The HARDI sprayer is for the application of crop protection chemicals and liquid fertilisers. The equipment must only beused for this purpose. It is not allowable to use the sprayer for other purposes. If no local law demands that the operatormust be certified to use spray equipment, it is strongly recommended to be trained in correct plant protection and insafe handling of plant protection chemicals to avoid unnecessary risk for persons and the environment when doing yourspray job.
Very strong and compact frame which also has a strong chemical and weather resistant electrostatic lacquer coat.Screws, nuts, etc. have been DELTA-MAGNI treated to be resistant to corrosion.
The main tank made of impact-proof, UV-resistant and chemical resistant polyethylene, has a purposeful design with nosharp corners for easy cleaning. Nominal contents 2200, 2800, 3200 or 4200 l. A large, easy to read tank contents indicatoris placed beside the platforn and is visible from the tractor cabin. The filling hole is placed so it can be accessed from theplatform. This ensures an easy access for the filling of sprays, cleaning of the tank, etc. The sprayer can also be equippedwith a rinsing tank, a clean water tank as optional.

The functions of the spray circuit are operated via the centrally situa-ted SmartValve MANIFOLD with colour coded plates and pictorialsymbols for easy operation.
The modular SmartValve system facilitates the addition of optionalextras on both pressure SmartValve (B) and suction SmartValve (C)and a third valve (A) for agitation and for rinsing nozzle (optionalequipment). Furthermore the suction manifold can be fitted with areturn valve which ensures better draining of the sprayer before cle-aning.
A quick reference (D) can be fitted to manifold plate, for a quickoverview of the functions.

ATTENTION! Only the functions in use should be open - always close remaining valves.
ATTENTION! If a MANIFOLD valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be ser-viced. Please see the section ‘Maintenance’ for further information.
To Self-Cleaning Filter/operating unit
On the Smart Valve a function is activated/opened by turning thehandle towards the desired function. If the lever points at an unusedposition, then the Smart Valve will be closed.
From main tank (suction filter)
On the Smart Valve a function is activated/opened by turning thehandle towards the desired function. If the lever points at an unusedposition, then the Smart Valve will be closed.
The valve is marked with an arrow on the green disc that indicates the amount of liquid that passes through the valve. Ifhandle is turned to a position near the tip of the arrow, then only a small amount of liquid is allowed to pass the valve.Otherwise, if handle is turned to a position in the wide end of the arrow, it means that a larger amount is passing thevalve. This gives the posibility to continously adjust how large amount of fluid from the pump is used for agitation in thetank and for spraying.
Examples on handle positions at different agitation quantities:
1. Handle is in the “widest end of arrow” position (full open).Agitation quantity is 100%.

One or more MANIFOLD valve(s) can be electrically operated via a control box in the tractor cabin. These can only beoperated manually if the power to the valve motor is disconnected.
With the self-cleaning filter the impurities that exist in the spray liq-uid will by-pass the filter and be recirculated back to the tank via thereturn flow.

The system is based on EVC - Electrical Valve Control. The on/off is linked to the section valves, which is resulting in a veryquick response to on/off. The operating unit is constructed of modules and is electrically controlled via a remote controlbox.
The built-in HARDI-MATIC ensures a constant volume per hectare of the liquid (l/ha) at varying forward speed within thesame gear when the number of P.T.O. revolutions are between 300-600 r.p.m. (pump 540 r.p.m) or 650-1100 r.p.m. (pump1000 r.p.m.).
EVC - Electrical Valve 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. The unit is fitwith build-in HARDI MATIC.

