Use of the mist blower

The HARDI mist blower is designed for applying chemical products used for crop protection. This equipment may only be used for this purpose. The use of this equipment for other purposes is not allowed. If there is no special law in your region which obliges the user to have a permit, it is recommended to be well-prepared for protecting crops in a correct way and for handling chemical products safely so as to avoid unnecessary risks to people and the environment while spraying takes place.

For environmental issues the air kit is oﬀ ered with option to close either left or right side of the air stream from the blower. These blinds, are mandatory in some sensitive areas, to avoid chemical contaminated air, blowing towards river sides and water channels

Roadworthiness

When driving on public roads and other places where the road safety code or where there are other special rules and regulations for marking and lights on machinery, the machine must be equipped to comply with these regulations.

ATTENTION! For models not ﬁ tted with brakes the maximum speed is 25 km/h and 40 km/h for those with. This could vary according to local legislation. Contact your local authorities to ﬁ nd out the current maximum speed limits.

Identiﬁ cation plate

The identiﬁ cation plate is located on the front right-hand side of the machine and is riveted to the chassis. It indicates the make, model, serial number, and date of manufacture.

The serial number is also engraved onto the chassis. The number is found above the identiﬁ cation plate, as indicated in the picture. The serial number consist of ﬁ ve digits.

Chassis

The monoblock cold-pressed metal chassis is highly durable and built to last under everyday use under extreme conditions. It is manufactured using only the most advanced laser cutting and automated soldering processes. To protect against corrosion it is coated with a polyurethane bi-component paint on top of a highly adherent, steel blasted base.

3 - Description

Tank

The main tank made of impact-proof, UV-resistant and chemical resistant polyethylene has a purposeful design with no sharp corners for easy cleaning. Nominal contents are 1000, 1500, 2000 or 3000 l. A large, easy to read tank contents indicator is placed on the front - right-hand side and another one is placed on the left side. First one is visible from the tractor cabin. The ﬁ lling hole is accessible from the left-hand side. This ensures an easy access for the ﬁ lling of spray liquid, cleaning of the tank, etc. The mistblower is equipped with a clean water tank integrated with the main tank design.

3 - Description

Liquid system

General information

All the suction system functions are operated via a 3-way valve. The pressure valve is also to be found in the pressure circuit. The low pressure circuit is called HLC (Hardi Liquid Circuit).

The liquid circuit

Consist of manifold system in the working zone (front part) where pressure manifold receives liquid from the pump, and distributes to the diﬀ erent options on the sprayer – to the operating unit, to the TurboFiller, to the bottle cleaner, to the Powder mixer in strainer etc., all according to conﬁ guration of options. The suction manifold in same area allows suction from main tank, rinsing tank or external water source, if ﬁ tted, depending on its conﬁ guration.

The pressure side of the liquid circuit is ﬁ tted with a safety valve to protect the circuit against misuse of excessive pressure. See chapter “Safety valve”

Diaphragm pump

Pumps with a diaphragm: Models 321/10 (max. 20 bar) or 363/7 (max. 20 bar)

They are low pressure and robustly built. Use only grease for lubrication. The 363 model has six diaphragms and the 321 has two. This type of pump is self-priming, works without oil and can run dry as long as necessary.

Valves

The suction valve is located above the pump and is used to select where to suck liquid from. Either suction from the main tank for spraying or from the rinse tank for internal cleaning of the liquid circuit. The function is selected by turning the handle of the valve towards the desired function.

ATTENTION! If one of the handles is too tight - or too loose (=liquid loss) - the valve needs to be serviced. For more information, see section on “Maintenance”.

Valves and symbols

The valves are identiﬁ ed by coloured discs ﬁ tted on the valves themselves. The symbols correspond to the optional accessories, and are located on the discs for quick identiﬁ cation and handling. To activate/open a function, turn the lever to the desired function.

ATTENTION: Only the functions to be used should be activated – the other valves should always be kept closed.

ATTENTION: If the handle of a MANIFOLD valve is too tight – or too loose (loss of ﬂ uid)– the valve needs to be serviced. For more information, see the section on ‘Maintenance’.

3 - Description

Manifold system

The functions of the spray circuit are operated via the centrally situated MANIFOLD with colour coded plates and pictorial symbols for easy operation.

The modular valve system facilitates the addition of optional extras on both pressure (A) and suction (B) for agitation and for rinsing nozzle (optional equipment).

Blue valve – Blue disc = Return valve

Towards agitation Towards the suction pump

The position of the return MANIFOLD valve determines where the excess ﬂ ow from the ﬂ uid circuit goes. When the arrow on the handle points to a symbol, the excess ﬂ uid will be fully sent towards that function (the example shows agitation). This valve does not have the ‘0’ position.

Safety valve

It is made of cast iron and is situated at the front of the machine next to the operating unit. From this manifold it is possible to activate the agitator and the rinsing nozzle for internal cleaning (optional), as well as the Turboﬁ ller (optional) or powder mixer. Do only open the manifold valve in order to send pressure to the desired device, as in the example given: the Turboﬁ ller.

Pressure manifold

It is made of plastic and is situated on the front of the machine next to the operating unit. From this manifold it is possible to activate the agitator and the rinsing nozzle for internal cleaning (optional).

