Dear Owner,

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.

Navigator HC 550M Centrifugal w/ Eagle™ Boom

5HARDI® NAVIGATOR 550M, 800M, 1000M CENTRIFUGAL OPERATOR'S MANUAL

1.0 INTRODUCTION

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.

The Navigator 800M is no longer available

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 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.

4.6 Manifold Operating In structions

The green pres sure valves and the black suction valves have 4 po sitions. Two positions are for op tions. The oth er two are marked “O” in dicating the valve is closed. The ar row on the han dle in dicates which position is se lected.

Green Pressure Valves

To select the optional equip ment, the handle is turned so the ar row and there by liquid is di rected to the op tional extra instead of the ESC operating unit. When spray ing is to re sume, turn the handle so the ESC operating unit is selected. The other handles are turned to “O”. If all the green pressure valves are closed, the centrifugal pump will be dead headed.

WARNING

Black Suction Valves

Turn the handle so the arrow points to wards the selected op tional equipment (e.g. Flush Tank). To re sume suction from the main tank, the arrow must point to wards the main tank. Re maining valve must be closed.

Note: The quick ﬁ ll valve (if ﬁ tted) is not connected to the manifold

green symbol.

5. Hold pressure regulating switch (C) (Fig. 16) to (-) until handle (2) (Fig. 15) stops rotating, this will be the "minimum pressure" setting.

6. Hold pressure regulating switch (C) (Fig. 16) to (+) until desired

pressure is shown on the pressure gauge (4) (Fig. 15).

24 HARDI® NAVIGATOR 550M, 800M, 1000M CENTRIFUGAL OPERATOR'S MANUAL

4.9 Adjustment of Constant Pressure

Note: Adjust the constant boom section pressure one section at a time

as follows: (Start with the valve turned closed before adjusting).

1. Shut-off the ﬁ rst boom section valve switch (B) (Fig. 16).

2. Turn the adjusting screw (1) (Fig. 15) until the control unit pressure gauge (4) (Fig. 15) again shows the same pressure as set in step 6 (Section 4.8). (Turn the screw clockwise for higher pressure, coun-

terclockwise for lower pressure).

3. Turn the boom section valve switch (B) (Fig. 16) back on.

4. Repeat steps 1 through 3 for the remaining boom section valves.

Note: Hereafter adjustment of the constant boom pressure will only be needed if you change to nozzles with other capacities, but not required if only changing pressure or application rate using the same nozzles.

5. Operating the control unit while driving: In order to shut off the entire boom, turn ON/OFF switch to "Off" position (A) (Fig. 16). This returns all the pump outputs to the tank through the return system. The diaphragm antidrip valves ensures instantaneous closing of all noz zles.

In order to shut off one or more sections of the boom, switch one or more unneeded boom section valves (B) (Fig. 16) to "Off" position. The constant pressure device ensures that the pressure does not increase in the sections which are still operating.

In case of electrical failure, it is still possible to manually override all functions of the operating unit. To operate manually, disconnect the multiplug from the ESC control box ﬁ rst and operate the handles by hand. It is possible to change pressure, turn boom sections on or off, or shut off the complete control unit manually.

IMPORTANT:

When the sprayer is stored, the ESC control box and the multiplug must be protected against moisture and dirt. A plastic bag may be used to protect the multiplug. Store the control box in a clean dry place.

4.10 Agitation Adjustment (Agitation nozzles only)

Agitation is necessary to keep the solution in your tank properly mixed. Consult your chemical supplier for the recommended amount of agitation.

In general, maximum agitation is required but some products tend to foam easily. To reduce foaming in some instances anti-foaming agents may be added to the tank (Refer to chemical label). When running low liquid levels in the tank, agitation may be reduced to facilitate pump priming and avoid pressure ﬂ uctuations. Make sure that you have adjusted the agitation properly before sprayer calibration.

Turning the agitation valve (A) (Fig. 17) clockwise will reduce the agitation ﬂ ow. Turning the valve counter clockwise will increase the agitation ﬂ ow.

4.14 Nozzle Selection

Correct selection of nozzle and calibration of the sprayer are critical to achieve accurate and cost effective use of farm crop protection products.