WARNING! Always drive the SELF TRACK very carefully on public roads, and be aware of the sprayer’s behaviour.Slow down before turning, to avoid the vehicle from tipping over.
The SELF TRACK is always in tracking mode.
The SELF TRACK drawbar will always articulate when the tractor is turning and follow the tractor rear wheels.
The SELF TRACK drawbar is hydraulically damped to obtain stable trailing.
Please see seperate instruction book for track calibration and operation.
AUTO TRACK
A trailer with articulating drawbar (TRACKER) behaves differentlythan a normal trailer. In tracking position the vehicle centre of gravi-ty is displaced further more compared to the vehicle centre line of anormal trailer.
Compared to a conventional trailer a TRACKER has decreased stabili-ty when turning, especially when turning 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 (B), when thesprayer is articulated.
4. Be careful when turning on uneven ground.
5. Set the track gauge (A) as wide as possible.
6. The proper function of the hydraulic damping is essential toobtain good stability.
7. For SELF TRACK: Keep stabiliser chains on the tractor’s liftarmstight.
8. For safety reasons, the following limitations are set for TRACKERS(with unfolded booms):
Max. speed by turning is 4 km/h (2.5 m.p.h.).
Max. ground inclination (B) by turning is 8°.
Min. recommended track gauge (A) is 1800 mm.
STEER TRACK are operated by the tractors hydraulic levers. This isused when turning or as track correction when driving on slopes.

Although the sprayer has been applied with a strong and protective surface treatment on steel parts, bolts etc. in the fac-tory, it is recommended to apply a film of anticorrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) on all metalparts in order to avoid chemicals and fertilisers discoloring the enamel. If this is done before the sprayer is put into opera-tion for the first time, it will always be easy to clean the sprayer and keep the enamel clean for many years. This treatmentshould be carried out every time the protection film is washed off
Support leg
For the unloading of the sprayer, you need a crane. When unloadingwith a crane please observe the lifting points as shown on the pictu-re, and make sure that the straps or belts used for lifting are strongenough.
The support leg is stored in the bracket on the sprayer’s right sidewhen the sprayer is attached to the tractor. To remove the supportleg: Lift the leg, remove the linch pin and pull out the support leg.The support leg can then be mounted to the drawbar extensionand secured by linch pin.

WARNING! Always be sure to fully extract or retract theopen/closed center selection valve (1). Failure to do so canresult in damages to vital pump parts.
WARNING! It is of essential importance that connectors onsensing line are kept totally clean. Failure to do so can resultin impurities entering the pump and thereby cause damagesto vital pump parts.
The open centre hydraulics block is needed if the tractor uses opencentre hydraulics and/or if load sensing will be used.
The valve (1) on the side of the block is factory set for open centrehydraulics, but if closed centre hydraulics will be used in combina-tion with load sensing, then screw in the valve.
Certain tractor models are able to use Load Sensing without con-necting an external sensing line. But if optimal sensing control pres-sure cannot be obtained, an external sensing line needs to bemounted (3). Please consult your tractor dealer for correct setup andcorrect connection.
Before operating the hydraulics, the valve should be adjusted accor-ding to the specific tractor model. If you have doubt about whichtype of hydraulic system your tractor is equipped with, please con-sult your tractor dealer.

ATTENTION! Always use both bolts to assemble the lock. Thesetting must be identical on both sides.
ATTENTION! The rear settings must correspond to the frontsettings so the boom is resting on the front as well as rearbrackets.
The transport brackets and transport lock can be set in different positions. Thereby it is possible to obtain different trans-port heights and suitable clearance above various tractor cabins. When changing the setting of the transport brackets itis done as a combination of adjusting the transport brackets themselves and adjusting the transport locks. Always choo-se a transport height as low as possible.
For LPY models the wire should be adjusted simultaneously with thetransport lock. A combination of adjustments described in the follo-wing part form each transport position. This includes adjustment ofthe tranport lock and the wire mounting.
To change position of the wire:
1. Loosen the nut and remove the bolt, which holds the wire (A) tothe mounting (B).
2. Place the wire (A) in correct position (please refer to chart) andreassemble.
When the boom is unfolded: Inspect the gap between the bolt (A)and the frame. Correct position = 1 mm gap.
If necessary, adjust the position of bolt (A).
WARNING! The max. transport height must never exceed 4.0m (13.1 ft.). Always measure the actual total height and choo-se settings not exceeding 4.0 m.

