Overview

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. 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 you are 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 offered 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.

μ

ATTENTION! For models not fitted with brakes the maximum speed is 25 km/h and 40 km/h for those with. This could

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).

HLC circuit

The low pressure circuit is called HLC (Hardi Liquid Circuit). It is alway used in configurations with a diaphragm pump. The
pressure manifold is made of plastic and delivers the flow to three different places. The section on the “HLC Pressure
Manifold” indicates what each of the valves on the manifold are used for.

This manifold is fitted with a safety valve (see section on “Safety Valve”).

The maximum pressure levels for this type of circuit are those allowed for diaphragm pumps.

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 pum p a nd is u se d to s el ect wh er e
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.

μ

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.

μ

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

μ

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’.

3 - Description

13

Blue valve – Blue disc = Return valve

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

agitator and the rinsing nozzle for internal cleaning (optional), as well as
the Turbofiller (optional) or powder mixer. Do only open the manifold
valve in order to sent pressure the desired device, as example given the
Turbofiller.

Pressure manifold

It is made of plastic 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).

Suction and pressure pulsation dampers

The 3 21 pum p is fitted wit h a pulsatio n damp er on suc tion a nd press ure
sides. The pressure side damper is pressureized. The dampers will
reduce pulsations and secure an even flow from the pump.

Agitator

At the front and on each side of the inside of the tank there are two
ventury-shaped agitators. The agitators activated by a valve on the
pressure manifold.

Each agitator has a Ø 3mm nozzle (D).

Operating unit

The mistblower can be equipped with following types of operating units: MC/2, SV/2 and EVC/2 (low pressure).

MC/2 Operating unit

It has two section valves which control RH and LH sides. The section valves are remote controlled from the tractor cab by via
two bowden cables.

EVC/2 Operating unit

An electric operating unit with a control box fitted inside the tractor cab. It allows operation of all the spraying functions
from the tractor. There is no pressure hose near the user, to avoid the risk of contamination of the operator. This operating
unit is fitted with pressure compensation valves on the section valves.

Filters

The pressure filters are located on the bumper next to the air outlet
nozzle. In the HLC circuit the filters are made of plastic and in the HPC
circuit they are made of brass.

All filters should be kept in good condition and cleaned regularly. Make
sure you to use correct combinations of filter and mesh size. The mesh
size should always be less than the average of the total flow from the
nozzles.

Powder mixer

This is used to rinse the filter basket intank’s filling hole when adding
powdered products that do not dissolve properly form lumps on
contact with the water in the tank.

After using the powder mixer it must be disengaged as it uses a large
amount of the available pump capacity.

Chemical inductor, TurboFiller (optional)

The TurboFiller allows filling of both powder and liquid spray chemicals
safe and conveniently when standing next to the machine.

The Turbofiller is neatly stowed away to the bay under the main tank
when not in use.

μ

ATTENTION! Local legislation may require chemicals to be filled
by use of a chemical inductor - Always follow local legislation in
force at any time.

TurboFiller suction valve

The valve is used simultaneously with the TurboFiller. The valve has 2
settings: Continuously open or spring loaded normally closed. Open the
valve when chemicals are to be filled into the TurboFiller.

TurboDeflector valve

This TurboDeflector valve activates the Vortex flushing of the TurboFiller.
Lift the lever to lock it in open position for continuous liquid rotation in
the hopper.

Chemical Container Rinsing lever

The upper lever is used for two purposes:

When the TurboFiller lid is open: For rinsing empty containers. Place the
container over the rotating flushing nozzle in the middle of the
TurboFiller to rinse the inside of the container.

When the TurboFiller lid is closed: Use the Chemical Container Rinsing
lever to rinse the hopper when the filling of chemicals is completed.

€

DANGER! Do not press the lever unless the multi-hole nozzle is covered by a container as spray liquid may otherwise
hit the operator.

Axial blower units

Technical information

The air kits fitted 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 offers 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 AG920 air kits

The AG820 and AG920 air kits are fitted with a grid with 9 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 920 mm 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.

