3 - Description

Sprayer use

The HARDI sprayer is for the application of crop protection chemicals and liquid fertilisers. 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 avoid unnecessary risk for persons and the environment when doing your spray job.

Frame

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.

Tanks and equipment

The main tank made of impact-proof, UV-resistant and chemical resistant polyethylene, 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 is also equipped with a rinsing tank and a clean water tank. A large, easy to read tank contents indicator is placed beside the platform and is visible from the tractor cabin.

Nominal contents 3300, 4500, 5500 or 7000 litres.

3 - Description

Liquid system

Pump

Diaphragm pump with 6 diaphragms, model 463. Standard = 540 r.p.m. (6 splines shaft). Optional = 1000 r.p.m. (21 splines 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.

FlexCapacity pump

Some sprayers facilitates a dual pump setup with an extra hydraulically driven pump of same type as the main pump, placed on sprayers right side.

The FlexCapacity pump is turned ON/OFF with a separate hydraulic lever in the tractor cabin.

Valves and symbols

The possible functions of valves are distinguished by coloured identification on the function labels. The modular valve system facilitates the addition of optional extras on both pressure side and suction side. A function is activated by turning the handle towards the desired function.

ATTENTION! Only the functions used should be open - always close remaining valves.



ATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be serviced. Please see



“Pump valves and diaphragms renewal” on page 93 for further information.

Pressure SmartValve (Green symbols)

This valve is to select which function the pressurized liquid from the pump will be routed to.

The active function is indicated by the indicator. The handle is turned so the indicator points to the label for required function. If handle is turned to a position without label (unused function) then the valve is closed.

Main tank Spraying

Internal tank cleaning (Rinsing nozzles)

Suction SmartValve (Blue symbols)

This valve is to select suction from main tank or from the rinsing tank.

The handle is turned so the label for required function is directed to the indicator. If handle is turned to vertical position (indicator not pointing at a label) then the valve is closed.

Main tank Rinsing tank

Pressure draining (optional) or TurboFiller

External filling (optional)

3 - Description

DynamicFluid4 pressure regulation

Traditional fluid regulation starts when the nozzles are opened. With DynamicFluid4 the regulation is a continuous process that continues even if the nozzles are closed. Two ceramic discs regulates the pressure and ensures quick reaction and zero leakages. Sprayer speed, P.T.O. RPM and number of sections activated are parameters used, and the benefit is more precise application rates from the second the sprayer begins spraying.

The DynamicFluid4 use feed forward technology based on 5 sensors that feeds the JobCom computer with data necessary for optimal regulation. It auto-prime at start-up, starts and move the valve towards the final position immediately after the operator makes changes. E.g. when section valves are opened or closed, the regulation valve is started at same time as the section valve motors are started. This avoids overpressure situations e.g. after running empty and refill of main tank.

The 5 sensors are also back-up for each other and ensures the system can continue regulation even if one or more sensor signal fails. Sensors used are:

• Sprayer speed sensor

• Flow sensor

• Pressure sensor

• Pump r.p.m. sensor

TWIN Air technique

General info

With TWIN air assistance energy is added to the spray droplets to improve control with the spray liquid. The main purpose of the TWIN angling system is to counteract for the negative influence which wind direction and driving speed have on the quality of the spray job. Further the “co-angling” af air and liquid can help “opening” dense crops for better penetration.

This way TWIN makes it possible to:

• carry the spray droplets safely to the target and increase plant deposit.

• minimize off-target deposit due to wind drift or loss on the ground.

• open the crop and obtain good penetration even with a low

volume rate.

• ensure a high coverage.

The TWIN FORCE air system can be set at any angle from 40° forward to 30° back (defined by the air stream). The fan speed is infinitely variable and can produce from 0 to 35 m/s (78 mph) air speed at the air outlet. This equals from 0 to 2000 m3 air/m boom/hour (3.872 CFM/A boom/hour).

3 - Description

Boom

Boom and terminology

The TWIN FORCE boom are found in two hydraulic versions which is suspended in a strong, stable parallelogram boom lift:

• HAY boom:

Working widths are 18, 20, 21, 24, 27, 28 and 30 metres.

The boom is pendulum suspended and equipped with 4 hydraulic rams. The raising/lowering and folding/unfolding functions are operated via the tractor hydraulics.

• HAZ boom:

Working widths are 18, 20, 21, 24, 27, 28, 30, 32, 33 and 36 metres.

The boom is pendulum suspended and fully hydraulically operated, all functions are controlled via the Direct Acting Hydraulic System (D.A.H.). The 32-36 metres booms is fully hydraulically operated, all functions are controlled via the Direct Hydraulic System (D.H.).

Boom features

• All booms are 2-folded.

• TWIN blowers. These are driven by a built-in hydrostatic transmission powered via the tractor P.T.O. Blower speed can

be adjusted step wise from the tractor cabin.

• Outer sections incorporate spring-loaded breakaway.

• Hydraulic pendulum lock (HAZ only).

• Individual boom tilt control (HAZ only).

• Individual folding of outer sections. This enables alternative boom widths.

The boom can be used in half folded position. Half folded lengths are the following:

Hydraulic systems

Hydraulic blocks

Hydraulic blocks fitted to the sprayer are:

Boom

The main boom hydraulic block that manages hydraulic pressure for the boom controls.

The throttle valve (A) can adjust the folding speed of the boom. Adjusting inwards = slower boom.

ParaLift

This hydraulic block manages hydraulic pressure for the ParaLift.

Open centre hydraulics

The open centre hydraulics block is necessary if the tractor uses open centre hydraulics and/or load sensing. For adjustment see “Open centre hydraulics (optional)” on page 44.

