Safety Information For Operators

General Safety and Accident Prevention

Before use or starting up the sprayer and the tractor, always check the

• roadworthiness

• operational safety

Risk of crushing, cutting, catching, squeezing, getting trapped, being drawn in or being struck by sprayer parts due to inadequate roadworthiness and operational safety.

Beside these instructions, comply with the generally applicable national safety and accident prevention regulations.

The warning symbols and other labels attached to the sprayer provide important information on safe sprayer operation. Compliance with this information is in the interests of your safety.

Keep the spray boom in folded position, whenever the sprayer is not coupled to a tractor. Unfolding the boom on an uncoupled sprayer will shift the balance point of the sprayer causing a risk of overturning.

Before driving off and starting up the sprayer, check the immediate area of the sprayer - look out especially for children and instruct them and other unauthorized persons to stay out of reach of the sprayer. Ensure that you can see clearly.

Drive in such a way that you always have full control over the tractor with the attached sprayer. In d oing so, take your personal abilities into account, as well as the road, traffic, visibility, weather conditions and the driving characteristics of the tractor and of the connected sprayer.

Slow down when driving in uneven terrain or when making sharp turns, as the sprayer might be in risk of turning over.

It is forbidden to ride on the sprayer or use it as a means of transport.

It is forbidden to stay in the working area of the sprayer’s drawbar, on the sprayer’s platform or behind the operating area (the tractor), unless the hydraulic pressure to the sprayer has been switched off.

Only authorized persons are allowed inside or outside the tractor cabin during operation.

Keep persons, children and animals away from the operation areas of the sprayer and from the sprayer’s equipment. Be careful when manoeuvring the sprayer, especially when reversing, as there is a risk of hitting people or surroundings.

Avoid eating, drinking or smoking while spraying or working with equipment contaminated with chemicals.

The chemicals used for spraying are dangerous to your health! In case of ingestion, poisoning or damages to your skin or face, immediately seek medical advice. Remember to identify the chemicals used.

Coupling and Uncoupling the Sprayer

Only connect and transport the sprayer with tractors suitable for the task. See the section “Technical Specifications” in this book to make sure that the tractor matches the requirements to operate the sprayer.

When coupling sprayers to the tractor's three-point linkage, the linkages of the tractor and the sprayer must always be the same.

Connect the sprayer to the prescribed equipment in accordance with the specifications.

When coupling sprayers to the front or the rear of the tractor, the following may not be exceeded:

• the approved total tractor weight

2 - General Safety Instructions

Field Sprayer Operation

Observe the recommendations from the manufacturer of the crop protection product in respect of

• personal protective equipment

• warning information on exposure to crop protection products

• regulations on dosing, applications and cleaning.

When there will be exposure to the crop protection product, wear the proper personal protective equipment. This may differ depending on the chemical being sprayed. Follow the local law. Wash and change clothes after spraying. Wash tools if they have been contaminated.

Observe the information in the national plant protection law.

Keep hoses, pipes or other lines closed, when they are under pressure.

Only use genuine HARDI hoses and hose clamps for replacement, which stand up to chemical, mechanical and thermal requirements.

The rated volume of the spray liquid tank must not be exceeded during filling. If overfilling, some sprayer functions may be disabled. However, the main tank is a little oversized to allow for foaming.

When using tractors with a cab with ventilation fans, replace the fresh air filters with activated carbon filters.

Observe the information on the compatibility of crop protections and substances for the field sprayer.

Be aware that some crop protection products have a tendency to stick together or settle when being mixed.

Do not fill the sprayer with water from bodies of water, which are open to the public. This is for the protection of people, animals and the environment due to the risk of contamination.

Only fill the sprayer using a free flow of water from the mains water supply or from an external water tank.

Environmental Precautions

It is essential to reduce the environmental impact of plant protection chemicals to a minimum. Particularly the soil, subsoil water, streams, lakes, flora and fauna must be in focus. Contamination of subsoil water must be prevented by paying particular attention to avoidance of spot contamination of the soil in connection with filling and washing and parking of the sprayer.

If any concentrated chemicals are spilled on the soil, the contaminated soil should be removed and sent for cleaning at a capable facility. Follow local regulations regarding disposal. This must be done to avoid seepage of chemicals to the subsoil waters. Avoid spillage - use the chemical filling device for filling the sprayer with chemicals.

Do not overfill the main tank. The rated volume inside the main tank is stated with large printed numbers on the outside of the tank. If overfilling, the spray liquid could leak from the sprayer causing contamination of the soil.

