Roadworthiness
When driving on public roads and in other areas, where the highway code applies, or in areas with special rules and regulations for marking and lights on implements, you should observe these and equip implements accordingly.
Sprayer Use
The HARDI sprayer is for the application of crop protection chemicals and liquid fertilizers. The equipment must only be used for this purpose. It is not allowed to use the sprayer for any other purposes. If no local law demands that the operator must be certified to use spray equipment, it is strongly recommended to be trained in correct plant protection and in safe handling of plant protection chemicals to prevent unnecessary risk for persons and the environment, when carrying out your spray job.
Frame
Very strong and compact steel frame with a strong chemically resistant and weatherproof electrostatic lacquer coat. Screws and bolts etc. have been Delta/Magni treated to be resistant to corrosion.
Identification Plates
CE identification plate fitted on the frame indicates producer name, identification no., make, model, type, production year, tank capacity and tare mass for the sprayer.
This plate is located on the front side of the sprayer.
Ta nk s
The tanks are made of impact-proof polyethylene, resistant to UV radiation and chemicals. The main tank has a purposeful design with no sharp corners for easy cleaning. The filling hole is placed so it can be accessed from the platform. This ensures an easy access for the filling of sprays, cleaning of the tank etc. The sprayer may also be equipped with two rinsing tanks and a clean water tank.
Nominal tank contents are 1200, 1500 or 1800 litres.

Liquid system
Pump
Diaphragm pump with 3 diaphragms, model 1303 or diaphragm pump with 6 diaphragms, model 363 or 364 or 464.
Standard = 540 rpm (6 splines shaft). The design of the diaphragm pump is simple, with easily accessible diaphragms and valves, which ensure that liquid does not contact the vital parts of the pump.
Pump model 363 is shown on the picture.
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. If the handle is turned to a label-free position (unused function), the valve is closed. The valves are:
A. Agitation Valve
B. Pressure Valve
C. Suction Valve
D. External Filling Valve (optional equipment)
A - Pressure valve
With this valve you can select where to direct pressurized liquid.
B - Agitation valve
With this valve you can select between agitation in the tank or tank cleaning using the rinsing nozzle.

C - Suction valve
With this valve you can select suction from main tank (for spraying) or from rinsing tank.
D - External Filling Device valve (optional)
This valve is used, when filling from an external tank or reservoir.
Activating the 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.
EVC Control Unit
The system is based on EVC - Electrical Valve Control. The ON/OFF is linked to the section valves (one valve for each spray boom section), which results in a quick response to ON/OFF. The operating unit is of modular design, and it is electrically controlled by a remote control box.
The section valves are fitted with a constant pressure device and a pressure drop line.
These features allows the operator to shut off individual boom sections.
The unit has a built-in HARDI-MATIC system. This system ensures a constant liquid volume per hectare (l/ha) when driving forward at varying speed within the same gear, as long as the number of PTO revolutions are kept between 300-600 rpm.

Clean Water Tank
The water in this tank is for hand washing, for cleaning of clogged nozzles etc. Only fill this tank with clean water from the well.
The clean water tank is placed on the sprayer’s left side, right behind the manifold valves.
Capacity: approximately 15 litres.
±
WARNING! Although the clean water tank is only filled with clean water, this water must NOT be used for drinking.
Filters
A suction filter is fitted at the top of the tank. It is indicated with a red hose tail.In-line pressure filters can be fitted at each boom section as an option(J). However, it is standard equipment on this sprayer.
Nozzle filters are fitted at each nozzle.
All filters should always be in use and their function should be checked regularly. Pay attention to the correct combination of filter and mesh size. For more, see “Technical Specifications” in this book.
Self-Cleaning Filter
With the self-cleaning filter, the impurities that exist in the spray liquid will be filtered out and returned to the tank via the return flow.

