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 chemical input costs and the vital need for
cost effective chemical 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 EAGLE 3PT boom 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

1.0 INTRODUCTION

The EAGLE 3-point boom is a fully suspended hydraulically operated
spray boom featuring self-stabilizing trapeze suspension with coil
springs and a shock absorber to control the rate of boom movement.

The 3-point hitch frame meets the requirements for mounting the
sprayer to a CAT II or CAT III 3 point hitch or CAT II or CAT III-N quick
hitch coupler. The Hitch frame has a pump mounting plate (for PTO
and hydraulic drive pumps) as well as provision for mounting control
units and other accessories.

The 48’ and 60’ EAGLE 3-point boom also has parking stands
attached to the center frame which allows the boom to freestand when
not in use.

Three versions of the EAGLE 3-point boom are available. The “HY”
features simultaneous boom wing folding. The “HT” features
simultaneous wing fold and individual wing tilt through three tractor
double acting outlets. The “HZ” features electric hydraulic wing fold
(same as “HY”) plus individual wing tilt. This will require two tractor
double acting outlets and a 12v power supply. The hydraulic hoses that
attach to the tractor are fitted with 1/2” NPT quick couplers.

The EAGLE 3-point boom can be equipped with either single Snap-fit
or triplet nozzle bodies. Two pump and control systems are available
as options to the 3-point EAGLE boom. The Diaphragm pump system
features a HARDI

®

361 Diaphragm pump and electric control unit with
HARDI-matic, a mechanical rate controller, and a self-cleaning
pressure filter. The Centrifugal pump system features a Ace 206
hydraulically driven pump with an electric control unit. Both systems
are complete with adjustable agitation, constant pressure feature, in­cab control box, system pressure gauge, and PTO shafts.

application of spray solution which may drastically affect crop
production 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.

10 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

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 on the
machine 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. P.T.O. driven equipment can cause serious injury. Before working
on or near the P.T.O. shaft, servicing or cleaning the equipment,
put P.T.O. 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 rests and stops. 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. Use flashing lights to avoid personal injury or
death resulting from any accidents. Local regulations may require
installation of 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.

15.

Understand service procedures before undertaking any
maintenance. Never lubricate, service, or adjust the spray boom
while it’s operating. 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 debris.

11HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

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 during operation. 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 mouth 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.

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.