ATTENTION! The system must not be pressurized duringadjustment.
DANGER! Test of the hydraulic system should be done verycautiously. There may be air trapped in the system which cancause violent movements of the boom.
The purpose of this adjustment is to align the 4 steering arms (A) tolevel position. Adjustment of the pendulum device needs to be car-ried out before putting the sprayer into operation for the first time.Subsequent adjustment will be required very seldom.
Perform adjustments with the boom unfolded.
1. Support the pendulum with e.g. a crane.
2. Remove the bolt in the bottom end of the spring arrangementand the big nut at the upper end of arrangement.
3. Lower the pendulum until spring arrangement clears the pendu-lum.
4. Remove the spring arrangement.
5. Fix the ends of spring arrangement. Grasp around the spring androtate the whole spring arrangement to regulate the length of it.
Clockwise rotation: The spring arrangement becomes longer andthe steering arms are moved downwards.
Counterclockwise rotation: The spring arrangement becomes shor-ter and the steering arms are moved upwards.
Use a level to inspect the alignment to make sure the 4 steeringarms are level. When correct position is obtained:
1. Refit the spring arrangement and tighten the big nut at the upperend of arrangement.
2. Extra check that the spring arrangement is correctly refitted andthen release support from pendulum.
DANGER! Hydraulic leaks: Never use your fingers to locate aleakage in any part of the hydraulic system. Due to high pres-sure, hydraulic oil may penetrate the skin.
Adjustable restrictors for the regulation of boom folding and unfol-ding speed, are located on the hydraulic distribution block (fitted atthe boom centre frame). It is important to adjust the valves to ensu-re that the boom operates smoothly.
1. Adjust the 4 screws (A). They are screwed the whole way inclockwise, and then 1 turn back. The system is now basically adju-sted.
2. Unfold and fold the boom several times in order to heat the oiland remove air from the system.
3. Adjust the screws (A) until the individual rams run with the speedwanted (clockwise = less speed).

The pendulum effect can be adjusted to match the local topograp-hy. For this purpose, the 2 bottom steering arms can be locked in 3different positions. Always use the same position for both bottomsteering arms, and perform adjustments with the boom unfolded.
POSITION 1: The boom is free and will optimize suspension towardshorizontal. Use position 1 when spraying flat country.
POSITION 2: The boom follows the movements of the trailer to someextent. Use position 2 when spraying hilly land.
POSITION 3: The boom follows the movements of the trailer to ahigh extent. Use position 3 when spraying very hilly land.
Pendulum effect adjustment
When driving on slopes, the boom can be slanted in order to matchthe local topography.
At delivery the boom is locked in pos. 2 (neutral) which is usedwhen driving on horizontal grounds.
The slanting angle is adjusted as follows and with the boom unfol-ded:
1. Remove the linch pin (A).
2. Reset the position of the cylinder according to the holes (1, 2 or3).
3. Secure linch pin (A) again.
Minor adjustments of the boom in order to adjust it vertically can bedone by adjusting the position of nut (B).

ATTENTION! The distance must be uniform on both upperand lower frame part, and the distance should be in the span175-185 mm. Measure the distances to control the uniformity!
The lift frame and the pendulum must be parallel positioned. Ifnecessary, the length of the 4 steering arms can be adjusted toobtain parallel setting.
Adjustment of each steering arm is performed as follows:
1. Loosen nuts (A).
2. Place a suitable tool (e.g. a screwdriver) in the hole (B) in the turnbuckle, and use the tool to rotate the turn buckle.
Clockwise rotation: The turnbuckle becomes shorter and the distan-ce between centre section and lift/trailer decreases.
Counterclockwise rotation: The turnbuckle becomes longer and thedistance between centre section and lift/trailer increases.
3. When correct setting has been obtained, tighten nuts (A) on theturnbuckle again.

