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 fi nd many helpful hints as well as important safety and operation information.

Some of the features on your HARDI

®

1.0 INTRODUCTION

We congratulate you for choosing a HARDI

® plant protection product.

The reliability and effi ciency of this product depends on your care. The fi rst step is to carefully read and pay attention to this operator's manual.

It contains essential information for the effi cient use and long life of this quality product.

As this instruction book covers all N-series models, please pay attention to the sections dealing with your specifi c model.

This manual covers the HARDI

®

N-series 3-PT sprayers, available in

105, 155 or 210 gallon (400 L, 600 L or 800 L) capacities. They are equipped with a HARDI

®

603, 1203 or 1303 diaphragm pump (540

RPM P.T.O. drive), 3-PT frame and tank with electrical (EC) or manual

(ET or BK) controls. Available standard booms include:

controls are in the off or neutral position (including spray controls) and disengage the tractor power train.

3. Operate spray functions only when seated in the operator’s seat.

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.

HARDI ® N-SERIES 3-PT SPRAYER DIAPHRAGM OPERATOR'S MANUAL 9

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. Keep hands, feet & clothing away from moving parts.

8. Wear relatively tight and belted clothing to prevent from being caught on some part of the machine.

9. Slow down when turning.

10. Always keep children away from your sprayer and/or tractor unit.

11. 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.

12. 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.

13. 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.

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

5.4 Calibration (All models with standard booms)

WARNING: ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN

WATER ONLY! IN ADDITION, WEAR PROTECTIVE

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.

• 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):

HARDI ® N-SERIES 3-PT SPRAYER DIAPHRAGM OPERATOR'S MANUAL 43

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.

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)

44 HARDI ® N-SERIES 3-PT SPRAYER DIAPHRAGM 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:

GPM = GPA x MPH x W (in.)

5940

Formula:

GPM = 10 x 7 x 20 = .24 GPM

5940

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.

HARDI ® N-SERIES 3-PT SPRAYER DIAPHRAGM OPERATOR'S MANUAL 45

Calibration For Carriers Other Than Water

Use the following water rate conversion chart to determine the right conversion factor. When you've determined the new converted GPM or

GPA, you can follow the steps on either the pressure or ounce method of calibration.

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.

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

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. After determining your forward speed and choosing your application rate according to the recommendations on the chemical container, use the following formula to calculate the total nozzle capacity:

Formula:

Total GPM = W (ft.) x GPA x MPH

495

Note: W = Total measured sprayed width (ft.) at operating pressure.

3. To initially calculate which nozzle to use, let W = 30 ft., 40ft. or 50 ft. for HARDI ® Giant End Nozzles G-1000 Red, G-1200 White or G-

1600 Blue, respectively (Fig. 24 & Fig. 25).

Example: Total sprayed width: 40 ft. (G-1200 White nozzles)

Application rate: 20 GPA

Forward speed: 7 mph

11.3 GPM = 40 ft. x 20 GPA x 7 mph

495

HARDI ® N-SERIES 3-PT SPRAYER DIAPHRAGM OPERATOR'S MANUAL

Calibration (continued)

4. Divide the total nozzle capacity by 2 (the number of nozzles) to get the GPM needed per nozzle to match the speed, pressure and width used in the calculations (Example: 11.3 ÷ 2 = 5.65 GPM).

Capacity of single nozzle in GPM = Total GPM

Number of nozzles

5. For HARDI ® Giant End Nozzles, use the nozzle chart (Fig. 25) to fi nd the nozzle with the closest desired output and pressure. (The G-

1200 White nozzle at 50 PSI is the closest for this example at 5.948

GPM).

IMPORTANT: Al ways check actual sprayed width at operating

pressure once the correct nozzle has been chosen. Locate the sprayer in a suitable location and use clean water to check.

6. If the measured sprayed width at operating pressure differs from the value used in step 2, re-calculate the total nozzle capacity using the measured sprayed width. Divide by 2 to get the nozzle capacity in

GPM needed per nozzle (step 4). This will be the corrected nozzle capacity in GPM required from each nozzle for proper application rate.

7. Double-check the nozzle output with a measuring jug (using clean water at operating pressure). If the measured nozzle output matches the required calculated output, calibration is complete.

8. If necessary, use the following formulas to adjust either the spraying speed or operating pressure to achieve proper calibration.

New speed (MPH) = Desired output (GPM) x Previous speed (MPH)

Measured output (GPM)

New pressure (PSI) = Desired output (GPM) x Previous pressure (PSI)

Measured output (GPM)

Note: If the operating pressure is changed, the actual spraying width will need to be checked again. If spraying width differs, repeat steps 6-8.

Calibration For Carriers Other Than Water

Use the following water rate conversion chart to determine the right conversion factor. When you've determined the new converted GPM or

GPA, you can follow the steps in the formula method of calibration.

