Description

Frame

Strong and compact frame with optional drawbars and wheel sizes. The frame has a strong chemical and weather resistant powder coat. Screws, nuts, etc. have been electrochemically treated to be resistant to corrosion.

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 valve drain is fitted for efficient draining.

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.

MANIFOLD SYSTEM

All functions of the spray circuits are operated via the centrally situated MANIFOLD valves with color coded plates and pictorial symbols for easy operation.

Operating unit

The ECP - Electrical Control Plus is divided into two sections. The pressure regulation valve is located at the front of the sprayer. The boom section control valves with pressure equalization are mounted at the rear of the sprayer. The on/off switch is linked to the boom section valves, which results in a very quick response to on/off operation. The built-in HARDIMATIC mechanical rate controller ensures a constant volume per acre of the liquid (gpa) at varying forward speed within the same gear when the number of P.T.O. revolutions are between 300-600 r.p.m. (540 r.p.m pump) or 650-1100 r.p.m. (1000 r.p.m. pump).

Paralift™

The Paralift™ boom lift system consists of parallel lift arms that hydraulically lift and lower the boom assembly, ensuring that the boom remains parallel to the ground. A locking cylinder and arms are fitted to ensure that the paralift cylinders are relieved of any hydraulic pressure when the boom is in the transport position.

Booms

The EAGLE™ SPB boom is available in 45’, 50’, 60’, and 66’ working width. The EAGLE™ SPC boom is available in 80’, 88’, 90’ and 100’ working width. The FORCE™ FTZ boom is available in 80’, 88’, 90’, 100’ and 120’ working widths. Outer sections incorporate spring loaded breakaways.

Boom hydraulics

The SPB, SPC and FTZ booms are equipped with I.A.H. (Indirect Acting Hydraulics). Optional D.H. (Direct Acting Hydraulics) is available.

The boom is operated via the tractor hydraulics. It features hydraulic lift cylinders for boom height adjustment, boom wing fold and tilt cylinders that give the ability to obtain individual boom wing tilt as well as individual boom wing fold.

The hydraulics are controlled via a joystick or via a hydraulic control box.

Identification plates

An identification plate fitted on the frame indicates model and serial number. Frame, boom center frame, and inner/outer sections also have identification plates indicating boom type and part number of spare parts. If ordering spare parts, inform your dealer of these, so the right model and version are described.

Filters

With the self-cleaning filter, the impurities that exist in the spray liquid will bypass the filter and be recirculated back to the tank via the return flow. Suction filter and inline pressure filters are standard with all booms.

Description

Sprayer use

The HARDI® COMMANDER Plus sprayer is for the application of crop protection chemicals and liquid fertilizers.

If no local law demands that the operator must be certified to use the spray equipment, it is strongly recommended to be trained in correct plant protection and in safe handling of plant protection chemicals to avoid unnecessary risk for persons and the environment when doing the spray job.

Unloading the sprayer from the truck

When unloading the sprayer, a crane or a fork lift is needed. When loading with a crane, please observe the lifting points as shown on the illustration and make sure that the straps or belts used for lifting are suitable for the application.

Before putting the sprayer into operation

Although the sprayer has been applied with a strong and protective surface treatment on steel parts, bolts etc. in the factories, it is recommended to apply a film of anticorrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) on all metal parts in order to avoid chemicals and fertilizers discoloring the enamel. Avoid oil on rubber parts, hoses and tires.

If this is done before the sprayer is put into operation for the first time, it will always be easy to clean the sprayer and keep the enamel shiny for many years.

This treatment should be carried out every time the protection film is washed off.

Driving Technique

Steering drawbar (optional)

A trailer with an articulating drawbar behaves differently than a normal trailer.

In tracking position the vehicle’s center of gravity is displaced further from the vehicle’s center line than that of a normal trailer.

Compared to a conventional trailer, a trailer equipped with a steering drawbar has decreased stability when turning, especially when turning on hillsides.

To avoid instability or overbalancing, pay attention to these guidelines:

1. Avoid sudden, tight turns

2. Slow down before entering a curve or turning, and drive with a constant, low speed during the turn.

3. Never slow down too fast, never brake heavily and never stop suddenly in a curve, or when turning on a hillside, when the sprayer is articulated.