MAX. 20 bar (HLC)

MAX. 40 bar (HPC)

Suction and pressure pulsation dampers

The 321 pump is ﬁ tted with a pulsation damper on suction and pressure sides. The pressure side damper is pressurized. The dampers will reduce pulsations and secure an even ﬂ ow from the pump.

Axial blower units

Technical information

The air kits ﬁ tted on the HARDI ZATURN mist blowers are the AG820 and AG920, both having a polyethylene housing and fan blades made of a hardened synthetic material. Their aerodynamic shape oﬀ er a high quantity and perfect air distribution, low noise levels and low power consumption when adjusted to standard levels. The fan clutch enables a smooth start and stop.

EF820, EF920, AB750, AB820, AB920, AG820, AG920, IAG820, IAG920, SF65, SF85 and XF90

The air kits are ﬁ tted with a grid with air guides at the air intake, which forms the air ﬂ ow before reaching the fan, to decrease the imbalance in the airﬂ ow. The fan is either 820 or 920 mm of diameter and is ﬁ tted with blades made of a hardened synthetic material. This reduces the power consumption to a minimum as a result of low material density.

There is a channel between the air intake and the cone of the air kit which increases the air speed through the outlet, and ensures that a high uniformity in air distribution is achieved.

Pneumatic spray system

3 - Description

The high air speed in the spout breaks the spray liquid and gives a very ﬁ ne mist together with turbulence. Using the deﬂ ectors at the spout outlet permits the mist to be distributed uniformly.

There are four spout models, which can be combined according to the bar type and assembly requested for the machine:

A. Cannon with 1 atomizer

B. Spout with 2 atomizers

C. Spout with 3 atomizers

D. Spout with 4 atomizers

The Paraﬂ ow pneumatic system is low pressure. This system takes advantage of the high air speed at the pipe outlet to break the spray liquid and give a very ﬁ ne mist together with turbulence. Using the deﬂ ectors at the tube outlet means that the liquid is distributed uniformly.

There are two Paraﬂ ow models, which cannot be used together, according to the bar type and assembly requested for the machinery:

Paraﬂ ow tube with 4 in-line atomizers

Paraﬂ ow tube with 6 in-line atomizers

ATTENTION! Ceramic nozzles are used for the standard pneumatic system and the paraﬂ ow system. This type of nozzle has two positions. If the nozzle is ﬁ tted so that the ﬂ ow enters on the ﬂ at side, less ﬂ ow will be allowed than on the conical side.

Hydropneumatic spray system

The hydropneumatic system is medium-high pressure. This system takes advantage of higher turbulence in the low-volume conical nozzle and sprays the liquid with an even distribution. The air reaches high speed in the spout, spraying the liquid in a fan.

There are three spout models with three or ﬁ ve nozzles. These two models cannot be combined.

E. Spout with 3 nozzles.

F. Spout with 5 nozzles.

Where not all the nozzles are required in treating the crop, the nozzles can be replaced for caps.

3 - Description

IRIS system, continuation of Hydro pneumatic system

The IRIS application system allows individual air adjustment as each outlet permits steep angling or even closing of the air supply, if necessary. The IRIS system provides the required droplet size and air conduction to the target. The most delicate and diﬃ cult part of the vine, the grape cluster, is safely treated throughout the season, due to a very easy and quick calibration with the IRIS system.

A. Non-drip valve

B. Nozzle

C. Vane position indicator (angle)

D. Air vane adjustment

E. Air vanes

General information

Unloading the mistblower from the truck

When loading or unloading the mistblower to/from a lorry by using a lever and pulley or a crane, use the suspension points shown on the diagram and make sure the straps used are strong enough.

DANGER! Nobody must stand below or next to the machine during loading or unloading.

4 - Starting up

Before starting up for the ﬁ rst time

Although the surface of the metallic parts of the mist blower have been coated with a strong, protective product, we recommend you to apply a layer of anti-corrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) to all metal parts to avoid chemical products from discolouring the enamel, as well as to ease future cleaning.

ATTENTION! This treatment should be carried out whenever the protective layer wears oﬀ .

Counterweights

Check if it is necessary to place a counterweight on the front of the tractor, to increase the stability and steering performance.

4 - Starting up

Mechanical connections

Adjusting the drawbar length

1. Place the jockey wheel in the position indicated on the photo.

2. Loosen the three bolts (A), located in the area where the drawbar is connected to the chassis.

3. Remove the bolt (B).

4. Adjust the drawbar to the desired position.

5. Replace bolt (B), making sure that it passes through the holes in the chassis and the shaft.

6. Tighten the bolts (A) and the locknut again.

Jockey wheel

The jockey wheel allows the mistblower to be coupled to or uncoupled from the tractor. The illustration shows the position when the mistblower is detached from the tractor; when the mistblower is attached it will be stored on the left-hand side of the mistblower chassis using two pins.

The height of the machine can be adjusted by turning the handle (C).

Connecting the fork drawbar

This is attached to the transversal hole boom mounted on the tractor lower links. Before connecting the PTO make sure that the coupler is correctly attached and secured, and that the tractor wheels do not touch the mistblower when turning. A transmission shaft with CV joint is not required.

Adjust the drawbar if necessary as explained in another section.

