HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL

Dear Owner,

Thank you for purchasing a HARDI® product and welcome to the everincreasing family of HARDI® equipment owners.

Our sprayers and accessories are rapidly becoming a familiar sight on North American farms and estates. 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 find many helpful hints as well as important safety and operation information.

Some of the features on your HARDI® Estate Sprayer were suggested by growers. There is no substitute for “on farm” experience and we invite your comments and suggestions.

Please address your correspondence to the Service Manager at one of these branches:

1.0 INTRODUCTION

We congratulate you for choosing a HARDI® plant protection product. The reliability and efficiency of this product depends on your care. The first step is to carefully read and pay attention to this operator’s manual. It contains essential information for the efficient use and long life of this quality product.

This manual covers the HARDI & Stratton or Honda gas engines directly coupled to HARDI® 500 or 600 diaphragm pumps. These sprayers include the ES 50, ES 80, SM 50 and SM 80 models.

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.

The ES 50 and ES 80 sprayers are equipped with the ET manual control which features: on/off control for boom and handgun, pressure adjustment, pump bypass agitation, remote pressure safety valve and a 2-1/2” pressure gauge.

Estate Sprayers equipped with Briggs

The SM 50 and SM 80 sprayers are equipped with the M600 Brass manual control which features: on/off control for handgun/(optional boom), pressure adjustment, pump bypass agitation, integral pressure safety valve and a 2-1/2” pressure gauge.

The tanks, made of impact proof and chemical resistant polyethylene, have a purposeful design with rounded contours which allows for efficient cleaning and draining. They are designed with a large deep sump so that they can be completely emptied even when the sprayer is used on slopes. A drain plug is provided in the sump to assist cleaning of the tank. The tanks are equipped with a top suction filter which can be inspected and cleaned without emptying the tank.

Also covered in this manual are the 6’ FD and 14’ HD booms which feature fore and aft breakaways. The 6’ FD boom folds vertically and the 14’ HD boom folds horizontally forward. Both booms feature ISO flat fan nozzles with 20” spacing.

HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL

The frame and boom of your estate sprayer are finished with a powder coat paint which provides maximum protection from chemicals and rust.

The model 60L spraygun features an adjustable spray nozzle for varying the spray width. The standard spraygun features 25’ of 1/2” hose on the hose wrap (optional 40’).

Since this book covers options available for several different Estate Sprayers, please pay attention to the sections dealing specifically with your model.

6.0 CALIBRATION

WARNING:

WATER ONLY! WEAR PROTECTIVE CLOTHING SUCH AS RUBBER GLOVES, GOGGLES AND COVERALLS.

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 large error in application rate.

How do you calibrate a sprayer?

Calibration kits are available from HARDI®, #818493 for U.S. Gallons and #818492 for metric calibration. For accurate calibration, the sprayer is driven a specific distance at spraying speed and the length of time is recorded. The operator then measures the amount of water sprayed from one nozzle at spraying pressure for the same length of time noted. The amount of water sprayed provides a direct reading of application rate. Slight adjustments are then made by varying the pressure.

Here are some tips to remember when using the calibration kit method:

1. Calibrate with clean water only.

2. Follow the instructions in the calibration kit carefully.

3. Before calibration, check the flow of each nozzle. If it puts out more than 10% of its original volume, replace it.

4. When determining the length of time required to drive a recommended distance, drive in actual field or lawn conditions with a half full sprayer. Repeat the test several times, then take the average of the times recorded.

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

ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN

NOTE: A Calibration & Nozzles Manual (HARDI® ref. no. 67000103) is available from your HARDI® dealer which contains more detailed information for calibration and nozzle selection.

HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL

6.1 Calibration (Ounce Method)

If you do not wish to use the calibration kit method, the following method may be used. All you need is a tape measure, stop watch and a container that accurately measures U.S. fluid ounces.

1. Fill the sprayer tank approximately half full with clean water.

2. Set up two stakes, 204 ft. apart in actual spraying conditions.

3. While driving at spraying speed, note the length of time required to drive 204 ft. Repeat several times and take the average of the times recorded.

4. With the sprayer operating at intended spraying pressure, collect the output from one nozzle for the length of time determined in step 3. The number of U.S. fluid ounces will exactly measure the application rate.

e.g. 15 U.S. fluid ounces = 15 U.S. gallons per acre

NOTE: This method only works if the nozzle spacing is 20”.

For conversion to Imperial gallons per acre, multiply U.S. GPA x .833 For conversion to liters per hectare, multiply U.S. GPA x 9.34 For conversion to liters per acre, multiply U.S. GPA x 3.78

7.0 MAINTENANCE

WARNING:

PEOPLE AND ANIMALS. NEVER LEAVE A SPRAYER CONTAINING CHEMICALS WHERE IT COULD BE ACCESSED BY UNAUTHORIZED PEOPLE OR ANIMALS.