4. Be careful when turning on uneven ground

5. Set the wheel width as wide as possible

6. The proper function of the hydraulic damping is essential to obtain good stability

7. Keep stabilizer chains on the tractor’s liftarms tight

8. For safety reasons, the following limitations are set for sprayers equipped with steering drawbar (with unfolded booms):

MAX. 8º

MIN. 72"

Speed while turning, max. 2.5 m.p.h. (4 km/h)

Ground inclination while turning, max. 8°

Wheel width, min. 72” with steering drawbar

Make sure the following safety decals are in place and that you understand and follow each one:

Operating the liquid system

MANIFOLD SYSTEM

The “Manifold System” is located at the left side of the sprayer, permitting operation of most of the (fitted) accessories from one position. The modular design of the Manifold system allows the easy addition of many accessories to the plumbing system of the sprayer. The system can be expanded to a maximum of 4 valves on the pressure side. The suction side can be expanded to a maximum of 2 valves. The system is also fitted with an agitation valve, enabling the tank agitation to be turned on or off. It also features a self-cleaning filter return hose on/off valve, which allows the return to be turned on or off.

Use of MANIFOLD valve system

The Manifold valve faces are colored discs for easy identification:

Green disc = Pressure valve Black disc = Suction valve Yellow disc = Self-cleaning filter

Adjustment of constant pressure

Note: Adjust the constant distribution boom pressure

one section at a time as follows: (Start with the valve turned closed before adjusting).

1. Shut-off the first boom distribution valve switch B.

2. Turn the adjusting screw(s) until the control pressure gauge again shows the same pressure as in step 6 (to left) (Turn the screw clockwise for higher pressure, counterclockwise for lower pressure).

3. Turn the first boom distribution valve switch B back on.

4. Repeat steps 1-3 for the remaining boom distribution 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.

Operating the control unit while spraying

In order to shut off the entire boom, flip on-off switch A to the off (red) symbol (up position). This returns all the pump outputs to the main tank through the return system. The diaphragm anti-drip valves ensure instantaneous closing of all nozzles.

A. Operating switch for main on/off

B. Operating switch for distribution valves C. Pressure control switch (to lower or raise)

Before spraying, adjust the ECP operating unit using clean water (without chemicals).

1. Choose the correct nozzle (pp. 33-34). Make sure that all nozzles are the same type and capacity.

2. Put the tractor in neutral and adjust the P.T.O. r.p.m. until the number of revolutions of the pump corresponds to the intended traveling speed. Remember the number of revolutions on the P.T.O. must be kept between 300-600 r.p.m. (540 r.p.m. pump) or 6501100 (1000 r.p.m. pump) to ensure correct operation of the HARDI-MATIC system.

3. On-off switch A is “ON” against green symbol (down position).

4. All distribution valve switches B are also “ON” against green symbol (down position).

5. Hold pressure regulating switch C down (-) until handle stops rotating. This will be the “minimum pressure” setting.

6. Hold pressure regulating switch C up (+) until desired pressure is shown on the boom pressure gauge.

In order to shut off one or more sections of the boom, switch the relevant distribution valve B to off position. The constant pressure system ensures that the pressure does not increase in the sections which are still open.

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 ECP control box first and operate the handles by hand. It is possible to change pressure and turn boom sections on or off.

Note: Since the on-off switch normally operates by shutting off all the boom distribution valves, you will need to manually shut off all the distribution valves to shut off the complete control unit manually.

IMPORTANT! When the sprayer is stored, the ECP control box and the multiplug must

be protected against moisture and dirt. A plastic bag may be used to protect the multi plug. Store the control box in a clean dry place.

28 HARDI® COMMANDER OPERATOR’S MANUAL

Operation

Remote 4” pressure gauge

The remote pressure gauge is integrated into the front locker. This gauge measures the working pressure in the boom tubes as close to the nozzles as possible. This pressure reading will always be slightly lower than the reading at the operating unit pressure gauge.

The outputs stated in the nozzle charts are always based on the pressures measured at the nozzle.

Note:

Always adjust pressure when calibrating and spray-

ing according to readings at the Remote pressure gauge.