SafeTrack

On sprayers with SafeTrack steering this hydraulic block manages hydraulic pressure for the steering functions.

3 - Description

AutoHeight UC5

On sprayers with AutoHeight this hydraulic block manages hydraulic pressure for the automatic boom height control functions.

3 - Description

Equipment

SafeTrack

The SafeTrack will make the sprayer automatically follow the tractor when turning on headland. The SafeTrack can easily be operated with the hydraulic control unit. SafeTrack has an integrated safety feature which prevents over-steering when the driving speed is too high for the given turning radius. If a TankGauge is fitted, the tank filling level is also taken into account.

The SafeTrack is limited to speeds below 30 km/t. Driving in “Auto” with SafeTrack will trigger an overspeed alarm and sprayer will automatically align.

WARNING! During road transport the drawbar must be aligned in centre position. Refer to the HC 6500/9500

controller instruction book for specific instructions.

NOTE! IntelliTrack requires the HC 6500/9500 or ISOBUS controller. More information about the controller can be

found in the separate instruction book.

Driving technique for SafeTrack

A trailer with SafeTrack behaves differently than a normal trailer. In tracking position the vehicle centre of gravity is displaced more outward compared to the vehicle centre line of a normal trailer. Compared to a conventional trailer a steered trailer has decreased stability when turning, especially when turning on hillsides (B).

To avoid overbalancing, pay attention to these guidelines:

• Avoid sudden, tight turns.

• Slow down before entering a curve or turning, and drive with a

constant, low speed during the turn.

• Never slow down too fast, never brake heavily and never stop suddenly in a curve, or when turning on a hillside, when the sprayer is articulated.

• Be careful when turning on uneven ground.

• Set the track width (A) as wide as possible.

• The proper function of the hydraulic system is essential to obtain

good stability.

• A filled rinsing tank will increase stability.

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

€

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

Platform

To get access to the platform pull and tilt the ladder down. In retracted position the ladder is secured by a rubber stop.

From the platform following can be accessed:

• Main Tank lid.

• Clean water tank lid, integrated to the side of the platform.

• Lift and remove the platform floor (A) to get access to hydraulic

and MANIFOLD components underneath the platform floor.

• Electronics and optional fast filler are situated behind the cover (B).

• Pressure gauge, EasyClean filter clogging indicator and level

indicator for the rinsing tank are visible here.

ATTENTION! Always tilt up the ladder before driving.

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.

DANGER! For the safety of yourself and others, the following rules should always be observed:

€

Never point the water jet at people, animals, electrical installations or other sensitive objects. Never try to clean clothing or footwear which you or other people wear.

Nozzle pressure gauge

The remote pressure gauge is integrated at the top of the platform. 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.

3 - Description

SafetyLocker

The locker is integrated to the front just above the SmartValves. It is for the purpose of storing 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 and facilitates a soap dispenser (A).

WARNING! Although this locker is meant for storing nontoxic

items, it must never be used for storing food, beverage or other things meant for consumption.

General info

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.

ATTENTION! Only lift the sprayer when the tanks are empty!



4 - Sprayer setup

Pulling the sprayer at the tie down hooks

For moving the sprayer or loading it to e.g. a truck it can be pulled in the hooks at the rear-end (A) and front-end (B) as shown.

COMMANDER 3300/4500

COMMANDER 5500/7000

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 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.

4 - Sprayer setup

Hydraulic support leg (option for CM 3300/4500)

The hydraulic support leg is driven by a separate double acting hydraulic outlet on the tractor. The support leg is stored in its retracted position when the sprayer is attached to the tractor.

To raise/lower the support legs

1. Pull the knob (A) to fold-up/down the support leg to/from its storing position.

NOTE! This does not apply to the CM 5500/7000 support leg.

2. Unlock the leg by turning the securing grip to position (A).

3. Use the tractor’s hydraulic lever to raise or lower the support leg.

4. Secure the leg by turning the grip to position (B).

DANGER! Do never leave the sprayer standing unlocked on the

€

support leg. Always double check that the lever is in position (B).

Jack up the sprayer

When the sprayer needs wheel mounting, wheel changing, brake or wheel bearing changing etc. then jack up the sprayer under the axle as shown.

DANGER! Be sure to place sprayer at level and firm ground to

€

avoid sprayer falling down from the jack.

ATTENTION! It is good practice to use stop wedges at the



opposite wheel!

4 - Sprayer setup

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.

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

6. Make sure that protection guards around the tractor P.T.O. 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! ROTATING TRANSMISSION SHAFTS WITHOUT PROTECTION GUARDS ARE FATAL.

€

P. T. O. i ns t a l la t i o n

Always read the manufacturer’s instruction book before applying any installation of 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 P.T.O. 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! Do only shorten the shaft if 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.

DANGER! As P.T.O. shafts are dangerous, always read the

€

manufacturer’s instruction book before applying any changes to the transmission shaft!

4 - Sprayer setup

Mechanical connections

Hose package support

To prevent hoses and wiring from being damaged by the tractor wheels, P.T.O. shaft etc. all hoses, cables and wires are held by the hose package support fitted to the sprayer platform.

The bracket (A) is for the storing of hydraulic and electric connectors etc. when the sprayer is disconnected from the tractor. The height of the bracket can be adjusted by the means of the bolts (B).

ATTENTION! Check that the length of the hoses and cables are



sufficient by tight turns.

ATTENTION! A sprayer with SafeTrack requires more slack in the cables. Make sure cables are long enough in tight



turns when fully steered.

SafeTrack potentiometer connection

When connecting the SafeTrack sprayer to the tractor it is important to set up the front potentiometer on the drawbar correctly. The potentiometer must be connected to the tractor with the supplied 2 chains.

