Introduction
New NAVIGATOR 1100 gallon with 100’ Eagle™ SPC (HZ) boom

5HARDI®New NAVIGATOR OPERATOR’S MANUAL
Description
Description
Frame
The frame is all steel construction. It has a strong
chemical and weather resistant powder coat. Screws,
nuts, etc. have been electrochemically treated to be
resistant to corrosion.
Adjustable wheel spacing
Allows infinite wheel spacing adjustment of 60” to 120”.
WARNING! Use extreme caution with narrower
wheel spacing (close to 60”). Always slow
down before entering a curve, especially when
turning on uneven ground or on a hillside.
Note: The wider the wheel spacing, the better the
stability of the sprayer and boom.
Suspension (optional)
Suspended axle systems are available featuring swing
arms, dual coil springs and gas shock absorbers.
Tank
The tanks, made of impact proof and chemical
resistant polyethylene, 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 drain valve is fitted for
efficient draining. Available tank size - 1100 gallon.
Pump
The HARDI®diaphragm pumps have low maintenance
requirements and guaranteed pump life. The bearings
and crankshaft are grease lubricated and are therefore
protected from spray solution if any diaphragm fails in
service. A drain hole is in the base of the crank case
to facilitate the draining of any foreign matter. The
diaphragm pumps are self priming and can be run
dry without damage. Centrifugal pumps and plumbing
systems are also available.
HARDI®SMART VALVE MANIFOLD system
All functions of the spray circuit are selected via
the centrally located simple, logical and functional
MANIFOLD valves, featuring color coding and clear
symbols for easy operation.
ECP operating unit
The ECP operating unit consists of: control box,
adjustable pressure agitation, pressure filter,
HARDIMATIC mechanical rate controller (within same
gear), 2-1/2” pressure gauge and individual boom feed
valve featuring constant pressure device for unchanged
application rate even if one or more boom sections are
shut off. The master on/off switch on the control box
operates by shutting off all boom sections regardless of
whether individual boom switches are on or off.
ECPC operating unit
The ECPC operating unit consists of: control box,
adjustable pressure agitation, 2-1/2” pressure gauge
and individual boom feed valves featuring constant
pressure device for unchanged application rate even
if one or more boom sections are shut off. The master
on/off switch on the control box operates by shutting
off all boom sections regardless of whether individual
boom switches are on or off.
Filters (standard and optional)
With the self-cleaning filter (ECP only), the impurities
that exist in the spray liquid will pass the filter and be
re-circulated back to the tank via the return flow. When
the tank is emptied, the impurities are then flushed out
through the drain. In-line filters and nozzle filters are
standard to ensure the sprayer will have minimal nozzle
blockages. Suction filter and filling filter are optional.
Booms
The HARDI®New NAVIGATOR boom options are as
follows:
New NAVIGATOR 1100
• 45’, 50’, 60’, 66’ Eagle™ SPB booms
• 80’, 88’, 90’, 100’ Eagle™ SPC booms
All of the booms are suspended in a strong, stable
parallelogram boom lift - Paralift™.
Booms feature trapeze/pendulum suspension and
an integrated spring suspension system with shock
absorber dampening.
Please refer to the EAGLE™ BOOM Operator’s Manual
for more information.

12. Before transporting the sprayer, ensure that the
boom is fully folded and fully locked into transport
position. Ensure all locking devices are fully en-
gaged, whether hydraulic or mechanical.
13. Slow moving tractors and spray equipment can cre-
ate 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 discon-
necting 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 machine while it’s 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 debris.
Handling chemical products safely
1. Direct exposure to hazardous chemicals can cause
serious injury. These chemicals can include lubri-
cants, 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 emer-
gency response techniques.
2. Protective clothing such as rubber gloves, goggles,
coveralls and respirator must be worn while han-
dling 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 decon-
taminate 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, trans-
ferring and applying chemicals after use. Follow
the instructions on the chemical label for the cor-
rect 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 ac-
cordance 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.