BoomPrime
BoomPrime is a low pressure circulation system, which primes the spray boom tubes prior to spraying, ensuring a homogenous fluid in the boom tubes and in the main tank. Below the illustration shows the BoomPrime system for the boom. Components are explained in the diagrams for the liquid systems.
The BoomPrime system is attached to each end of a boom section (A).
The boom spray sections are fed into the middle of each section (B).
Liquid for BoomPrime is taken through a bypass valve (D) just before the flowmeter. This valve operates in opposite phase:
When priming, the direction of liquid flow will be reversed. The liquid will be fed into the nozzle tubes from each end, and they will then return any water back to the main tank through the EFC section valves return line (C).
The BoomPrime pressure is adjusted by the handle on the control valve (E), which comprises a pressure gauge.
For adjustment, see the section “BoomPrime Adjustment”.

Dilution Kit (optional)
The dilution kit is a built-in system consisting of the two valves (no. 25 and 26 below) added to the liquid system, enabling the liquid to be redirected from the rinsing tanks into the main tank and piping to dilute the spray liquid residues.
The dilution kit will ease diluting of chemicals in main tank or boom piping done from the drivers seat, while driving in the field. This can be useful when interrupting a spray job, e.g. because of rain or before the tank has to be refilled at the farm. The dilution kit has two functions which are selected from the optional function switch on the Spray Box in the tractor.
Tank dilution: Dilute boom piping and the main tank at the same time.
Boom dilution: Dilute the boom piping only.

Spray 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, 24, 27 and 28 m working width. All booms are provided with spring loaded breakaway.
For 3-folded booms, the terminology is as follows:
A - Centre section
C - Middle section
D - Outer section
E - Breakaway section
3 - Description
27
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. Both when calibrating and spraying, the pressure must be adjusted according to the readings of this pressure gauge.
Footboard
The footboard gives access to the main tank lid. It ensures easy access for filling of sprays, cleaning of tank, etc.
Safety Locker
The safety locker is 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 and contaminated equipment.
±
WARNING! Although this locker is meant for the storing of non­contaminated items, it must never be used for the storing of food, beverage or other items meant for human consumption.

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 anti-corrosion oil (e.g. CASTROL RUSTILO or SHELL ENSIS FLUID) on all metal parts in order to avoid chemicals and fertilizers discolouring 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!

Checking the Suitability of the Tractor
General Info
Before connecting the sprayer to your tractor, you must check the suitability of the tractor. Only connect a tractor which is suitable for the purpose.
Perform a brake test to check whether the tractor achieves the required braking rate with the sprayer connected.
DANGER! An unsuitable tractor, or improper use of the tractor, causes a risk of:
insufficient tractor stability, steering and braking power
severe or fatal injuries
the sprayer being damaged during operation
Requirements for the suitability of a tractor are, in particular:
Permissible total weight
Permissible approved axle loads
Load capacity of the tyres fitted
Approved front weights must be sufficient
You can find this data on the rating plate of the tractor or in the tractor’s instruction manual or documentation. Ask your tractor dealer if in doubt.
The front axle of the tractor must always be subjected to at least 20% of the total weight of the vehicle.
The tractor must achieve the braking rate specified by the tractor manufacturer, even with the sprayer connected.
Calculating Actual Weights and Loads
The permissible total tractor weight, specified in the tractor documentation, must be greater than the sum of the:
Tractor’s tare weight
Tractor’s ballast and weights
Sprayer’s total weight
4 - Sprayer Setup

Transmission shaft
Operator Safety
1. Always STOP THE ENGINE before attaching the transmission shaft to the tractor power take-off (PTO) - most tractor PTO 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 stan d on the tr ansmissi on sha ft, wh en it i s rot ating - keep your safet y distance at 1.5 m eter. Also NEVER cross over a rotating PTO shaft to reach the other side of the sprayer.
5. Prevent protection guards from rotating by attaching the chains allowing sufficient slack for turns.
6. Make sure that protection guards around the tractor PTO and the implement shaft are intact.
7. Always STOP THE ENGINE and remove the ignition key, before carrying out maintenance or repairs to the transmission
shaft or implement.
DANGER! A ROTATING TRANSMISSION SHAFT WITHOUT PROTECTION GUARDS IS FATAL!
PTO Installation
DANGER! As PTO shafts are dangerous in operation, always read the manufacturer’s instruction book before applying any changes to the transmission shaft!
First installation of the transmission shaft is done in the following way:
1. Attach the sprayer to the tractor and set the sprayer height in the position with the shortest distance between the tractor and the sprayer pump PTO shafts.
2. Stop the engine and remove the ignition key.
3. If the transmission shaft needs to be shortened, pull the shaft
apart. Fit the two shaft parts to the tractor and the sprayer pump and measure how much the shaft needs to be shortened. Also mark the protection guards with the same length to be shortened.
±
WARNING! Only shorten the shaft if it is absolutely necessary!
±
WARNING! The shaft must always have minimum overlap of half a shaft length!
The recommended overlap (A) of the two shaft parts is 2/3 of the length. The shaft must always have minimum overlap (A) of 1/2 of the length.