NOTE! To ensure a high precision the chains must be parallel and

horizontal.

NOTE! To ensure a high precision the tractor hitch point may not

have any sidewards movement.

Procedure when connecting the sprayer to the tractor:

1. Connect the sprayer.

2. Drive forward to ensure the sprayer follows the tractor in a straight line.

3. Connect the two chains for the potentiometer, while ensuring the transverse potentiometer bar is perpendicular to

the drawbar. The chains must be parallel and horizontal, and tightened so that the torsion levers (A) are vertical.

4. Check if the potentiometer is reading 2.50 Volt, i.e. in centre position. Go to:

HC 6500 / ISOBUS VT: Menu 4.5.4.6 Track sensor test and check if the Front sensor reading is 2.50 Volt.

5. If the voltage reading is not correct, then adjust the chain connection until voltage = 2.50 Volt. Allowable deviation is ±0.05 Volt.

4 - Sprayer setup

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

Speed transducer for sprayer

The speed transducer and speed ring are located at the inside of the sprayers right wheel. The sensor is an inductive type that requires a metallic protrusion like a speed ring to pass by it to trigger a signal.

Adjustment

1. Assure that the speed ring is correctly fitted to the wheel, so that the arrow (A) follows the forward rotation of the wheel.

2. Adjust so the sensor lines up in the middle of the gaps in vertical direction. Distance from centre of the sensor to top of the brake drum:

• 412 mm brake drum = 60 mm

• 400 mm brake drum = 75 mm

ATTENTION! If necessary readjust plate on the axle.

SmartValve is turned to the unused position and the pressure SmartValve is turned to “Main tank”. Otherwise, spraying liquid may hit you when opening the filter, and drain from the main tank!

Boom

Damping adjustment

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

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

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

To obtain less damping: Throttle valve (A) must be screwed outward.

Boom folding speed adjustment

There are restrictors for adjusting of boom folding speed - one per each boom wing. The restrictor are located near the big pendulum damping cylinder.

4 - Sprayer setup

Adjustment

• To decrease folding speed:

Loosen counternut (arrowed) and to adjust folding speed valve (arrowed) must be screwed inward. Lock counternut again.

• To increase folding speed:

Loosen counternut (arrowed) and to adjust folding speed valve (arrowed) must be screwed outwards. Lock counternut again.

ATTENTION! The system must not be pressurized during



adjustment.

TWIN Air technique

Adjusting the air assistance

The air speed and angling must always be adjusted individually for each spray job and the given weather conditions. It is always a good idea to get used to a new sprayer out in a field with only water in the tank, on this occasion the following routine for air adjustment should be practised:

1. Start with the air vertical

2. Set the air speed: See section “Setting of air speed, rules of thumb”

3. Find the best angling: See section “Angling of air and liquid, rules of thumb”

4. Readjust the air: See section “Setting of air speed, rules of thumb”

ATTENTION! Fine tuning of air speed and angling will often be necessary all through the spraying job.



ATTENTION! It is easiest to find the best air setting to reduce drift when the sun is low and behind the boom



(backlight). These conditions make the drift more visible.

Setting of air speed, rules of thumb

Step 1

Find the range of air speeds that can control drift

1. Start with the air setting at zero and keep increasing the air speed just to the point where you can see that the drift cloud is minimised - note minimum setting.

2. Then increase the air speed until you see drift again - note maximum setting.

3. Now you know the range of air speeds that can be used with minimum drift.

Bare ground / low crop: The range of air speeds is usually very small.

Taller crop: The taller the crop the wider the range of air speeds that can reduce drift.

At higher wind speeds: More air is needed on the sprayer and it is advisable to drive more slowly and use minimum boom height (40 cm)/(16 in).

Too high air speed over bare ground/low crop can cause reflection of the spray liquid and leave dust on the leaves, which can again reduce the effect of the plant protection product.

Step 2

Set the optimal air speed within possible the range mentions above.

Air speed recommendations:

Bare ground / low crop: Use maximum air within the possible range.

Taller crop: Deeper crop penetration requires more air on the sprayer (if you are in doubt check with water sensitive paper).

Forward speed: Higher forward speeds require more air on the sprayer.

Volume rate: Lower volume rates require more air assistance to prevent drift.

4 - Sprayer setup

Angling of air and liquid, rules of thumb

To control wind drift the influence of wind speed and wind direction as well as the horizontal air current around the boom due to forward speed must be minimised. Because it is a sum of two forces with variable direction and size that we have to counteract for, the following can only be very rough guidelines.

Wind direction

• Head wind: Angle forward.

• Down wind: Angle back (if the forward speed is higher than the wind speed: angle forward).

• Side wind/no wind: Angle vertical or back. Only high forward speeds may require forward angling.

Crop condition

Bare ground/low vegetation: Low air speed and angling back will often be the best setting to avoid reflection of spray liquid.

Dense crop: The angling feature is ideal to help opening the canopy and improve penetration. If you follow the crop movement as you are varying the angling you will find that at certain settings the crop will open more for penetration.

If wind speed, wind direction or for some reason forward speed changes during spraying the optimum angling is likely to change too. Be aware that with certain combinations of air speed and angling you can “close” or flatten the crop and make penetration impossible - follow the crop movement intensively especially when setting the air assistance and keep an eye on the crop all through the application.

• It is most important that the sprayer operator is familiar with the above rules of thumb before using the TWIN sprayer.

