Use of the ZENIT sprayer
The HARDI® ZENIT sprayer is designed for the application of chemical crop protection products and liquid fertilizers. This
equipment may only be used for this purpose. Using the sprayer for any other purpose is not allowed.
Even if no local law requires that the operator must be certified to use the spray equipment, it is strongly recommended
to be trained in correct plant protection and in safe handling of plant protection chemicals to avoid unnecessary risk for
persons and the environment when doing the spray job.
Identification plates
The serial number plate is riveted onto the left hand side of the
frame, indicating the make, model and serial number of the sprayer.
Frame
The frame is manufactured with a tubular profile which provides great durability and resistance to breakages and vibrations. To protect it from corrosion, it is sanded down and covered with a layer of special paint that contains a
polyurethane bi-component with anti-corrosion additives and protection against ultraviolet rays.
Tank
The tank is made of medium-density polyethylene with ultraviolet filters, it has smooth, rounded surfaces that facilitate
agitation and cleaning. Range of volumes: 105 gal. (400 Liters) and 155 gal. (600 Liters).

Liquid system
HC/1 or HC/2 Hydraulic control
The HC/1 or HC/2 hydraulic control consists of a MANIFOLD valve (A)
for operating agitation and the powder mixer, a manual pressure
regulator (B) with built-in safety valve, and a manifold pressure
gauge (C). The blower nozzles are operated with hydraulically controlled section valves using the tractor hydraulics. All of these controls are conveniently mounted in the control bracket located on the
front of the sprayer.
Valves and symbols
The MANIFOLD valve is equipped with symbol decals located on the disc for easy identification and operation. A function
is activated by turning the handle towards the desired function symbol.
ATTENTION! Only the function in use should be open - always close valve when function is no longer needed.
ATTENTION! If a MANIFOLD valve is too tight to operate - or too loose (= liquid leakage) - the valve needs to be
serviced. Please see the “Maintenance” section for further information.
BK/2 Manual control
The BK/2 manual control consists of a Master On/Off valve (A), blower nozzle distribution valves (B) with pressure equalization, manual
pressure adjustment valve (C), pressure filter (D), 2-1/2”pressure
gauge (E) and HARDI-MATIC. The HARDI-MATIC is a mechanical rate
controller that ensures a constant volume of spray solution per acre
at varying speeds in the same gear.
Agitation and the powder mixer are operated with the distribution
valves (F) located next to the safety valve (G).
3.3
Page 18
3 - Description
Safety valve (BK units)
The safety valve acts like a fuse when the circuit carries out an operation that causes a sudden increase in pressure.
This valve normally keeps the return to tank in a closed position by
way of a spring and washer. When the amount of pressure in the circuit is above the maximum allowed for the valve, this opens and
allows the flow to return.
The valve opens at 220 psi (15 bar).
Do not remove the safety valve from the liquid circuit as this could put your safety at risk.
Pump
Diaphragm pump with 2 diaphragms, model 321, with easily accessible valves and diaphragms. Standard = 540 r.p.m (6
splines).
Pressure damper
To avoid the vibrations caused by pressure pulses in the liquid circuit, the 321 pumps are fitted with a pressure damper. The air pressure in the damper is preset at the factory. If adjustment is desired,
see “Operation”section for adjustment procedures.

Axial blower unit
Axial fan - Technical information
The axial fans on HARDI® ZENIT sprayers have been designed with composite blades. Their aerodynamic design offers a
higher quantity and better distribution of air, less noise and less power consumption. They include a centrifugal clutch for
smoother starting and stopping.
Flow levels for the AG820 (32”) fan can achieve 23,500 cfm (40,000 m3/h) depending on the adjustments made to it’s
components.
DANGER! The tractor P.T.O. should never exceed 540 r.pm. as there is grave danger of causing the air kit to explode.
DANGER! Keep away from the air inlets and outlets while the fan is on. Some objects may be expelled from the air
outlet or a piece of cloth could be sucked into the air inlet.
The blower unit is the most dangerous part of the machine. Do not try to change any of the parts without consulting
your nearest dealer beforehand. Adjusting blower units in order to change their characteristics should only be done by
qualified people.
Protection guards
On all axial blower unit models, there are protection guards. They are fundamental for avoiding accidents and stopping
foreign objects from getting inside the fan.
DANGER! Use of the air kit without protection guards is not
permitted.
DANGER! Do not take the protection guards off the equipment while it is in use.
DANGER! Do not go near the fan when the equipment is in
use if you are wearing light or loose clothing.
DANGER! Never put foreign objects inside the fan via the
guard, regardless of whether it’s in use or not.
DANGER! If you notice vibrations or hammering, turn the fan
off immediately.
DANGER! Protect your ears from the fan noise by wearing
appropriate hearing protection.

