Thank you for purchasing a HARDI® product and welcome to the everincreasing 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 application equipment.
Please take the time to thoroughly read the Operator’s Manual before
using your equipment. You will fi nd many helpful hints as well as
important safety and operation information.
Some of the features on your HARDI® NAVIGATOR Manifold 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.

The HARDI® Navigator 550M, 800M* and 1000M centrifugal models
consist of a hydraulic pump or P.T.O. driven pump with P.T.O. shaft,
frame with tank, ESC controls (Electric Control) and Manifold System.
The Navigator 550M model is available with either the hydraulic folding
Eagle™ SPB series spray boom available in 45', 50', 60' or 66' widths
or a manual fold boom (MB) available in 35', 40', 42', 45' or 50' widths.
The Navigator 800M*/1000M model is available with the hydraulic
folding Eagle™ SPC series spray boom available in 80' 88' or 90'
widths.
The tanks, made of impact proof and chemical resistant poly eth ylene,
have a purposeful design with rounded contours which allows for
efficient cleaning and draining. The tanks are designed with a large
deep sump, so that they can be completely emptied even when the
sprayer is used on slopes up to 15% inclination. A remote operated
valve drain is fi tted for effi cient draining.
The ESC control unit consists of: ON/OFF control, pressure regulating
valve, 2 1/2" pressure gauge and distribution valves with pressure
equalization.
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 centralized location.
The Eagle™ coil spring suspended 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 with a 'joystick' control handle. An optional electrical 'DH'
control for closed center hydraulics is available. Both versions require
single and double acting hy drau lic outlets on the tractor as well as a
12V connection for the HZ model. The MB (manual fold boom) offers
hydraulic height adjustment and hydraulic wing tilt as options.

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 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 hydraulic lever to operate the hydraulic driven pump, 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
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 should be working 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 unfolded.
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 fl ashing lights. Local regulations
may require installation of fl ashing warning lights.
14. Avoid injuries from high pressure fl uids penetrating the skin by
relieving system pressure before disconnecting hydraulics or other
lines. Ensure all fi ttings are tight before applying pressure to the
system.
15. Understand service procedures before undertaking any mainte-
nance. Never lubricate, service, or adjust the machine while it's
moving. Securely support any components before working on
them.
16. Keep all parts in good condition and properly installed. Fix dam-
aged parts immediately. Replace worn or broken parts. Remove
ex cessive buildup of grease, oil or debris.
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
specifi c 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 fi ll, fl ush, 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
no chance of children coming 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 fi ltered 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 fi rst aid kit and fi re extinguisher available at all times when
handling chemicals.
