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
• the approved tractor axle loads
• the approved load capacities of the tractor tyres
• the approved load capacities of the tractor hitch points.
Secure the tractor and the sprayer against rolling unintentionally before coupling or uncoupling the sprayer.
It is forbidden for people to stand between the sprayer to be coupled and the tractor, while the tractor is moving towards
the sprayer.
24
2 - General Safety Instructions
Any helpers may only act as guides standing next to the vehicles, and helpers may only move between the vehicles when
both are at a standstill.
Before connecting the sprayer to or disconnecting the sprayer from the tractor's three-point linkage, secure the operating lever of
the tractor hydraulic system, so that unintentional raising or lowering is prevented.
When coupling and uncoupling sprayers, move the support equipment (if available) to the appropriate position (check
stability and strength of the support).
When actuating the support equipment, there is a risk of injury from crushing and cutting points.
Be particularly careful when coupling the sprayer to the tractor or uncoupling it from the tractor. There are crushing and
cutting points in the area of the coupling point between the tractor and the sprayer.
It is forbidden to stand between the tractor and the sprayer when actuating the three-point linkage.
Coupled supply lines
• must yield to all movements while cornering without tensioning, kinking or rubbing
• must not rub against other parts.
Ropes or cords releasing quick couplings must hang loosely, and they must not release themselves when lowered.
Also ensure that uncoupled sprayers are stable.
Use of The Sprayer
Before starting work, ensure that you understand all the equipment and actuation elements of the sprayer and their
function. There is no time for this when the sprayer is already in operation.
Only wear tight clothes. Loose clothing increases the risk of being caught by the drive shaft / PTO.
Only start-up the sprayer, when all the safety equipment has been attached and in the safety position.
Comply with the maximum load for the connected sprayer and the permissible axle and drawbar loads for the tractor. If
necessary, drive only with a partially filled tank.
It is forbidden to
• stand in or near the working area of the sprayer
• climb the sprayer
• stand or sit on the sprayer
• stand in the turning and swivel range of the sprayer.
There are crushing and cutting points at externally actuated sprayer points, e.g. hydraulic cylinders.
Only actuate externally actuated sprayer parts when you are sure that no one is standing within the prescribed safety
distance.
Before leaving the tractor:
• lower the spray boom to around waist height above the ground or lower, or
• fold the spray boom into the transport position

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.
29

brackets
• if the spray boom is folded up and resting in the transport brackets for service, check visually that the paralift locks are
engaged (the boom is locked in place)
• if the spray boom is unfolded for service, the boom must be lowered, until it reaches its end stop. Place strong trestles
under the boom for support or use a lifting crane for support
• never service or repair any equipment while it is operating
• any service work is preferable carried out on level ground with only authorized persons nearby
• depressurize the hydraulic system for the sprayer to prevent unintentional movements of the sprayer
• switch off the PTO
• switch off the tractor and remove the ignition key to prevent unintentional starting
• activate the parking brake to prevent rolling
• put chocks in front of and behind the wheels to prevent rolling
• electric power must be disconnected from the sprayer
• any service work on electronic /electric parts must be carried out under dry conditions - no rain or splashes from water
or other liquids.
Cleaning
When cleaning nozzles and filters, lower the spray boom to around waist height above the ground. For safety reasons, do
not walk or stand below the boom or paralift during this cleaning work!
Dispose of oils, greases and filters in the appropriate
Cleaning of tanks:
• Due to toxic vapours from spray liquids in the main tank, climbing into this tank is very hazardous. Cleaning should only
be done from the outside.
• Refrain from entering the main tank.

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.

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

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.
μ
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.

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.
50
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
μ
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
μ
possible damage to the equipment, try to avoid working at
angles of more than 15°.

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

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.

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.

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
μ
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!

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
μ
any part of these instructions is unclear, for safety reasons, please contact your HARDI dealer for further information.
ATTENTION!
μ
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.
78
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
μ
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.
μ
ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended.
μ
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.
μ
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.
79
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
μ
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
μ
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
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.
82
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
μ
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
μ
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
μ
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.
μ
83
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
μ
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
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.