Centrifugal blo wer unit
Centrifugal turbine - Technical information
The centrifugal turbines on HARDI® ZENIT sprayers have been designed with galvanized steel. Their aerodynamic design
offers a higher quantity and better distribution of air, less noise and less power consumption. They include a centrifugal
clutch for smoother starting and stopping.
Flow levels for the P540 (22”) fan can achieve 6,500 cfm (11,000 m3/h).
DANGER! The tractor P.T.O. should never exceed 540 r.pm. as there is grave danger of causing the air kit to explode.
DANGER! Keep away from the air inlets and outlets while the fan is on. Some objects may be expelled from the air
outlet or a piece of cloth could be sucked into the air inlet.
The blower unit is the most dangerous part of the machine. Do not try to change any of the parts without consulting
your nearest dealer beforehand. Adjusting blower units in order to change their characteristics should only be done by
qualified people.
Protection guards
On all pneumatic blower unit models, there are protection guards. They are fundamental for avoiding accidents and
stopping foreign objects from getting inside the fan.
DANGER! Use of the air kit without protection guards is not
permitted.
DANGER! Do not take the protection guards off the equipment while it is in use.
DANGER! Do not go near the fan when the equipment is in

Gear box
The gear box situated in the air kit is one of the mechanical elements which works the most. The P540 (22”) air kits on the
Zenit sprayer are equipped with two speed gear boxes.
The gear box for the P540 (22”) air kit has two speeds. The speed
ratio is as follows:
P540
1st speed = 1/5.7
2nd speed = 1/6.6
The capacity is 59 oz. (1.75 Liters) of oil for cooling and lubrication.
Use synthetic SAE 30 oil.
See “Maintenance”for how frequently the equipment needs to be
checked.
Pneumatic system
The pneumatic system is low pressure and takes advantage of the high air speed in the spout to break up the spray film
and create a very fine mist that includes some turbulence. The atomizers in the spout spread the mist uniformly in the
shape of a fan.
There are four types of spouts which make up the boom configuration you may have on your sprayer.
A - Cannon with one outlet.
B - Spout with 2 outlets.
C - Spout with 3 outlets.
D - Spout with 4 outlets.
ATTENTION! For this system, ceramic discs are used to determine the flow rate. This type of disc has two possible positions. If the disc is placed so that the flow goes in through the
cone-shaped side, the nozzle will give out more flow than if it
is placed so that flow goes in through the flat side.
3.11
Page 26
3 - Description
Hydro-pneumatic system
The hydro-pneumatic system is medium to high pressure. This system takes advantage of the great amount of turbulence in the cone-shaped, low-volume nozzle and distributes the sprayed mist correctly. The air enters the spout at high
speed and spreads the mist in the shape of a fan.
The ZENIT sprayer uses spouts with three nozzles.

Gener al info
Unloading the sprayer from the truck
When unloading with an overhead lifting device, please observe the
lifting points as shown in the picture, and make sure that the straps
or belts used for lifting are strong enough.
If using a forklift, be careful not to damage the fittings at the bottom
of the tank.
Before putting the sprayer into operation
4 - Sprayer setup
Although the sprayer has been applied with a strong and protective surface treatment on steel parts, bolts etc. in the factory, it is recommended to apply a film of anticorrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) on all metal
parts in order to avoid chemicals and fertilizers discoloring the enamel. If this is done before the sprayer is put into operation for the first time, it will always be easy to clean the sprayer and keep the enamel clean for many years. This treatment
should be carried out every time the protection film is washed off.
Transmission shaft - Operator’s safety
1. Always STOP ENGINE before attaching the transmission shaft to tractor P.T.O. - most tractor P.T.O. shafts can be rotated
by hand to facilitate spline alignment, when engine is stopped.
2. When attaching the shaft, make sure that the snap lock is FULLY ENGAGED - push and pull shaft until it locks.
3. Always keep protection guards and chains intact and make sure that it covers all rotating parts, including CV-joints at
each end of the shaft. Do not use without protection guard.
4. Do not touch or stand on the transmission shaft when it is rotating - safety distance: 5’ (1.5 meter).
5. Prevent protection guards from rotating by attaching the chains allowing sufficient slack for turns.
6. Make sure that protection guards around tractor P.T.O. and implement shaft are intact.
7. Always STOP ENGINE and remove the ignition key before carrying out maintenance or repairs to the transmission shaft
or implement.
DANGER! ROTATING TRANSMISSION SHAFTS WITHOUT PROTECTION GUARDS ARE FATAL.
4.1