Connecting the ring drawbar

This is attached to the standard clevis-type coupler close to the tractor body. Before connecting the PTO make sure that the drawbar is correctly attached and secured, and that the tractor wheels do not touch the mistblower when turning. A transmission shaft with CV joint is required on the tractor’s side. It is possible to adjust the length of the drawbar.

Adjust the drawbar if necessary as explained before.

Connecting the articulated drawbars

This is attached to the tractors lower linkage arms. Before connecting the PTO make sure that the diameter of the pins matches the ball diameter on the lower links, that the snap locks are engaged and check that the tractor wheels do not touch the mistblower when turning.

Of the three hitch types this is the one that permits the tightest turns, but a transmission shaft with CV joint is then required on the mistblowers power intake side. The length of the drawbar is adjustable.

Adjust the drawbar if necessary as explained on page 35.

Lock device on turnable drawbar

The turnable drawbars are ﬁ tted with a lock device, once down in forward and horizontal position; the pivoting eﬀ ect is very limited. If the tractor has a weight 2 X the sprayer, it can be used in hilly conditions, where risk of tumbling the sprayer exists, but it is recommended to use the drawbar unlocked.

4 - Starting up

Coupling the driveshaft

Initial installation of the driveshaft may involve having to cut the axle to adapt it to the tractor to which it will be hitched. To hitch it for the ﬁ rst time, proceed as follows:

1. Attach the mistblower to the tractor in such a way that the distance between the PTO shaft and the mistblower pump is the shortest possible.

2. Stop the engine and remove the ignition key.

3. If the driveshaft needs to be shortened, pull the two parts of the shaft apart. Fit the two parts of the shaft, one to the tractor and the other to the mistblower crankshaft and measure out the length that needs to be removed. Mark the protection guards.

ATTENTION! The shafts must always have a minimum overlap of one third of their working length.

4. Cut both parts equally, using a saw. File the proﬁ les afterwards to remove burrs.

5. Grease the proﬁ les and reassemble male ﬁ tting and female ﬁ tting.

6. Fit the shaft to the tractor PTO and to the mistblower pump shaft.

IRIS system setup

The IRIS application system is standard equipped with ceramic hollow cone nozzles. Each drop leg holds 8 nozzles per drop leg. If a curtain area of the canopy is not meant to be sprayed, a small valve is ﬁ tted as per two nozzles that allow turning of the spray mist. If only one nozzle is needed in that area it is as well possible to ﬁ t a blind cap.

4 - Starting up

In the valve A that allows the spray mist to pass on the nozzle, there is a small no drip valve that secures when the main switch turns of the spray mist, that all nozzles stops instantly, and do not spill on the ground.

The nozzles B are ﬁ tted in an adjustable support, in order to angle them forward accordingly to forward speed, and there by not loosing spray mist behind the sprayer.

The air outlet has an indicator C that shows the angling of the air blade E which are adjusted by pressing bottom D in, and then move up or down the vanes E.

The air outlet in the lower part shall be orientated upwards to get the spray mist penetrating from down and upwards. The upper spout shall point downward in order to avoid drift. Those setting are accordingly to grot hog the canopy, and adjustment is necessary during the season, as the size of the canopy change.

In order to get the optimal cross ﬂ ow eﬀ ect and penetrate the canopy the IRIS drop leg shall be set 10º , 15º , 20º or 30º forward, as indicated in the adjustable part in the top of the drop leg. The forward angling is set accordingly to forward speed while spraying.

Blower unit

Safety information

The fan must not be in operation when driving on public roads. The nozzle opening function should never be used on public roads. Any failures could cause injury to people and animals or damage the crops

In the event that the machine needs to be in operation (agitation) while driving along public roads until reaching the ﬁ eld, make sure that the gearbox speed selector is switched to neutral position.

DANGER! If any unusual noise or excessive vibration in the air kit is detected then stop the equipment immediately and have it serviced by an authorised HARDI technician.

Selecting the gear

5 - Operation

The low or high gear can be selected using the specially designed lever.

On the rear, left-hand side of the machine the selection lever is accessed between the tank and fan A.

To change the speed, pull the lever outwards (A)and then move it up Or down as required. Lock the lever in the selected position (at the lid)

Bottom position: 1st gear or low speed (1).

Top position: 2nd gear or high speed (2).

Centre position: Neutral (0).

ATTENTION! Do never drive and fold booms at same time. Never maneuverer the sprayer unless the boom is 100% unfolded, otherwise the upright will be damaged.

When the boom is folded, it must rest on transport bracket

before driving.

5 - Operation

While moving the Sprayer

The booms must be 100% unfolded or resting in the transport bracket.

The boom must unfold, and stay ﬁ rmly, stiﬀ , not wobbly . If the boom is not held ﬁ rmly unfolded during spraying, it will auto destroy structure due to movements, caused from lack of ﬁ rm position.

See maintenance and starting up (Adjustment of hydraulic fold).

Secure folding cylinder is correctly adjusted, and eventually the stop positions / stop bolts, are adjusted correctly in order to secure that the boom stays rigid and ﬁ rm while working. To reinforce, eventually a trapeze or pendulum suspension can be activated, but it can’t be rigid, it must be movable and ﬂ oating.