Your HARDI® sprayer has been supplied with 110° ﬂ at spray Red ISO Color Tips™ that will apply approximately 20 U.S. GPA at 30 PSI and 5 MPH. The 110° ﬂ at spray nozzle was chosen rather than the 80 degree nozzle for two reasons: 1- It may be used at a lower minimum height which reduces the risk of wind drift; 2- it's greater overlap permits better uniformity of spray distribution, particularly if boom height varies on rough ground. Normal boom height setting with 110° nozzles is 18" to 20" above the crop or weeds, whichever is taller. Should you wish a different application rate or different type of nozzle, HARDI® manufactures a nozzle for virtually every need.

IMPORTANT:

Always consult your chemical supplier for rec ommended chemical rate and water application rate. Always wear protective gloves when handling nozzles.

The following tables show what types of spray nozzles are suitable for different applications. It is important to use the correct nozzle.

4.15 Calibration

WARNING:

WATER ONLY! IN ADDITION, WEAR PROTECTIVE CLOTHING WHEN CALIBRATING YOUR SPRAYER!

Why must you calibrate a sprayer?

A nozzle selection chart will tell you what application rate you should expect. Variations due to nozzle wear, errors in pressure adjustment, and tractor speedometer can result in a possible error in application rate.

How do you calibrate a sprayer?

Calibration kits are available from HARDI®, #818493 for US gallons & #818492 for metric calibration. Following are some tips to remember when using the calibration kit method:

• When determining the length of time required to drive the recommended distance, drive in actual ﬁ eld conditions with a half-full tank.

• Repeat the test several times, each time avoiding the tracks from the previous test. Take the average of the times recorded.

• Calibration of the sprayer should be completed at the beginning of the season and repeated after every 2 to 3 full days of spraying, and every time you change volume rate or use new nozzles.

ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN

• Before you calibrate, check the ﬂ ow of each nozzle. If it puts out more than 10% of its original volume, replace it.

Select your calibration method: Ounce method or Formula method. Then follow the steps described in the corresponding section(s):

38 HARDI® NAVIGATOR 550M, 800M, 1000M CENTRIFUGAL OPERATOR'S MANUAL

Ounce Method

1. Determine how long it takes to cover the test strip. Use the following chart to determine the length of your test strip. Row width for broadcast application is equal to your nozzle spacing. For your drop nozzle or band application, use row spacing.

Row width or nozzle spacing (in.) Distance (ft.)

40 102 38 107 36 113 34 120 32 127 30 136 28 146 26 157 24 170 22 185 20 204 18 227 16 255

14 291

2. Measure the amount of time it takes you to travel the test strip when

throttle is set at spraying speed.

3. In a container (with oz. measurements), catch the spray from one nozzle

for that amount of time. For drop or band nozzles, catch the spray from all nozzles for the row.

4. Read the ounces in the container. That is the actual U.S. GPA applied.

(ounces = GPA)

39HARDI® NAVIGATOR 550M, 800M, 1000M CENTRIFUGAL OPERATOR'S MANUAL

Formula Method

1. Check your spraying speed. Measure a test strip of at least 200 feet (300 feet is ideal). Travel the distance at the speed you plan on spraying

and record the time it takes to travel the distance. Read from the chart or use the formula to ﬁ nd your exact travel speed.

2. Calculate the required nozzle output. Use either the nozzle wheel (if nozzle spacing is 20 inches), or this formula:

Formula: Formula:

GPA x MPH x W (in.)

GPM =

5940 5940

GPM =

10 x 7 x 20

Note: W= • Nozzle spacing (in inches) for broadcast application.

• Row spacing (in inches) divided by number of nozzles per row for drop nozzle application.

• Sprayed band width or swath width (in inches) for band application divided by number of nozzles per band.

• Note that on the nozzle wheel, W = 20 inches.

3. Set correct pressure. Read the required pressure from the nozzle table in the nozzle catalogue or nozzle wheel. With clean water in the tank

and line, turn on the sprayer and set the target pressure. Collect the spray from one nozzle for one minute in a container. Adjust pressure until you collect the precise GPM called for.

5.0 MAINTENANCE

IMPORTANT:

before servicing is done to avoid unnecessary contact with

chem icals.

In order to derive full beneﬁ t from the sprayer for many years, the following service and maintenance program should be followed.

5.1 Cleaning The Sprayer

Guidelines

Read the whole chemical label. Take note of any particular instructions regarding recommended protective clothing, deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures are given, follow them closely.

Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods, etc. Contact the appropriate department, e.g. Dept. of Agriculture.

Pesticide washings can usually be sprayed out on a soakaway. This is an area of ground that is not used for cropping. You must avoid seepage or runoff of residue into streams, water courses, ditches, wells, springs, etc. The washings from the cleaning area must not enter sewers. Drainage must lead to an approved soakaway.