Self cleaning filters

This filter automatically flushes out particles and chemical deposits, reducing routine maintenance, nozzle plugging and operator exposure. No adjustments are required, but different mesh screens may be installed for various types of products. The mesh size of the filter in use should always be smaller than the flow average of the nozzles used.

5. Replaceable restrictor

6. Return to tank

7. Screw-joint

The self-cleaning filter is operated via the yellow MANIFOLD valve.

IMPORTANT! The yellow MANIFOLD valve should normally be open, but must be closed in the following cases:

1. If rinsing with water from the flush tank and a quantity of spray liquid still remains in the main tank (otherwise the spray liquid will be diluted).

2. If opening the self-cleaning filter and a quantity of spray liquid still remains in the main tank (otherwise there is a risk that spray liquid will flow out).

Choice of correct restrictor for S.C.F.

It is important to have a large flow through the self cleaning filter. This is achieved by choosing the restrictor size in relation to the liquid consumption of the spray boom.

The hose (A) is unscrewed from the self-cleaning filter. Be careful not to lose the seal ball or spring when the restrictor is put in the hose and the hose is refitted. If the required working pressure can not be obtained, the restrictor is too large. 4 restrictors are supplied. Use the green one (largest orifice) first. Then choose the next smaller restrictor, starting with black, then white and finally a red one.

Adjustment of Air Pressure in Pressure Damper (1302 Pump Only)

The air pressure in the damper on the 1302 pump is factory preset at 30 psi (2 bar). This is suitable for nozzle spray pressures between 45 psi (3 bar) and 225 psi (15 bar). If different nozzle pressures are required, set pressure damper at pressures indicated.

1. Empty the sprayer as much as possible. Turn the green pressure valve towards “No Agitation” and spray until air comes out of all nozzles.

2. Remove the tank filter basket.

3. Turn black suction valve towards “Flush tank”.

4. Turn green pressure valves towards “Rinsing nozzle” (optional).

5. Engage and set the pump at approx. 300 r.p.m.

6. When rinsing water corresponding to approx. 10 times the spray liquid residue (see paragraph “Technical Residue”) is used, turn black suction valve towards “Suction from main tank” and operate all valves, so all hoses and components are rinsed.

7. Turn green pressure valve back to “Operating unit” and spray liquid in the field you have just sprayed.

8. Repeat point 3-7 until the flush tank is empty.

5. Disengage pump again.

6. Open Self-cleaning filter again.

WARNING! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always

clean manually with a brush afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed afterwards!

Technical Residue

Inevitably a quantity of spray liquid will remain in the system. It cannot be sprayed properly on the crop, as the pump takes in air when the tank is about to be empty.

This Technical Residue is defined as the remaining liquid qty. in the system as the first clear pressure drop on the pressure gauge is read.

The dilutable residue must be diluted with 10 times the amount of clean water and sprayed to the crop just sprayed before cleaning the sprayer - See “Cleaning the sprayer” (pp. 36-37).

Draining tanks

Operation of the main tank drain valve

WARNING! Before using the top drain, verify that

disposal of waste is done according to chemical

label instructions and local regulations.

Pull the red handle at left hand side of the tank to open the drain valve. The valve is spring loaded to close it, but can be kept open by pulling the string out and upwards in the V-shaped slot. To release and close the drain valve again, pull the string downwards and the valve will close automatically. If draining residues (e.g. liquid fertilizer) into a reservoir, a snap-coupler with hose can rapidly be connected to the drain valve and the liquid safely drained.

B. Rinsing the pump, operating unit, spray lines, etc. in case of interruption in spraying before main tank is empty (e.g. due to rain, etc.).

Flush tank (optional)

1. Close Self-cleaning filter (yellow valve).

2. Turn black suction valve towards “Flush tank”.

3. Turn green pressure valve towards “No Agitation”

4. Engage the pump and spray water from rinsing tank in the field until all nozzle tubes/nozzles are flushed with clean water.

32 HARDI® COMMANDER OPERATOR’S MANUAL

To avoid algae developing in the flush tank, always drain the flush tank when the sprayer is not in use for a long period.