Wheel Spacing Adjustment
(Suspended and Non-suspended Axle)
Wheel spacing can be infinitely adjusted from 60” to
120” with suspended or non-suspended axle systems.
1Measure the correct wheel spacing (Center of right
hand tire to center of left hand tire). Each side must
be extended or retracted half the desired alteration.
2Attach sprayer to the tractor and engage tractor
parking brake.
3Place stop wedges in front of and behind the right
hand wheel ( Fig 5 ). Using suitable heavy duty
equipment, jack up the left hand wheel. Ensure
secure support for the sprayer body.
4To release axle wedge for the left hand wheel axle
and extend or retract the axle:
Turn Nut (C Fig 6 ) counterclockwise to allow
approx. 1” clearance. With an open-ended wrench,
turn Nut (D Fig 6 ) against anchor plate until hold on
axle is released. Shift axle to measured position.
5To tighten axle wedge and secure axle at required
width:
Turn Nut (D Fig 6 ) counterclockwise to allow
movement of stop wedge. Turn Nut (C Fig 6 )
clockwise against anchor plate to draw stop wedge
up against the axle and hold it in position. Tighten
to torque of 100 Ft/lb (135 Nm), then lock by re-
tightening Nut (D Fig 6 ).
6 If the wheels were reversed and exchanged,
remember to tighten the wheel nuts to the specified
torque - rim plate to hub 120 Ft./lb (180 Nm).
7Repeat the procedure on the right hand wheel.
8Check the distance from the center of the tire to
the center of the tank, to make sure the distance is
equal from left to right.
9Re-tighten the clamp bolts and wheel nuts to the
specified torque after 8 hours of work.
IMPORTANT! Always place a jack under axle and
lift the wheel to remove the load from the clamps
before tightening the clamp bolts.
WARNING! Use extreme caution with narrower
wheel spacing (close to 60”). Always slow
down before entering a curve, especially when
turning on uneven ground or on a hillside.
Note: The wider the wheel spacing, the better the
stability of the sprayer and boom.
Axle Clearance Adjustment
(Suspended and Non-suspended Axle)
The two axle inserts are equipped with offset spindles
allowing for a "low" or "high" clearance setting. To
change axle clearance:
1Follow steps 1-4 in "Wheel spacing adjustment"
section to release left
axle insert.
2Slide axle insert
completely out and

Use the optional HARDI®Electric 12 volt outlet box
(#817925 - Fig 11 ) if more than one power outlet is
needed.
Disconnecting sprayer
Always clean the sprayer inside and outside before
disconnecting and parking it. See Cleaning (pp. 28-29).
Before disconnecting the sprayer from the tractor, make
sure the support jack is properly fitted.
WARNING! To prevent the sprayer from tipping
over, do not disconnect the sprayer from the
tractor with the boom unfolded, unless the
boom is securely supported.
Place stop wedges in front of and behind wheels.
Remember to disconnect all hoses and cables from the
tractor.
WARNING! If the sprayer is parked unattended,
avoid unauthorized persons, children and
animals having access to the sprayer.
Sprayer Setup
Before operating sprayer
Although the sprayer has had a strong and protective
surface treatment applied to steel parts, bolts, etc. in
the factories, it is recommended to apply a thin layer of
anti-corrosion oil to all metal parts, hoses and tires.
There are many factors that affect the selection of
protective oils, such as temperature and humidity,
and exposure to UV, salt and chemicals. Your local
distributor of oil products will be able to advise on the
best specific formula for you local conditions. If this is
done before the sprayer is put into operation for the first
time, it will always be easy to clean the sprayer, avoid
chemicals discoloring the protective coating, and keep
the coatings shiny for many years.
This treatment should be carried out every time the
protective film is washed off.
Transport
Roadworthiness
Slow moving tractors and spray equipment can create
a hazard when on public roads. Make sure the S.M.V.
sign is in place and clearly visible from the rear of the
sprayer ( Fig 12 ).
NOTE! Max. driving speed is 15 mph (25 km/h).
Rear lights
Local regulations may require the use of flashing
warning lights. Connect plug for rear lights to the
tractor’s 7-pin socket, and check function of rear lights,
stop lights and direction indicators on both sides before
driving.

Adjusting boom transport position
If the boom wings do not rest accurately in the
transport brackets, the hydraulic fold cylinders can be
adjusted so the wings stop at the right position above
the transport brackets ( Fig 13 ).
Fig. 14
The cylinders can be adjusted as described below:
1. Lift the boom all the way to the top.
2. Fold the boom into transport position. With the fold
cylinder pressurized, determine if the boom wings
need to be adjusted inwards or outwards.
3. Relieve the pressure from the fold cylinder by
unfolding the boom a few inches.
If the boom rests too far in on the transport brackets,
loosen the nut (B Fig 14 ) and adjust collar (A Fig 14 )
in towards the cylinder housing.
If the boom rests too far out on the transport brackets,
the collar (A Fig 14 ) has to go out from the cylinder
housing.
4. Secure jam nut (B Fig 14 ).
5. Pressurize the cylinder to see if the boom is properly
adjusted. If not, repeat the above procedure until it is
correctly adjusted.
Sprayer Setup
Transport bracket settings
The transport brackets on the New Navigator for the
Eagle™ SPB and SPC booms are installed at the fac-
tory and have no adjustment.
The rear transport lock is adjustable, but is set at the
factory according to the boom installed on the sprayer.
This should not need adjustment unless a different
boom is installed on the sprayer.
WARNING! Always measure the actual total
height of your sprayer to be sure that there is
plenty of clearance at all times while trans-
porting the sprayer.
