We congratulate you for choosing a HARDI plant protection product. The
reliability and efficiency of this product depend on your care. The first step
is to carefully read and pay attention to this instruction book. It contains
essential information for the efficient use and long life of this quality product.
As the instruction book covers all JAZZ models, please
pay attention to the paragraphs dealing with precisely
your model. This book is to be read in conjunction with the
Spray Technique book.
Lifting points
When loading or unloading the sprayer from a truck or
lorry with a crane, use the lifting points as shown.
Description
The HARDI JAZZ tractor mounted sprayers are designed for the applica-
tion of pesticides and liquid fertilizers in parks, gardens and amenity areas.
They consist of a pump, a frame with tank of 200 litre capacity, BK 180
operating unit, a 6, 8 or 10 metre SB boom, 15 litre clean water tank,
transmission shaft and calibration kit
The diaphragm pump is simple, with easily accessible diaphragms and
valves that ensures liquid does not come in contact with the vital parts of
the pump.
The tank with basket filter is made of impact-proof and chemical resistant
polyethylene. It has a purposeful design with no sharp edges for easy
cleaning. A suction filter is located inside the tank at the sump. The
standard filling hose holder reduces the risk of mishaps at filling.
The BK 180 K operating unit consists of; agitator, safety valve, on/off
function, pressure filter with pressure gauge, distribution valves with
pressure equalization device, an extra valve for lance or spray gun and
HARDI-MATIC. A constant volume per hectare of the liquid at varying
speed in the same gear is ensured with HARDI-MATIC.
The SB boom is bolted to the tank frame and is fitted with spring loaded
breakaways at the pivots. The TRIPLET nozzle holders allow for quick
nozzle selection.

Identification plates
An identification plate fitted on the frame and pump is to indicate model,
serial number and country of origin. If ordering spare parts, inform your
dealer of these so the right model and version are described.

Connecting the sprayer
The sprayer is designed for three point suspension and is equipped with
22 mm pivots (category I).
WARNING: Note the weight of the sprayer. General recommendations are
as follows:
• Add ballast to front of tractor.
• Increase tyre pressure
(see tractor instruction book).
• Be careful when filling/lifting the sprayer for
the first time.
• Ensure the operating unit and tractor do not touch.
• Travel at slower speeds when driving with a full tank.
(The tractor braking effect will be reduced.)
Transmission shaft
Operator safety
To avoid accidents and personal injuries, note the following recommended
precautions and safe operation practices.
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.
When attaching the shaft, make sure that the snap lock is FULLY EN-
GAGED - push and pull shaft until it locks.
WARNING: ROTATING TRANSMISSION SHAFTS WITHOUT PROTEC-
TION GUARDS ARE FATAL
Always keep protection guards and chains intact and make sure that it
covers all rotating parts, including cross journals at each end of the shaft.
Do not use without protection guard.
Do not touch or stand on the transmission shaft when it is rotating - safety
distance: 1.5 metre.
Prevent protection guards from rotating by attaching the chains allowing
sufficient slack for turns.
Make sure that protection guards around tractor P.T.O. and implement
shaft is intact.

7
Always STOP ENGINE and remove the ignition key before carrying out
maintenance or repairs to the transmission shaft or implement.
Installation of transmission shaft
Initial installation of the shaft is done as follows:
1. Attach sprayer to tractor and set sprayer 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.
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.
Note: The shaft must always have a minimum overlap 150 mm.

8
6.Fit the shaft to tractor and sprayer
pump.
NOTE: Female part towards tractor.
Fit the chains to prevent the
protection guards to rotate with the
shaft.
7.To ensure long life of the transmis-
sion shaft, try to avoid working
angles greater than 15°.
8.Transmission shafts with cone
must be fitted by tightening the
Allen screw to a torque of 40 Nm.
Check again after 2 minutes use.
Rear lights (if fitted)
Connect plug for rear lights to the tractors 7-poled
socket and check that rear lights, stop lights and direction
indicators work properly before driving anywhere.
The wiring is in ISO accordance. See section on Technical specifications.
Roadworthyness
When driving on public roads and other areas where the highway code
applies, or areas where there are special rules and regulations for marking
and lights on implements, you should observe these and equip implements
accordingly.
Operating instructions
Filling the main tank
Water is filled into the tank by removing the tank lid located at right hand
side of sprayer tank. It is recommended to use as clean water 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 lead into the tank and the
water pressure drops at the water supply
plant, chemicals may be siphoned back
and contaminate the water supply lines,
plant and well.

