NOTE. Your safety is involved so be alert!
Note the following recommended precautions and safe operating
practices.
Read and understand this instruction book before using the
equipment. It is equally important that other operators of this
equipment read and understand this book.
Local law may demand that the operator be certified to use spray
equipment. Adhere to the law.
Pressure test with clean water prior to filling with chemicals.
Wear protective clothing.
Rinse and wash equipment after use and before servicing.
Depressurize equipment after use and before servicing.
Never service or repair the equipment whilst it is operating.
Disconnect electrical power before servicing.
Always replace all safety devices or shields immediately after
servicing.
If an arc welder is used on the equipment or anything connected
to the equipment, disconnect power leads before welding. Re-
move all inflammable or explosive material from the area.
Do not eat, drink or smoke whilst spraying or working with contaminated equipment.
Wash and change clothes after spraying.
Wash tools if they have become contaminated.
In case of poisoning, seek doctor or ambulance. Remember to
identify chemicals used.
Keep children away from the equipment.
Do not attempt to enter the tank.
If any portion of this instruction book remains unclear after read-
ing it, contact your HARDI dealer for further explanation before
using the equipment.

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 BL 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.
HARDI INTERNATIONAL A/S reserve the right to make changes in
design or to add new features without any obligation in relation to
implements purchased before or after such changes.
Description
The Hardi BL models consist of a pump, frame with tank of 200 or 300
litre capacity with basket filter, M-70 operating unit and 6 or 8 metre SB
booms.
The design of 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, made of impact-proof and chemical resistant polyethylene,
has a purposeful design with no sharp edges for easy cleaning.
A suction filter is located inside the tank at the sump.
The M-70 operating unit consists of; on/off function, pressure regulation valve with pressure gauge and distribution valves for closing of
spray boom sections.
The SB boom is bolted to the tank frame and is fitted with spring
loaded breakaways at the pivots.
An identification plate fitted on the frame indicates model, year of
production and serial number, and country of origin.

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.
See section on Technical specifications.
Generally it is recommended to:
1. Add ballast to front of tractor.
2. Increase tyre pressure (see
tractor instruction book).
3. Travel at slower speeds when
driving with a full tank.
(The tractor will have decreased
braking efficiency.)
4. Be careful when filling/lifting the
sprayer the first time.
The pump is mounted directly
to the tractor P.T.O.
1. Undo the 2 allen screws * on
coupling and remove key.
2. Slide pump onto P.T.O.
shaft.
3. Replace key and tighten
allen screws.
4. Secure pump with supplied
chains to prevent rotation.
*
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
T153-0006
Operation of the boom
Remove boom transport lock pin (8 metre
only). 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 Re-adjustment of the boom)
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.
In crops 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
preset 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.

Adjustment of the operating unit
1. Turn main on/off handle (1) to off position A.
2. Set all hand levers on the distribution valve (2) to spraying position A.
3. Put the tractor in neutral and set the engine revolutions and thereby
the number of revolutions of the pump corresponding to the intended
travelling speed. Remember the number of revolutions on the P.T.O.
must be kept between 300-600 r/min.
4. Turn main on/off handle (1) to spraying position B.
5. Now turn the pressure regulating valve (3) to until the required
pressure is indicated on the pressure gauge.
6. Operating the control unit while driving:
To close the entire boom, turn the handle (1) to position A. This takes
the pressure off the pump. The liquid will then return to the tank via the
return system.
8
The diaphragm anti-drip valves ensure instantaneous closing of all
nozzles. In order to close part of the boom, move lever (2) of the
distribution valve to position B (off position) for the section or sections
to be closed. Note that the pressure will rise and readjustment will be
necessary.
Drain valve operation
A drain valve cap is located under the tank. Unsrew it to drain tank. Be
careful not to loose the seal.
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 - see Spray Technique book.
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 cavita-
tion.
The main filter protecting sprayer components is the suction filter
inside the tank at the sump. Check it regularly.
Also regularly check nozzle filters.

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.