• All volume rates, pressures and air adjustments stated in the following tables are, of course, guiding. Special conditions

regarding climate, crop quality, spraying time and applied chemical can change the procedure. The tables are showing practice in north ern Europe, and conditions may be very different in other countries. I f you want some lo cal advice you are ver y welc ome to contact the T WIN applic ation expert a t the HA RDI imp orter or daughter company in your country.

• The volume rate can generally be reduced to half of what is applied with a conventional sprayer, but with a minimum of 50-60 l/ha at 7-8 km/h (5.5-6.5 GPA at 4.5-5 mph. Exceptions are of course liquid fertiliser and herbicides whose selectivity is based large droplets that will only stick to the weeds.

• Low drift nozzles can also be fitted on a TWIN sprayer and help reduce drift even further.

• If there is a detailed spraying instruction on the chemical label regarding drop size, spray pressure, spray volume rate

etc. this should be followed. Enclose 1 bag of water sensitive paper and instruction of how to use with all TWIN sprayers.

ATTENTION! Often it will be necessary to drive with two different anglings, so the angling is changed when changing



driving direction after turning at the headland.

Water sensitive paper

USE WATER SENSITIVE PAPER TO HELP FIND THE BEST AIR SETTING.

Some time spent in different types of crops with clean water in the tank and some water sensitive paper will be valuable experience for the future work with your TWIN sprayer. The paper can be cut into smaller pieces (to simulate the target) and fixed with double sided tape at relevant places in the crop. Then spray with pure water and check the blue spots (droplets) on the paper. This way you can test different spraying techniques. Water sensitive paper is available at your local HARDI dealer, part No. 893211.

4 - Sprayer setup

Track gauge, axles and wheels

Altering the track width

The track width of the sprayer can be altered stepless as follows,

Altering procedure

1. Measure the current track width (centre RH tyre to centre LH tyre). Each side must be extended or retracted half the desired alteration.

2. Attach the sprayer to tractor and engage tractor parking brake.

3. Place stop wedges in front of and behind RH wheel. Jack up LH

wheel, support and secure sprayer body.

4. Loosen the counternut at the bolts (A) and the bolts (A) for LH wheel axle.

5. When having a handbrake, loosen the pointed screw (B) on the brake operating arm.

6. Extend or retract the axle. A sack barrow and a rod will facilitate the operation.

7. Lower down the LH wheel.

8. Tighten the clamp bolts (A) to a torque of 250 Nm and lock the

bolts with the counternuts.

9. Repeat the procedure on RH wheel.

10. Check if the distance from centre tyre to centre of rear frame is equal at RH and LH.

11. Retighten bolts and wheel bolts to specified torque after 8 hours of work.

ATTENTION! The wider the track width, the better the stability of the sprayer. HARDI recommends to work with widest



possible track width.

ATTENTION! Depending on configuration of the machine the track width can be altered in the range from 1500 mm



to 2000 mm (narrow version), or from 1800 mm to 2250 mm (wide version) in combination of above adjustment and turning of the rims (offset).

Turning rim

Track width can be altered by turning the rim.

Offset:

+ 61 mm

- 50 mm

ATTENTION! When wheels has been mounted or re-tightened,



the plastic nut covers must be placed on the nuts afterwards.

Counter weight

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

4 - Sprayer setup

Use a mixture of water and CaCl below:

200 g (7.1 oz) CaCl

300 g (10.6 oz) CaCl

435 g (15.4 oz) CaCl

To fill the tyres

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

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

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

body again.

4. Adjust tyre pressure and lower the wheel. Please refer to “ Tyre pressure” on page 118.

DANGER! It is very important that the CaCl2 is added to the water and agitated until it is fully dissolved. Never pour

€

water on to CaCl advice afterwards.

WARNING! The tyres must be liquid filled to max. 75 % of total tyre volume. Fill only the qty. of liquid necessary to

obtain sufficient stability of the sprayer. Do not fill liquid and CaCl

per litre water gives protection to -15°C (30.6°F)

per litre water gives protection to -25°C (12.6°F)

per litre water gives protection to -35°C (-5.4°F)

! If you get CaCl2 in the eyes, flush instantly with cold water for at least 5 minutes and seek medical

to avoid frost damage as described

mixture in tyres without tubes!

ATTENTION! When filling the tyres the valve should be positioned at 12 o’clock and when adjusting the tyre pressure,



the valve should be positioned at 6 o’clock.

To empty the tyres

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

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

appropriate container.

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

4. Remove the drain tube, fit the valve and inflate the tyre to specified pressure. See “Technical specifications” for the table “Tyre pressure”.

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

Brakes

Emergency and parking brake

The parking brake lever has two function modes, which are determined by the small pawl control clip (A). To change between the two modes, turn the clip.

Position Rest position Behavior

1 Rest against the pawl Disengage parking brake

2 Point away from the pawl Engage parking brake/Emergency brake

Disengage the parking brake

1. Set pawl control clip in position 1.

2. Pull the lever a little forward to release the pawl from the ratchet

and then push the lever fully backwards.

Engage the parking brake

1. Set pawl control clip in position 2.

2. Pull the lever firmly forwards until parking brake is fully engaged.

Emergency brake

1. Set pawl clip in position 2.

2. Attach the rope from the hole in top of the hand brake lever to e.g. the tractor top link attaching point (B). If the sprayer

is accidentally unhooked during transport the rope will apply the parking brake before the rope breaks.

ATTENTION! To ensure safe engagement and to avoid damages to the parking brake use rope with an ultimate stress



between 690 N (155 lb.) and 785 N (176 lb.).

WARNING! Relieve the parking brake before driving!

Hydraulic activated brakes

This requires a special trailer brake valve attached to the tractor hydraulic and brake system. Connect the snap coupler to the tractor brake outlet. When the tractor brakes are applied, the trailer brakes will work proportionally to the tractor brakes, and ensure safe and effective braking.