9
Operation of the boom
Remove boom transport lock pin if fitted.
When unfolding (or folding) the initial force
to release the spring loaded breakaways
will be higher than the actual unfolding/
folding.
CAUTION: The breakaways must be
correctly tensioned and lubricated.
(see section on Boom breakaway)
Replace boom transport lock pin when
driving with folded boom.
Boom height
Correct boom height is very important in order to achieve the most optimal
spray pattern. (See Spray Technique book).
Small adjustments of the boom height can usually be made with the 3-
point suspension from the tractor - raising or lowering the sprayer.
On grounds where greater adjustments are needed the boom height can
be changed manually by removing the 4 bolts holding the boom to the
frame.
Note: This is best done by 2 persons or with a mechanical hoist.
Pulsation damper
The air pressure in the pulsation damper is pre-set at
the factory to 2 bar. This covers spray working
pressures between 3 and 15 bar. When using spray
pressures outside this range, the air pressure should
be adjusted as shown in the diagram. The diagram is
also embossed on the damper.

1.Choose the correct nozzle. Make sure that all nozzles are the same
type and capacity. See “Spray Technique” book.
2.Turn main ON/OFF handle 2to ON position A.
3.Set all hand levers 3on the distribution valve to ON position A.
4.Turn the HARDI-MATIC valve 4anti-clockwise to its extreme position.
5.Put the tractor in neutral and adjust the P.T.O. thereby the number of
revolutions of the pump corresponding to the intended travelling speed.
Note: The P.T.O. revolutions must be kept between 300-600 r/min.
6.Adjust the HARDI-MATIC valve 4so that the pressure gauge indicates
the recommended pressure.
ADJUSTMENT OF PRESSURE EQUALIZATION:
7.Place the first lever 3on the distribution valve in OFF position B.
8.Turn the adjusting screw 5 until the pressure gauge again shows the
same pressure.
9.Adjust the other sections of the distribution valve in the same way.
Hereafter adjustment of pressure equalization will only be needed if you
change to nozzles of other capacities.

11
10. Operating the control unit while driving:
To stop the liquid flow to the boom turn the ON/OFF handle 2to OFF
position B. This returns the pump output to the tank through the return
system. The diaphragm anti-drip valves ensure instantaneous closing
of all nozzles.
To stop the liquid flow to one or more boom sections, turn lever 3of the
distribution valve to OFF position Bfor the section to be closed. The
pressure equalization ensures that the pressure does not rise in the
sections which are to remain open.
Drain valve operation
A drain valve cap is located under the tank. Unscrew it to drain tank. Be
careful not to loose the seal.
Spray Technique - see separate book.
Optional Extras - see separate books.

12
Maintenance
In order to derive full benefit from the sprayer for many years the following
few but important rules should be kept:
Cleaning the sprayer
Guidelines
Read the whole label of the chemical. Take note of any particular instruc-
tions regarding recommended protective clothing, deactivating agents, etc.
Read the detergent and deactivating agent labels. If cleaning procedures
are given, follow them closely.
Be familiar with local legislation regarding disposal of pesticides washings,
mandatory decontamination methods, etc. Contact the appropriate body,
e.g. Dept of Agriculture.
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
run-off of residues into streams, water courses, ditches, wells, springs, etc.
The washings from the cleaning area must not enter sewers. Drainage
must lead to a soakaway.
Cleaning starts with the calibration, as a well calibrated sprayer will ensure
the minimal amount of remaining spray liquid.
It is good practice to clean the sprayer immediately after use thereby
rendering the sprayer safe and ready for the next pesticide application.
This also prolongs the life of the components.
It is sometimes necessary to leave spray liquid in the tank for short peri-
ods, 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.
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.
Remember: Clean sprayers are safe sprayers.
Clean sprayers are ready for action.
Clean sprayers can not be damaged by pesticides and
their solvents.

13
Cleaning
1.Dilute remaining spray liquid in the tank with at least 10 parts water and
spray the liquid out in the field you have just sprayed.
NOTE: It is advisable to increase the forward speed (double if possible)
and reduce the pressure. For S4110 nozzles, pressure may be reduced
to 1.5 bar.
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 neces-
sary.
4.Remove tank and clean. Be careful not to damage the mesh. Replace
when the sprayer is completely clean.
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 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.
NOTE: If a cleaning procedure is given on the chemical label, follow it
closely.
7.Start the pump and operate all controls enabling the liquid to come in
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 pump run dry. Rinse inside of 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 now.
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.
NOTE: If the sprayer is cleaned with a high pressure cleaner we
recommend lubrication of the entire machine.