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 for Tractor
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.
μ
ATTENTION! The hydraulic hoses are marked with arrows to indicate the direction of oil flow.
μ
ATTENTION! The hydraulic system requires an oil flow between 25 and 130 l/min and a minimum pressure of 180 bar.
±
WARNING! All hoses MUST be connected. Ensure snap couplers are thoroughly clean before connection. Failure to do so will cause premature wear to the blower hydraulics.
Closed Centre Hydraulics
The sprayer is delivered for use with open centre hydraulic
systems. If the tractor is equipped with closed centre (load sensing)
hydraulics, the bypass on the hydraulic valve block on the sprayer
needs to be blocked off.
The sprayer is supplied
with an extra 1/2” brass nipple with no
perforation.
To convert the sprayer for closed centre hydraulics:
1. Disconnect hydraulic hose A
2. Swap standard 1/2” black nipple B with brass nipple C
3. Connect hydraulic hose A.
4 - Sprayer Setup

Open Centre Hydraulics
The open centre hydraulics block is necessary, if the tractor uses open centre hydraulics and/or load sensing.
Model without electrical activated boom lift
The valve is factory set for open centre hydraulics, but if closed centre hydraulics is used (also in combination with load sensing), screw in the valve (clockwise).
±
WARNING! Before operating the hydraulics, the valve should be set 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 open or close the open/closed centre selection valve. Failure to do so may cause damage to vital pump parts.
Load sensing hydraulics
Certain 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” nipple with an
0.7 mm orifice (HARDI item no. 146851).
Model with electrical activated boom lift
The valve (1) is factory set for open centre hydraulics, but if closed centre hydraulics is used (also in combination with load sensing) then screw in the valve (clockwise).
Certain tractor models are able to use Load Sensing without connecting an external sensing line. But if optimal sensing control pressure cannot be obtained, an external sensing line needs to be connected (3). Please consult your tractor dealer for correct setup and correct connection.
Before operating the hydraulics, the valve should be adjusted according to the specific tractor model. If you have doubt about which type of hydraulic system your tractor is equipped with, please consult your tractor dealer.
Combinations of settings for flow element and circuit value:
*if the tractor requires pressure relief, contact your tractor dealer for further advice.
±
WARNING! Always be sure to fully open or close the open/closed centre selection valve (1). Failure to do so may cause damage to vital pump parts.

Speed Transducer for Tractor
Note the following if the speed transducer is fitted to the tractor.
The speed transducer (A) 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. a bolt head) passing by in order to trigger a signal. It should be adjusted, so that the 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 a constant flashing of the transducer, when the wheel is rotating.
Road Safety Kit
The sprayer can be equipped with rear lights. Connect the plug for rear lights to the tractor’s 7-pin socket and check the function of rear lights, stop lights, side lights and direction indicators on both sides before driving.

