Use of the mistblower
The HARDI mistblower is designed for applying crop protection chemicals. The equipment should only be used for this
purpose. The mistblower must not be used for any other purpose. If there is no special regulations requiring operators to
be certified, you must have received the appropriate training for correctly spraying crops and safely handling chemicals
to avoid unnecessary risks to persons and the environment while spraying.
Roadworthiness
When driving on public roads and other places where the road safety code or where there are other special rules and
regulations for marking and lights on machinery, the machine must be equipped to comply with these regulations.

Use of the mist blower
The HARDI mist blower is designed for applying chemical products used for crop protection. This equipment may only
be used for this purpose. The use of this equipment for other purposes is not allowed. If there is no special law in your
region which obliges the user to have a permit, it is recommended to be well-prepared for protecting crops in a correct
way and for handling chemical products safely so as to avoid unnecessary risks to people and the environment while
spraying takes place.
For environmental issues the air kit is offered with option to close either left or right side of the air stream from the
blower. These blinds, are mandatory in some sensitive areas, to avoid chemical contaminated air, blowing towards river
sides and water channels
Roadworthiness
When driving on public roads and other places where the road safety code or where there are other special rules and
regulations for marking and lights on machinery, the machine must be equipped to comply with these regulations.
ATTENTION! For models not fitted with brakes the maximum speed is 25 km/h and 40 km/h for those with. This
could vary according to local legislation. Contact your local authorities to find out the current maximum speed
limits.
Identification plate
The identification plate is located on the front right-hand side of the
machine and is riveted to the chassis. It indicates the make, model,
serial number, and date of manufacture.
The serial number is also engraved onto the chassis. The number is
found above the identification plate, as indicated in the picture. The
serial number consist of five digits.
Chassis
The monoblock cold-pressed metal chassis is highly durable and built to last under everyday use under extreme
conditions. It is manufactured using only the most advanced laser cutting and automated soldering processes. To protect
against corrosion it is coated with a polyurethane bi-component paint on top of a highly adherent, steel blasted base.

Tank
The main tank made of impact-proof, UV-resistant and chemical resistant polyethylene, has a purposeful design with
no sharp corners for easy cleaning. Nominal contents are1000, 1500, 2000 or 3000 l. A large, easy to read tank contents
indicator is placed on the front - right-hand side and another one is placed on the left side. First one is visible from the
tractor cabin. The filling hole is accessible from the left-hand side. This ensures an easy access for the filling of spray liquid,
cleaning of the tank, etc. The mistblower is equipped with a clean water tank integrated with the main tank design.

Liquid system
General information
All the suction system functions are operated via a 3-way valve. The pressure valve is also to be found in the pressure
circuit. The low pressure circuit is called HLC (Hardi Liquid Circuit).
The liquid circuit
Consists of a manifold system in the working zone (front part) where pressure manifold receives liquid from the pump,
and distributes to the different options on the sprayer: to the operating unit, to the TurboFiller, to the bottle cleaner, to
the Powder mixer in strainer etc., all according to configuration of options. The suction manifold in same area allows
suction from main tank, rinsing tank or external water source, if fitted, depending on the configuration.
The pressure side of the liquid circuit is fitted with a safety valve to protect the circuit against misuse of excessive
pressure. See chapter “Safety valve”
Diaphragm pump
Pumps with a diaphragm: Models 321/10 (max. 20 bar) or 363/7 (max. 20 bar)
They are low pressure and robustly built. Use only grease for lubrication. The 363 model has six diaphragms and the 321
has two. This type of pump is self-priming, works without oil and can run dry as long as necessary.
Valves
The suction valve is located above the pump and is used to select
where to suck liquid from. Either suction from the main tank for
spraying or from the rinse tank for internal cleaning of the liquid circuit.
The function is selected by turning the handle of the valve towards the
desired function.
ATTENTION! If one of the handles is too tight - or too loose
(= liquid loss) - the valve needs to be serviced. For more
information, see section on “Maintenance”.
Valves and symbols
The valves are identified by coloured discs fitted on the valves themselves. The symbols correspond to the optional
accessories, and are located on the discs for quick identification and handling. To activate/open a function, turn the lever
to the desired function.
ATTENTION: Only the functions to be used should be activated – the other valves should always be kept closed.
ATTENTION: If the handle of a MANIFOLD valve is too tight – or too loose (loss of fluid)– the valve needs to be
serviced. For more information, see the section on ‘Maintenance’.

Manifold system
The pressure circuit HLC (Hardi Liquid Circuit) is used with diaphragm
pumps. The HLC distributor has three mechanical valves.
Valve (A) operates the agitator.
Valve (B) activates the powder mixer which flushes powder chemicals
through the tank strainer.
Valve (C) activates the rotating rinsing nozzle for rinsing the main tank
inside when the liquid circuit is rinsed with clean water.
Each function is identified by a pictorial symbol. Valves (A) and (B) are
optional.
Safety valves
The safety valve protects the liquid circuit against over pressure in the
event of failures or clogged lines.
If the spring-loaded safety valve opens the liquid is lead back to tank
via hose (A).
The safety valve opens at15 bar.
DANGER! Do not remove, bypass or block safety valve from the
liquid circuit as this could put your safety at risk.

Blue valve – Blue disc = Return valve
Towards agitation Towards the suction pump
The position of the return MANIFOLD valve determines where the
excess flow from the fluid circuit goes. When the arrow on the handle
points to a symbol, the excess fluid will be fully sent towards that
function (the example shows agitation). This valve does not have the ‘0’
position.
Pressure pulsation damper
The 321 pump is fitted with a pulsation damper on suction and
pressure sides. The pressure side damper is pressureized. The dampers
will reduce pulsations and secure an even flow from the pump.
The pressuredamper should be inflatedto the pressure shown in the

Axial blower units
Technical information
The air kits fitted on the HARDI ZATURN mist blowers are the AG820 and AG920, both having a polyethylene housing
and fan blades made of a hardened synthetic material. Their aerodynamic shape offer a high quantity and perfect air
distribution, low noise levels and low power consumption when adjusted to standard levels. The fan clutch enables a
smooth start and stop.
EF820, EF920, AB750, AB820, AB920, AG820 and AG920
The air kits are fitted with a grid with air guides at the air intake, which forms the air flow before reaching the fan, to
decrease the imbalance in the airflow. The fan is either 820 or 920 mm of diameter and is fitted with blades made of a
hardened synthetic material. This reduces the power consumption to a minimum as a result of low material density.
There is a channel between the air intake and the cone of the air kit which increases the air speed through the outlet,
and ensures that a high uniformity in air distribution is achieved.