Adjusting the fan A6820 and SF65/SF85 and XF90

The angle of the fan blades can be adjusted to 4 positions. The factory setting is pos. 3 (40º). Decreasing the angle of the blades (minimum angle, pos. 1 (30º)), reduces the air ﬂ ow and power consumption. Increasing the angle (maximum angle, pos. 4 (45º)), will increase the air ﬂ ow and power consumption. It allows the mist blower to be adapted to the diﬀ erent spray jobs and tractor sizes.

To change the angle of the fan blades you should follow these steps::

1. Loosen the Allen screws without taking them out completely.

2. Loosen the Allen screws whilst holding the nut at the back of the fan.

3. With both hands on opposite blades, turn them to the desired position between 1 and 4. All the blades should turn at the same time.

4. Finally, check that all the blades are in the correct position.

5. Tighten all the screws.

IMPORTANT The fan must be calibrated correctly after changing the pitch setting.

For technical details ask your dealer and factory.

5 - Operation

Single side blinds (Optional)

The air stream can be blocked to one side to prevent spray drift towards sensitive areas.

This is used when one section valve is shut during spraying along orchard edges, streams, open waters or other sensitive areas where spray drift must be kept away.

Loosen the nuts, slide the blind over the air outlet and tighten the nuts again.

ATTENTION! Only slide the blind of one side at the time. Never close both sides at the same time!

5 - Operation

Fluid circuit

Filling/washing location requirements

When ﬁ lling 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 mistblower is always ﬁ lled at the same place, a special ﬁ lling/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, 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 ﬁ lled in the ﬁ eld where the spraying is to take place. If so, choose a diﬀ erent location

for each reﬁ lling.

If no other requirements of distances exist, the ﬁ lling should not be established closer than:

1) 300 metres from public or non-public water supplies for drinking purposes and

2) 50 metres from surface water (watercourses, lakes and coastal waters), treatment sumps, cesspools of drainage

systems, and nature reserves.

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 with water

The tank should be ﬁ lled to a third of its capacity with clean water before. adding the chemical product. Always follow the instructions given on the product label!.

WARNING! If spray liquid is left in the tank, for safety reasons all valves must be shut.

5 - Operation

Filling through tank lid

The tank is ﬁ lled with water through the ﬁ lling hole by removing the lid located on the top of the tank. The water used should be as clean as possible to obtain best results.

Fill the tank using the ﬁ lter to prevent impurities from entering the tank. For greater ﬁ lling capacity, an overhead tank can be used.

DANGER! Do not place the ﬁ lling hose inside the tank. Keep it out of the tank at all times and only point it towards the ﬁ lling hole. If the pressure hose was placed inside the tank and there was a drop in water supply pressure, the chemical product could be syphoned back and contaminate the water supply lines, plant and well.

ATTENTION! The water supply line should be provided with a check valve as additional safety precaution. Follow local legislation in force at any time.

ATTENTION! The water supply should be provided with a meter to avoid spillage by over-ﬁ lling. Follow local legislation in force at any time.

Filling the rinsing tank

The rinsing tank is integrated with the main tank.

Capacity: 90 litres for 1000 and 1500 litres main tanks, and 130 litres for 2000 and 3000 litres main tanks.

The illustration shows the location of the rinse tank.

ATTENTION! ﬁ ll 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 long period of time.

Rinsing nozzle

This is located inside the main tank. When the nozzle is engaged it rotates fast and sprays clean water in all directions.

If the machine is ﬁ tted with a rinsing system, there is one rinsing nozzle in 1,000-litre tanks, and two rinsing nozzles 1,500, 2,000 and 3000 litre tanks.

5 - Operation

Filling the clean water tank

The clean water tank is located at the front and integrated in the main tank design. It is used for washing hands, gloves and cleaning clogged nozzles, etc.

WARNING! Although this tank is completely separate from the main tank and should only be ﬁ lled with clean water, this does not mean that the water is suitable for drinking.

Drain valve

The valve for safe draining is located on the underneath of the tank. To access it, you must crouch on the left side of the equipment, where the jockey wheel is attached to the chassis when the equipment is hitched to the tractor.

To empty the tank, pull the handle towards the valve. To ﬁ ll the tank again, pull the valve handle toward the front of the equipment and it will close.

WARNING! When opening the valve, take care to ensure that the liquid does not spill over your hands or feet.

To empty the residual liquid in a special tank or container for storage, the quick release A of the drain valve can be adapted to connect a hose with the ﬁ tting B so that liquid can be emptied safely.

G is 15 bar safety valve; it is important to open it once in a while, especially under cleaning process, to avoid chemical residues in the tubes connected.

Filling liquid chemicals by HARDI TurboFiller (optional)

1. Fill the main tank at least 1/3 with water (unless something diﬀ erent is stated on the chemical container label).

2. Turn the Manifold valve towards TurboFiller.

3. Set the fan gear lever to neutral position, engage the pump and set P.T.O. at 540 r/min.

4. Open TurboFiller lid. Measure the correct quantity of chemical and ﬁ ll in the hopper.

5. Engage the hopper transfer device by opening the TurboFiller suction valve so the chemical is being transferred to the main tank.

6. Engage the ﬂ ushing devise to ﬂ ush the hopper. If powder chemicals are ﬁ lled the ﬂ ushing device must be open before pouring the powder into the hopper.