Mechanical connections
Transmission shaft - Installation
First installation of the transmission shaft is done in the following
way:
1. Attach sprayer to tractor and set sprayer height in the position
with shortest distance between the tractor and sprayer pump P.T.O.
shafts.
2. Stop engine and remove ignition key.
3. If transmission shaft must be shortened, the shaft is pulled apart.
Fit the two shaft parts at tractor and sprayer pump and measure
how much it is necessary to shorten the shaft. Mark the protection
guards.
WARNING! Make sure the transmission shaft fits properly the
first time it is installed to prevent damage to the sprayer or
tractor.
WARNING! The shaft must always have an overlap (A) of a
minimum of 1/3 the length.
4. The two parts are shortened equally. Use a saw, and file the profiles afterwards to remove burrs.
5. Grease the profiles and assemble male and female parts again.
6. Fit the shaft to tractor P.T.O. and sprayer pump shaft.
ATTENTION! Female part marked with a tractor towards tractor!
7. Fit the chains to prevent the protection guards from rotating with
the shaft.
8. To ensure long life of the transmission shaft, try to avoid working
angles greater than 15°.

Hydrau lic s ystems
General info
Ensure that snap couplers are clean before connection!
After having operated the hydraulics and the system has been filled with oil, check tractor’s hydraulic oil level and top up
if necessary.
DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system
which can cause violent movements of the CANNON spout (optional).
DANGER! Hydraulic leaks: Never use your fingers to locate a leakage in any part of the hydraulic system. Due to
high pressure, hydraulic oil may penetrate the skin.
Hydraulic requirements for HC/1 or HC/2 controls
The tractor hydraulic system requires:
Two single acting hydraulic outlets (one for each hydraulically controlled section valve).
Hydraulic requirements for B20 Hydraulic boom
The tractor hydraulic system requires:
One double acting hydraulic outlet for the lift cylinder.
One double acting hydraulic outlet for individual folding with 4 x 1 multiplier for hydraulic section valves (optional).
The 4 x 1 multiplier kit must be installed before first use (follow the instructions included with the kit). The 4-switch handle needs to be attached to a double acting hydraulic lever on the tractor. The electric switches are used with the
hydraulic lever to control the left and right fold functions of the boom as well as the two hydraulically controlled section

Air systems
Adjusting the fan (axial system only)
The angle of the fan blades can be adjusted to 4 positions. They are
normally factory set to position 3.
Decreasing the angle of the blades (minimum angle, position 1)
lessens the flow and decreases power consumption. By increasing
the angle (maximum angle, position 4) the flow increases, but so
does the power consumption. In this way, the sprayer can adapt
both to the different applications as well as the power of the tractor.
To change the position of the angle of the fan blades, you should
follow these steps:
1.Take off the suction guard.
2. Loosen the Allen screws (A) without taking them out completely.
3. Loosen the Allen screws (B) holding the nut at the back of the fan.
4. With both hands on opposite blades, turn them to the position
wanted between 1 and 4. All the blades should turn at the same
time.
5. Finally, make sure all blades are in the same position (C) before
tightening the Allen screws (A) and (B).