WARNING! Do not connect the brakes directly to the tractor

hydraulics without the brake valve. The trailer brake power cannot be controlled, and braking will therefore be hazardous.

WARNING! Max. oil pressure is 150 bar (2175 p.s.i.) in the brake line.

4 - Sprayer setup

Air activated brakes (optional)

This system requires a tractor with compressor and air brake system with outlet(s) for trailer brakes.

If the air hose(s) are disconnected with air in the brake air tank, control pressure will be dumped and the brakes will engage fully.

If the sprayer e.g. must be moved, the load apportioning valve must be set. Remember to reset the handle to brake position again afterwards.

Position State Use

1 Relieved Move sprayer with air in the tank and without the air hose(s)

connected to the tractor. Disengages the brakes.

2 Full Use when driving with full tank.

3 Half full* Use when driving with tank half full.

4 Empty Use when driving with empty tank.

*If axle load exceeds 5250 kg. position 2 is required to be used.

ATTENTION! When parking the sprayer, always engage the parking brake, as the air brakes will only be engaged as



long as there is air in the tank! Cover the couplings with the dust flaps when hoses are disconnected.

ATTENTION! The load apportioning valve must be set at the position corresponding to the load on the trailer, for



obtaining optimal air pressure to the trailer brakes.

WARNING! Driving with wrong load apportioning valve setting, will make the brakes under or over apply, which can

cause hazardous situations.

Single-line brakes (optional)

1. Flip the snap coupler protection flap away.

2. Connect the snap coupler to the tractor outlet (black).

3. Let the compressor fill the sprayer’s air reservoir.

4. Check brake circuit for leaks.

5 - Operation

Liquid system

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 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.

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

Filling through tank lid

Water is filled into the tank by removing the tank lid located at front of the sprayer tank which is accessible from the platform. 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 siphoned back and contaminate the water supply lines, plant and 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 meter to avoid spillage by over-filling. Follow local legislation

in force at any time.

Filling of rinsing tank

The rinsing tank is filled via the 1” threaded connection piece at the valve system:

1. Remove the filler cap, then fit the external water hose to the threaded connection piece.

2. Engage external water pump, if any.

3. Keep an eye on the level indicator in order not to overfill the tank.

4. Stop filling and refit the cap.

Capacity: approximately 450 litres.

ATTENTION! Only fill rinsing tank with clean water! To avoid algae developing in the rinsing tank always drain the



rinsing tank if the sprayer is not in use for a longer period of time.

ATTENTION! For cleaning purposes etc. the rinsing tank is also accessible via the tank lid on top of tank.



Filling of clean water tank

To fill the clean water tank:

1. Remove the tank lid

2. Fill with clean water

3. Reposition the tank lid.

For use of water:

• Turn the ball valve lever to open. The ball valve is located on the valve cover.

The water from this tank is for hand washing, cleaning of clogged nozzles etc. Only fill the clean water tank with clean water from the well.

WARNING! Although the clean water tank is only filled with clean water, this water must NOT be used for drinking.

2. Close the agitation valve, turn pressure SmartValve to “Main tank”.

3. Engage diaphragm pump and set P.T.O. revolutions at 540 r/min or

1000 r/min depending on pump model.

4. Turn handle on External Filling Device valve towards Filling Device.

5. The tank is now filled with water. Keep an eye on the liquid level

indicator.

6. Turn handle on Suction Manifold away from Filling Device to discontinue filling process. Then disengage pump.

7. Disconnect suction tube and replace cover.

DANGER! Avoid contamination or personal injury. Do not open suction valve towards Suction Filling Device unless

€

pump is running and filling hose is connected. If this valve is opened without pump running, liquid will stream out of the coupler.

WARNING! Do not leave the sprayer whilst filling the tank and keep an eye on the level indicator in order NOT to

overfill the tank.

WARNING! If suction hose/filter is carried on the sprayer during spraying, it can be contaminated by spray drift which

will be transferred to lake/river when filling!

ATTENTION! Observe local legislation regarding use of filling device. In some areas it is prohibited to fill from open



water reservoirs (lakes, rivers etc.). It is strongly recommended only to fill from closed reservoirs (mobile water tanks etc.) to avoid contamination.

Safety precautions - crop protection chemicals

Always be careful when working with crop protection chemicals!

WARNING! Always wear proper protective clothing before handling chemicals!

Personal protection

Depending on chemical type, protective gear/equipment should be worn to avoid contact with the chemicals, e.g.:

• Gloves

• Waterproof boots

• Headgear

• Respirator

• Safety goggles

• Chemical resistant overall

WARNING! Protective clothing/equipment should be used when preparing the spray liquid, during the spray job and

when cleaning the sprayer. Follow the chemical manufacturer’s instructions given on the chemical label and/or local legislation.

WARNING! It is always advisable to have clean water available, especially when filling the sprayer with the chemical.

WARNING! Always clean the sprayer carefully and immediately after use.

WARNING! Only mix chemicals in the tank according to directions given by the chemical manufacturer.

WARNING! Always clean the sprayer before changing to another chemical.

Filling chemicals through tank lid

The chemicals are filled through the tank lid - Note instructions on the chemical container!

WARNING! Be careful not to slip or splash chemicals when carrying chemicals up to the tank lid!

ATTENTION! Due to risk of spillage and spot contamination it is not allowed in several countries to fill chemicals



directly through the tank lid. Use the TurboFiller for all induction of chemicals instead.

1. Make sure the spray control unit is switched off.

2. Set suction valve towards “Suction from main tank”, Agitation valve

towards “Agitation”. Other valves should be closed or turned to unused function.