Before filling the sprayer with plant protection chemicals, the sprayer must be calibrated to apply the precise dose rate selected. The important input sensors are the flowmeter and the speed sensor.

It is recommended to establish a proper filling and washing location with hard, impenetrable surface drained to a receptacle if the sprayer is always filled or cleaned on the same spot at the farm. If a washing/filling location is NOT available, the following precautions should be taken:

• The sprayer should only be filled with clean water at the farm

• The plant protection chemicals must be added and mixed in the field to be sprayed

• Select a different location each time the sprayer is refilled.

2 - General Safety Instructions

Service Work Precautions

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 different options on the sprayer – to the operating unit, to the bottle cleaner, to the Powder mixer in strainer etc., all according to configuration of options. The suction manifold in same area allows suction from main tank, rinsing tank (only on Zaturn) or external water source, if fitted, depending on its configuration.

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

Diaphragm pump

Pumps with a diaphragm: Models 364/7 or 464/10

They are low pressure and robustly built. Use only grease for lubrication. 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 (Rinse tank only available on Zaturn) 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 identified by coloured discs fitted on the valves themselves. The symbols correspond to the optional accessories, and are located on the discs for quick identification 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 fluid)– the valve needs to be serviced.

For more information, see the section on ‘Maintenance’.

Axial blower units

Technical information

The air kit fitted on the HARDI ZATURN mist blowers are the AG820. The air kit fitted on the HARDI MERCURY can be either a SF65 or SF85. The kits have a polyethylene housing and fan blades made of a hardened synthetic material. Their aerodynamic shape offer 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.

AG820 and SF65

The air kits are fitted with a grid with air guides at the air intake, which forms the air flow before reaching the fan, to decrease the imbalance in the airflow. The fan is either 820 or 920mm of diameter and is fitted 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.

There needs to be a CV joint on the side of the tractor. The length of the drawbar can be adjusted (see section “Adjusting the length of the drawbar”).

Turnable drawbar

This is attached to the tractor’s lift arms. Before engaging the tractor PTO make sure the diameter of the shaft fits the ball couplers at the lift arms. Also make sure to fit the securing pins and check that the tractor’s wheels do not touch the mistblower when turning.

Th is type o f coupl ing al lows n arrow turns, if a CV j oint is fitted at th e mist blower’s power intake. The length of the drawbar can be adjusted (see section “Adjusting the length of the drawbar”).

3 - Description

The turnable drawbars, model X and Y are fitted under the rear axle of the tractor, a common arrangement on smaller fruit orchard models of tractors. Important that the two stop bolt are tighten up, to avoid slack

Danger! Angle transmission shaft fitted. Tight turns with PTO engaged may damage the transmission shaft, the pump

€

crank shaft and induce huge vibrations through the gearbox. This may lead to severe damages on gearbox and/or fan.

Wed ges

The wedges are located on the left-hand side of the machine. They should always be carried in their support so they are available when required.

3 - Description

Boom

The boom fitted to the MERCURY COVAMAX has numerous features that enable flexibility for operators when setting up and operating. Some of the benefits are;

• Lift

• Fold

• Tilt

• Breakaway Arms

• Adjustable nozzle positioning and directing

• Low maintenance

Breakaway Arms

To minimise damage to equipment or crops should the boom collide with an object, a breakaway feature is incorporated into the boom. A pivoting hinge mounted on a rear spar of the boom centre allows the boom tubes to independently move out should the boom arm come in contact with an object.

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 five 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.

General information

Unloading the mistblower from the truck

When unloading the mistblower from a van or truck with the aid of a hoist or crane, use the lifting points shown in the illustration, and make sure that the straps or cords used for the purpose are strong enough.

DANGER! Do not stand underneath or beside the machine

€

when it is being loaded or unloaded.

4 - Sprayer setup

Before starting up for the first time

Although the metal parts of the mistblower have received a strong protective surface treatment, a film of anti-corrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) should be applied to all metal parts to prevent the enamel from being discoloured by the chemical products; it will also make it easier to clean the mistblower.

ATTENTION! This treatment should be repeated whenever the protective film wears off.

Counterweights

Check whether a counterweight is required on the front of the tractor when coupled to the machinery to prevent excessive rocking or an accident from occurring.

4 - Sprayer setup

Mechanical connections

Adjusting the drawbar length

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

2. Loosen the three bolts (A), located in the area where the drawbar

is connected in 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 uncoupled from the tractor; when it is coupled, it will be fastened to the left side of the mistblower chassis using two pins.

