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: N105: 20' MB, 26' MB N155: 20' MB, 26' MB, 33' MB, 40' MB N210: 20' MB, 26' MB, 33' MB, 40' MB Other boom options include: No boom (spray gun only), pasture sprayer nozzles (30', 40', 50' spray width), VS8D 1-Row Berry Boom or VII 2-Row Berry Boom.

The heart of your sprayer is the diaphragm pump. The design is simple, resulting in 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 located in the base of the crank case to facilitate the draining of any foreign matter. The pump is self-priming and can be run dry without damage.

Agitation Adjustment

Ag i ta tion is nec es sary to keep the so lu tion in your tank prop er ly mixed. Con sult your chem i cal sup pli er for the rec om mend ed amount of ag i ta tion.

In gen er al, max i mum 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 fa cil i tate pump priming and avoid pressure ﬂ uc tu a tions.

Choice Of Correct Restrictor for S.C.F.

It is important to have a large ﬂ ow though the self clean ing ﬁ lter. This is achieved by choos ing the restrictor size in re la tion to the liquid con sump tion of the spray boom.

The hose (A) is un screwed from the self-clean ing ﬁ lter . Be careful not to lose the seal ball or spring when the restrictor is put in the hose and the hose is re ﬁ t ted. If the re quired working pres sure can not be ob tained, the restrictor is too large. 4 Restrictors are supplied. Use the green one (larg est or i ﬁ ce) ﬁ rst. Choose the next smaller restrictor. Start with a black one, then a white and ﬁ nal ly a red one.

5.4 Calibration (All models with standard booms)

WARNING: ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN 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. V ariations 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):

43HARDI® N-SERIES 3-PT SPRAYER DIAPHRAGM 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 f or 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

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 spra y from one nozzle for that amount of time. F or drop or band nozzles, catch the spra y 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). T rav el the distance at the speed you plan on spraying

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

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.

5.5 Calibration (Pasture sprayer model only)

WARNING: ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN

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 recom-

mended 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.

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.

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 G1600 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

48 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 = 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 G1200 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.

Total GPM

New speed (MPH) = Measured output (GPM)

New 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.

Desired output (GPM) x Previous speed (MPH)

Desired output (GPM) x Previous pressure (PSI)

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 their solvents.

51HARDI® N-SERIES 3-PT SPRAYER DIAPHRAGM OPERATOR'S MANUAL

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 previ-

ous 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 recom-

mend lu bri ca tion of the entire machine (Section 6.8).

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

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*.

Pressure ﬁ lter (BK-3 Control Unit only)

The BK-3 Control unit is equipped with a built-in pressure ﬁ lter. Unscrew the base to check and clean the ﬁ lter. 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.