ATTENTION! To ensure safe engagement and to avoid dama-ges to the parking brake use rope with an ultimate stress bet-ween 690 N (155 lb.) and 785 N (176 lb.).
WARNING! Do not connect the brakes directly to the tractorhydraulics without the brake valve. The trailer brake powercannot be controlled, and braking will therefore be hazar-dous.
WARNING! Max. oil pressure is 150 bar (2175 p.s.i.) in the brakeline.
Relieve parking brake before driving.
The parking brake is located at the right side of the sprayer in theclean zone.
The parking brake lever has two function modes, which are determi-ned by the small pawl control clip (A). To change between the twomodes, turn the clip.
Pos. 1: The pawl control clip must rest against the pawl.
Pos. 2: The pawl control clip must point away from the pawl.
To disengage the parking brake:
1. Set pawl control clip in pos. 1.
2. Pull the lever a little forward to release the pawl from the ratchetand then push the lever fully backwards.
To engage the parking brake:
1. Set pawl control clip in pos. 2.
2. Pull the lever firmly forwards until parking brake is fully engaged.
Emergency brake
1. Set pawl clip in pos. 2.
2. Attach the rope from the hole in top of the handbrake lever (B) toe.g. the tractor top link attaching point. If the sprayer is accidentallyunhooked during transport the rope will apply the parking brakebefore the rope breaks.
This requires a special trailer brake valve attached to the tractor hyd-raulic and brake system. Connect the snap coupler to the tractorbrake outlet. When the tractor brakes are applied, the trailer brakeswill work proportionally to the tractor brakes, and ensure safe andeffective braking.

Relieve parking brake before driving.
This system requires a tractor with compressor and air brake systemwith out-let(s) for trailer brakes.
If the air hose(s) are disconnected with air in the brake air tank, con-trol pressure will be dumped and the brakes will engage fully. If thesprayer must be moved with air in the tank and without the airhose(s) connected to the tractor, the load apportioning valve mustbe set at “relieved” to disengage the brakes. Remember to reset thehandle to brake position again afterwards. When parking the sprayer,always engage the parking brake, as the air brakes will only be enga-ged as long as there is air in the tank! Cover the couplings with thedust flaps when hoses are disconnected.

ATTENTION! Always read the individual paragraphs. Read instructions for service/maintenance jobs carefully beforestarting on the job. If any portion remains unclear or requires facilities which are not available, then for safety rea-sons 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, follow themclosely.
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 cropping.You must avoid seepage or runoff of residue into streams, water courses, ditches, wells, springs, etc. The washings fromthe 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 spray liq-uid.
5. It is good practice to clean the sprayer immediately after use and thereby rendering the sprayer safe and ready for thenext 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 beco-mes suitable for spraying again. Unauthorised persons and animals must not have access to the sprayer under these circ-umstances.
7. If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after use with asuitable rust inhibitor.
In order to derive full benefit from the sprayer for many years the following service and maintenance program should befollowed.

ATTENTION! It is advisable to increase the forward speed (double if possible) and reduce the pressure to 1.5 bar (20psi) when spraying diluted remaining liquid in the field just sprayed.
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
ATTENTION! If the sprayer is cleaned with a high pressure cleaner lubrication of the entire machine is recommen-ded.
1. Dilute remaining spray liquid in the tank with at least 10 parts of water and spray the liquid out in the field you havejust sprayed.
2. Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivatingagents if necessary.
3. Rinse and clean sprayer and tractor externally. Use detergent if necessary.
4. Remove tank and suction filters and clean. Be careful not to damage the mesh. Replace suction filter top. Replace filterswhen 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 andany equipment that has been in contact with the chemical. Before opening the distribution valves and spraying the liq-uid 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 chemicalsrequire the tank to be completely filled. Add appropriate detergent and/or deactivating agent, e.g. washing soda or Tripleammonia.
7. Start the pump and operate all controls enabling the liquid to come in 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. Checkthe label. The Cyclone filter can be flushed by engaging the lever in the buttom to flush position. Stop the pump andremove the hose. Start the pump for a few seconds to flush filter. Be careful not to lose the restrictor nozzle.
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 immediate-ly.
10. Replace all the filters and nozzles and store the sprayer. If, from previous experiences, it is noted that the solvents inthe pesticide are particularly aggressive, store the sprayer with the tank lid open.
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 compo-nents is the suction filter. Check it regularly.