€

NEVER exceed 540 r.p.m. on the tractor P.T.O.! The fan may explode if overspeeded!

€

KEEP AWAY from the air inlets and outlets while the fan is on. Some objects may be shot out of the air outlet or a
piece of clothing could be sucked into the air inlet.

±

The fan is the most dangerous part of the machine. Do not try to replace any of the parts without consulting your
HARDI dealer first. Any service job or modifications on fan and air kit is to be carried out by your HARDI dealers
qualified technicians.

Centrifugal Blower Units

General information

The blower unit is located at the back of the machine. It contains a gearbox unit, blanking plate, casing, outlet hoses and
nozzles, turbine and clutch.

There are two different turbine models: the steel model assembled in P540 and P540D centrifugal blower units, and the
aluminium model assembled in HF600 blower units.

μ

ATTENTION! The clutch is one of the most important parts in the blower unit in terms of safety. Make sure that it is in
perfect conditions (i.e. that it is not blocked, etc.). Otherwise, it could cause the blower unit to explode.

HF540 and HF540D blower units

The air kit should adapt to the requirements of the crop in order to give the best application results. The following section
gives more details about the different pneumatic air kits available.

The letters HF***D means High Flow and Double, respectively. They have a polyesther casing and turbines with 600 mm of
width.

Pneumatic spray system

The pneumatic system is low pressure. This system takes advantage of
the high air speed in the spout outlet to break the spray liquid and give
a very fine mist together with turbulence. Using the deflectors at the
spout outlet, the mist means that the liquid is 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 Paraflow 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 fine mist together with turbulence. Using the deflectors at the tube outlet, the mist means
that the liquid is distributed uniformly.

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

Paraflow tube with 4 in-line atomizers

Paraflow tube with 6 in-line atomizers

μ

ATTENTION! Ceramic nozzles are used for the standard
pneumatic system and the paraflow system. This type of nozzle
has two positions. If the nozzle is fitted so that the flow enters on
the flat side, less flow 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 liq uid wi th an eve n distribution . The air reaches h igh 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.

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 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.

μ

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.

Booms

General information

The pneumatic and hydropneumatic booms, B11, B20, B30, B40, B50 and B51 can be easily regulated and adapted to the
vegetation, ensuring correct treatment.

Regulation is generally mechanical. Some booms, and according to the equipment, also include hydraulic cylinders that
allow you to vary the boom or boom arm height individually, for example in the B40 boom.

Regulating the booms

The B20 and B30 booms allow you to regulate treatment height. By
loosening the two screws (A), the boom can be opened to adapt it to
the vegetation.

With the cylinder B (according to model), the height of the boom can be
changed. This movement allows the boom to be adapted to different
heights and faciliates turning in difficult locations.

The screws C also allow you to vary the height of treatment, using the
vertical boom member that holds the vertical delivery tubes instead of
changing the boom width (point A).

The B40 boom can also be regulated mechanically with the two screws
D on the vertical member of the boom. The width of treatment can be
varied by loosening these two screws slightly.

Another way of adjusting the treatment width is with the screws E, so
that the position of the vertical member can be changed.

Cylinder F allows you to individually raise the height of one of the arms
of the boom to adapt it to the terrain and crop conditions.

This adjustment is recommended for working on slopes.

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 fitted 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 fit a blind cap.

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 fitted 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 wanes
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 flow effect 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.

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).

Adjusting the fan

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.

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.

μ

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!

TurboFiller rinsing

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

When TurboFiller lid is open

For cleaning empty containers. Put container over the rotating flushing
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 flushing 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 filling of chemicals has ended. Press the Chemical
Container Cleaning lever and the TurboFiller suction valve at the same time to activate the flushing nozzle in the middle of
the TurboFiller and empty out the TurboFiller rinsing liquid. Do this 3 times and after the last flushing 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.

μ

ATTENTION! The TurboFiller needs to be cleaned thoroughly after finishing spraying again to be sure it is clean before
spraying other crops that may be sensitive to the chemicals just used. See section Cleaning on page 55 for details.

Adjusting the EVC/2 operating unit

The EVC operating unit must be adjusted with clean water before
spraying with chemical products.