3. Engage the pump and set P.T.O. revolutions to 540 r/min or 1000 r/min depending on pump model.

4. Add the chemicals through the main tank hole.

5. When the spray liquid is well mixed, turn handle on the pressure

SmartValve towards “Spraying” position. Keep P.T.O. engaged so the spray liquid is continuously agitated until it has been sprayed on the crop.

DANGER! Before turning Pressure SmartValve to “Pressure draining/TurboFiller” it is very important to be sure that the

€

quick coupler lid is correct and completely mounted to the filling stud into its locked position. Failure to do so may cause risk of contamination and injury from quick coupler lid being “shot” off when pressurized! If not possible to mount lid completely, lubricate the rubber seal and the grip hooks.

NOTE! Local legislation may not allow filling through the tank lid, but will require use of the chemical inductor instead.

1. Close TurboFiller lid.

2. Turn the suction SmartValve towards “Rinsing tank” or “External Filling Device” if clean water is available here.

3. Simultaneously press the Chemical Container Cleaning lever and the TurboFiller suction valve. This rinses the hopper

with the flushing nozzle while the rinsing liquid is emptied out of the TurboFiller.

4. Rinse the hopper for 30-40 seconds.

5. Open the lid to inspect if the TurboFiller is empty. If not, close the lid again and press the TurboFiller suction valve until

the TurboFiller is empty.

6. After the last flushing the TurboFiller suction valve must be open for at least 20 seconds after the rinse water is no longer visible in the hopper in order to completely empty the transfer hoses into the main tank.

ATTENTION! The TurboFiller needs to be cleaned thoroughly after finishing spraying again to be sure it is clean before



spraying other crops that may be sensitive to the chemicals just used. See section “Cleaning” on page 72 for details.

Operating the control units while spraying

The control units control the following spray functions:

1. Power ON/OFF/status LED. LED must be ON.

2. Automatic spray pressure regulation.

The regulation valve controls the main spray pressure. This is default selection when the controller is powered ON, and it should remain here during normal spraying.

3. Manual spray pressure regulation. Under normal spraying these should not be used as the regulation valve does this automatically.

4. Foam marker blob interval. Regulates the blob interval for the optional foam marker.

5. Foam marker (Left/Right). Turns the optional foam marker ON for each side.

6. Optional function (A/B). If extra equipment is added, it can be controlled from here.

A. Power ON/OFF/status LED. LED must be ON.

B. Section valves. Turns single sections on or off. Lever up is OFF and

down is ON.

5 - Operation

C. Main valve ON/OFF.

Use when spraying

• On the sprayer, turn the suction valve toward “Suction from Main tank” and the pressure SmartValve toward “Spraying”. Turn the agitation valve to “Agitation” if necessary.

• In order to close the entire boom, switch main ON/OFF (C) to OFF position. This returns the pump output to the tank through the return system. The diaphragm Non-drip valves ensure instantaneous closing of all nozzles.

• In order to close one or more sections of the boom, switch the relevant distribution valve (B) to OFF position (upwards). The pressure equalisation ensures that the pressure does not rise in the sections that remain open.

NOTE! For checking the volume application rate, please refer to the spray controller instruction book.

5 - Operation

Before returning to refill the sprayer

If the sprayer is to be refilled at the farm or at a fixed filling place without a filling space with hard surface and drain to closed reservoir, the sprayer should be rinsed before returning to refill.

Dilute the residues of the spraying circuit, and spray it on the crop. Then rinse the sprayer on the outside with the External Cleaning Device before returning to the farm.

WARNING! Always follow local legislation in force at any time.

Agitation before resuming a spray job

If a spray job has been interrupted for a while, severe sedimentation may occur depending on the chemicals being used. Before resuming the spray job, it might be necessary to agitate sediment material.

1. Turn the handle at the suction valve towards “Suction from main tank”. Turn the pressure SmartValve towards “Pressure draining/TurboFiller” and turn the Agitation valve towards “Agitation”. Other valves closed.

2. Engage the pump and set P.T.O. speed at 540 r/min or 1000 r/min (depending on pump model).

3. Agitation has started and should be continued for at least 10 minutes.

4. The spray job can now be resumed. Turn pressure SmartValve towards “Spraying” and start spraying.

DANGER! Before turning Pressure SmartValve to “Pressure draining/TurboFiller” it is very important to be sure that the

€

Parking the sprayer

To avoid spot contamination the sprayer should always be parked at either the washing/filling place or under roof. This avoid rainfall to flush down chemical residues from the sprayer's surfaces.

• Parking at the washing/filling location will retain residues.

• Always park the machine out of reach of children, animals or unauthorized persons.

Quick reference - Operation

In the following diagrams handle positions for different options are described.

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.

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, then for safety reasons please leave the job to your HARDI dealer’s workshop.

ATTENTION!



Clean sprayers are safe sprayers.

Clean sprayers are ready for action.

Clean sprayers cannot be damaged by pesticides and their solvents.

Guidelines

1. Read the whole chemical label. Take note of any particular instructions regarding recommended protective clothing, deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures are given, follow them closely.

2. Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods, etc. Contact the appropriate authority if you are in doubt.

3. 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, water courses, 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 62.

4. Cleaning starts with the calibration, as a well calibrated sprayer will ensure 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. It is strongly advised to perform an internal cleaning of the sprayer when high concentration 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.

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.

8. The sprayer must always be parked under roo f to avoid rain washing off pes ticide s and 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 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

components is the suction filter. Check it regularly.

