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 BOSS (BS) and HERON (HR) 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.
Description
The HARDI BS/HR sprayer is for the application of plant protection
chemicals. They consist of pump, operating unit, frame with tank and
spray boom.
The design of the diaphragm pump is simple, with easily accessible
diaphragms and valves that ensures liquid does not contact the vital
parts of the pump.
The tank, made of impact-proof and chemical resistant polyethylene,
has a purposeful design with no sharp corners, for easy cleaning.
The BK operating unit consists of; pressure agitator valve, safety valve,
main ON/OFF valve, pressure filter with pressure gauge, distribution valves
with pressure equalization and HARDI-MATIC pressure control valve.
HARDI-MATIC ensures a constant volume per hectare of the liquid
(l/ha) at varying speed in the same gear when the number of P.T.O. revolutions is between 300-600 r/min (800-1100 r/min for 1202/6.0 pumps).
The manually folded 6, 8 or 10 metre SB spray boom is fitted. It is
fitted with a spring loaded breakaway at the pivots and TRIPLET
SNAP-FIT nozzle bodies with COLOR TIP nozzles.
Identification plates
An identification plate fitted on the frame and pump is to indicate
model, year of production with 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 BS 300 sprayer is designed for Cushman and Jacobsen tractors
and fitting brackets must be used. For other tractors special hitching
brackets must be manufactured.
T056-0001
The BS 800 sprayer is designed for TORO Workman 3200/3300.
The HR 800 sprayer can be connected to the tractor drawbar. The
standard drawbar is forked. Alternatively, a drawbar with ball hitch can
be supplied. Max driving speed for HR 800 is 25 km/h.
The standard pump is made for 540 r/min PTO. An alternative is model
1202 pump for 1000 r/min PTO.

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
facillitate spline alignement, 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 CV-joints 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 meter.
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.
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 short-
est distance between the tractor and sprayer pump P.T.O. shafts.
2. Stop engine and remove ignition key.
T259-0004

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 necesary to shorten the shaft. Mark the protection guards.
T259-0004
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.
T259-0005
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.
T259-0007
7
Mechanical remote control - HR only
The operating unit remote control is fitted at a convenient place in the
tractor cabin.
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 the lights on implements, you should observe these and equip
implements accordingly.
Operating instructions
Filling the 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 syphoned back and contaminate
the water supply lines, plant and well.
8
Unfolding and folding the boom
The boom is operated as follows:
1. Remove boom transport
lock pins A.
2. Swing the boom down.
When unfolding (or folding)
the initial force to release
the spring loaded breakaway will be higher than the
actual unfolding/folding.
CAUTION: The breakaway
must be correctly tensioned
and lubricated.
(See section on Re-adjustment of the boom).
3. Unfold the outer sections.
Do not let the outer sections fall into place.
4. Reverse procedure to fold.
A
Boom height
Correct boom height is very important in order to obtain optimum distribution of the liquid (see “Spray Technique” book).
The boom height can be manually adjusted by removing the 4 bolts
keeping the boom on the frame.
NOTE: This is best done by 2 persons or by means of a hoist.
Pulsation damper
The air pressure in the pulsation damper is factory preset at 2 bar to cover 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. Turn the TRIPLET nozzle bodies to the
suitable nozzle for the spray purpose. Make sure that all nozzles are
the same type and capacity. See “Spray Technique” book.
2. Open or close lever 1 depending on whether pressure agitation is
required. (Remember pressure agitation takes 5% to 10% of pump
output).
3. Turn main ON/OFF handle 2 to ON position A.
4. Set all hand levers 3 on the distribution valve to ON position A.
5. Turn the HARDI-MATIC valve 4 anti-clockwise to its extreme position.
6. 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: For units with 540 r/min P.T.O., the revolutions must be kept
between 300-600 r/min.
NOTE: For units with 1000 r/min P.T.O., the revolutions must be
kept between 800-1100 r/min.
7. Adjust the HARDI-MATIC valve 4 so that the pressure gauge indi-
cates the recommended pressure.
T020-0025
10
ADJUSTMENT OF PRESSURE EQUALIZATION:
8. Place the first lever 3 on the distribution valve in OFF position B.
9. Turn the adjusting screw 5 until the pressure gauge again shows the
same pressure.
10.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.
OPERATING THE CONTROL UNIT WHILE DRIVING:
11.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.
OPERATING THE EXTRA VALVE
12.A spray gun can be connected to the control unit. When using this
function, set hand levers 3 for the boom section to OFF position B.
Screw the adjusting screws 5 in to prevent liquid returing to the tank.
Set hand lever 6 to ON position A.