Liquid system
Self-Cleaning Filter - Choice of Restrictor
It is important to have a large flow through the filter. This is achieved by choosing the restrictor size in relation to the liquid consumption of the spray boom. 4 restrictors are supplied. Use the green one with largest orifice (A) first.
Remove the hose (N) from the filter. Be careful not to loosen the seal. Place the restrictor in the hose and mount the hose again.
If the required working pressure cannot be obtained, the restrictor is too large. Choose a smaller restrictor. Start with a black one, then a white and finally a red one.
When cleaning the filter, remove the hose (N) and the hose at the safety valve and check that there are no residues.
Standard filter size is 80 mesh. Filters of 50 and 100 mesh are available and can be changed by opening the filter top.
Check the condition of the O-rings before reassembly and replace them if damaged.
Adjustment of EVC Operating Unit
Adjust the EVC operating unit before spraying, using only clean water (without chemicals).
1. Choose the correct nozzle for the spray job by turning the TRIPLET nozzle bodies. Make sure that all nozzles are of the same type and capacity. See the “Spray Technique” book.
2. Set the main ON/OFF switch to ON at the spray control unit.
3. Turn all distribution valve switches ON at the spray control unit.
4. Press down the pressure regulation switch at the spray control unit
until the emergency handle on the valve stops rotating (minimum pressure).
5. Put the tractor in neutral and adjust the PTO and thereby the number of revolutions of the pump corresponding to the intended travelling speed. Remember to keep the number of revolutions of the PTO between 300-600 rpm (pump 540 rpm) or 650-1100 rpm (pump 1000 rpm).
6. Push up the pressure regulation switch at the spray control unit, until the required spray pressure is shown on the pressure gauge.
Adjustment of pressure equalization:
7. Close the first section valve on the spray control unit.
8. Turn the adjusting screw for the corresponding valve, until the pressure gauge shows the same pressure as when all
sections were open.
9. Open the section valve again.
10. Adjust the next section valves in the same way.
μ
ATTENTION! Hereafter adjustment of pressure equalization will only be needed when:
you change to nozzles with other capacities
the nozzle output increases, as the nozzles wear out
4 - Sprayer Setup
42
BoomPrime Adjustment
The BoomPrime system (optional) works within a fixed pressure range of around 3 bar, but it must be adjusted for the specific spray job (different choice of nozzles etc.):
1. Unfold the boom and start the PTO.
2. Set pressure valve to “Spraying”, suction valve to “Main tank” and
agitation valve to “Agitation”.
3. Adjust the spray pressure to what will be used when spraying.
4. Turn the BoomPrime adjuster screw (A) to increase the BoomPrime
pressure to 3 bar or until the nozzles start to leak.
5. If nozzles leak, then lower the BoomPrime pressure by 1 bar on the adjuster screw (A).
μ
ATTENTION! If not adjusted correctly, nozzles will not close (i.e. will leak) when the spraying is stopped or it will not prime the tubes.
The possible priming circulation speed of BoomPrime relies on the non­drip valves to keep the nozzles closed. If an extended amount circulation may be necessary, the non-drip valves can be changed to a version with higher pressure setting (later opening time).

Liquid System
Filling/Washing Location Requirements
When filling the sprayer with chemicals and water, it is important to avoid spot contamination by spraying chemicals in order to protect the subsoil water resources.
At a dedicated filling site
If the sprayer is always filled on the same location, a special filling/washing location should be established. This should have a hard, liquid-impenetrable surface (e.g. concrete) securing against seepage, together with edges securing against run-off to the surrounding areas. The location 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 in a larger area. This is 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 can be used. Filling location must be no closer than:
1. 50 metres from public water supplies for drinking purposes, and
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.
In the field
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 take place 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.
μ
ATTENTION! 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
49
Filling Through Tank Lid
Water is filled into the tank by removing the big tank lid, which is located at the top of the tank on the sprayer’s right side. The tank lid is accessible from the optional footboard. It is recommended to use as clean water as possible for spraying purposes. Always fill water through the strainer basket to prevent foreign particles from entering the tank. An overhead tank can be used in order to obtain high filling capacity.
±
WARNING! Do not let the filling hose enter the tank. Keep it outside the tank, pointing towards the filling hole. If the hose is led into the tank, and the water pressure drops at the water supply plant, chemicals may be sucked back and contaminate the water supply lines, supply plant and supply well.
±
WARNING! The water supply line should be provided with a check valve as additional safety precaution. Follow local legislation in force at any time.
±
WARNING! The water supply should be provided with a water meter to avoid spillage by overfilling. Follow local legislation in force at any time.
Filling of Rinsing Tanks
Two rinsing tanks are fitted to the sprayer, they are filled via the lid on the top of the tanks:

