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 application 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 ENGAGED - push and pull shaft until it locks.
WARNING: ROTATING TRANSMISSION SHAFTS WITHOUT PROTECTION 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.
6
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.
Note: The shaft must always have a minimum overlap 150 mm.
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.
7
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 transmission 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.
8
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 3point 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 2 to ON position A.
3.Set all hand levers 3 on the distribution valve to ON position A.
4.Turn the HARDI-MATIC valve 4 anti-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 4 so that the pressure gauge indicates
the recommended pressure.
10
ADJUSTMENT OF PRESSURE EQUALIZATION:
7.Place the first lever 3 on 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.
10. Operating the control unit while driving:
To stop the liquid flow to the boom turn the ON/OFF handle 2 to 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 3 of the
distribution valve to OFF position B for 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.