Foam marker tank (optional)

If the sprayer is to stand a few days, it is recommended to drain and flush the foam marker tank to avoid mixed foam from becoming inactive, as once mixed, foam deteriorates rapidly.

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 U.S. GPA at 30 PSI and 5 MPH. The 110° flat 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 need.

Calibration

WARNING:

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 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 field 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 flow of each nozzle. If it puts out more than 10% of its original volume, replace it.

ALWAYS CALIBRATE YOUR

, #818493 for

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

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 on 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).

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 find your exact travel speed.

Select your calibration method- Ounce method or Formula method. Then follow the steps described below:

Ounce Method

1. Determine how long it takes you 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.

Note:

W= • Nozzle spacing (in inches) for broadcast applica-

tion.

• 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.

Calibration / Maintenance

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.

Maintenance - rules of thumb

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

IMPORTANT! of your workday or before servicing is done to avoid unnecessary contact with chemicals.

Always clean the boom at the end

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.

Cleaning the sprayer

Guidelines

1. 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.

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

3. 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.

4. Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining spray liquid.

5. It is good practice to clean the sprayer immediately after use and thereby rendering the sprayer safe and ready for the next pesticide application. This also prolongs the life of the components.

6. It is sometimes necessary to leave spray liquid in the tank for short 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.

7. 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 cannot be damaged by pesticides and their solvents.

36 HARDI® COMMANDER OPERATOR’S MANUAL

Maintenance

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 field you have just sprayed - See paragraph “Use of flush tank and rinsing nozzles”.

Note: It is advisable to increase the forward speed

(double if possible) and reduce the pressure to 20 psi (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 tank and suction filters and clean. Be careful not to damage the mesh. Replace suction filter top. 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.

Before opening the distribution valves and spraying

the liquid out, decide whether this should be done in the field again or on the soakaway.

10. Replace all the filters and nozzles and store the sprayer. If, from previous experiences, it is noted that the solvents in the pesticide are particularly aggressive, store the sprayer with the tank lid open.

Note: If the sprayer is cleaned with a high pressure

cleaner lubrication of the entire machine is recommended.

Cleaning and maintenance of filters

Clean filters ensure:

• Sprayer components such as valves, diaphragms

and operating unit are not hindered or damaged during operation.

• Nozzle blockages do not occur whilst spraying.

• Long life of the pump. A blocked suction filter will

result in pump cavitation.

The main filter protecting sprayer components is the suction filter at the top of the tank. Check it regularly.

Note: The HARDI on the COMMANDER Plus sprayers. It offers both the flushing of internal components and also a highly effective internal rinsing system of the sprayer tank.

Flush & Rinse system is available

If the shock absorbers loose their efficiency or start leaking oil, they should be replaced.

Level indicator adjustment

The level indicator reading should be checked regularly.

When the tank is empty, the float should lie on the stop pin, of the rod, and the O-ring on the indicator should be positioned at the top position line A.

If any deviation is found, pull out the plug B, loosen screws C, and adjust the length of the cord.

3. Pull out the clip A and pull down connecting piece B. The entire valve assembly can now be pulled out.

4. Check cord and valve flap assembly C for wear, replace seal D and assemble again.

5. Assemble the valve assembly again using a new valve seat E. Lubricate O-rings F before assembly.

6. Fit clip A again.

NOTE! Check the function of the valve with clean water before filling chemicals into the tank.

Nozzle tubes and fittings

Poor seals are usually caused by:

Cord renewal, level indicator

If the cord on the level indicator has to be changed, the float guide pole is removed:

1. Remove the tank drain valve (see paragraph “Main tank drain valve”) and loosen the fitting holding the pole in position.

2. Pull the pole down through the drain valve hole till it is free in the top of the tank.

3. The pole can now be taken out of the tank through the filling hole.

DANGER! Do not attempt to enter the tank - the float pole can be removed from outside the tank!

Seal replacement, drain valve

If the main tank drain valve leaks, the seal and seat can be changed the following way.

DANGER! Do not enter the inside of the tank the parts can be changed from underneath the tank!

WARNING! Use eye / face protection mask when dismantling the tank drain valve!