Use of rinsing tank and rinsing nozzles

The incorporated rinsing tank can be used for three different purposes:

A. Full internal rinsing or cleaning.

B. External cleaning (can only be carried out on completion of “A”).

C. Rinsing spray circuit without diluting main tank content.

ATTENTION! The cleaning procedures stated requires the TurboFiller to be cleaned on beforehand (directly after the



last chemical filling). If the TurboFiller for some reason is not cleaned please carry out this cleaning before attempting the cleaning procedures A, B or C - see “TurboFiller rinsing” on page 68. Note that this cleaning will then use water from the rinsing tank reducing the available quantity for cleaning procedures A, B or C.

ATTENTION! Do NOT fill any cleaning detergents into the rinsing tank. If cleaning agents are to be used this should



be added the main tank.

A. Full internal rinsing

In-field diluting of remaining spray liquid residues in the spraying circuit for spraying the liquid in the field, before cleaning the sprayer.

NOTE! This rinsing is adequate/sufficient when the sprayer is going to be used again shortly (E.g. next day) in same or

similar crops (No risk by cross contamination and subsequent crop damages).

WARNING! If the next crop to be sprayed is sensitive to the latest chemical used a full cleaning should be carried out.

See “Full internal cleaning (Soak wash)” on page 76.

WARNING! Never clean the sprayer if there are risks of contamination of surface or underground water! Choose a

different spot for cleaning every time to avoid spot contamination to build up.

DANGER! Before commencing this rinsing procedure ensure that the blind cap is securely fitted and tightened on the

€

PressureEmpty quick-coupler! If this is not fitted and tightened properly it may burst off during the rinsing process and lead to personal injuries to the operator or persons in proximity of the machine!

This rinsing procedure will rinse the spraying circuit and main tank as follows:

1. Empty the sprayer as much as possible. Close the agitation valve (no agitation). Allow the pump to run for at least 1 minute after the liquid fan from the nozzles has collapsed to ensure that all relevant liquid has been expelled.

2. Turn suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Main tank”. Set agitation valve to “Full agitation”.

3. Engage and set the pump at approximately 300 rpm.

4. Use 1/6 (approximately 75 l) of the rinsing tank content at this valve setting.

5. Turn the pressure SmartValve towards “Pressure Empty/TurboFiller” for minimum 3 seconds to burst and flush the

safety valve. The TurboFiller is not flushed by this operation.

6. Turn the agitation valve towards “FastFiller flushing” and use another 1/6 (approximately 75 l) of the rinsing tank content for flushing the FastFiller lines.

5 - Operation

7. Shut off all nozzles by the main ON/OFF button on the grip.

8. Turn suction SmartValve towards “Main tank” and the pressure SmartValve towards “Spraying”. Engage the auxiliary

pump (FlexCapacity configurations only). Set the spraying pressure at 3-5 bar. If the pressure is set outside this range the rinsing result may be insufficient.

9. Allow the rinsing water in the main tank to circulate for minimum 45 seconds with the nozzles shut to flush the return lines from boom to tank.

10. Open all nozzles and spray the rinsing water from the main tank through the nozzles while driving in the field. Choose a different location each time to distribute the rinsing water over larger areas. Continue until all fluid is expelled from the boom tubes and nozzle - this may take several minutes after the spray fan has collapsed.

11. Shut off all nozzles by the main ON/OFF switch.

12. Turn the suction SmartValve towards “Rinsing tank” and the pressure SmartValve on “Tank rinsing”. Use another 1/6

(approximately 75 l) for this. The tank strainer should be removed to avoid shading for the rinsing nozzle.

13. Turn the suction SmartValve towards “Main tank” and the pressure SmartValve towards “Spraying”. With the nozzles shut allow the liquid to circulate for minimum 30 seconds to flush the return lines from boom to tank.

14. Open all nozzles by the main ON/OFF switch and spray the rinsing water from the main tank through the nozzles until all liquid is expelled from the boom tubes/nozzles.

15. Repeat step 11-14 another 3 times using 1/6 (approximately 75 l) of the rinsing tank content in each of the 3 sequences until the rinsing tank is empty.

16. Shut off the nozzles at the main ON/OFF button once the rinsing process is complete.

B. External cleaning

This procedure is used to rinse the sprayer on the outside in the field as required with the External Cleaning Device.

NOTE! Before attempting an external rinsing, make sure the main tank is rinsed (see “A. Full internal rinsing” on

page 74) and empty! Any liquid left in the main tank will be mixed with the clean water for external rinsing!

NOTE! Approximately 100 l of clean water in the rinsing tank will allow approximately 15 minutes of rinsing (Cleaning

nozzle consumption is 6 l/min at 10 bar pressure).

WARNING! Never clean the sprayer if there are risks of contamination of surface or underground water! Choose a

different spot for cleaning every time to avoid spot contamination to build up.

1. Engage pump at approximately 300 r.p.m. or 560 r.p.m. depending on pump model.

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

DANGER! Before turning Pressure SmartValve to “Pressure

€

draining/TurboFiller” it is very important to be sure that the quick coupler lid is correct and completely mounted to the filling stud into its locked position. Failure to do so may cause risk of contamination and injury from quick coupler lid being “shot” off when pressurized! If not possible to mount lid completely, lubricate the rubber seal and the grip hooks.

Rinsing of the liquid system

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

NOTE! The main ON/OFF on the Grip must be ON. Closing the main ON/OFF will transfer the rinse water back to the

main tank!

2. Close agitation valve (no agitation).

3. Turn off the Cyclone Filter Boost Valve to avoid dilution of main tank content.

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

water.

5. Disengage the pump again.

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.

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 recommended.