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 if it requires facilities which are not available, then please leave the job to your HARDI dealer’s workshop for safety reasons.
μ
ATTENTION!
Clean sprayers are safe sprayers.
Clean sprayers are ready for action.
Clean sprayers cannot be damaged by pesticides and their solvents.
Guidelines
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.
Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods, etc. Contact the appropriate authority if you are in doubt.
Pesticide washings can usually be sprayed out on the field just sprayed or at a suitable cultivated area. Avoid emptying the washings at the same spot every time and keep sufficient distance to the water environment. You must prevent seepage or runoff of residue into streams, watercourses, ditches, wells, springs, etc. The washings from the cleaning area must not enter sewers. Alternatively the washings can be retained in an appropriate receptacle, diluted and distributed over a larger cultivated area - see also “Filling/Washing Location Requirements” on page 48.
Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining spray liquid.
It is good practice to clean the sprayer immediately after use, and thereby rendering the sprayer safe and ready for the next pesticide application. This also prolongs the life of the components. It is strongly advised to perform an internal cleaning of the sprayer, when high concentrations of acids or chloride are present in the active ingredients, or if the spray liquid is corrosive. For the best result, use a cleaning agent recommended by HARDI, e.g. AllClearExtra.
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, children and animals must not have access to the sprayer under these circumstances.
If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after use with a suitable rust inhibitor.
The sprayer must always be parked under roof to avoid rain washing off pesticides as well as build-up of spot contamination in the soil. If parked outside, the sprayer should be parked on the filling/washing location in order to retain possible pesticides.

Cleaning the Tank and Liquid System
μ
ATTENTION! Thorough cleaning of the sprayer is to be carried out when shifting to crops, which are very sensitive to chemicals just sprayed, or prior to storage for a longer period of time.
÷
NOTE! Prior to the described cleaning, a standard cleaning should be carried out.
Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivating agents if necessary.
Rinse and clean sprayer and tractor externally. Use detergent if necessary.
1. Remove tank filters and suction filters and clean the sprayer. Be careful not to damage the filter mesh. Put back the
suction filter top. Put back all filters, when the sprayer is completely clean.
2. With the pump running, rinse the inside of the tank. Do not forget to clean the tank roof. Rinse and operate all components and any equipment, which 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 or on the seepage location.
3. 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 effect ammonia. Special detergents for sprayer cleaning is recommended as some also lubricate ball valves etc.
4. Start the pump and operate all controls enabling the liquid to come into contact with all the components. Operate the distribution valves as the last thing. Some detergents and deactivating agents work best, if they are left in the tank for a short period. Check the label.
5. Drain the tank and let the pump run dry. Rinse inside of the tank, again letting the pump run dry.
6. Stop the pump. If the pesticides used have a tendency to block nozzles and filters, remove and clean them
immediately.
7. Put back all the filters and nozzles and store the sprayer. If it is noted, from previous experiences, that the solvents in the pesticides 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 spraying pressure to 1.5 bar, 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 washer, lubrication of the entire machine is recommended.
Cleaning and Maintenance of Filters
Clean filters ensure:
Sprayer components such as valves, diaphragms and operating units 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
components is the suction filter. Check it regularly.

4. Disengage pump again.
μ
ATTENTION! If the sprayer is cleaned with a high pressure washer, lubrication of the entire machine is recommended.
Use of Detergents
It is recommended to use an appropriate cleaning detergent suitable for cleaning agricultural sprayers.
Cleaning detergents containing a suitable lube or conditioner are recommended.
If for some reasons this is not available, and e.g. triple ammonia water is used, it is important to rinse the spray circuit
immediately after and add some lubricant to the rinsing water to prevent ball valves etc. seizing up.
Use of automotive antifreeze/radiator coolant (ethylene glycol) will protect valves and seals from drying or seizing up.
Technical Residue
An amount of spray liquid will inevitably remain in the system. It cannot be sprayed properly on the crop, as the pump takes in air, when the tank is just about empty.
This technical residue is defined as the remaining amount of liquid in the system, when the first clear pressure drop appears on the pressure gauge.
The residual dilutable volume is approx. 16 litres. See the section “Technical Specifications” for more details.
The residues in the tank should be diluted immediately in a ratio of 1:10 with clean water. Afterwards it should be sprayed on the crop just sprayed with increased driving speed. In addition, also pump, linkage and armature can be separately rinsed with water from the rinsing tank. However, it must be ensured that the liquid in the spray lines are in unchanged concentration. Therefore there should be an untreated field area available to spray this liquid out.