Adjusting the pressure:

1. Select the correct nozzle by turning the nozzle holder if the
equipment contains a double jet. See the ‘Spraying techniques’
booklet.

2. The ON/OFF switch (A) is in the down position.

3. The two section valves (B) are in the down position.

4. The pressure switch (C) must be activated to set the pressure to

minimum.

5. Put the tractor in neutral and adjust the PTO to the same
revolutions as during spraying.

6. Adjust the pressure by toggling the switch until the pressure
gauge indicate the desired pressure.

To adjust the constant pressure valves, proceed as follows:

1. Open both section valves on the control box.

2. Increase the pressure (e.g. to 10 bar).

3. Close one of the section valves.

4. Adjust the constant pressure valve (D) of the closed section valve

until the pressure gauge shows 10 bar again.

5. Open the section valve again and repeat the procedure with the
other section valve.

6. Test by opening any of the section valves individually. If the operating unit is correctly adjusted, the pressure should
remain stable.

Adjusting the BK/2 Operating Unit

A manual low-pressure operating unit that can be fitted in
configurations with diaphragm pumps.

By flipping two lever taps, the right- and left-hand sections of the spray
line is opened and closed.

Using a mechanical remote ON/OFF control, will control the the will
open or close the main valve.

Before starting to spray the pressure must be adjusted. Adjust the
pressure by turning the red handle in the centre of the operating unit
next to the pressure gauge. Turn clockwise to increase pressure or anti­clockwise to decrease it. Check the pressure gauge to see when the
correct pressure is reached.

μ

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

During this procedure, the individua l return capacity of each section is adjusted, so t hat 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.

μ

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

μ

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

μ

ATTENTION! ONCE THE PRESSURE ADJUSTMENT HAS BEEN PERFORMED, IT ONLY NEEDS READJUSTMENT WHEN:

1. ANOTHER NOZZLE WITH A DIFFERENT 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 configurations 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 controled 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.

μ

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.

μ

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

47

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.

μ

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.

μ

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

μ

ATTENTION! If the sprayer is cleaned with a high pressure 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 different purposes.

μ

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

48

• When empty, close the TurboFiller suction valve again.

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.

μ

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.

μ

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.

μ

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

Transmission shaft

The universal joints and bearings should be lubricated with grease. At
points marked (A), this should be done after every 10 working 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 located at the crankshaft axle. The grease travel 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.

μ

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

Filters and fittings

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

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

μ

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

μ

ATTENTION ! Each time you remove a fitting 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 fitting in
its housing

μ

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

6 - Maintenance

51

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.

μ

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.

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.

Operational problems

General information

In almost all breakdowns, the same factors always seem to be present:

1. Small cracks or air leaks in suction side reduce the pump’s capacity or stop suction completely.

2. A blocked suction filter causes the pump not to suck properly.

3. Clogged pressure filters cause pressure to rise on the pressure gauge but to fall at the nozzles.

4. Foreign bodies in the valves can cause the valve to not close completely. This reduces the pump’s performance.

5. Poorly re-assembled pumps, especially diaphragm housings, causes the pump to suck air and hence, reduces or

decreases the pump suction.

6. Hydraulic components that are contaminated with dirt result in rapid wear to the hydraulic system.

Therefore ALWAYS check that:

1. Suction, pressure and nozzle filters are clean.

2. Hoses have no leaks or cracks, especially the suction hoses.

3. Gaskets and o-rings are in good condition.

4. Pressure gauge marks the correct indication. Correct dosage depends on its accuracy.

5. Operating unit is in good working order. Use clean water to check it.

6. Hydraulic components are maintained clean.

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 suction fitting and 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

being used, check that agitation is on.

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

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.

Blower unit

FAULT PROBABLE CAUSE POSSIBLE SOLUTION

Excessive noise or vibrations in the blower
unit

The fan is incorrectly counterbalanced Balance the fan again

The nuts that hold the air kit are loose. Tighten the nuts.

The clutch pads are broken or worn. Change the pads and the clutch springs or replace the clutch for a

new one