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 agitation valve (no agitation) and spray till air comes out of all nozz-les.
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 valves onthe pressure side of the system in the following order, so all hoses and components are rinsed: Open HARDI FILLER bot-tom valve, engange the hopper rinsing device and close it again when clean water comes out. Close HARDI FILLER lidand squeeze the Chemical Container Cleaning handle to clean this device. Open HARDI FILLER lid again and assure thatthe hopper is empty. When empty then close the HARDI FILLER bottom valve again.
5. Turn the suction SmartValve towards “Main tank” and pressure SmartValve towards “Spraying” and spray liquid in thefield 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 1/3 of content in rinsing tank are used, then turn suction SmartValve towards “suction from Main tank”.
8. Turn pressure SmartValve towards “Spraying” and spray liquid in the field you have just sprayed.
9. Repeat point 6 - 8 one more time.
B. Rinsing the pump, operating unit, spray lines, etc. in case of stop in spraying before main tank is empty (e.g. beginningrain 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 residues in the tank should be diluted immediately in the relationship 1:10 with water and afterwards be sprayed tothe crop just sprayed with increased driving speed. In addition the rinsing tank is to be used, with this can also pump, lin-kage and armature separately be rinsed. It is to be made certain however that the liquid in the lines in unchanged con-centration is sprayed out, so there should be an untreated patch available.
The drain valve is located and operated from the platform just besi-de the main tank lid. Pull the string to open the drain valve. Thevalve is spring-loaded, but can be kept open by pulling the stringupwards in the V-shaped slit. To release, pull the string downwardand the valve will close automatically.
If draining residues, e.g. liquid fertilizer into a reservoir, a snap-coup-ler with hose can rapidly be connected to the drain valve and theliquid safely drained.

DANGER! Non observance of mounting instructions will result in the bad seating of the tyre on the rim and couldcause 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 brazed rimis not allowed!
WARNING! Plug the hose. If this is neglected, the pressure gauge may be damaged.
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 be repai-red 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 equivalent anti-corrosion lubricant. Never use petroleum based greases and oils because they may damage the tyre. Using the appro-priate 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 wire tearcan 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 any ofthe beads do not seat correctly, deflate the assembly and re-centre the beads before starting inflation of the tyre. If thebeads are seated correctly on the rim at 100-130 kPa inflate the tyre to a maximum of 250 kPa (36 p.s.i.) until they seatperfectly 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.
The following venting procedure requires a special venting kit, HARDI ref. no. 730725.
1. Place the trailer on the support leg so that the yoke goes free from the tractor and the rams can work freely.
2. Relieve the pressure in the expansion tank and remove the hydraulic hose.
3. Fit the two test hoses in the pressure gauge outlets on the rams (at the rear of the track system).
4. Move the track system from one side to the other approx. 10 times (full swing).
5. Loosen the plug very carefully in order to leak the air out of the system.
6. Fit the hydraulic hose on the expansion tank.
7. Remove the level plug and using the tractor hydraulics, cautiously fill oil in the expansion tank until it reaches the levelplug.
8. Fit the level plug and fill the expansion tank to an air pressure of 5 bar.
9. Fit the 0-400 bar pressure gauge on the pressure gauge outlet at the ram. Adjust the excess-pressure valve to approx.40 bar.
On flat ground it is possible to work with a lower opening pressure. This gives a more sensible reaction but it also resultsin the fact that the trailer can swing when driving on hilly ground and when swinging at high speed.

When the spraying season is over, you should devote some extra time to the sprayer. If chemical residue is left over in thesprayer for longer periods, it can reduce the life of the individual components. To preserve the sprayer intact and to pro-tect 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 that all val-ves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so nochemical 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 the tank.
5. Engage the pump and operate all valves and functions on the MANIFOLD, operating unit, chemical inductor etc. allo-wing the anti-freeze mixture to be distributed around the entire circuit. Open the operating unit main on/off valve anddistribution 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 metal parts. Avoidoil 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 (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 corrosion.
15. Chock up the wheels, to prevent moisture damage and deformation of the tyres. Tyre blacking can be applied to thetyre 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.
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 the pressure gauges again. Seal with Teflon tape.
5. Connect the sprayer to the tractor including hydraulics and electric’s.
6. Check all hydraulic and electric functions.
7. Empty the tank for remaining anti-freeze.
8. Rinse the entire liquid circuit on the sprayer with clean water.
9. Fill with clean water and check all functions.
10. Check function of brakes. Please note that brake power will be reduced until the rust are worn off the drums. Alwaysbrake lightly until the drums are clean.

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 nozzles.
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.
