amount of remaining spray liquid.
5. It is good practice to clean the sprayer immediately after use and thereby rendering the sprayer safe and ready for the 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 weather becomes suitable for spraying again. Unauthorized persons and animals must not have access to the sprayer under these circumstances.
7. 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.
μ ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the pressure to 1.5 bar when spraying diluted remaining liquid in the field just sprayed.
μ ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended.

4. Remove tank and suction filters and clean. Be careful 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. Don’t forget the tank roof. Rinse and operate all components and any equipment that have 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, e.g. washing soda or Triple ammonia.
7. Start the pump and operate all controls enabling the liquid to come into contact with all the components. Leave the dis- tribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short period. Check the label.
8. Drain the tank and let the pump run dry. Rinse inside of the tank, again letting the pump run dry.
9. Stop the pump. If the pesticides used have a tendency to block nozzles and filters, remove and clean them immediately.
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 aggressive, store the sprayer with the tank lid open.
μ ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the pressure to 1.5 bar (20 psi) when spraying diluted remaining liquid in the field just sprayed.
μ ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
μ ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended.

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 blockades do not occur whilst spraying.
• Long life of the pump. A blocked suction filter will result in pump cavitation. The main filter protecting sprayer compo- nents is the suction filter. Check it regularly.
Use of rinsing tank and rinsing nozzles (optional equipment)
The incorporated rinsing tank can be used for two different purposes.
μ ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
In-field diluting before cleaningIn-field diluting of remaining spray liquid residue in the spraying circuit, before cleaning the sprayer.
Rinsing the tank and liquid system:
1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of all nozzles.
2. Turn suction valve towards “Rinsing tank” and pressure valve towards “Spraying”. Set blue return valve to “To main tank”.
3. Engage and set the pump at approximately 300 r.p.m.
4. When 1/3 of the contents in the rinsing tank is used, turn suction valve towards “Main tank” and operate all valves on the pressure side of the system in the following order so that all hoses and components are rinsed:
• Turn the pressure valve towards “Filling of main tank” to activate ejector and open TurboFiller suction valve.
• Open TurboDeflector valve and close it again when clean water comes out of nozzles.
• Close TurboFiller lid and squeeze the Chemical Container Cleaning grip to clean this device.
• Open TurboFiller lid again and make sure that TurboFiller is empty.
• When empty, close the TurboFiller suction valve again. Take care that the External fast filling connection and the line are not contaminated with chemicals.
5. Turn the suction valve towards “Main tank” and the pressure valve towards “Spraying” and spray the liquid in the field just sprayed.
Cleaning of Main tank:
6. Turn the suction valve towards “Rinsing tank” and the pressure valve towards “Internal Tank Rinsing”. Remove the filling strainer to avoid any cleaning shadows behind it.
7. When another 1/6 of the contents in the rinsing tank is used, turn the suction valve towards “suction from Main tank”.
8. Turn pressure valve towards “Spraying” and spray the liquid in the field just sprayed.
9. Repeat point 6 - 8 one more time.
± WARNING! When critical chemicals (like sulphonyl urea) have been used or a cleaning detergent is recommended, do an extra cleaning:
10. Fill the rinse tank again.
11. Fill the main tank with 500 l clean water. See subject “Suction filling device” for filling procedure.
12. Add the cleaning detergent to the main tank by using the TurboFiller. Follow instructions on the label of the cleaning agent.
13. Clean the whole system again.
14. To get the best cleaning effect the Self-Cleaning Filter and the Suction Filter sieves should be washed with clean water.
15. Rinse the sprayer with clean water afterwards.
μ ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually with a brush afterwards, especially if crops sensitive to the chemical just sprayed are to be sprayed afterwards!

Off-season storage
Off-season storage program
To preserve the sprayer intact and to protect the components, carry out following off-season storage program.
Before storageWhen the spraying season is over, you should devote some extra time to the sprayer. If chemical residue is left over in the sprayer for longer periods, it may reduce the life of the individual components.
1. Clean the sprayer completely - inside and outside - as described under “Cleaning of the sprayer”. Make sure that all valves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so that no chemical residue is left in the sprayer.
2. Renew any damaged seals and repair any 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 comes out of all nozzles. Don’t forget to drain the rinsing tank also.
4. Pour approx. 50 litres (11 Imp.gal) anti-freeze mixture consisting of 1/3 automotive anti-freeze and 2/3 water into the tank.
5. Engage the pump and operate all valves and functions, operating unit, chemical inductor etc. allowing the anti-freeze mixture to be distributed around the entire circuit. Open the operating unit main ON/OFF valve and distribution valves so that 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 scratches or damage in the paint, if any, 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 RUSTILO or similar) on all metal parts. 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 corrosion.
12. Remove the control boxes and computer display from the tractor, and store them dry and clean (indoor). A non- condensing environment is recommended.
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 corrosion.
15. To protect against dust the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.
After storageAfter a storage period the sprayer should be prepared for the next season the following way:
1. Remove the cover.
2. Wipe off the grease from hydraulic ram piston rods.
3. Fit the pressure gauges again. Seal with Teflon tape.
4. Connect the sprayer to the tractor including hydraulics and electrics.
5. Check all hydraulic and electric functions.
6. Empty the tank for remaining anti-freeze.
7. Rinse the entire liquid circuit of the sprayer with clean water.
8. Fill with clean water and check all functions.

7 - Fault finding
Operational problems
General info
In cases where breakdowns have occurred, the same factors always seem to come into play:
1. Minor leaks (false air) 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 nozzles.
4. Foreign bodies stuck in the pump valves with the result that these cannot close tightly against the valve seat. This reduces pump efficiency.
5. Poorly reassembled pumps, especially diaphragm covers, will allow the pump to suck air resulting in reduced or no capacity.
6. Hydraulic components that are contaminated with dirt result in rapid wear to the hydraulic system.
7. Poor power supply causes failures and misbehavior to the electric system.
Therefore ALWAYS check1. 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.
7. Check tractor batteries and keep connectors clean.