5 - Operation

7. If the chemical container is empty, it can be rinsed by the Chemical Container Cleaning device. Place the container over the multi-hole nozzle and push the upper lever to the left of the TurboFiller.

8. Close TurboFiller suction valve when the hopper has been rinsed.

9. Close the TurboFiller lid.

10. Disconnect the pressure to the TuboFiller, and keep agitation activated to ensure homogeneous concentration.

11. Engage the fan gearbox before spraying..

DANGER! Always wear face shield and other appropriate personal safety equipment when ﬁ lling chemicals.

ATTENTION! The scale in the hopper can only be used if the sprayer is parked on level ground! It is recommended to use a measuring jug for best accuracy.

DANGER! In order to avoid spray liquid hitting the operator, do not press lever unless the multi-hole nozzle is covered by a container as spray liquid may otherwise hit the operator.

ATTENTION! The rinsing device uses spray liquid to rinse containers for concentrated chemicals. Always rinse the chemical containers with clean water several times until they are clean before disposal.

ATTENTION! The hopper rinsing device is using spray liquid for rinsing the hopper of concentrated chemicals! Cleaning the TurboFiller must always be done when the spray job is ended and together with the entire sprayer. A cleaning after the last ﬁ lling and before spraying the last tankful does not ensure a clean TurboFiller!

5 - Operation

TurboFiller rinsing

Rinsing the TurboFiller and chemical containers is done in the following two ways:

When TurboFiller lid is open

For cleaning empty containers: put container over the rotating ﬂ ushing nozzle in the middle of the TurboFiller so that the nozzle is inside the container. Press the Chemical Container Cleaning lever and the TurboFiller suction valve at the same time to activate the ﬂ ushing nozzle in the middle of the TurboFiller and empty out the TurboFiller rinsing liquid.

When TurboFiller lid is closed

Use the Chemical Container Cleaning lever to rinse the hopper after ﬁ lling of chemicals has ended. Press the Chemical Container Cleaning lever and the TurboFiller suction valve at the same time to activate the ﬂ ushing nozzle in the middle of the TurboFiller and empty out the TurboFiller rinsing liquid. Do this 3 times and after the last ﬂ ushing 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.

ATTENTION! The TurboFiller needs to be cleaned thoroughly after ﬁ nishing spraying again to be sure it is clean before spraying other crops that may be sensitive to the chemicals just used. See section Cleaning for details.

5 - Operation

As this manual does not refer to only one model, since HARDI oﬀ ers multiple conﬁ gurations of the same sprayer, the following chapter refers to the available operating units.

Power supply

Power requirement is 12V DC. Always note polarity! For proper function of the electric equipment, the wires must have the following recommended cross sectional areas and correct fuses to ensure a suﬃ cient power supply. The delivered power connectors follow the standard of most of the newest tractors. If you have a tractor with another power connector, it is necessary to disassemble the connector and ﬁ t it to the actual tractor connector. The number and the type of connectors may vary depending on the speciﬁ cations.

When 12 V power is taken from other places than the battery, it often changes in voltage when other power consumption is activated (Air condition on / oﬀ ventilator on the radiator on/ oﬀ etc.) That assistance in voltage does aﬀ ect the Spray Computer.

Installation of control unit brackets

Find a suitable place in the tractor cabin to mount the control units. Best recommended position is to the right of the driver seat.

The supplied tractor pillar bracket (A) has a hole spacing of 100 and 120 mm that ﬁ ts most tractors. Threaded mounting holes may be hidden behind the front corner cover. Check tractor instructions manual for information regarding attachment points. Three mounting tubes (B) are supplied. One, two or all three may be used. They can be bent and shortened. A spacer (C) is also supplied to allow further attachment possibilities. Find the best solution for your tractor or vehicle. Tube (B) plate is prepared so that, if correctly orientated, all boxes will line up.

DANGER! turn oﬀ any spray computer before you unplug the

power supply and cable to the sprayer.

Data transmission must stop, before power supply is stopped.

100-120 mm

5 - Operation

Adjusting the BK/2 Operating Unit

ATTENTION! It is very important that the operating unit is well adjusted. Before using the equipment for the ﬁ rst time, it is necessary to adjust the constant pressure valves at each section valve.

During this procedure, the individual return capacity of each section is adjusted, so that it returns the same amount of liquid that would normally be sprayed through all the nozzles at the section when open.

This avoids variations in pressure when one or both sections are shut. The adjustment procedure is the following:

1. Open both sections via the lever taps.

2. Set the pressure at, for example, 3 bar.

3. Close one of the Sections.

4. Adjust the constant pressure valve of the closed section valve until the pressure gauge indicates 3 bar again.

5. Open the section valve again and repeat this procedure for the other section valve.

6. Verify the adjustment by opening both sections at the same time or one by one. If the operating unit is correctly adjusted the pressure always remains unchanged.

ATTENTION! It is recommended to carry out this adjustment as close to the intended working pressure as possible.

ATTENTION! Carry out this adjustment every so often as somebody may accidentally change the position of the pressure equalisation valve

ATTENTION! once the pressure adjustment has been performed, it only needs readjustment when:

1. Another nozzle with a diﬀ erent capacity is used.

2. The nozzle output has increased due to wear.

MC/2 operating unit

This high-pressure manual operating unit is used in conﬁ gurations with piston or diaphragm pumps.