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
instructions 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, eg. 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.
12
It is sometimes necessary to leave spray liquid in the tank for short
periods, eg. 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.
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
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. 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, eg. 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.
If fitted the Self-Cleaning Filter can be flushed by removing the
bypass hose from the bottom of the filter. Stop the pump and remove the hose. Start the pump for a few seconds to flush filter. Be
careful not to loose the restrictor nozzle.
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. Check also for
sediment on the pressure side of the safety valve for the Self-Cleaning Filter.
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.
13
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.
Suction filter
The main filter protecting sprayer components is the suction filter.
Check it regularly.
The BS 300 sprayer has a suction filter placed in the bottom of the tank.
The BS/HR 800 has a suction filter placed in the top of the tank.
BK Pressure filter / In Line Filters (if fitted)
The BK operating unit has an in-built 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.
Alternative filters are available. See section on Technical specifications
- Filters and nozzles.
14
Lubrication
Recommended lubrication is shown in following table. Use ball bearing
grease (lithium grease No. 2).
Note: If the sprayers are cleaned with a high pressure cleaner or fertilizer has been used, we recommend lubrication of all sections and all
metal parts by means of corrosion protective oil.

Re-adjustment of the boom
After having used the sprayer for some days the boom should be
adjusted according to the following instructions:
Carry adjustments out in the following order.
NOTE: Tractor and sprayer must be on level ground.
Sprayer must be lubricated. See section on Lubrication.
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 too tight, it will
not function. If it is too loose, it will
yaw (forward and back movement).
Slacken screw nut A to decrease
breakaway resistance. Do not
tighten excessively; better too
loose than too tight. Again minor
adjustments in the field may be
necessary.
Ensure also channel bolts B are
tight.
C
18
Outer section (8 and 10 m only)
The hinge should be firm. If too
tight it is difficult to fold. To adjust, tighten or loosen nuts C.
Recommended tyre pressure (only HR)
The tyres should not run under-inflated. This only promotes instability
and rapid wear.
Tyre size : 26" x 12"
Pressure :1.6 bar (24 p.s.i.)
The pressure is specified for a full loaded trailer.
Remember it is easier to let off a little pressure for a specific use than
to re-inflate a tyre in mid-field.
Wheel nuts and bearings (only HR)
Check wheel nut tension after the first 8 working hours, hereafter every
50 hours.
Check roller bearing slack after the first 8 hours and 50 hours.
Thereafter every 100 hours.
If necessary, adjust as follows
1. Jack wheel up. It is best to remove the wheel.
2. Remove hub cap A and split pin B.
3. Shaft nut C is tightened until slight
rotation resistance of drum is noted.
4. Now loosen shaft nut until first split
pin hole is visible.
5. Insert split pin and replace hub cap.
After 1000 hours or once a year, the
axle bearings are greased.
Changing of valves and diaphragms
Valves
Remove valve cover 1. Before changing the valves 2 note their orientation so they are replaced correctly.
It is recommended to use new gaskets 3 when changing or checking
the valves.
19
Diaphragms
Remove the diaphragm cover 4. 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. Reassemble with the following torque setting.
Pump Valve cover Diaphragm Diaphragm
Model Nm cover Nm bolt Nm
1302 45 50 25
1202 70 70 60
1 Nm = 0.74 ft-lb
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.
A
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
T199-0001
20
Therefore, in case of leaks: DO NOT overtighten. Disassemble, check
condition and position of O-ring or gasket, clean lubricate and reassemble. The O-ring should be lubricated ALL THE WAY ROUND
before fitting on to the nozzle tube.
For radial connections only hand tighten.
For axial connections, a little me-
chanical leverage may be used.
T199-0002
Off-season storage
When the spraying season is over you should devote some extra time
to the sprayer before it is stored.
Hoses
Check that none of the hoses are cut 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 replace them if there is any
doubt about the durability.
Paint
Some chemicals are very rough 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 section on Cleaning the sprayer.
Transmission shaft
Check that the shaft fullfils its security purpose, e.g. that shields and
protective tubes are intact.
Anti-freeze precaution
If the sprayer is not stored in a frost free place you should take the
following precautions: Put at least 10 litres of 33% anti-freeze mixture
in the tank and let the pump run a few minutes so that the entire system including spray hose are filled. The anti-freeze solution also hinders the O-rings and gaskets from drying out.
Remove the glycerine filled pressure gauge and store it frost free in
vertical position.
21
Operational problems
In cases where breakdowns have occurred the same factors always
seem to come into play:
• Minor leaks on the suction side of the pump will reduce the pump
capacity or stop the suction completely.
• A clogged suction filter will hinder or prevent suction so that the
pump does not operate satisfactorily.
• Clogged up pressure filters will result in increasing pressure at the
pressure gauge but lower pressure at the nozzles.
• Foreign bodies stuck in the pump valves with the result that these
cannot close tightly against the valve seat. This reduces pump
efficiency.
• Poorly reassembled pumps, especially diaphragm covers will allow
the pump to suck air resulting in reduced or no capacity.
Therefore ALWAYS check
1. That 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.
