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.

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.

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