B20 Hydraulic boom operation
The hydraulically activated section valves and boom fold functions
are operated with one hydraulic lever on the tractor using the 4 x 1
multiplier kit. Connect the two hoses from the 4 x 1 multiplier to the
double acting outlet on the tractor that has the electric 4-switch
handle installed to the hydraulic lever (see Sprayer setup section).
The lift function of the boom is operated with a separate hydraulic
lever. Connect the lift cylinder hydraulic hoses to any available double acting outlet on the tractor.
The boom is raised and lowered using the hydraulic lever connected
to the lift cylinder.
The left or right boom is unfolded by pressing the left or right boom
fold switch* on the 4-switch handle and pushing the lever one way.
The boom is folded back in by pressing the same switch and pushing the lever the other way.
The left or right blower nozzles are turned “On” by pressing the left
or right section switch* on the 4-switch handle and pushing the
hydraulic lever one way. The section is turned “Off” by pressing the
same switch* on the 4-switch handle and pushing the lever the
other way. The hydraulic lever can be returned to the neutral position after switching “On” or “Off”.
If you do not like the direction required to activate a function, switch
positions of the hoses in the double-acting outlet for the 4 x 1 multiplier.
* The function of each of the 4 switches on the handle for the
hydraulic lever is determined by how it is originally installed (see
Sprayer setup section).

Liquid an d air s ystem
Filling through tank lid
Water is filled into the tank by removing the tank lid located on top
of the sprayer tank. It is recommended to use water as clean as possible for spraying purposes. Always fill water through the strainer
basket to prevent foreign particles from entering the tank. An overhead tank can be used in order to obtain high filling capacity.
WARNING! Do not let the filling hose enter the tank. Keep it outside the tank, pointing towards the filling hole. If
the hose is lowered into the tank and the water pressure drops at the water supply, chemicals may be siphoned
back and contaminate the water supply lines and source.
To empty the tank, turn the pin on the drain valve located at the
bottom of the tank. To close the drain valve, turn the pin back in the
opposite direction.
Powder mixer
The powder mixer is used to rinse the filter basket when adding
powdered products that do not dissolve properly and would otherwise form lumps on contact with water in the tank.
For operating instructions, see the controls section specific to your
sprayer (e.g. HC/2, BK/2).
ATTENTION! After use, the powder mixer should be turned off
as it uses a large amount of the available flow.
Filling of clean water tank
A clean water tank is integrated into the top of the main tank.
Remove tank lid A, fill with clean water and replace tank lid.
For use of water, turn the ball valve lever B to open tap. The ball
valve is located at the bottom of the clean water tank on sprayer’s
left side. The water from this tank is for hand washing, cleaning of
clogged nozzles, etc. Only fill the clean water tank with clean water.
Capacity: 4 gal. (15 liters).
WARNING! Although the clean water tank is only filled with
clean water, this water must never be used for drinking.

Diaphragm pump
The maximum number of revolutions when in use is 540 rpm. The
diaphragm pump is self-priming and can be run dry without damage.
WARNING! Make sure the pump is properly greased before
operating the sprayer.
ATTENTION! See “Maintenance”section for how frequently the
pump needs to be checked.
Pressure damper adjustment
The air pressure in the damper on the HARDI® diaphragm pump is
factory preset at 30 psi (2 bar). This is suitable for nozzle spray pressures between 45 and 220 psi (3 and 15 bar). If different nozzle pressures are required, set pressure damper at pressures indicated.
5 - Operation
Gear Box
When working with the liquid circuit only, it is not necessary for the
fan to be on. Therefore, it is advisable to put the gear box in the neutral (off ) position.
The gear box is behind the pump. When the gear lever (A) is in the
middle position, the gear box is in neutral.
If you cannot get the gearbox into gear because of interference
between the teeth and sprockets, engage the PTO for a few seconds
and try again.
WARNING! Both the pump and fan should be at a complete
stop before attempting to change gears in the gear box.
5.5
Page 38
5 - Operation
Nozzles
The standard nozzle holders included in axial air kits are made of
brass (A). They can be closed individually by turning them 90°. When
open, they have a range of +/- 15° to vary their inclination. They are
fitted with a non-drip valve (B) to avoid the loss of chemical product
that remains in the lines when the different sections are shut off.
The nozzles (C) are turbulence (also known as ATR) nozzles. They are
color-coded and their pressure ranges from 70 to 215 PSI (5 to 15
bar).
This type of nozzle can also be used with hydro-pneumatic equipment.
ATTENTION! It is not advisable to go over 215 PSI (15 bar) with ATR nozzles as the drops would be far too small and
the product could evaporate in high temperatures or be carried off by the breeze or wind.
The pneumatic system is fitted with ceramic calibrated discs. This
type of disc has two possible positions. If the disc is placed so that
the flow goes in through the cone-shaped side, the nozzle will give
out more flow than if it is placed so that flow goes in through the
flat side.
The function of these nozzles in the pneumatic system is to control
the amount of flow needed to break up the spray film. The pressure
ranges in the pneumatic system range from 0 to 60 PSI (0 to 4 bar).
The CANNON model has a spout made of polyester and is only fitted
on a pneumatic system. It includes 4 bi-jet holders with two nozzles
each. Also included are three adjustable nozzles outside the spout
which allow for proper treating of nearby crops.