It consists of a pressure valve with a built-in pressure gauge.

To adjust the pressure, turn the black handle. To increase the pressure, turn the handle clockwise. To decrease pressure, turn it anti-clockwise.

The spray can be controlled from the tractor using the two remote levers.

Each lever controls one section valve. You can select one section, two sections or no sections open.

Cleaning

General information

In order to be able to use your mistblower for many years, a maintenance programme needs to be followed. This programme should include a comprehensive cleaning procedure.

ATTENTION! Always read the individual sections. Carefully read the maintenance task instructions before starting. If any part of these instructions is unclear, for safety reasons, please contact your HARDI dealer for further information.

ATTENTION! A clean mistblower is a safe mistblower.

A clean mistblower is always ready for action.

Clean mistblowers are not damaged by pesticides and their solvents.

Steps to follow

1. Fully read the chemical product’s label. Take note of any special instructions regarding protective clothing, deactivating agents, etc. Read the labels on the detergents and deactivating agents. If any cleaning procedure is speciﬁ ed, follow it accordingly.

2. Familiarise yourself with local legislation regarding the disposal of pesticides, mandatory decontamination methods, etc. Contact the appropriate department, e.g. Department of Agriculture.

3. Pesticide washings can usually be emptied out on a soakaway or retained at a washing location (See “Filling/ washing location requirements”). This must be an area not used for crop growing. You must avoid seepage or runoﬀ of residue into watercourses, wells, springs, pools, etc. The ﬂ uid remaining after rinsing the equipment cannot be disposed of down a sewer. It must be emptied into a suitable soakaway.

4. Cleaning starts with calibration. A properly calibrated mistblower ensures a minimal amount of ﬂ uid remaining.

Applying an anticorrosive wax or oil , makes next cleaning much easier, chemicals do not “burn” into the paint work and other surfaces.

5. It is good practice to clean the mistblower immediately after use, leaving it safe and ready for the next spray job. This prolongs the life of the parts.

6. At times, the spray liquid may need to be left in the tank for a short time e.g. overnight or until weather is suitable for spraying. Unauthorised persons or animals should not have access the mistblower under these circumstances.

7. If the product applied is corrosive, all metal parts of the machine before and after use should be coated with a suitable rust inhibitor, such anticorrosive wax or oil, as described under suitable lubricants.

Cleaning and maintaining the ﬁ lters

Clean ﬁ lters ensure:

1. Mistblower parts, such as the valves, diaphragms and operating units, are not blocked or damaged during use.

2. Nozzles are not blocked during spraying.

3. The pump has a long service life. A clogged suction ﬁ lter will result in pump cavitation. The main ﬁ lter that protects the mistblower parts is the suction ﬁ lter. Check it regularly.

ATTENTION! It is strongly recommended to pump antifreeze liquid, Glycol “through the entire circuit, move all manifolds valves; let the pressure safety valve pop..

No matter if the machine is in a warm clime, it simply conserves all synthetic part in the circuit.

5 - Operation

Cleaning the tank and liquid system

1. Dilute remaining spray liquid in the tank with at least 10 parts of water and spray the liquid out in the crop/orchard just sprayed.

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

3. Rinse and clean mistblower and tractor externally. Use detergent if necessary.

4. Remove tank and suction ﬁ lters and clean. Be careful not to damage the mesh. Replace suction ﬁ lter top. Replace ﬁ lters when the sprayer is completely clean.

5. With the pump running, rinse the inside of the tank. Don’t forget the tank roof. Rinse and operate all components and any equipment that have been in contact with the chemical. Before opening the distribution valves and spraying the liquid out, decide whether this should be done in the ﬁ eld again or on the soakaway.

6. After spraying the liquid out, stop the pump and ﬁ ll at least 1/5 of the tank with clean water. Note that some chemicals require the tank to be completely ﬁ lled. Add appropriate detergent and/or deactivating agent, e.g. washing soda or Triple ammonia.

7. Start the pump and operate all controls enabling the liquid to come into contact with all the components. Leave the distribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short period. Check the label.

8. Drain the tank and let the pump run dry. Rinse inside of the tank, again letting the pump run dry.

9. Stop the pump. If the pesticides used have a tendency to block nozzles and ﬁ lters, remove and clean them immediately.

10. Replace all the ﬁ lters and nozzles and store the mistblower. If, from previous experiences, it is noted that the solvents in the pesticide are particularly aggressive, store the sprayer with the tank lid open.

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 ﬁ eld 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.

Use of rinsing tank and rinsing nozzles (optional)

The incorporated rinsing tank can be used for two diﬀ erent purposes.

ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.

In-ﬁ eld diluting before cleaning

In-ﬁ eld diluting of remaining spray liquid residue in the spraying circuit, before cleaning the sprayer.

Rinsing the tank and liquid system

1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of all nozzles.

