Welcome letter
Dear Owner,
Thank you for purchasing a HARDI® product and welcome to the ever-increasing family of HARDI® sprayer owners.
Our sprayers and accessories are rapidly becoming a familiar sight on North American farms. We believe that this results
from growers becoming increasingly conscious of crop protection input costs and the vital need for cost effective spray
application equipment.
Please take the time to thoroughly read the Operator’s Manual before using your equipment. You will find many helpful
hints as well as important safety and operation information.
Some of the features on your HARDI® sprayer were suggested by growers. There is no substitute for “on farm” experience
and we invite your comments and suggestions. If any portion of this instruction book remains unclear after reading it,
contact your HARDI® dealer or service personnel for further explanation before using the equipment.
For Product, Service or Warranty Information:
- Please contact your local HARDI® dealer.
To contact HARDI® directly:
- Please use the HARDI® Customer Service number: 1-866-770-7063
- Or send your email to [email protected]

This symbol means DANGER. Be very alert as your safety is involved!
Read and understand this instruction book before using the equipment. It is equally important that other opera-
tors of this equipment read and understand this book.
Local law may demand that the operator is certified to use spray equipment. Adhere to the law.
The tractor P.T.O. should never exceed 540 r.pm. as there is grave danger of causing the air kit to explode.
Wear protective clothing.
Rinse and wash equipment after use and before servicing.
Never service or repair the equipment while it is operating.
Always replace all safety devices or shields immediately after servicing.
Do not eat, drink or smoke while spraying or working with contaminated equipment.
Wash and change clothes after spraying. Wash tools if they have become contaminated.
This symbol means WARNING. Be alert as your safety can be involved!
Note the following recommended precautions and safe operating practices.
This symbol means ATTENTION. This guides to better, easier and safer operation of your sprayer!
General info
Operator safety
2 - Safety notes
In case of poisoning, immediately seek medical advice. Remember to identify chemicals used.
Keep children away from the equipment.
Pressure test with clean water prior to filling with chemicals.

2 - Safety notes
2.2
Keep away from the air inlet and outlet while the fan is on. Some objects (small stones, etc.) may be expelled by
the fan.
Do not attempt to enter the tank.
The safety and efficiency of this machine depends entirely
on the care it receives. The first important step is to read
carefully and pay attention to this instruction manual which
contains essential information on the efficient use and
maintenance of this high quality product.
As this instruction manual includes all the HARDI® ZENIT
axial, pneumatic and hydropneumatic models, please pay
special attention to the paragraphs dealing with the model
you have acquired.
This manual should be read along with that of “Mistblowing
Technique” (provided with the equipment) so that you can
obtain the best possible results.
This product line is very versatile due to the large range of optional extras available and their possible combina-
tions. The most commonly used technical data for air flow, power consumption and directions, is included in this
manual. Please contact your nearest HARDI® dealer if you need additional information.
Tractor driver’s seat is the intended working place during operation.
If any portion of this instruction book remains unclear after reading it, contact your HARDI® dealer for further
explanation before using the equipment.
No persons are allowed in the operations area of the sprayer.

Identification plates
The HARDI® ZENIT sprayer is designed for the application of chemical crop protection products and liquid fertilizers. This
equipment may only be used for this purpose. Using the sprayer for any other purpose is not allowed.
Even if no local law requires that the operator must be certified to use the spray equipment, it is strongly recommended
to be trained in correct plant protection and in safe handling of plant protection chemicals to avoid unnecessary risk for
persons and the environment when doing the spray job.
Use of the ZENITsprayer
The serial number plate is riveted onto the left hand side of the
frame, indicating the make, model and serial number of the sprayer.
The frame is manufactured with a tubular profile which provides great durability and resistance to breakages and vibra-
tions. To protect it from corrosion, it is sanded down and covered with a layer of special paint that contains a
polyurethane bi-component with anti-corrosion additives and protection against ultraviolet rays.
The tank is made of medium-density polyethylene with ultraviolet filters, it has smooth, rounded surfaces that facilitate
agitation and cleaning. Range of volumes: 105 gal. (400 Liters) and 155 gal. (600 Liters).

ATTENTION! Only the function in use should be open - always close valve when function is no longer needed.
ATTENTION! If a MANIFOLD valve is too tight to operate - or too loose (= liquid leakage) - the valve needs to be
serviced. Please see the “Maintenance” section for further information.
The MANIFOLD valve is equipped with symbol decals located on the disc for easy identification and operation. A function
is activated by turning the handle towards the desired function symbol.
Valvesand symbols
HC/1 or HC/2 Hydraulic control
Liquid system
The HC/1 or HC/2 hydraulic control consists of a MANIFOLD valve (A)
for operating agitation and the powder mixer, a manual pressure
regulator (B) with built-in safety valve, and a manifold pressure
gauge (C). The blower nozzles are operated with hydraulically con-
trolled section valves using the tractor hydraulics. All of these con-
trols are conveniently mounted in the control bracket located on the
front of the sprayer.
BK/2 Manual control
The BK/2 manual control consists of a Master On/Off valve (A), blow-
er nozzle distribution valves (B) with pressure equalization, manual
pressure adjustment valve (C), pressure filter (D), 2-1/2” pressure
gauge (E) and HARDI-MATIC. The HARDI-MATIC is a mechanical rate
controller that ensures a constant volume of spray solution per acre
at varying speeds in the same gear.
Agitation and the powder mixer are operated with the distribution
valves (F) located next to the safety valve (G).

3 - Description
3.4
Safety valve (BK units)
The safety valve acts like a fuse when the circuit carries out an oper-
ation that causes a sudden increase in pressure.
This valve normally keeps the return to tank in a closed position by
way of a spring and washer. When the amount of pressure in the cir-
cuit is above the maximum allowed for the valve, this opens and
allows the flow to return.
The valve opens at 220 psi (15 bar).
Do not remove the safety valve from the liquid circuit as this could put your safety at risk.
Diaphragm pump with 2 diaphragms, model 321, with easily accessible valves and diaphragms. Standard = 540 r.p.m (6
splines).
Pump
Pressure damper
To avoid the vibrations caused by pressure pulses in the liquid cir-
cuit, the 321 pumps are fitted with a pressure damper. The air pres-
sure in the damper is preset at the factory. If adjustment is desired,
see “Operation” section for adjustment procedures.
