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 KS, TR, PU, UN, SAFARI (SR),
GEMINI (GN) and COLT (CT) 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
HARDI sprayers are for the application of plant protection chemicals.
They consist of electric or petrol driven pump, operating unit, frame
with fixed track width (KS/TR/SR/GN) or frame (PU/CT) with or without
adjusting brackets and polyethylene tank.
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.
If a pressure up to 40 bar is required, the P3L piston pump is the fitted.
The tank, made of impact-proof and chemical resistant polyethylene,
has a purposeful design with no sharp corners, for easy cleaning.
The M-600/600HT, N-2 or BK operating unit consists of; main ON/OFF
valve, pressure gauge, distribution valves and pressure control valve.
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.

Before operation
Electric motor
If the sprayer is equipped with an electric motor it must be connected
by the authorized electrician according to the local law. Adhere to the
law.
Petrol engine
If the sprayer is equipped with a petrol engine, see enclosed instruction
manual on the engine regarding petrol, oil change and maintenance. If
any doubt, contact Briggs & Stratton service personnel.
WARNING: To prevent accidents remove the high tension lead from
the engine before servicing the engine or other parts of the sprayer.
WARNING: REMEMBER SUFFICIENT VENTILATION - NEVER
WORK IN CLOSED ROOMS.
Exhaust gas containing carbon monoxide has no odour but is very
dangerous.
WARNING: NEVER FILL ON PETROL WHEN THE ENGINE IS
WORKING.
Do not spill petrol on a hot engine. This may cause an explosion and
serious injury.

Pump
Check the pump belts are tight and the protection screen is in good
condition according to local law.
Is the pump the piston type
check oil level and fill on SAE
20/40 HD if necessary.
The oil level must be between
min. and max. mark on the dip
stick (2). Furthermore, the P3L
has an outside sight glass (2).

6. To stop liquid flow to the spray lance turn main ON/OFF to pos. 1B,
then there will be no pressure in the sprayer and the capacity of the
whole pump is led through the by-pass to the tank.
NOTE: Higher working pressure means smaller drops = better
coverage, but increased risk of wind drift.
Adjustment of the BK controls
1. Fill the sprayer tank with clean water.
2. Start the engine.
3. Turn main ON/OFF handle to spraying position 1A.
4. Open the pressure agitation valve 3, if supplied (tight spring ten-
sion).
5. Open the distribution valves 4A.
6. Set the pressure control valve 2at 3 bar more than normal working
pressure to check possible leaks. Reduce the pressure to normal
working pressure.
7. Close the distribution valves 4B one by one. Adjust on pressure
equalization valves 5if the pressure increases/drops.
8. Turn main ON/OFF and the capacity of the whole pump is led
through the by-pass to the tank.

NOTE: Higher working pressure means smaller drops = better cover-
age, but increased risk of wind drift.
Choice of nozzle size
If you want to change the standard nozzles of the spray lance by other
nozzles, it is very important that the pump is capable to feed the
nozzles wanted.
Spray Technique - see separate book.
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
agent, etc. Read the detergent and deactivating agent labels. If clean-
ing procedures are given follow them closely.
Be familiar with local legislation regarding disposal of pesticide wash-
ings, mandatory decontamination methods, etc. Contact the appropri-
ate 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 seep-
age 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
periods, eg. overnight, or until the weather becomes suitable for

9
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 cannot be damaged by pesticides
and their solvents.
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 sprayer has a suction filter placed in the top of the tank.
BK Pressure filter
The BK operating unit has an built-in pressure filter. Unscrew the filter
bowl to inspect and clean the filter.
Alternative filters are available.
See section on Technical specifications - Filters and nozzles.
Lubrication
After 40 hours’ operation the diaphragm pump is lubricated with ball
bearing grease Lithium No. 2.

10
Check the pump belts daily - if tightening is necessary, loosen engine
mounts, move the engine and re-tighten.
If the engine is equipped with reducing gear please see enclosed
Briggs & Stratton instruction manual “Oil check, oil change/intervals
and oil qualities”.
Lubricate frequently the movable parts of the operating unit with
corrosion protective oil.
Change the oil of the piston pump for the first time after 50 hours’
operation and then every 150 hours or at least once a year. Fill 20/40
HD oil until it shows in the sight glass.
Be sure there is no play in the wheel bearings - use ball bearing
grease twice a year.
Check oil level of the petrol engine each day. Please see “Oil change”
Briggs & Stratton instruction book.
Off-season storage
When the spraying season is over you should devote some extra time
to the sprayer before it is stored.
Tyres
It is important frequently to check tyre pressure. The tyres should not
run under-inflated. This only promotes instability and rapid wear. See
section on Technical Specifications.
Hoses
Check that none of the hoses are caught or have sharp bends.
A leaky hose can cause 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 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.

11
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. The anti-freeze solution also hinders the O-rings and
gaskets from drying out.
Relieve the pressure regulating spring.
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.
• Unclean electric components causes poor connections.
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. Keep the electric components clean.