6.0 MAINTENANCE

IMPORTANT: Always clean the sprayer at the end of your workday

or before servicing is done to avoid unnecessary contact with chemicals.

In order to derive full benefi t from the sprayer for many years, the fol-

low ing few, but im por tant rules should be followed.

6.1 Cleaning The Sprayer

Guidelines

Read the whole label for the chem i cal used. Take note of any par tic u lar in struc tions regarding rec om mend ed protective clothing, de ac ti vat ing agents, etc. Read the de ter gent and de ac ti vat ing agent labels. If clean-

ing pro ce dures are given, follow them closely.

Be familiar with local leg is la tion regarding disposal of pes ti cides washings, man da to ry de con tam i na tion meth ods, etc. Contact the ap pro pri ate body (e.g. Dept. of Ag ri cul ture).

Cleaning starts with cal i bra tion, as a well cal i brat ed spray er will en sure a min i mal amount of re main ing spray liquid.

It is good practice to clean the spray er immediately after use, there by ren der ing the spray er safe and ready for the next ap pli ca tion. This also pro longs the life of the com po nents.

It is sometimes necessary to leave spray liquid in the tank for short pe ri ods - over night, or until the weather becomes suitable for spray ing again. Unauthorized per sons and animals must not have ac cess to the sprayer under these circumstances.

If the product applied is cor ro sive, it is recommended to coat all metal parts of the sprayer before and after use with a suit able rust in hib i tor.

Remember: Clean sprayers are safe spray ers.

Clean sprayers are ready for action.

Clean sprayers can not be dam aged by chemicals and

Cleaning

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

Note: It is ad vis able to in crease the forward speed (dou ble if possible) and reduce the pressure.

2. Select and use the ap pro pri ate protective clothing. Select detergent suitable for cleaning and suit able de ac ti vat ing agents if necessary.

3. Rinse and clean sprayer and tractor ex ter nal ly. Use de ter gent if necessary.

4. Remove all fi lters and clean them. Be careful not to damage the mesh. Replace fi lters when the sprayer is completely clean.

5. With the pump running, rinse the inside of the tank. Re mem ber the tank roof. Rinse and operate all com po nents 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 wa ter. Note that some chemicals require the tank to be com plete ly fi lled. Add appropriate detergent and/or deactivating agent, e.g. Washing soda or Triple ammonia.

Note: If a cleaning pro ce dure is given on the chemical label, follow it closely.

7. Start the pump and op er ate all controls en abling the liquid to come in contact with all the components. Leave the dis tri bu tion valves until last. Some detergents and de ac ti vat ing agents work best if left in the tank for a short period. Check the label.

8. Drain the tank and let the pump run dry. Rinse inside of tank, again letting the pump run dry.

9. Stop the pump. If the chemicals used have a tendency to block nozzles, re move and clean them now.

10. Replace all fi lters and noz zles and store the sprayer. If, from previous experiences, it is noted that the solvents in the chemicals are particularly ag gres sive, store the sprayer with the tank lid open.

Note: If the sprayer is cleaned with a high pres sure cleaner we recommend lu bri ca tion of the entire machine (Section 6.8).

6.2 Filters

IMPORTANT: Wear protective clothing when servicing & handling

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 fi lter will result in pump cavitation.

Suction fi lter

The main fi lter protecting spray er com po nents is the suc tion fi l ter at the top of the tank. Check it reg u lar ly. Make sure the O-ring on the fi lter housing is in good condition and lubricated*.

7.0 Off-Season Storage

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

1. Clean the sprayer completely - inside and outside - as described under "Cleaning The Spray er" (section 6.1). Make sure that all valves, hos es and auxiliary equipment have been cleaned with de ter gent and fl ushed with clean wa ter afterwards, so no chem i cal residues are left in the sprayer.

2. Replace any damaged seals and repair any leaks.

3. Empty the sprayer completely and let the pump work for a few minutes. Operate all valves and handles to drain as much water out of the spraying circuit as pos si ble. Let the pump run until air is coming out of all the nozzles.

4. Pour in a mixture of ethylene glycol base antifreeze and water at the ratio for the desired temperature protection (there will be a small amount of water left in the hoses, pump and bottom of tank). The volume of the mixture needs to be enough keep the tank sump full while the pump is running fl uid through the entire circuit.

5. En gage the pump and op er ate all valves and func tions of the plumbing system. Spray the spraygun (optional) into the tank until antifreeze sprays out to make sure the line is full of antifreeze.

Open the distribution valves so the an ti freeze is sprayed through the nozzles as well. The an ti freeze will also pre vent O-rings, seals, di a phragms 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 cat ing scheme regardless of intervals stated.

8. Re move the glycerine-fi lled pres sure gaug e and store in a vertical position in frost free con di tions.

9. Apply a thin layer of an ti cor ro sive oil (e.g. SHELL ENSIS FLU ID,

CASTROL RUSTILLO or sim i lar) on all metal parts. Avoid oil on rubber parts, hoses and tires.