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 whilst spraying.
• Long life of pump. A blocked suction filter will result in pump cavitation.
The main filter protecting sprayer components is the suction filter inside
the tank at the sump. Check it regularly. Also regularly check nozzle filters.
BK Pressure filter / In Line Filters (if fitted)
The BK operating unit has a built-in pressure filter. Unscrew the filter bowl
to inspect and clean the filter.
The boom may be equipped with In Line Filters. Unscrew the filter bowl to
inspect and clean the filter.
Lubrication
Recommended lubrication is shown in following tables. Use ball bearing
grease (lithium grease No.2)
NOTE: If the sprayers are cleaned with a high pressure cleaner or it has
been used to spray fertilizer, we recommend lubrication of the entire
machine.

Re-adjustment of the boom
After having used the sprayer for some days the boom should be adjusted
as follows:
When adjusting the sprayer must be on level ground with unfolded boom.
Boom breakaway
The function of the breakaway is
to prevent or reduce boom
damage if it should strike an
object or the ground. If it is over-
tight, it will not function. If it is
too loose, it will yawn (forward
and back movement) under
spraying.
Lubricate coupling before
adjusting spring tension. Slacken screw nut Ato decrease breakaway
resistance. Do not overtighten; better to loose than over-tight. Again minor
adjustments in the field may be necessary.
Ensure also channel bolts Bare tight.
Outer section (8m boom)
The hinge should be firm. If
overtight it is difficult to fold. To
adjust, tighten or loosen nuts C.

Changing of valves and diaphragms
Valves
Dismantle valve compartment (1). Before changing the valves (2) note the
orientation of the valves so that they may be replaced correctly.
It is recommended to use new gaskets (3) when changing or checking the
valves.
Diaphragms
Remove the diaphragm cover (4) after having dismantled the valve com-
partment as indicated above. The diaphragm (5) may then be changed. If
fluids have reached the crankcase, re-grease the pump thoroughly. Check
also the drain hole at the bottom of the pump is not blocked.

Changing the ball seat in operating unit
If the main ON/OFF valve does not seal properly (dripping nozzles when
main ON/OFF valve is closed), the ball and seat should be
checked.
Remove the 2 bolts fixing the main ON/OFF-
pressure valve unit to the bracket, unscrew
the union nut A and pull the valve
away from the distribution
valves.
Check the ball for
sharp edges and
scratches, and check
the ball seat for cracks
and wear - replace if
necessary.
Nozzle tubes and fittings
Poor seals are usually caused by:
• Missing O-rings or gaskets
• Damaged or incorrectly seated O-rings
• Dry or deformed O-rings or gaskets
• Foreign bodies
Therefore, in case of leaks: DO NOT over-tighten.
Disassemble, check condition and position of O-
ring or gasket, clean lubricate and reassemble.
For radial connections only hand tighten them.
The O-ring to be lubricated ALL THE WAY ROUND before fitting on to the
nozzle tube.
For axial connections, a little
mechanical leverage may be used.

Replacement of transmission shaft protection guards
The replacement of defective protection guards is easy to do.
1. Remove bolt A, lock B and
grease nipple C. Twist universal
cross cover 1/4 turn and pull it
backwards.
2. Remove the synthetic bearings
and protection tube.
2a.Remove inner bush from
protection tube.
3. Assemble again in reverse
order, using new parts where
necessary. Remember to fit
chains again.
4. Grease bearings.
Use only genuine HARDI spare
parts to service the transmis-
sion shaft.
Replacement of transmission shaft cross journals.
1. Remove protection guard as
described previously.
2. Remove Seeger circlip rings
3. Press the cross journal
sidewards - use hammer and
mandrel if necessary.
4. Remove needle bearing cups
and cross journal can now be
removed.
5. Carefully remove needle bearing
cups from new cross journal and
install it in reverse order. Before
fitting the needle bearing cups
again, check that needles is
placed correctly. Avoid dust and
dirt in the new bearings.

20
Off-season storage
When the spraying season is over you should devote some extra time to
the sprayer before it is put away.
Hoses
Check that none of the hoses are caught or have sharp bends.
A leaky hose can give an annoying delay in the middle of the spraying job.
Therefore check all the hoses and change if there is any doubt about the
durability.
Paint
Some chemicals are very hard on paints. It is therefore well advised to
remove rust, if any, and then touch up the paint.
Tank
Check that no chemical residues are left from the last spraying. Chemical
residues must not be left in the tank for a long time. It will reduce the life of
the tank. See Cleaning the sprayer.
Anti-freeze precaution
If the sprayer is not stored in a frost-proof place you should take the
following precautions: Put at least 5 litres of 33% anti-freeze mixture in the
tank and let the pump run a few minutes so that the entire system includ-
ing spray hose are filled. Remove the glycerine filled pressure gauge and
store it frost free in vertical position.
The anti-freeze solution also hinders the O-rings and gaskets from drying
out.
