1. Always STOP ENGINE before attaching the transmis-sion shaft to tractor P.T.O. - most tractor P.T.O. shaftscan be rotated by hand to facilitate spline alignment,when engine is stopped.

2. When attaching the shaft, make sure that the snaplock is FULLY ENGAGED - push and pull shaft until itlocks.

WARNING! ROTATING TRANSMISSIONSHAFTS WITHOUT PROTECTION GUARDSARE FATAL.

3. Always keep protection guards and chains intact andmake sure that it covers all rotating parts, includingCV-joints at each end of the shaft. Do not use withoutprotection guard.

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

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

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

7. Always STOP ENGINE and remove the ignition keybefore carrying out maintenance or repairs to thetransmission shaft or implement.

InstallaInstallaInstallaInstallaInstallation oftion oftion oftion oftion of tr tr tr tr transmission shaftansmission shaftansmission shaftansmission shaftansmission shaftFirst installation of the transmission shaft is done in thefollowing way:

1. Attach sprayer to tractor and set sprayer height in theposition with shortest distance between the tractorand sprayer pump P.T.O. shafts.

2. Stop engine and remove ignition key.3. If transmission shaft must be shortened, the shaft is

pulled apart.

Fit the two shaft parts at tractor and sprayer pumpand measure how much it is necessary to shorten theshaft.

Mark the protection guards.

NOTE! The shaft must always have a minimum overlap.The size of this overlap depends on the pump model:

Pump with 6 splines/540 r.p.m.The shaft must always have an overlap (A) of minimum1/3 of the length.

Pump with 21 splines/1000 r.p.m.The shaft must always have an overlap (A) of minimum2/3 of the length.

4. The two parts are shortened equally. Use a saw, andfile the profiles afterwards to remove burrs.

5. Grease the profiles and assemble male and femaleparts again.

6. Fit the shaft to tractor P.T.O. and sprayer pump shaft.

NOTE! Female part marked with a tractor towardstractor!

Ball check valve (8) should normally be open, but can beclosed in situations where return flow is to be avoided.

NOTE! If ball check valve is closed the self-cleaningfilter is inoperative!

Choice of restrictorIt is important to have a large flow through the filter. Thisis achieved by choosing the restrictor size in relation tothe liquid consumption of the spray boom.

4 restrictors are supplied. Usethe green one (largest orifice Afirst).

Hose N is removed from the filter.Be careful not to loose the seal.The restrictor is placed in thehose and the hose is mountedagain.

If the required working pressurecannot be obtained, the restrictoris too large. Choose a smallerrestrictor. Start with a black one,then a white and finally a red one.

When cleaning the filter remove hose N and the hose atthe safety valve and check there are no residues.

Maintenance

Maintenance - rMaintenance - rMaintenance - rMaintenance - rMaintenance - rules ofules ofules ofules ofules of thumb thumb thumb thumb thumbIn order to derive full benefit from the sprayer for manyyears the following service and maintenance programshould be followed.

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

Cleaning the sprCleaning the sprCleaning the sprCleaning the sprCleaning the spraaaaayyyyyerererererGuidelines1. Read the whole chemical label. Take note of any

particular instructions regarding recommendedprotective clothing, deactivating agents, etc. Read thedetergent and deactivating agent labels. If cleaningprocedures are given, follow them closely.

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

3. Pesticide washings can usually be sprayed out on asoakaway. This is an area of ground that is not usedfor cropping. You must avoid seepage or runoff ofresidue into streams, water courses, ditches, wells,springs, etc. The washings from the cleaning areamust not enter sewers. Drainage must lead to anapproved soakaway.

4. Cleaning starts with the calibration, as a well cali-brated sprayer will ensure the minimal amount ofremaining spray liquid.

5. It is good practice to clean the sprayer immediatelyafter use and thereby rendering the sprayer safe andready for the next pesticide application. This alsoprolongs the life of the components.

6. It is sometimes necessary to leave spray liquid in thetank for short periods, e.g. overnight, or until theweather becomes suitable for spraying again. Unau-thorised persons and animals must not have accessto the sprayer under these circumstances.

7. If the product applied is corrosive, it is recommendedto coat all metal parts of the sprayer before and afteruse with a suitable rust inhibitor.

Remember:

Clean sprayers are safe sprayers.Clean sprayers are ready for action.Clean sprayers cannot be damaged by pesti-cides and their solvents.

Cleaning the tank1. Dilute remaining spray liquid in the tank with at least

10 parts of water and spray the liquid out in the fieldyou have just sprayed.

NOTE! It is advisable to increase the forward speed(double if possible) and reduce the pressure to 1.5bar (20 psi).

2. Select and use the appropriate protective clothing.Select detergent suitable for cleaning and suitabledeactivating agents if necessary.

