HARDI MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL
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.
Please address your correspondence to the Service Manager at one of
these branches:
Sincerely,
Tom L. Kinzenbaw
President

1.0 INTRODUCTION
The HARDI MEGA models consist of a pump, frame with a tank that has
either 230 or 350 gallon capacities, ESC-Controls (Electric Control),
Manifold system, P.T.O. shaft and a 60' hydraulic folding Eagle series
spray boom. The 230 gallon model will mount directly to a category II & III
3-point hitch as well as to a category II and category III quick hitch. The
350 gallon model will mount directly to a category III 3-point hitch and
category III & category IIIN quick hitch. A pin kit is available for mounting
the 350 gallon to category II 3-point link arms.
The tank, made of impact-proof and chemical resistant polyethylene, has
a purposeful design with no sharp corners, for easy cleaning. A large,
easy to read tank contents indicator is placed in front of the tank. A step
and platform is placed at the right hand side of the sprayer for easy
access to the tank filling hole.
The ESC (electric control) unit consists of: on/off control valve, pressure
regulating valve, pressure gauge and distribution valves with pressure
equalization feature.
The "Manifold System" features color coded three way valves on suction
and pressure sides of the liquid control system. It allows for safe and
simple use of the sprayer and accessories from one position.
The Self-Cleaning Filter screens out impurities from the spray solution
which are recirculated back to the main tank while clean solution is
constantly being supplied to the boom.
The Eagle hydraulic series boom is available with either 3(HY model) or 5
(HZ model) hydraulic cylinders. The base version being the HY model,
includes boom height adjustment and fold/unfold features all controlled
from the tractor. The HZ model has all the same features as the HY
model but also includes individual wing tilt and fold as added features.
Both versions require single and double acting hydraulic outlets on the
tractor as well as a 12V connection for the HZ model.

RECOGNIZE SAFETY INFORMATION
This is the Safety-alert symbol. When you see
this symbol on your machine or in this manual,
be alert to the potential for personal injury.
Follow recommended precautions and safe
operating practices.
2.1 Follow Safety Instructions
- Carefully read all the safety messages in this manual and the safety
labels fitted to the machine. Keep safety labels in good condition.
Replace missing or damaged safety labels. Be sure that new
equipment components include any current safety labels. Replacement
safety labels are available from your authorized HARDI dealer.
- Learn how to operate the sprayer and how to use the controls prop
erly. Do not let anyone operate the sprayer without proper
instructions.
- Keep your sprayer in proper working condition. Unauthorized
modifications or use may impair the function and/or safety and affect
the machines life.
- If you do not understand any part of this manual and need assistance,
please contact your authorized HARDI dealer.
2.2 Operating The Sprayer Safely
1.Read the complete manual carefully and become familiar with the
operation of the equipment before initial operation in each spraying
season. Failure to do so may result in possible over or under
application of spray solution which may drastically affect crop
production and/or lead to personal injury.
2. Before starting the engine on the tractor unit, be sure all operating
controls are in the off or neutral position, including but not limited to the
P.T.O. shaft and/or spray controls. Be sure the tractor power train is
disengaged.
3.Operate spray and boom functions only when seated in the Operator’s
seat.

2.2 Operating The Sprayer Safely (cont'd)
4. One of the most frequent causes of personal injury or death results
from persons falling off or being run over. Do not permit others to
ride on or in. Only one person - the operator - should be in the
tractor when in operation.
5. Before leaving the tractor seat, stop the engine, put all controls in
neutral, and put the transmission control lever in the park position or
neutral with the brakes locked. Read the tractor operations manual for
added safety precautions.
6. PTO driven equipment can cause serious injury. Before working on or
near the P.T.O. shaft, servicing or cleaning the equipment, put PTO
lever in the DISENGAGE position and stop the engine.
7. Do not fold or unfold boom near overhead wires. Serious injury or
death could result if contact is made with electric wires.
8. Keep hands, feet & clothing away from moving parts.
9. Wear relatively tight and belted clothing to prevent from being caught
on some part of the machine.
10. Slow down when turning especially with boom extended.
11. Always keep children away from your sprayer and/or tractor unit.
12. Before transporting the sprayer ensure that the boom is fully folded
and fully locked into transport position. Ensure all locking
devices are fully engaged whether hydraulic or mechanical.
13. Slow moving tractors and spray equipment can create a hazard when
on public roads. Avoid personal injury or death resulting from any
accidents by using flashing lights. Local regulations may require
installation of flashing warning lights.
14. Avoid injuries from high pressure fluids penetrating the skin by
relieving system pressure before disconnecting hydraulics or other
lines. Ensure all fittings are tight before applying pressure to the
system.

11
HARDI MEGA 230 / 350 CENTRIFUGAL OPERATORS MANUAL
2.2 Operating The Sprayer Safely (cont'd)
15. Understand service procedures before undertaking any
maintenance. Never lubricate, service, or adjust the machine while
its moving. Securely support any components before working on
them.
16. Keep all parts in good condition and properly installed. Fix damaged
parts immediately. Replace worn or broken parts. Remove excessive
buildup of grease, oil, or debri.
2.3 Handling Chemical Products Safely
1. Direct exposure to hazardous chemicals can cause serious injury.
These chemicals can include lubricants, coolants, paints, adhesives
and agricultural chemicals. Material safety data sheets (M.S.D.S.) are
available for all hazardous chemicals which inform the user of specific
details including, physical and health hazards, safety procedures, and
emergency response techniques.
2. Protective clothing such as rubber gloves, goggles, coveralls and
respirator must be worn while handling chemicals. All protective
clothing should be kept in excellent condition and cleaned regularly or
discarded.
3. If chemicals come in contact with any exposed skin areas, wash
immediately with clean water and detergent. Never place nozzle tips
or any other components that have been exposed to chemicals to lips
to blow out obstructions. Use a soft brush to clean spray nozzles.
4. Dedicate an area to fill, flush, calibrate and decontaminate sprayer
where chemicals will not drift or run off to contaminate people,
animals, vegetation, water supply, etc. Locate this area where there is
virtually no chance of children being in contact with this residue.
5. Decontaminate equipment used in mixing, transferring, and applying
chemicals after use. Follow the instructions on the chemical label for
the correct procedure required. Wash spray residue from outside of
the sprayer to prevent corrosion.

2.3 Handling Chemical Products Safely (cont'd)
6. Extreme care should be taken in measuring spray products. Powders
should be used in suitable sized packages or weighed accurately.
Liquids should be poured into a suitable graduated container. Keep
chemical containers low when pouring. Wear a filtered respirator and
let the wind blow away from you to avoid dust and/or splashes
contacting the skin or hair.
7. Store chemicals in a separate, plainly marked locked building. Keep
the chemical in its original container with the label intact.
8. Dispose all empty containers after rinsing in accordance with local
regulations & by-laws. Dispose of all unused chemicals and left over
fertilizer in an approved manner
9. Keep a first aid kit and fire extinguisher available at all times when
handling chemicals.