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

Connecting the ring drawbar

This is attached to the standard clevis-type coupler closeto 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 in another section

Connecting the articulated drawbar

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 in another section.

Lock device on turnable drawbar

The turnable drawbars are fitted with a lock device, once down in forward and horizontal position; the pivoting effect 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.

Adjusting the track width (only available on some model)

To adapt the track width to the terrain, a simple adjustment of the semiaxles needs to be performed.

Proceed as follows to correctly adjust the width:

4 - Sprayer setup

1. Raise the machine at the back so the wheels do not touch the ground.

2. Loosen the two nuts and bolts (B) that fasten the axle inside the housing.

3. Push the axle inwards or outwards, depending on whether greater or less track width is required.

4. When the axle is in the correct position, tighten the bolts (A) and the locknuts (B) again.

5. Repeat this operation with the other axle.

DANGER! Do not remove the axle from the housing more than that allowed. The correct position for the axle is when

€

the axle is properly fastened with the two bolts (b) in the housing.

Adjusting the axle position (Wheel base)

Depending the air kit fitted to the equipment and the adjustment made to the chosen drawbar, the position of the axle may need to be adjusted to improve the machine’s stability.

DANGER! Risk of personal injury. Before working underneath the

€

machine make sure it is lifted and supported properly! Never rely on a hydraulic jack only.

Proceed as follows to correctly adjust the width:

1. Raise the machine at the back so the wheels do not touch the ground.

2. Remove the semi-axles.

3. Loosen and remove the two bolts (A) that fasten the axle housing

on both sides of the frame.

4. The housing needs to fitted further back if the machine jumps at the front when empty.

5. Tighten the bolts (A) again when the housing is in the desired position.

6. Re-fit the semi-axles.

ATTENTION! Always retighten all bolts again after a few hours work.

4 - Sprayer setup

Connecting the transmission shaft

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 first 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 profiles afterwards to remove burrs.

5. Grease the profiles and reassemble male fitting and female fitting.

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

7. Place the input part towards the tractor. Fit the chains to prevent

the protection guards from rotating with the shaft.

ATTENTION! To ensure long life of the driveshaft and prevent

possible damage to the equipment, try to avoid working at angles of more than 15°.

4 - Sprayer setup

Hydraulic connections

General information

Make sure that the couplings are clean before fitting them!

After pressing the brake pedal and when the system is filled with oil, check the level of hydraulic oil in the tractor and refill if required.

DANGER! Testing the hydraulic system should be done with care. Air may have entered the system and cause sudden

€

movements.

DANGER! Oil leakage: Do not use your hands under any circumstances to locate a leakage in any point in the hydraulic

€

system. Due to the system’s high pressure, the oil could penetrate the skin.

Electrical connections

General information

If your equipment includes an electrical component, please note the following information to correctly connect the equipment and to prevent problems when working.

The voltage required by the electrical components is 12 V. Before connecting any component, make sure that the polarity is correct.

Red wire = 12 V (+ positive)

Black wire = (- negative)

This is the standards for the majority of modern tractors. If your tractor has another type of power supply connector, the supplied connector will need to be removed and adapted to the tractor connector.

Operating unit

Find a place in the tractor’s cab where it is possible to fit the control box so you can operate it as comfortable as possible. The most recommended place is to the right of the driver’s seat.

The control box must be properly attached to prevent it from being hit or from excessive vibrations.

The connector type is universal and it should be able to be connected to any tractor. Do not connect into coincidently wires in tractor cabin, as it will not secure stable power and current.

Minimum requirement: min 11V max 13 V Amp. Per SV section 2.5

Amp. Per CB section 0.75

As an emergency solution, remove the connector and splice the wires directly to the battery, remember to have fuse in between.

ATTENTION! The control box must be properly attached to

prevent it from being hit or excessive vibrations.

The connector type is universal and it should be able to be connected to any tractor.

Boom Adjustments

Boom Width - Row Spacing

The position of the out reaching arms can be regulated to alter the width of the boom, in order to adapt the machine to match the row spacing. Adjustment is achieved by loosening clamps on the horizontal bar and extending or shortening the telescopic tubes to the desired width. Once the required position has been chosen retighten clamps to prevent any movement of the bar.

Note: Both the inner and outer boom sections may be

repositioned to suit user requirements.

Crop Height Adjust

As with the adjustment it is also possible to adjust the crop height. Vertical delivery tubes are clamped to the vertical boom member. By loosening the clamps the whole tube assembly can be repositioned higher or lower to suit current crop heights.