Full internal cleaning (Soak wash)

NOTE! This cleaning procedure is always used when:

A. The next crop to be sprayed is at risk to be damaged by the chemical just used, or

5 - Operation

B. The sprayer is not going to be used again for same chemical or crop right away, or

C. Before any repair or maintenance job is going to be carried out on the sprayer.

NOTE! Wash of sprayer between jobs with incompatible crops must be done according to prescriptions from the

chemical producer. Use e.g. AllClearExtra, as this is a commonly used cleaning agent. If your chemical prescribes another cleaning agent and/or another cleaning procedure, you must follow that.

Procedure for wash with a cleaning agent, e.g. AllClearExtra:

1. Rinse the sprayer in the field (See chapter “Use of rinsing tank and rinsing nozzles” subchapter A).

2. Drive to farm fill station.

3. Prepare sprayer for cleaning with cleaning agent, e.g. AllClearExtra. Fill water in the main tank to 10% of capacity

(respectively 330 litres, 450 litres, 550 litres and 700 litres). Fill the rinsing tank completely. This water is used later for rinsing.

4. Turn suction SmartValve towards “Main tank” and pressure SmartValve towards “Main tank”. Set agitation valve to “Full agitation”.

5. Engage and set the pump at approximately 300 r.p.m. Engage auxiliary pump (FlexCapacity configurations only).

6. Allow the liquid to circulate for 3 minutes.

7. Turn the pressure SmartValve towards “Pressure Empty/TurboFiller” for minimum 10 seconds without activating the

TurboFiller in order to burst and flush the safety valve.

8. Open the TurboFiller transfer valve and the deflector valve and allow liquid to circulate for 3 minutes.

9. Close the lid and activate the container rinsing valve to clean the hopper inside.

10. Shut off all three valves on the TurboFiller again.

11. Turn the agitation valve towards “FastFiller flushing” for 3 minutes to clean the FastFiller lines.

12. Verify that all nozzles are shut at the main ON/OFF button on the grip.

13. Turn the pressure SmartValve towards “Spraying”.

14. Allow the liquid in the main tank to circulate for minimum 3 minutes with the nozzles shut to clean the return lines

from boom to tank.

15. Turn the pressure SmartValve towards “Tank cleaning nozzles” and circulate liquid for further 3 minutes.

16. Spray out water with cleaning agent and chemical residue. Set the spray pressure at 3-5 bar. Note that the washing

water still contains active chemical and choose an appropriate area to spray out this. Alternatively the washings can be dumped at the Filling/washing location and retained in an appropriate receptacle (E.g. slurry tank or similar) - see section “Filling/washing location requirements”. Spot contamination and accumulation must be avoided. Continue to spray until all liquid is expelled from the boom tubes and nozzles.

17. Shut off all nozzles by the main ON/OFF switch.

18. Rinse the sprayer again with clean water to rinse out all remains of the cleaning agent. See section “Use of rinsing tank

and rinsing nozzles” subchapter A. “Full internal rinsing” This to avoid that the cleaning agent remains in the fluid system. Remains could damage the next spray chemical filled into the main tank.

19. Include rinsing of the TurboFiller in step 17. Operate all 3 valves during this process.

20. Dismantle all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and

detergent.

ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Clean manually with a high



pressure cleaner afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed afterwards!

NOTE! It is the responsibility of the sprayer operator or owner that the sprayer is cleaned sufficiently to avoid

contamination of the environment, crop damages and health & safety hazards to operator and the public. HARDI cannot be held responsible for any damages or incidents related to insufficient cleaning.

5 - Operation

PrimeFlow - manual cleaning

in the event of a AutoWash failure machines equipped with PrimeFlow can follow the same manual washing procedure as described in this manual when the following detail is observed:

• Open all nozzles before flushing the boom spray lines to avoid chemical residues from the boom lines are returned into the main tank.

Use of detergents

It is recommended to use an appropriate cleaning detergent suitable for cleaning agricultural sprayers.

• The cleaning detergents which contains a suitable lube or conditioner is recommended.

• If for some reasons this is not available and e.g. triple ammonia water is used, it is important to rinse the circuit

immediately after and add some lubricant to the rinsing water to avoid e.g. ball valves seizing up.

• Use of automotive antifreeze/radiator coolant (ethylene glycol) will protect the valves, seals etc. from drying or seizing up.

Techni c al re s idue

Inevitably a quantity of spray liquid will remain in the system. It cannot be sprayed properly on the crop, as the pump takes 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 the pressure gauge is read. See “Technical residue” on page 116 for specific technical residues.

The residues in the tank should be diluted immediately in the relationship 1:10 with water and afterwards be sprayed to 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. It is to be made certain however that the liquid in the spray lines are in unchanged concentration. Therefore there should be an untreated patch available to spray this out.

Using the drain valve

The drain valve is operated from platform just beside the main tank lid.

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.

If draining residues, e.g. liquid fertilizer into a reservoir, a snap-coupler with hose can rapidly be connected to the drain valve and the liquid safely drained.

5 - Operation

Pressure draining (optional)

It is possible to drain to an external tank. This is done the following way:

1. Connect a hose from an external tank to the pressure quick coupler on the sprayer.

2. Turn the Pressure SmartValve towards “External tank”.

3. Turn the suction valve towards “Main tank”.

4. Engage the P.T.O to start the pump.

5. When tank is drained then turn off P.T.O. again.

6. Disconnect hose and refit the quick coupler lid.

DANGER! Before turning Pressure SmartValve to “Pressure draining/TurboFiller” it is very important to be sure that the

€

quick coupler is correct and completely mounted to the filling stud into its locked position. Failure to do so may cause risk of contamination and injury from quick coupler being “shot” off when pressurized! If not possible to mount coupler completely, lubricate the rubber seal and the grip hooks.