2. Turn suction valve towards “Rinsing tank” and pressure valve towards “Spraying”.

3. Engage and set the pump at approximately 300 r.p.m.

5 - Operation

4. When 1/3 of the contents in the rinsing tank is used, turn suction valve towards “Main tank” and operate all valves on the pressure side of the system in the following order so that all hoses and components are rinsed:

I. Turn the pressure valve towards TurboFiller (if ﬁ tted) and open the TurboFiller suction valve.

II. Open TurboDeﬂ ector valve and close it again when clean water comes out of nozzles.

III. Close TurboFiller lid and squeeze the Chemical Container Cleaning grip to clean this device.

IV. Open TurboFiller lid again and make sure that TurboFiller is empty.

V. When empty, close the TurboFiller suction valve again.

VI. Turn the suction valve towards “Main tank” and the pressure valve towards “Spraying” and spray the liquid in the

ﬁ eld just sprayed.

Cleaning of Main tank

5. Turn the suction valve towards “Rinsing tank” and the pressure valve towards “Internal Tank Rinsing”. Remove the ﬁ lling strainer to avoid any cleaning shadows behind it.

6. When another 1/6 of the contents in the rinsing tank is used, turn the suction valve towards “suction from Main tank”.

7. Turn pressure valve towards “Spraying” and spray the liquid in the crop/orchard just sprayed.

8. Repeat point 6 - 8 one more time.

WARNING! When critical chemicals have been used, before spraying another crop/orchard sensitive to the chemical just used or a cleaning detergent is recommended, do an extra cleaning:

9. Fill the rinse tank again.

10. Fill the main tank with 500 l clean water.

11. Add the cleaning detergent to the main tank by using the TurboFiller. Follow instructions on the label of the cleaning agent. Ask you chemical dealer for appropriated cleaning detergent, likewise deactivating agent as ALL CLEAR® EXTRA or washing soda (caustic soda ash), or Triple ammonia cleaning detergent.

12. Clean the whole system again.

13. To get the best cleaning eﬀ ect the Self-Cleaning Filter and the Suction Filter sieves should be washed with clean water.

14. Rinse the sprayer with clean water afterwards. Then mix in glycol / antifreeze liquid, or cooking oil diluted in water, to conserve liquid circuit.

ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually with a brush afterwards, especially if crops sensitive to the chemical just sprayed are to be sprayed afterwards!

Rinsing when main tank is not empty

Rinsing the pump, operating unit, spray lines, etc. in case of stop in spraying before main tank is empty (e.g. beginning rain etc.).

Cleaning of the liquid system:

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

2. Close AgitationValve (no agitation).

3. Engage the pump and spray the water from the rinsing tank in the ﬁ eld until all nozzle tubes/nozzles have been ﬂ ushed with clean water.

4. Disengage pump again.

5 - Operation

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 ﬁ eld just sprayed.

ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended.

6 - Maintenance

Lubrication

General information

Always store lubricants clean, dry and cool - preferably at a constant temperature - to avoid contamination from dirt and condensed water. Keep oil ﬁ lling 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.

6 - Maintenance

Filters and ﬁ ttings

Inspect the ﬁ lters every 50 working hours. Apart from ensuring that they are clean, make sure that the mesh is in good condition. Otherwise, the eﬃ ciency of the ﬁ lters will be reduced.

Whenever dismantling a ﬁ lter or hose pipe, take care not to pinch the o-rings ﬁ tted to them. When replacing the pipe ﬁ tting, lubricate the o-ring with oil or grease so it seats in the groove.

ATTENTION! If the ﬁ lter is not in good condition, it could cause numerous unnecessary interruptions during the working day, extending the working time required.

ATTENTION ! Each time you remove a ﬁ tting to check the condition of its o-ring or for any other reason, remember to lubricate the O-ring with oil or grease to prevent it from being pinched or breaking when reassembling the ﬁ tting in its housing.

ATTENTION! Insuﬃ cient greasing of the pump could cause it to overheat and break the moving parts inside.

Fork drawbar

Keep the moving parts greased through the grease nipple to avoid wear and seizing up.

Also grease the contact faces of fork and drawbar.

Ring drawbar

Keep the moving parts greased through the grease nipple to avoid wear and seizing up.

Also grease the contact faces of hitch ring and drawbar clevis.

Articulated drawbar

Keep the moving parts greased through the grease nipple to avoid wear and seizing up.

In the pivoting axle of the articulated drawbar a second grease nipple is to be greased.

Also grease the moving parts between pins and lower link balls.

The turnable drawbars, must be greased as per every 100 hours, through indicated grease nipples.

6 - Maintenance

ATTENTION! The turn stop welded to the ball prevents the equipment from performing too tight turns that could cause it to break. Do not force turns beyond this point as this may damage the drawbar parts.

DANGER! Always stop the PTO when taking very tight turns, even when using a transmission shaft with wide-angle CV joint. Tight turns with the PTO on may cause the CV or the pump crankshaft to break and cause major vibrations in the gearbox. This may lead to damages of the fan or air kit.

Axles with brake

The hub is the part of the axle that must be greased. Remove hub cap

(A) and grease the inside of the rotating head.

Where your machine is ﬁ tted with the axle with hydraulic brake, the moving part of the brake (B) must also be greased. Grease at least once a year.

6 - Maintenance

Bolt on the PTO to the pump.

Remember weekly PTO greasing / every 50 hours of the tank PTO.

WARNING!If the transmission shaft is not cleaned and lubricated as described it will not be able to extend or retract during operation when load is applied. This may overload the bearings on pump and gearbox or cause vibrations in the transmission and fan!