Page 39
HC/1 or HC/2 Control
After filling the tank with clean water, locate your sprayer in a suitable location to spray water from the nozzles. Before starting the
pump, make sure the pressure regulator valve (B) is turned all the
way out (counter clockwise).
With the pump operating at 540 r.p.m., slowly turn valve (B) in
(clockwise) until the desired pressure is shown on the pressure
gauge (C).
To activate pressure agitation, turn the manifold valve (A) to the left
towards the agitation symbol.
5 - Operation
To activate the powder mixer, turn the manifold valve (A) to the right
towards the powder mixer symbol.
To turn off both the pressure agitation and the powder mixer, turn
the manifold valve (A) straight up or down.
The left and right blower nozzles are turned on and off by the left
and right hydraulic section valves.
Make sure each hydraulic hose is connected to a separate single-acting hydraulic outlet on the tractor. The nozzles for each section are
turned “On” by pushing the hydraulic lever for that section in one
direction, and turned “Off” by pushing the hydraulic lever for that
section in the opposite direction. The hydraulic lever can be
returned to the neutral position after switching “On” or “Off”.
If you do not like the direction required to activate a nozzle section,
switch positions of the hose in the single-acting outlet for that section.
ATTENTION! The HC/1 control for CANNON models has only one hydraulically controlled section valve.
5.7
Page 40
5 - Operation
BK/2 Manual control
After filling the tank with clean water, locate your sprayer in a suitable location to spray water from the nozzles.
Before starting the pump, turn the main On/Off valve (A) to the “On”
position (“Up”as shown) and turn the HARDI-MATIC valve (C) counter clockwise all the way out.
Open or close levers (F) depending on whether pressure agitation
and/or the powder mixer is required.
Turn the left and right nozzle section valves “On” by pulling the
levers (B) “Down”and towards you (the valves are shown in the “Off”
position).
With the pump operating at 540 r.p.m., slowly turn the HARDI-MATIC
valve (C) in (clockwise) until the desired pressure is reached on
gauge (E). Note this pressure to adjust the pressure equalization
valves below.
ATTENTION! The P.T.O. revolutions must be kept between 300540 r.p.m. for the HARDI-MATIC to function properly.
Adjustment of pressure equalization
Before using the sprayer for the first time, it is necessary to adjust the
constant pressure valves (1). Adjust the valves one section at a time
as follows:
1. Place the first lever (2) in the “Off” position (“Up”).
2. Turn the adjusting screw (1) until the pressure gauge (E) again
shows the same pressure as when both valves were on (Turn the
valve clockwise for higher pressure, counter clockwise for lower
pressure).
3. Turn the lever (2) back to the “On” position (“Down”).
4. Repeat steps 1 through 3 for the other section valve.
When properly adjusted, the pressure should remain the same
whether both valves are open, or if either one of the section valves
is closed.
ATTENTION! Hereafter, adjustment of the constant pressure valves will only be needed if you change to nozzles
with other capacities, but not required if only changing pressure or application rate using the same nozzles.
Operating the control unit while driving
In order to shut off all nozzles, turn the “On/Off” valve (A) to the “Off” position (“Down”). This returns the pump output to
the tank through the return system. The diaphragm non-drip valves ensure instantaneous closing of all nozzles.
In order to shut off one of the nozzle sections, turn the appropriate section valve lever (B) to the “Off” position (“Up”). The
constant pressure device ensures that the pressure does not increase in the section which is still operating.