Using the Drain Valve
The drain valve is operated from the right side of the sprayer’s front.
1. Pull the string to open the drain valve.
2. The valve is spring-loaded, but can be kept open by pulling the
string upwards in the V-shaped slit.
3. To release, pull the string downward and the valve will close automatically.

Operating Limits
The following things are important when considering the performance of the sprayer.
Maximum driving speed
Pressure setting
Minimum / maximum flow rate
The operating limits for your sprayer are closely related to:
4. Pump size
5. Boom width
6. Nozzle size
In the table below, the operating limits for volume rate are calculated, when driving at different speeds.
÷
NOTE! The specified nozzle type is a standard flat fan nozzle. Other special nozzle types will show different results. Ask your HARDI dealer if in doubt.
μ
ATTENTION! It is recommended not to drive faster than 16 km/h when spraying.
μ
ATTENTION! The pressure range for the nozzles are 1.5 - 5 bar (except for HARDI INJET nozzles, which are ranging from 3-8 bar). The spraying pressure should be within these limits.

Liquid Fertilizer
Spraying pressure
If you are spraying with liquid fertilizer instead of pesticides, the spraying pressure must be increased in comparison to pesticide spraying to get the desired output (l/ha).
The density for liquid fertilizer is normally higher than for water and spray liquids - so to get the correct output (l/ha), the spraying pressure must be adjusted.
Example: Nozzle output is 2.40 l/min at 3.0 bar pressure. Density of liquid fertilizer is 1.20 g/cm³.
Multiply the pressure value with the density value: 3.0 x 1.2 = 3.6; the adjusted pressure is then 3.6 bar for spraying the liquid fertilizer.
In the table below, adjusted pressure values can be found for different densities of liquid fertilizers.
μ
ATTENTION! Pressure values below 1.5 bar or above 5.0 bar are considered to be out of range for the nozzles.
÷
NOTE! Find the density for your liquid fertilizer on the packaging or on the material safety data sheet (MSDS) included.

Lubrication
General Info
Always store lubricants clean, dry and cool - preferably at a constant temperature - to avoid contamination from dirt and condensed water. Keep oil filling jugs, hoppers and grease guns clean, and clean the lubricating points thoroughly before lubricating. Avoid skin contact with oil products for longer periods.
Always follow the quality and quantity recommendations. If no quantity is recommended, feed the lubricator until new grease becomes visible.
Pictograms in lubrication & oiling plans designate:
1. Lubricant to be used (see “Recommended lubricants” below).
2. Recommended intervals. Shown in hours or with a symbol for
occasional maintenance.
3. Amount to be used. Only shown if an amount is specified.
μ
ATTENTION! If the sprayer has been cleaned with a high pressure washer, lubrication of the entire machine is recommended.

Grease Gun Calibration
Before lubricating the sprayer, you must calibrate your grease gun to ensure that the correct amount of grease is applied to each lubrication point. The correct amount of grease applied will prolong the lifetime of the sprayer.
Calibration example
1. Insert the correct grease cartridge in your grease gun.
2. Apply grease onto a tissue or a piece of paper. Complete 10 full
strokes of the grease gun.
3. Place the paper with grease on a scale (A).
4. If your grease pile weighs for example 10 grams, then 1 stroke
equals 1 gram of grease.
When calibrated, you can count how many strokes to complete, when lubricating the different grease points on the sprayer according to the specifications.
Alternative method
1. Count the strokes, until you have 10 grams of grease piled up on the scale (A).
2. Now you can figure out how many strokes to use for applying a certain amount of grease to a lubrication point.
Lubrication & Oiling Plan - PTO
μ
ATTENTION! The correct amount of grease applied at the intervals is important. Too little or too much grease will shorten the lifetime of the PTO.
The amount of grease to be applied is mentioned in grams (g). Test your grease gun to see how many grams it provides, for example after 5 strokes.
The grease points and amount of grease to be applied are shown in the pictures below together with the intervals.