IMPORTANT:

before servicing to avoid unnecessary contact with chemicals.

In order to derive full benefit from the sprayer for many years, the following few, but important rules should be followed.

7.1 Cleaning The Sprayer

Read the entire label of the chemical used. 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.

UNCLEAN SPRAYERS CAN BE HAZARDOUS TO

Always clean the boom at the end of your workday or

HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL

7.1 Cleaning The Sprayer (cont.)

Be familiar with local legislation regarding disposal of agricultural chemicals, mandatory decontamination methods, etc. Contact the appropriate office, e.g. Department of Agriculture.

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

It is sometimes necessary to leave the spray liquid in the tank for short periods of time (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.

Cleaning

1. Dilute the remaining spray liquid in the tank with at least 10 parts water and spray the liquid out into the field or lawn you have just sprayed.

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

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

4. Remove all filters and clean them. Be careful not to damage the mesh. Replace filters 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 field or lawn, stop the pump and fill at least 1/5 of the tank with clean water. Note that some chemicals require the tank to be completely filled. Add appropriate detergent and/or deactivating agent, e.g. 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.

HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL

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, remove and clean them now.

10. Replace all filters 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.

7.2 Lubrication

Every 40 hours of operation, new grease should be applied to the pump and boom. Use a high quality multi-purpose lithium based grease. When greasing the pump, use only 2 to 3 pumps from a grease gun. For easier application of grease to the boom, place the wing in the breakaway position. Also oil the M600 control as shown every 40 hours of operation.

• Damaged or incorrectly seated O-rings

• Dry or deformed O-rings or gaskets

• Foreign materials

Therefore, in case of leaks; DO NOT overtighten any fittings (Fig 5). Disassemble, check the condition and position of the O-ring or gasket, clean, lubricate and then reassemble. For radial seals (O-ring) (Fig 5), only hand tighten the fittings. Do not use pliers or wrenches.

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

Fig. 5

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

7.5 Pump Maintenance

Changing the valves

Remove valve cover 1 (Fig 6). Before changing the valves 2 (Fig 6), note the orientation of the valves so that they may be replaced correctly. It is recommended to use new seals 3 (Fig 6) when changing or checking the valves.

HARDI® GAS ENGINE ESTATE SPRAYER OPERATOR’S MANUAL

Changing the diaphragms

Remove the diaphragm cover 4 (Fig 6) after removing the valve cover. The diaphragm 5 (Fig 6) may then be changed. If fluids have reached the crankcase, re-grease the pump thoroughly. Also make sure the drain hole at the bottom of the pump is not blocked. Use the following torque chart when re-tightening bolts:

Diaphragm Bolt - 18.5 Ft/Lbs Diaphragm Cover Bolts - 37 Ft/Lbs Valve Cover Bolts (500) - 22 Ft/Lbs Valve Cover Bolts (600) - 34 Ft/Lbs

7.6 Boom Maintenance

The 6’ FD boom breakaway should be adjusted tightly enough so that the boom stays securely in the upright (folded) position during transport, yet loosely enough that the boom easily swings back if an obstacle is hit. Adjustment is made by tightening or loosening the spring tension bolt (Fig 7).

8.0 STORAGE

When the spraying season is over, you should devote some extra time to the sprayer. If chemical residues are left over in the sprayer for long periods, it can reduce the life of the individual components. To preserve the sprayer and protect the components, carry out the following off-season storage program:

1. Clean the sprayer completely - inside and outside - as described in Section 7.1 “Cleaning The Sprayer“. Make sure that all valves, hoses and auxiliary equipment have been cleaned with detergent and flushed with clean water afterwards, so no chemical 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 possible. Let the pump run until air is coming out of all nozzles.

4. Fill the tank with 3 - 5 gallons of an ethylene glycol base anti-freeze mixture at the ratio for the desired temperature protection. Run the pump and circulate the anti-freeze through the distribution valves and boom lines. Spray the handgun into the tank until anti-freeze sprays out to make sure the line is full of anti-freeze.

NOTE: Never use diesel fuel in a sprayer.

5. When the sprayer is dry, remove rust from any scratches in the paint and touch up the paint.

6. Lubricate the boom (Section 7.2).

7. Remove the glycerine-filled pressure gauge and store in a vertical position in a frost-free environment.

8. To protect against dust, the sprayer can be covered by a tarpaulin. Ensure ventilation to prevent condensation.

8.1 Preparation After Storage

After a storage period, the sprayer should be prepared for the next season in the following way:

1. Remove the cover (If fitted).

2. Fit the pressure gauge again. Seal with Teflon tape.

3. Connect the sprayer to the tow vehicle (Section 3.0).

4. Empty the remaining antifreeze into an approved container.

5. Rinse the entire liquid circuit on the sprayer with clean water. Don’t forget to flush the boom and handgun lines also.

6. Fill with clean water and check all functions (Section 4.0).