Cleaning
General info
In order to derive full benefit from the sprayer for many years the following service and maintenance program should be
followed.
ATTENTION! Always read the individual paragraphs. Read instructions for service/maintenance jobs carefully before
starting on the job. If any portion remains unclear or requires facilities which are not available, then for safety reasons please leave the job to your HARDI® dealer’s workshop.
ATTENTION!
Clean sprayers are safe sprayers.
Clean sprayers are ready for action.
Clean sprayers cannot be damaged by pesticides and their solvents.
Guidelines
1. Read the whole chemical label. Take note of any particular instructions regarding recommended protective clothing,
deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures are given, follow them
closely.
2. Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods, etc.
Contact the appropriate department, e.g. Dept. of Agriculture.
3. Pesticide washings can usually be sprayed out on a soakaway. This is an area of ground that is not used for cropping.
You must avoid seepage or runoff of residue into streams, water courses, ditches, wells, springs, etc. The washings from
the cleaning area must not enter sewers. Drainage must lead to an approved soakaway.
4. Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining spray liquid.
5. It is good practice to clean the sprayer immediately after use and thereby render the sprayer safe and ready for the
next application. This also prolongs the life of the components.
6. It is sometimes necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weather
becomes suitable for spraying again. Unauthorized persons and animals must not have access to the sprayer under these
circumstances.
7. If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after use with a
suitable rust inhibitor.
5.10
Page 43
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 over the crop you have 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 sprayer and tractor externally. Use detergent if necessary.
4. Remove suction and pressure filters and clean. Be careful not to damage the mesh.
5. With the pump running, rinse the inside of the tank. Remember the tank roof. Rinse and operate all components and
any equipment that has been in contact with the chemical. Before opening the distribution valves and spraying the liquid out, decide whether this should be done on the crop again or on the soakaway.
6. After spraying the liquid out, stop the pump and fill the tank 1/2 full 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 in contact with all the components. Leave the
nozzles 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 chemicals used have a tendency to block nozzles and filters, remove and clean them immediately.
10. Replace all the filters and nozzles and store the sprayer. 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 when spraying diluted remaining liquid on the crop 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, it is recommended to lubricate the entire
machine.
Cleaning and maintenance of filters
Clean filters ensure:
• Sprayer components such as valves, diaphragms and operating unit are not hindered or damaged during operation.
• Nozzle blockages do not occur while spraying.
• Long life of the pump. A blocked suction filter will result in pump cavitation. The main filter protecting sprayer components is
the suction filter. Check it regularly.

Regular mainten ance
10 hours service - Suction filter
The suction filter is located on the left side of the sprayer near the
pump. Its primary purpose is to protect the pump from damage. It
contains an automatic shut off valve to allow the operator to clean
and service the filter with a full tank.
Turn the yellow handle counter-clockwise until it “pops out”. This
closes an internal valve to prevent the main tank from draining
when cleaning the filter. Unscrew the large plastic nut and remove
the lid. Remove the filter for cleaning, being very careful not to damage the O-ring of the filter lid. This would allow air to enter during
suction and cause rattling of hoses and continual pressure variations. To prevent this, it is advisable to lubricate the O-ring with vegetable oil before closing the lid. Finally, replace the yellow valve handle and lock into position to allow flow through the filter.
WARNING! The suction filter is one of the most important elements of the fluid circuit. The ability of the pump to
take in air correctly largely depends on how well the filter has been cleaned and maintained. It is necessary to
clean the filter after every working day in order to keep the filter free of blockage.
10 hours service - In-Line filter
Unscrew the filter bowl to inspect and clean the filter. When
reassembling, the O-ring should be lubricated with vegetable oil.
Alternative filter meshes are available. See section on Technical specifications - Filters and nozzles.
10 hours service - Transmission shaft
The universal joints and ball bearings should be lubricated with
grease at the points (A) every 10 hours.