Shield Replacement on Transmission Shaft
See the manufacturer’s instruction book.
Replacement of Transmission Shaft Cross Journals
See the manufacturer’s instruction book.
Change of Light Bulb
1. Switch off the light.
2. Loosen the screws on the lamp and remove the cover or lens.
3. Remove the bulb.
4. Fit a new bulb, refit the cover and tighten the screws.
μ
ATTENTION! If halogen bulbs are used, never touch the bulb with your fingers. Natural moisture in the skin will cause the bulb to burn out, when the light is switched on. Always use a clean cloth or tissue when handling halogen bulbs.
Change of Tyre
DANGER! If it is time to change tyres, it is recommended to leave this job to a specialist and follow the rules below. Some mounting instructions are usually printed on the tyre itself.
Always clean and inspect the rim before mounting a new tyre.
Always check that the rim diameter corresponds exactly to the rim diameter moulded on the tyre.
Always inspect the tyre inside for cuts, penetrating objects or other damages. Repairable damages should be repaired
before installing the tube. Tyres with non-repairable damages must never be used.
Also inspect the tyre inside for dirt or foreign objects. Remove this before installing the tube.
Always use tubes of recommended size and in good condition. When fitting new tyres, always fit new tubes.
Before mounting, always lubricate both tyre beads and rim flange with approved lubricating agent or equivalent
anticorrosion lubricant. Never use petroleum based greases and oils, because they may damage the tyre. Using the appropriate lubricant will prevent the tyre from slipping on the rim.
Always use specialised tools for mounting the tyres as recommended by the tyre supplier.
Make sure that the tyre is centred, and that the beads are perfectly seated on the rim. Otherwise tearing of the bead
wire may occur.
Inflate the tyre to 1-1.3 bar (14.5-19 psi), then check whether both beads are seated perfectly on the rim. If any of the beads do not seat correctly, deflate the assembly and re-centre the beads, before starting inflation of the tyre. If the beads are seated correctly on the rim at 1-1.3 bar (14.5-19 psi), inflate the tyre to a maximum of 2.5 bar (36 psi), until they seat perfectly on the rim.
Never exceed the maximum mounting pressure moulded on the tyre!
After mounting tyres adjust inflation pressure to operation pressure recommended by the tyre manufacturer.
Do not use tubes in tubeless tyres.
DANGER! No observance of mounting instructions will result in a bad seating of the tyre on the rim, and it could cause the tyre to burst leading to serious injury or death! DANGER! Never mount or use damaged tyres or rims! Use of a damaged, ruptured, distorted, welded or brazed rim is not allowed!

Readjustment of Boom - General Info
Before commencing adjustment jobs, please go through this check list.
1. The sprayer must be well lubricated (see the section “Lubrication”).
2. Connect the sprayer to the tractor.
3. Place tractor and sprayer on level and solid ground.
4. Activate parking brake for tractor.
5. Put wedges under the wheels to prevent rolling.
6. Unfold the boom.
7. Place strong supports below the centre section and all boom sections to relieve the load from the hydraulic cylinders.
If you have a lifting crane, support the centre sections as a minimum, as this is the heaviest boom part (up to 1000 kg).
8. Set slanting angle to neutral position (horizontal).
±
DANGER! No one is allowed under the boom, while the adjustment is carried out.
±
DANGER! Adjustment of hydraulic cylinders is to be carried out without pressure in the system.
μ
ATTENTION! For information on boom terminology, “Boom and Terminology” on page 26
μ
ATTENTION! To check the boom alignment, you can use a spirit level, or you can measure the distance to the ground from similar points in both ends of the boom wing (this method is used for horizontal alignment and only on level ground). When using the latter method, both distances should be equal to obtain a horizontal boom.
μ
ATTENTION! Boom sections, which are not support during adjustment jobs, might fall down or be difficult to adjust.
μ
ATTENTION! Adjustments are to be completed equally for both right and left boom wings.
μ
ATTENTION! The following types of arrows are used when describing the different boom adjustments:
Boom Lift Adjustment
If slack occurs (= backward and forward movements of the boom), the slide arrangements (A) should be adjusted.
1. If there is too much space between the slide block (B) and the steel frame, extra shims (C) should be mounted in between.
2. If the slide block (B) or the shims (C) are worn, they should be replaced.
3. Loosen the bolts and nuts to separate the parts. Replace parts as needed and tighten the bolts and nuts again.
4. Each slider arrangement should be adjusted, until the same clearance has been reached at all 4 sliders.
μ
ATTENTION! It is very important that the boom carrier does not run unequally in the H-frame. It is important that there is no play in any of the sliders.

