K Sprayer use The HARDI MASTER sprayer is for the application of crop protection chemicals and liquid fertilisers.

The equipment must only be used for this purpose. It is not allowable to use the sprayer for other purposes.

If no local law demands that the operator must be certified to use 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 your spray job. T102-0018

GB 04 02 MA Description

Unloading the sprayer from the truck Lifting points For the unloading of the sprayer, you need a crane or a fork lift.

When unloading with a crane please observe the two lifting points (A) as shown on the picture below, and make sure that the straps or belts used for lifting are strong enough.

A A T102-0025

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 fertilisers discoloring the enamel.

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.

Ball check valve (8) should normally be open, but can be closed in situations where return flow is to be avoided.

NOTE! If ball check valve is closed the self-cleaning filter is inoperative!

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

4 restrictors are supplied. Use the green one (largest orifice A first).

Hose N is removed from the filter. Be careful not to loose the seal. The restrictor is placed in the hose and the hose is mounted again.

If the required working pressure cannot be obtained, the restrictor is too large. Choose a smaller restrictor. Start with a black one, then a white and finally a red one. T020-0020

When cleaning the filter remove hose N and the hose at the safety valve and check there are no residues.

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.

Repair of the bag If the air bag is damaged it can be repaired by sewing or gluing a patch on it. A repair kit is available; HARDI ref. no. 728746.

Oil cooler The cooler under the fan must be inspected externally at least yearly and cleaned if necessary. Remove the bag and check that the cooler ribs are clean. A pressure cleaner can be used to clean the ribs. When the bag is replaced, unfold the boom to check it is centred and angle the air outlet forward to check there is no slack in the bag.

Hydraulic transmission If the hydraulic motor has been dismantled or replaced, the following start-up procedure has to be done:

1. The boom needs to be unfolded so choose a location where this is possible.

2. Remove the snap coupler from hy. motor the drain line and place the hose in a small container. Set the valve for blower fan revolutions at or near minimum and with the tractor engine at idle, unfold the boom.

3. Adjust valve A for blower fan revolutions so the fan rotates between 300 to 500 r/min for 5 minutes or until oil comes from the drain line. The sprayer hydraulics are now filled with oil and the valve can be set to maximum and tractor r/min in- creased to check for possible leakage.

4. Check oil pressure filter (if fitted) indicates green (not clogged).

5. Replace the drain line snap coupler. Check the tractor hydraulic oil level and top up if needed.

GB 15 02 MA Fault finding

Operational problems In cases where breakdowns have occurred, the same factors always seem to come into play:

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 functions properly. Use clean water to check. 6. Hydraulic components are maintained clean.