Note: Both the inner and outer boom sections tube lengths

may be altered to suit user requirements.

4 - Sprayer setup

Adjustable Boom Tube Length & nozzle positioning

The boom tubes and nozzles for the MERCURY COVAMAX include features that enable the operator to set the machine to suit their particular spray application needs. These features are;

• Boom Tube length adjustment

• Positional Nozzles

Boom Tube Adjustment

The boom tubes are able to be trimmed to length to suit your spraying needs. By removing the band clamp fitted to the lower section of the boom tubes and then removing the lower section, the upper section may be cut to the desired length then reassembled with the lower section.

Located inside the boom tubes and nozzle shrouds are fluid supply lines and nozzle body assemblies. Care should be taken not to damage any of these items when making adjustments to the boom tubes.

Nozzle Positioning

The ball and socket joint design of the nozzles allows for independent positioning of the nozzles to aid even dispersion of spray to gain better results in your spray application.

Fluid Hoses

The high pressure tubes inside the booms that feed fluid to the nozzle bodies are all connected through the use of ‘push-in’ quick release fittings similar to the picture shown. To disconnect a tube from the fitting, push the plastic ring in towards the body of the fitting and pull the tube out of the fitting. If the tube will not release try slightly pushing the tube into the fitting then back out again while making sure the plastic ring is pushed in.

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 fits most tractors. Threaded mounting holes may be hidden behind 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 staggered so that, if correctly orientated, all boxes will line up.

ATTENTION! See also the controllers instruction book for further

details of fitting the controller equipment.

Road safety kit

Connect the plug for rear lights to the tractor’s 7-pin socket, and check the function of rear lights, stop lights, side lights and direction indicators on both sides before driving.

The wiring is in accordance with ISO 1724. See section in “Technical specifications”.

100 -120mm

ATTENTION! Turn OFF all work lights when driving on public roads!

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 sufficient power supply. The delivered power connectors follows the standard of most newer tractors. If you have a tractor with another power connector, it is necessary to disassemble the connector and fit it to the actual tractor connector.

The number and the type of connectors may vary on the specific sprayer, depending on its equipment.

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 persons and animals or damage to crops

In the event that the machine needs to be in operation (agitation) while driving along public roads until reaching the field, 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

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.

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).

5 - Operation

While moving the Sprayer

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

The boom must unfold, and stay firmly, stiff, not wobbly . If the boom is not held firmly unfolded during spraying, it will auto destroy structure due to movements, caused from lack of firm 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 firm while working. To reinforce, eventually a trapeze or pendulum suspension can be activated, but it can’t be rigid, it must be movable and floating.

5 - Operation

Adjusting the fan A6820 and SF65/SF85

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 flow and power consumption. Increasing the angle (maximum angle, pos. 4 (45º)), will increase the air flow and power consumption. It allows the mist blower to be adapted to the different 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.

ATTENTION! The fan must be calibrated correctly after changing the pitch setting. For technical details ask your dealer

and factory.

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 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 mistblower 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, 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 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 filled 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.

DANGER! Do not place the filling hose inside the tank. Keep it out

€

of the tank at all times and only point it towards the filling hole. If the pressure hose were 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-filling. Follow local

legislation in force at any time.

5 - Operation

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 specified, 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 fluid 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 fluid remaining.

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.

Cleaning and maintaining the filters

Clean filters ensure:

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

• Nozzles are not blocked during spraying.

• The pump has a long service life. A clogged suction filter will result in pump cavitation. The main filter that protects the

mistblower parts is the suction filter. Check it regularly.

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 filters and clean. Be careful not to damage the mesh. Replace suction filter top. Replace filters

when the sprayer is completely clean.

5. With the pump running, rinse the inside of the tank. 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 field again or on the soakaway.

6. After spraying the liquid out, stop the pump and fill at least 1/5 of the tank with clean water. Note that some chemicals require the tank to be completely filled. 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 filters, remove and clean them

immediately.

10. Replace all the filters 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 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.

Use of rinsing tank and rinsing nozzles (Zaturn)

The incorporated rinsing tank can be used for two different purposes.

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

In-field diluting before cleaning

In-field 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.

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:

• Turn the pressure valve towards TurboFiller (if fitted) and open the TurboFiller suction valve.

• Open TurboDeflector valve and close it again when clean water comes out of nozzles.

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

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

5 - Operation

• When empty, close the TurboFiller suction valve again.