Occasional maintenance

Replacing the 321 valves and diaphragms

Diaphragms

Dismantle the crankcase (4). Now, the diaphragm (5) can be replaced. Grease the pump if the liquid has leaked to the inside. Make sure that the draining hole is not obstructed. Reassemble the pump again.

Torque settings for the 321 are:

Crankcase: 60 Nm / 44.4 lbft.

Crankshaft: 70 Nm / 51.8 lbft.

6 - Maintenance

Diaphragm screws: 60 Nm / 44.4 lbft.

WARNING! Before assembling the covers, turn the shaft with the hand and make sure that the connecting rods are ascending and descending respectively. If not change the position of the 4 connecting rods. The ﬁ rst connecting rod must be assembled towards the right-hand side.

SV operating unit

The SV operating unit open and close via a pilot line as in picture A, a small piston activated by the solenoid , opens up a small hole, hereinafter the liquid pressure opens op the larger diaphragm B in the valve, and allows the liquid to ﬂ ow to the nozzles.

The pilot line can block due to sedimentation of chemicals.

Unscrew the 4 Allen bolt, lift up the piston as in picture A, rinse out and reassemble.

6 - Maintenance

CB Section valve

The CB operating motor valve, is ﬁ tted with en end stop, a micro switch.

It can be worn out, if that is the case; the electrical supply is not cut by the micro switch. Therefore the motor keep turning unlimited.

It will burn the fuse.

Pull out the clip as illustrated, lift gently up the gear motor; replace the micro switch as illustrated in the picture showing the gear motor end

Sealing in the operating unit.

Wear and tear parts in the on/oﬀ function of the valve, need to be replaced if the nozzle keeps on spraying weakly after closing a section or the main valve.

Apply thread sealant on the seat and screw it on the end of by-pass hole up to beat. Use the socket wrench. Do not exceed with torque.

Apply the thread sealant on sleeve assembly, and tighten on valve body up to beat using the wrench.

Tighten up to beat the stud B on the seat forcing lightly to obtain a tighten connection.

Assemble all accessories and connect wiring.

ATTENTION! Brown cable to + pole to obtain this position

6 - Maintenance

Cleaning the air kit

ATTENTION! Never access area or adjust deﬂ ector or any other part near the air kit, while tractor is started.

Cleaning of air kit: to prevent unbalance that can cause danger destructive vibrations with dangerous outcome for surroundings.

Inspect for dust and or dirt sedimentation in the air kit.

Hose out the air kit occasionally to prevent dust sedimentation to build up. If it built up, and drop of in uneven locations, it creates unbalance in the air kit, and destroys drive line and the air kit itself.

Rinse the fan blade and inner fan house wall and back end of the air kit. The axial air is designed with natural drain that will let the water out on left and right side.

Do not rinse with high pressure on sealing, as e.g. in the centrifugal clutch area, see separate chapter for clutch maintenance.

The turbine air kit is ﬁ tted with a drain plug that must be removed when rinsing out the dust and other dirt sedimentation from the turbine.

Tank level indicator adjustment

The level indicator reading should be checked regularly. When the tank is empty, the ﬂ oat should lie on the stop pin, of the rod, and the O-ring on the indicator should be positioned at the top position line (A).

If any deviation is found, pull out the plug (B), loosen screws (C), and adjust the length of the cord.

6 - Maintenance

Valves

Remove crankcase cover before replacing the valves. Remember their direction in order to assemble them correctly afterwards!

ATTENTION! When you remove the crankcase covers, you will see that there are 2 valves that are slightly diﬀ erent from the rest. For correct operation, remember to ﬁ t them in the same position and location as before.

Diaphragms

Remove the diaphragm cover. The diaphragm can then be replaced. If the liquid has leaked to the inside of the crankcase, grease the pump thoroughly. Make sure that the drain hole at the bottom of the crankcase is not blocked. Reassemble the pump completely.

The torque wrench settings for the 364 and 464 pumps are the following:

Crankcase cover: 90 Nm

Diaphragm bolt: 90 Nm

ATTENTION! Before tightening the four screws on the crankcase cover, the diaphragms should be centred to ensure correct seating and sealing between the crankcase and the cover. Turn the crankshaft if necessary.

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.

4. If your grease pile weighs for example 10 grams (A), then 1 stroke equals 1 gram of grease.

Once calibrated you can count how many strokes you need to completely lubricate the diﬀ erent grease points on the sprayer according to the speciﬁ cations.

Alternative method

1. Count the strokes, until you have 10 grams of grease piled up on the scale (A).

2. Now you can ﬁ gure out how many strokes to use for applying a certain amount of grease to a lubrication point.

Greasing the Pump

The pump is greased as follows:

1. Factory greased:

300 g grease into each lubrication point (A).

2. Normal operation:

MUST be greased every 50 hours with 30 g grease into each

lubrication point (A).

3. After disassembling the pump (diaphragm renewal, etc.):

MUST be greased with 200 g grease into each lubrication point

(A).

ATTENTION! In order to avoid excessive wear it is important to use a recommended lubricant! See “Recommended lubricants” on page 4.

ATTENTION! The pump MUST be stopped during greasing!