Always clean the boom at the end of your workday

Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining spray liquid. It is good practice to clean the sprayer immediately after use, thereby rendering the sprayer safe and ready for the next pesticide application. This also prolongs the life of the components.

It is sometimes necessary to leave spray liquid in the tank for shor t periods, e.g. overnight, or until the weather becomes suitable for spraying again. Unauthorized persons and animals must not have access to the sprayer under these circumstances.

If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after use with a suitable rust inhibitor.

Remember: Clean sprayers are safe sprayers. Clean sprayers are ready for action. Clean sprayers can not be damaged by pesticides and their

solvents.

42 HARDI® NAVIGATOR 550M, 800M, 1000M CENTRIFUGAL OPERATOR'S MANUAL

Cleaning the tank

1. Dilute remaining spray liquid in the tank with at least 10 parts of water and spray the liquid out in the ﬁ eld you have just sprayed.

Note: It is advisable to increase the forward speed (double if

possible) and reduce the pressure. For ISO F110 nozzles, pressure may be reduced to 22psi (1.5 bar).

2. Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivating agents if necessary.

3. Rinse and clean sprayer and tractor externally. Use detergent if

necessary.

4. Remove and clean tank ﬁ lters and suction ﬁ lters. Be careful not to damage the mesh. Replace suction ﬁ lter lid. Replace ﬁ lters when the sprayer is completely clean.

5. With the pump running, rinse the inside of the tank. Remember the tank roof. Rinse and operate all components and any equipment that has been in contact with the chemical.

6. After spraying the liquid out again in the ﬁ eld, stop the pump and ﬁ ll at least 1/5 of the tank with clean water. Note that some chemicals require the tank to be completely ﬁ lled. Add appropriate detergent and/or deactivating agent, eg. Washing soda or Triple ammonia.

Note: If a cleaning procedure is given on the chemical label, follow it

closely.

7. Start the pump and operate all controls enabling the liquid to come in contact with all the components. Leave the distribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short period. Check the label.

8. Drain the tank and let pump run dry, only for a few seconds. Rinse inside of tank, again letting the pump run dry again only for a few seconds.

Note: Do not run pump dry for longer than 3 seconds. Otherwise

severe damage to the pump will occur.

9. Stop the pump. If the chemicals used have a tendency to block nozzles and ﬁ lters, remove and clean them now.

10.Replace all the ﬁ lters and nozzles and store the sprayer. If, from

previous experiences, it is noted that the solvents in the chemicals are particularly aggressive, store the sprayer with the tank lid open.

Note: If the sprayer is cleaned with a high pressure cleaner we

recommend lubrication of the entire machine.

5.2 Filters

IMPORTANT:

components that have been in contact with spray liquid.

Clean ﬁ lters ensure :

• Sprayer components such as valves, diaphr agms and operat ing unit are not hindered or damaged during operation.

• Nozzle blockages do not occur while spray ing.

• Long life of pump. A blocked suction filter will result in pump cavit ation.

5.3 Recommended Tire Pressure

The tires should not run under-inﬂ ated. This only promotes instability and rapid wear.

NAVIGATOR 550M

Tire size: Maximum pressure:

11L x 15" 36 psi (2.5 bar)

11.2 x 38" 24 psi (1.6 bar)

12.4 x 24" 24 psi (1.6 bar)

NAVIGATOR 800M/1000M

Tire size: Maximum pressure:

12.5L x 15" 36 psi (2.5 bar) - (TA no longer available)

13.6 x 38" 29 psi (2.0 bar)

12.4 x 42“ 10 ply 36 psi (2.5 bar)

The pressure is speciﬁ ed for a fully loaded trailer. When traveling on hard road surfaces with a maximum load, do not exceed 15 mph. Remember it is easier to let off a little pressure for a speciﬁ c use than to re-inﬂ ate a tire in mid-ﬁ eld.

5.4 Wheel Nuts And Bearings Adjustment

WARNING:

Check wheel bolt tension after the ﬁ rst 8 working hours, hereafter every 50 hours. Torque wheel nuts to 85 ft. lbs. maximum. Check bearing for slack after the ﬁ rst 8 hours of operation and again after 50 hours of operation. Thereafter every 100 hours. (Fig. 21)

BLOCK WHEELS ON TRAILER TO PREVENT ROLLING.