• Turn the suction valve towards “Main tank” and the pressure valve towards “Spraying” and spray the liquid in the field

just sprayed.

Cleaning of Main tank:

5. Turn the suction valve towards “Rinsing tank” and the pressure valve towards “Internal Tank Rinsing”. Remove the filling 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.

12. Clean the whole system again.

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

14. Rinse the sprayer with clean water afterwards.

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 field until all nozzle tubes/nozzles have been

flushed with clean water.

4. Disengage 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 the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended.

6 - Maintenance

Lubrication

General Info

Always store lubricants clean, dry and cool - preferably at a constant temperature - to avoid contamination from dirt and condensed water. Keep oil filling jugs, hoppers and grease guns clean, and clean the lubricating points thoroughly before lubricating. Avoid skin contact with oil products for longer periods.

Always follow the quality and quantity recommendations. If no quantity is recommended, grease the nipple until new grease becomes visible.

6 - Maintenance

Boom lubrication

The boom contains several points requiring lubrication as listed below. It is recommended to lubricate these points regularly to maintain boom efficiency.

Fold Cylinder Pivots

Tilt Cylinder Pivots

Tank transmission shaft

Loosen the two nuts on the PTO protection in ends, pumps and gear

box.

Twist and pull back the protection.

Grease the yoke .

Put back both protections and tighten the nuts.

Driveshaft

The universal joints and bearings should be lubricated with grease. At points marked (A), this should be done after every 10 work ing hours, and the tubes and axles (B) every 50 hours.

Remember to lubricate the joints of the transmission shaft between pump and fan gearbox as well.

Diaphragm pump

Grease the pump every 50 working hours or once a month, through the grease nipple situated on the crankshaft axle. The grease goes along the grooves in the crankshaft to reach the crankcase where it is distributed around bearings, conrods, etc.

Greasing is carried out in the same way on both pump models 363 and

463.

Pump model 364 and 464 have external central grease nipples

ATTENTION! Insufficient greasing of the pump could cause it

to overheat and break the moving parts inside.

6 - Maintenance

Filters and fittings

Revise the filters every 50 working hours. Apart from ensuring that they are clean, make sure that the mesh is in good condition. Otherwise, the effectness of the filter will be nil.

Whenever dismantling any filter or hose pipe, take care not to pinch the o-rings fitted to them. When replacing the pipe fitting, smear the o-ring with oil or grease so that it falls easily into place in its groove.

ATTENTION! If the filter is not in good condition, it could cause numerous undesired stoppages during the working

day, extending the working time required.

ATTENTION! Each time you remove a fitting to check the condition of its o-ring or for any other reason, remember to

lubricate the seal with oil or grease to prevent it from being pinched or breaking when reassembling the fitting in its housing

ATTENTION! Insufficient greasing of the pump could cause it to overheat and break the mobile parts inside.

6 - Maintenance

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.

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 beyound 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.

6 - Maintenance

6 - Maintenance

Storing the mistblower at the end of the season

When the spraying season is over, you should devote some extra time on the machine before storing it. If any chemical residues are left on the mistblower for a long period, it can reduce the service life of the components. To keep the mistblower intact and protect the components, you should perform the tasks as part of an off-season storage programme.

1. Clean the mistblower completely inside and out, as described in ‘Cleaning the mistblower’. Make sure that all the valves, hoses and auxiliary equipment have been washed with detergent and rinsed with clean water afterwards, to ensure that no traces of chemical products are left on the mistblower.

2. Replace the o-rings and repair any possible leaks.

3. Empty the mistblower completely and let the pump work for five minutes. Open all the valves to drain as much water

as possible from the circuit.

4. Pour approximately 50 litres of anti-freeze mixture in the tank (1/3 anti-freeze and 2/3 water).

5. Start the pump and operate the controls of the 3-way valves, operating unit, etc. so that the anti-freeze is distributed

throughout the entire circuit. Open the main ON/OFF valve and the distribution valves so that the anti-freeze is delivered through the nozzles also. The anti-freeze prevents the o-rings, seals, diaphragms, etc. from drying out.

6. Lubricate all the lubrication points according to the lubrication scheme. Disregard the normal lubrication intervals in this case.

7. When the mistblower is dry, remove the rust from any possible scratches or marks in the paint, and touch up the paintwork.

8. Remove the pressure gauge and store it a vertical position in a frost-free location.

9. Apply a thin layer of anti-corrosion oil (e.g. SHELL ENSIS FLUID, CASTROL RUSTILLO or similar) to all metal parts. Do not

apply to hoses or rubber parts.