10 hours service - Spraying circuit
Fill with clean water, operate all functions and check for leaks using higher spray pressure than normal. Check nozzle
spray patterns visually using clean water.
50 hours service - Transmission shaft
Separate the two halves and grease (B) every 50 hours. Lubricate
points (C) with oil. Check function and condition of the transmission
shaft protection guard. Replace possible damaged parts.
50 hours service - Diaphragm pump
Grease the pump after every 50 hours of use or once a month.
WARNING! A lack of grease in the pump could cause it to
overheat and permanently damage internal parts.
50 hours service - Mechanical clutch
The function of the clutch is to transfer power from the pump into
the gearbox. It consists of two pinions (1) and a double chain (2)
which holds them together. The chain must be greased every 50
hours to avoid unnecessary wear.
When the chain is worn, it is recommended to change all parts, as a
new chain on worn pinions will wear faster.
50 hours service - Filters and fittings
Check the filters after 50 hours of use. Make sure to carefully inspect the mesh. If it is not in perfect condition, the filter
will not be effective. Replace the mesh with a new one.
Each time you dismantle a fitting to check the condition of a seal or for any reason, remember to lubricate the seal with
vegetable oil to avoid twisting or damaging the seal when putting the fitting back in place.
ATTENTION! A broken O-ring or seal in the suction circuit will cause the pump to suck in air and create large pressure variations and shaking hoses.

Off-season storage
Off-season storage program
When the spraying season is over, you should devote some extra time to the sprayer. If chemical residue is left over in the
sprayer for longer periods, it can reduce the life of the individual components. To preserve the sprayer intact and to protect the components, carry out following off-season storage program.
1. Clean the sprayer completely - inside and outside - as described in “Cleaning”in the “Operation”section. Make sure that
all valves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so
no chemical residue is left in the sprayer.
2. Replace possible damaged seals and repair possible leaks.
3. Empty the sprayer completely and let the pump work for a few minutes. Operate all valves and handles to drain as
much water off the spraying circuit as possible. Let the pump run until air is coming out of all nozzles.
4. Pour appr. 3 gal. (11 liters) anti-freeze mixture consisting of 1/3 automotive anti-freeze and 2/3 water into the tank.
5. Engage the pump and operate all valves and functions on the MANIFOLD, operating unit, etc. allowing the anti-freeze
mixture to be distributed around the entire circuit. Open the operating unit main on/off valve and distribution valves so
the anti-freeze is sprayed through the nozzles as well. The anti-freeze will also prevent O-rings, seals, diaphragms etc.
from drying out.
6. Lubricate all lubricating points according to the lubricating scheme - regardless of intervals stated.
7. When the sprayer is dry, remove rust from possible scratches or damages in the paint and touch up the paint.
8. Remove the glycerine-filled pressure gauges and store them frost free in vertical position.
9. Apply a thin layer of anti-corrosion oil (e.g. SHELL ENSIS FLUID, CASTROL RUSTILLO or similar) on all metal parts. Avoid
oil on rubber parts, hoses and tires.
10. Relieve pressure from all hydraulic functions.
11. Wipe hydraulic snap-couplers clean and fit the dust caps.
12. Apply grease on all hydraulic ram piston rods which are not fully retracted in the barrel to protect against corrosion.
13. To protect against dust the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.
Preparing the sprayer for use after storage
After a storage period the sprayer should be prepared for the next season the following way:
1. Remove the cover.
2. Wipe off the grease from hydraulic ram piston rods.
3. Fit the pressure gauges again. Seal with Teflon tape.
4. Connect the sprayer to the tractor including hydraulics.
5. Check all hydraulic functions.

Operational problems
General info
In cases where breakdowns have occurred, the same factors always seem to come into play:
1. Minor leaks on the suction side of the pump will reduce the pump capacity or stop the suction completely.
2. A clogged suction filter will hinder or prevent suction so that the pump does not operate satisfactorily.
3. Clogged up pressure filters will result in increasing pressure at the pressure gauge but lower pressure at the nozzles.
4. Foreign bodies stuck in the pump valves with the result that these cannot close tightly against the valve seat. This
reduces pump efficiency.
5. Poorly reassembled pumps, especially diaphragm covers, will allow the pump to suck air resulting in reduced or no
capacity.
6. Hydraulic components that are contaminated with dirt result in rapid wear to the hydraulic system.
Therefore ALWAYS check:
1. Suction, pressure and nozzle filters 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. Correct dosage depends on it.
5. Operating unit functions properly. Use clean water to check.
6. Hydraulic components are maintained clean.