3. Rinse and clean sprayer and tractor externally. Usedetergent if necessary.

4. Remove tank and suction filters and clean. Be carefulnot 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 allcomponents and any equipment that has been incontact with the chemical.

Before opening the distribution valves and sprayingthe liquid out, decide whether this should be done inthe field again or on the soakaway.

6. After spraying the liquid out, stop the pump and fill atleast 1/5 of the tank with clean water. Note that somechemicals require the tank to be completely filled.Add appropriate detergent and/or deactivating agent,e.g. washing soda or Triple ammonia.

NOTE! If a cleaning procedure is given on the chemi-cal label, follow it closely.

7. Start the pump and operate all controls enabling theliquid 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 thetank for a short period. Check the label. The Self-Cleaning Filter can be flushed by removing the by-pass hose from the bottom of the filter. Stop the pumpand remove the hose. Start the pump for a fewseconds to flush filter. Be careful not to lose therestrictor nozzle.

8. Drain the tank and let the pump run dry. Rinse insideof the 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 cleanthem immediately. Also check for sediment on thepressure side of the safety valve for the Self-CleaningFilter.

26 GB 12 01 MA

Maintenance

10. Replace all the filters and nozzles and store thesprayer. If, from previous experiences, it is notedthat the solvents in the pesticide are particularlyaggressive, store the sprayer with the tank lid open.

NOTE! If the sprayer is cleaned with a high pressurecleaner lubrication of the entire machine is recom-mended.

Cleaning and maintenance ofCleaning and maintenance ofCleaning and maintenance ofCleaning and maintenance ofCleaning and maintenance of f f f f filterilterilterilteriltersssssClean filters ensure:

• Sprayer components such as valves, diaphragms andoperating unit are not hindered or damaged duringoperation.

• Nozzle blockages do not occur whilst spraying.

• Long life of the pump. A blocked suction filter willresult in pump cavitation.

The main filter protecting sprayer components is thesuction filter at the top of the tank. Check it regularly.

Nozzle tubes and fittingsPoor seals are usually caused by:

• Missing O-rings or gaskets• Damaged or incorrectly seated O-rings• Dry or deformed O-rings or gaskets• Foreign bodies

In case of leaks:

DO NOT overtighten. Disas-semble, check condition andposition of O-ring or gasket.Clean, lubricate and reassem-ble.

The O-ring must be lubricatedALL THE WAY ROUND beforefitting on to the nozzle tube. Usenon-mineral lubricant.

For RADIAL connections only hand-tighten them.

For AXIAL connections, a little mechanical leverage maybe used.

If chemical residue is left over in the sprayer for longerperiods, it can reduce the life of the individual compo-nents.

OfOfOfOfOff-season storf-season storf-season storf-season storf-season storaaaaaggggge pre pre pre pre progogogogogrrrrramamamamamTo preserve the sprayer intact and to protect the compo-nents, carry out following off-season storage program.

1. Clean the sprayer completely - inside and outside - asdescribed under “Cleaning of the sprayer”. Make surethat all valves, hoses and auxiliary equipment havebeen cleaned with detergent and flushed with cleanwater afterwards, so no chemical residue is left in thesprayer.

2. Renew possible damaged seals and repair possibleleaks.

3. Empty the sprayer completely and let the pump workfor a few minutes. Operate all valves and handles todrain as much water off the spraying circuit as possi-ble. Let the pump run until air is coming out of allnozzles. Remember to drain the rinsing tank also.

4. Pour appr. 50 litre (11 Imp.gal) anti-freeze mixtureconsisting of 1/3 automotive anti-freeze and 2/3 waterinto the tank.

5. Engage the pump and operate all valves and func-tions on the MANIFOLD, operating unit, FILLER etc.allowing the anti-freeze mixture to be distributedaround the entire circuit. Open the operating unit mainon/off valve and distribution valves so the anti-freezeis 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 lubri-cating scheme - regardless of intervals stated.

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

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

9. Apply a thin layer of anti-corrosion oil (e.g. SHELLENSIS FLUID, CASTROL RUSTILLO or similar) on allmetal parts. Avoid oil on rubber parts, hoses.

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

11. All electric plugs and sockets are to be stored in adry plastic bag to protect them against damp, dirtand corrosion.

12. Remove the control boxes and the HARDI PILOTcontrol box + display from the tractor, and store themdry and clean (in-house).

13. Wipe hydraulic snap-couplers clean and fit the dustcaps.

14. Apply grease on all hydraulic ram piston rods whichare not fully retracted in the barrel to protect againstcorrosion.

15. To protect against dust the sprayer can be coveredby a tarpaulin. Ensure ventilation to prevent conden-sation.

Fault finding

OperOperOperOperOperaaaaational prtional prtional prtional prtional proboboboboblemslemslemslemslemsIn 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. 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.

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.