10. All the electric plugs and sockets must be kept in plastic bags to protect them from damp, dirt and rust.

11. Remove the control box from the tractor (if fitted), and store it in a clean, dry place (in-house).

12. To protect the mistblower against dust, it can be covered with a tarpaulin. Make sure that it is ventilated to prevent

condensation.

Preparing the machine for use after storage

After storage, the machine should be prepared for safely starting work at the beginning of the season. To start up the machine correctly, proceed as follows:

1. Remove the tarpaulin protecting the machine if there is one.

2. Fit the pressure gauge again. Replace the old Telfon tape.

3. Connect the equipment to the tractor, including electric wires and hydraulic cables.

4. Check the brake.

5. Empty the tank of any remaining anti-freeze.

6. Rinse out the entire fluid circuit with clean water.

7. Fill the tank with clean water and check all functions.

8. If the outer section is to high when is folded. Loosen nu E and turn nut F one turn clockwise, loosen nut I and turn J

one turn counter clockwise. Work has to be done evenly on nut F and J otherwise it will change the vertical adjustment.

9. Fold the outer wing again to see how it fits on the inner section brackets. if necessary unfold the wing again and adjust.

10. When the outer section sits perfect on the brackets. The bolt joints nuts needs to be tightened very hard use a spanner

with 1m extension.

Operational problems

General info

Operational incidents are frequently due to the same reasons:

1. A suction leak reduces the pump pressure and may interrupt suction completely, it also causes pulsing in the pressure hoses.

2. A clogged suction filter may damage suction or interrupt and prevent the pump from running normally.

3. A clogged pressure filter increases pressure in the fluid system in front of the pressure filter. This may blow the safety

valve.

4. Clogged In-line or nozzle filters increase pressure in the pressure gauge but decrease pressure at the nozzles.

5. Impurities sucked by the pump may prevent the valves from closing correctly, thus reducing the pump flow.

6. A poor reassembly of the pump elements, especially the diaphragm covers, causes air leaks and reduces the pump

flow.

7. Rusted or dirty hydraulic components cause bad connections.

8. A badly charged or faulty battery causes failures and misbehaviour in the electrical system.

Therefore ALWAYS check

1. Suction and pressure filters, as well as nozzles, are clean.

2. Hoses for leaks and cracks, paying particular attention to suction hoses.

3. Gaskets and O-rings are present and in good condition.

4. Pressure gauge is in good working order. Dosage accuracy depends on it.

5. Operating unit functions properly. Use clean water to check.

6. Hydraulic components are clean.

7. The good condition of the tractor battery and its connectors.

Fluid circuit

FAULT PROBABLE CAUSE POSSIBLE SOLUTION

On activating, the system doesn’t spray Air in the suction line. Check the suction filter o-ring.

Check the suction tube and fittings.

Check the assembly of the pump crankcase covers and diaphragms.

Air in the system. Prime the pump by filling the hose with water

Suction or pressure filters blocked. Clean the filters

Check the s uction fitting an d make sure that it is not too close to the outlet on the tank floor.

Loss of pressure Incorrect assembly The safety valve’s spring is damaged.

The suction fitting is blocked

The suction filter is clogged

Pump valves clogged or worn Check for obstructions and wear

Defective pressure gauge Check for dirt in the intake

Pressure jumps Filters clogged Clean the filters. Clean with clean water. If powdered product is

Worn nozzles Check that the air flow does not exceed 10%.

Tank suction clogged Check the suction tube

Air suction Reduce revolutions in the PTO

Increase in pressure Pressure filters blocked Clean the filters

Foam formed Air in the circuit Check the o-rings, gaskets, hoses and suction fittings

Excessive agitation. Reduce revolutions in the PTO

being used, check that agitation is on.

Check the voltage of the safety valve of the self-cleaning filter

Make sure that there is return to the tank

Use anti-foaming agent

Leak of pump liquid Diaphragms damaged Replace

The operating unit does not work Fuse blown Check the limit switches. Oil with lubricant if the limit switch does

not make proper contact.

Incorrect polarity Control box: Red - pos (+) Black - neg (-).

Solenoid valves: Brown - pos (+). Blue - neg. (-).

The valves do not close correctly. Check for obstructions in the valves

Check the limit switches

No power Incorrect polarity. Brown is pos. (+), Blue is neg. (-)

Check the electric board

Check that the fuse box makes contact with the bracket.