If necessary, adjust as follows:

1. Jack sprayer up. It is best to remove the wheel. (Make sure to adequately support the sprayer and completely drain tank.)

2. Remove hub cap and cotter pin.

3. Axle nut is tightened until slight rotation resistance of hub is noted.

4. Now loosen axle nut until ﬁ rst split pin hole is visible.

5. Insert cotter pin, fold and replace hub cap.

After 1000 hours or once a year, the axle bear ings should be repacked with new

grease.

5.6 Nozzle Tubes And Fittings

Poor seals are usually caused by;

• Missing O-rings or gaskets

• Damaged or incorrectly seated O-rings

• Dry or deformed O-rings or gaskets

• Foreign materials

Therefore, in case of leaks; DO NOT overtighten (Fig. 23). Disassemble, check condition and position of O-ring or gasket, clean, lubricate and reassemble.

For radial type seals (O-ring)(Fig.23) hand tighten only, do not use pli- ers.

The O-rings need to be lubricated ALL THE WAY AROUND before ﬁ tting on to the nozzle tube.

Fig. 23

HARDI® recommends using a vegetable based oil to prolong the life of the O-ring.

5.10 Emergency Operation Of ESC Controls

In case of power failure, it is possible to operate all functions of the operating unit manually. First disconnect the multiplug from the control box. Now manually turn the emergency control knobs.

The problem may be due to a blown fuse. The fuses are placed in the control box and are marked according to functions.

Fuse type:

0.5 Amp (HARDI®#261125)

1.25 Amp (HARDI®#261589)

6.3 Amp (HARDI®#261090)

Fig. 27

5.11 Level Indicator

The level indicator should be checked regularly. When the tank is empty, the ﬂ oater should rest on the stop pin on the rod and the O-ring at the indicator should be positioned at the top position line (A) (Fig. 28).

If any deviation is found, pull out the plug (B) (Fig. 28), loosen the screws (C) (Fig.

28) and adjust the length of the cord.

Note: The level indicator is not meant to be an accurate indication of the speciﬁ c volume of your tank. Variations due to the adjustment of the indicator, po sitioning of the sprayer and the production of the tank itself, are all factors leading to some inaccuracy. For precise mea surement rely only on weight of the liquid or precise ﬂ owmeters when ﬁ lling the tank.

6.0 OFF-SEASON STORAGE

When the spraying season is over, you should de vote some extra time to the Spray er. If chem ical res idues are left over in the spray er for long periods, it can reduce the life of the individual com ponents. To pre serve the sprayer and pro tect the com ponents, carry out the following offseason stor age pro gram:

1. Clean the sprayer completely - inside and outside - as described under "Cleaning The Spray er" (Section 5.1). Make sure that all valves, hos es and auxiliary equipment have been cleaned with detergent and ﬂ ushed with clean wa ter afterwards, so no chem ical residues are left in the sprayer.

2. Re place any damaged seals and repair any Ieaks.

3. Empty the sprayer com pletely and let the pump run dry, only for a few seconds. Operate all valves and handles to drain as much water out of the spraying circuit as pos sible. Let the pump run until air is coming out of all nozzles. Re member to drain the ﬂ ush tank also.

Note: Do not run pump dry for longer than 3 seconds. Otherwise

severe damage to the pump will occur.

4. Pour appr. 13 gal. (50 liters) antifreeze mixture con sisting of 1/3

automotive antifreeze and 2/3 water into the tank.

5. En gage the pump and op er ate all valves and func tions on the MANIFOLD system, ESC unit, CHEM FILLER etc. al low ing the antifreeze mix ture to be distributed around the en tire circuit. Open the ESC main on/off switch and distribution valves so the an tifreeze is sprayed through the nozzles as well. The an tifreeze will also pre vent O-rings, seals, di aphragms etc. from dry ing out.

6. When the sprayer is dry, re move rust from any scratch es or damages in the paint and touch up the paint.

7. Lubricate all lubricating points according to the lu bri cating scheme regardless of intervals stated.

8. Re move the glycerine-ﬁ lled pres sure gaug es and store them in a vertical position in frost free con ditions.

9. Apply a thin layer of an ticorrosive oil (e.g. SHELL ENSIS FLU ID, CASTROL RUSTILLO or sim ilar) on all metal parts. Avoid oil on rubber parts, hoses and tires.

10. Fold the boom in transport po sition and re lieve pres sure from all

hydraulic func tions.