Boom Adjustment Order
Carry out adjustments in the following order:
1. Trapeze suspension and center section.
2. Inner wing sections.
3. Outer wing section.
4. Breakaway section.
Trapeze Locking Device
The trapeze helps the boom to stay horizontal when unfolded and it protects the boom against vibrations and impacts.
In order to lock the boom during folding, the chains must be tight. If this is not the case even when the cylinder is fully retracted, the chains must be tightened.
Glide Shoes - Yaw Damping
If slack occurs (backward and forward movements of the boom), adjustment of yaw damping is needed.
This is done by slightly tightening the bolts (A).
Be careful not to overtighten or squeeze the rubber bushings (B). Only tighten until there is no more play!

Off-Season Storage
Off-Season Storage Program
To preserve the sprayer intact and to protect its components, the following off-season storage program is carried out.
Before storage
When the spraying season is over, you should devote some extra time to the sprayer.
If chemical residues are left over in the sprayer for longer periods, it may reduce the life of its individual components.
1. Clean the sprayer completely - inside and outside - as described under “Cleaning” on page 60. Make sure that all valves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so that no chemical residues are left in the sprayer.
2. Replace 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. The rinsing tank is also drained.
4. Pour approximately 50 litres of antifreeze mixture, consisting of 1/3 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 antifreeze
mixture to be distributed around the entire circuit. Open the operating unit main valve ON/OFF and distribution valves, so that the antifreeze is sprayed through the nozzles as well. The antifreeze will also prevent O-rings, seals, diaphragms etc. from drying out. On sprayers with a FlexCapacity pump, this must also be engaged and flushed.
6. Lubricate all lubricating points according to the lubricating intervals.
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 moisture, dirt and corrosion.
12. Remove the control boxes and computer display from the tractor. Store them dry and clean (indoor) in a non-
condensing environment.
13. Wipe hydraulic snap couplers clean and fit the dust caps.
14. Apply grease to all hydraulic ram piston rods, which are not fully retracted in the housing, to protect against corrosion.
15. To protect against dust, the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.
After storage
After a storage period, the sprayer should be prepared for the next season the following way:
1. Remove the tarpaulin.
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 antifreeze.
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
Operational incidents are often due to the same reasons:
A suction leakage reduces the pump pressure and may interrupt suction completely.
A clogged suction filter may damage suction or interrupt and prevent the pump from running normally.
A clogged pressure filter increases pressure in the fluid system in front of the pressure filter. This may blow the safety
valve.
Clogged in-line filters or nozzle filters increase pressure in the pressure gauge, but it decreases pressure at the nozzles.
Impurities sucked in by the pump may prevent the valves from closing correctly, thus reducing the pump flow.
A bad reassembly of the pump elements, especially the diaphragm covers, causes air intakes or leaks and reduces the
pump flow.
Rusted or dirty hydraulic components cause bad connections and early wears.
A poorly charged or faulty battery causes failure and misbehaviour in the electrical system.
Therefore ALWAYS check that
Suction and pressure filters, as well as nozzles, are clean.
Hoses are free of leaks and cracks, especially suction hoses.
Gaskets and O-rings are present and in good condition.
Pressure gauges are in good working order. Dosage accuracy depends on it.
Operating unit functions properly. Use clean water to check.
Hydraulic components are clean.
The tractor battery and its connectors are in good condition.