- missing O-rings or gaskets

- damaged or incorrectly seated O-rings

- dry or deformed O-rings or gaskets

- foreign bodies

In case of leaks:

DO NOT overtighten. Disassemble, check condition and position of O-ring or gasket. Clean, lubricate and reassemble.

The O-ring must be lubricated ALL THE WAY ROUND before fitting on to the nozzle tube. Use non-mineral lubricant.

For RADIAL connections only hand-tighten them.

For AXIAL connections, a little mechanical leverage may be used.

1. Make sure the tank is empty and clean.

2. The valve must be closed and the string loose.

49HARDI® COMMANDER OPERATOR’S MANUAL

Maintenance

Adjustment of 3-way-valve (suction)

The MANIFOLD valve can be adjusted if it is too tight to operate - or if it is too loose (= liquid leakage).

Correct setting is when the valve can be operated smoothly by one hand

Use a suitable tool and adjust the toothed ring inside the valve as shown on the drawing.

Off-season 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 under “Cleaning of 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.

8. Remove the glycerine-filled pressure gauges and store them in a vertical position in frost free conditions.

Apply a thin layer of anti-corrosive oil (e.g. SHELL

9. ENSIS FLUID, CASTROL RUSTILLO or similar) on all metal parts. Avoid oil on rubber parts, hoses and tires.

10. Fold the boom in transport position and relieve

pressure from all hydraulic functions.

11. All electric plugs and sockets are to be stored in a

dry plastic bag to protect them against moisture, dirt and corrosion.

12. Remove all the control boxes (including any rate

controller/monitor control box and display) from the tractor and store them in a dry and clean location.

13. Wipe hydraulic snap-couplers clean and fit the dust

caps.

14. Apply grease on all hydraulic ram piston rods which

are not fully retracted in the barrel to protect against corrosion.

15. Jack up the axle and place wooden blocks under

the wheels to prevent moisture damage and deformation of the tires. Tire black can be applied to the tire side walls to preserve the rubber.

2. Renew 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. Remember to drain the flush tank also.

4. Pour appr. 13 gal. (50 liters) anti-freeze mixture consisting of 1/3 automotive anti-freeze and 2/3 water into the tank.

5. Engage the pump and operate all valves and functions on the MANIFOLD system, ECP unit, CHEM FILLER, etc. allowing the anti-freeze mixture to be distributed around the entire circuit. Activate the ECP main on/off switch and distribution valves so the antifreeze is sprayed through the nozzles as well.

The anti-freeze will also prevent O-rings, seals,

diaphragms, etc. from drying out.

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

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

Preparation after off-season storage

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

1. Remove the cover. (If fitted)

2. Remove the blocks from under the wheels and

adjust the tire pressure.

3. Wipe off the grease from hydraulic ram piston rods.

4. Fit the pressure gauges again. Seal with Teflon tape.

5. Connect the sprayer to the tractor, including hydrau-

lics and electrics.

6. Check all hydraulic and electric functions.

7. Empty the tank for remaining anti-freeze.

8. Rinse the entire liquid circuit on the sprayer with

clean water.

7. Lubricate all lubricating points according to the lubricating scheme - regardless of intervals stated.

Troubleshooting

Operational problems

In cases where breakdowns have occurred, the same factors always seem to be in question:

1. Minor leaks on the suction side of the pump will reduce the pump capacity or stop the suction completely.

2. A clogged suction filter will hinder or prevent suction so that the pump does not operate satisfactorily.

3. Clogged up pressure filters will result in increasing pressure at the pressure gauge but lower pressure at the nozzles.

4. Foreign bodies stuck in the pump valves with the result that these cannot close tightly against the valve seat. This reduces pump efficiency.

5. Poorly reassembled pumps, especially diaphragm covers, will allow the pump to suck air resulting in reduced or no capacity.

6. Hydraulic components that are contaminated with dirt result in rapid wear to the hydraulic system.

Therefore ALWAYS check:

1. Suction, pressure and nozzle filters are clean.

2. Hoses for leaks and cracks, paying particular attention to suction hoses.

3. Gaskets and O-rings are present - and in good condition.

4. Pressure gauge is in good working order. Correct dosage depends on it.

5. Operating unit works properly. Use clean water to check.

6. Hydraulic components are maintained clean.
