3.0 Connections

EN

3.1 Water connection

The water input is connected at the back of the machine. The machine can be connected directly to the mains water supply, or it can work as a self-priming unit*).

For direct water connection the inlet hose must be at least 6m long, and the water temperature must not exceed 65^ . Please note that connection to the public water supply may entail mounting of a float chamber.

If there is sand or other impurities in the water, it is advisable to provide an external water filter in addition to the internal filter situated behind the quick coupling (see accessory catalogue).

3.2 Oil supply

Connect the hydraulic motor to a hydraulic supply with a capacity of 43I / min by 94-100 bar.

If the return pipe pressure exceeds 1.5 bar the drain pipe should be conducted separately.

*) With cold water (up to 5^ ) the cleaner will operate satisfactorily with up to a 5 metre difference of level between cleaner and water supply. The pump and the inlet hose must be connected to the water supply before starting up. When working with hot water (65^) the cleaner must be below or on a level with the point of water supply. Working with hot water and connected to high pressure hoses longer than 10m or inlet hoses shorter than 6m , the cleaner must be equipped with a float chamber. The same applies if the outlet of the cleaner is connected to a tube system.

4.0 Standard equipment

The cleaner is delivered with a double lance and a spray handle together with high pressure hose as standard equipment. The low pressure tube is equipped with a flat jet nozzle 6530 and the high pressure hose with a flat jet nozzle 1506. The first two figures of the nozzle reference number indicate the spray angle in degrees and the last two indicate the water flow in l/min. at a pressure of 20 bar and a temperature of 20^ . The equivalent hole diameters for nozzle 1506 is 1.6mm and for nozzle 6530 is 3.6mm . Do not replace with nozzles of a smaller diameter. The maximum working pressure and temperature are printed on the standard high pressure hose. Only use Nilfisk-ALTO high pressure hoses. In case of damage, arrange for Nilfisk-ALTO service engineers to repair it. Do not attempt to repair it yourself.

The thrust on the nozzle is for:

4403KOS

47N

(4.8 k p)

As the thrust forms an angle with the spray lance, the spray handle is subject to torque.

5.0 Operation

EN

5.1 Starting-up procedure

1. Check the oil level in the oil glass. The level should be maintained between the MIN. and MAX. marks.
2. Run water through the inlet hose before connecting, in order to remove possible impurities in the hose. Connect the hose.
3. Connect the quick coupling (a) of the high pressure hose to the outlet socket.
4. Check the input end of the spray lance (b) for possible impurities. Pull forward the grey trigger (c) of the spray handle. Connect the input end of the spray lance to the quick coupling. Release the grey trigger.
5. Press the trigger of the spray handle (d) and allow the water to run, until the system has been completely vented. For self-priming it is recommended to open the regulating valve (e) during the venting.
6. Release the trigger of the spray handle (d) and turn on the hydraulic supply. The pump will now be in idle motion.
7. For cleaning at high pressure press home the trigger of the spray handle after having closed the regulating valve.
8. For cleaning at low pressure open the regulating valve.

5.2 Stopping

1. Turn off the hydraulic supply.
2. Turn off the water supply and disconnect the hoses.
3. Do not disconnect the high pressure hose, until the cleaner has cooled down and stopped.

5.3 Regulation of pressure/water capacity

When working at the maximum working pressure the regulating valve of the spray lance must be completely closed, and the valve for regulation of the water capacity must be unscrewed (in the direction indicated by the arrow).

The water capacity is continuously variable between min. and max. according to the diagram below.

Close the spray handle, screw in the valve for regulation of the water capacity (in the opposite direction of that indicated by the arrow). This corresponds to a working pressure of 40 bar and a water capacity of about 9l / min

If increased water output is required, turn the valve in the direction indicated by the arrow, until the required amount is reached. 1 turn is equivalent to a rise of pressure of approx. 50 bar.

If fully reduced pressure with maximum water output is required, open the regulating valve. The water will now flow from both tubes at a pressure of approx. 5 bar.

This can be done irrespective of the adjustment of the valve for regulation of the water capacity.

Pressure (bar)

Operation and storage in frosty weather (below 0^ ).

Never leave the cleaner unless it has been emptied of water, not even for a short period. Empty the cleaner in the following way:

1. Disconnect and empty both the water supply and the high pressure hoses.
2. Start the pump and allow it to run until it is empty.

If the cleaner is not stored in a frost-proof place between operations, it should be protected from frost in the following way:

1. Disconnect the lance.
2. Start the machine and allow it to run without water.
3. Place the suction hose into a container of anti-freeze.
4. Draw in the antifreeze from the container by activating the spray handle. Having placed the spray handle above the antifreeze funnel, open and close it a few times, so that the antifreeze can circulate.
5. Remove the inlet hose from the container. Activate the spray handle and allow the rest of the antifreeze to run back into the container.

NB! The antifreeze will be diluted with water and will after some time lose its effect.

IMPORTANT:

To avoid damage always ensure that the cleaner, the hoses and the spray lance are unfrozen before restarting. Place the cleaner and the accessories in a warm place for some time before starting up.

7.0 Maintenance

EN

8.0 Safety

EN

7.1 Changing of oil

The oil should be changed after each 1000 hours' use.

Remove the cover of the oil glass. Unscrew the drain plug. Allow the oil to run out and clean the drain plug of impurities. Screw in the plug and refill the pump with fresh oil through the oil glass. Holds approx. 1 l.

From Nilfisk-ALTO the pump is filled with zincless hydraulic oil - Nilfisk-ALTO Pump Oil 100. When refilling and changing the oil this or an oil with the following specifications should be used:

ISO no. 100

Viscosity index (VI) min. 130

Pour point below -30^

7.2 Sludge container

The used oil is caught in a sludge container, which should be emptied before it is completely full. The oil must not be reused in the pump.

7.3 Water filter

To avoid debris entering the high pressure pump a water filter is fitted at the water inlet. This filter must be taken apart and cleaned regularly. The intervals between cleaning depend on the purity of the water. The filter can be removed, when the quick coupling has been unscrewed.

7.4 Couplings

To avoid leakages and damage to the quick couplings on hoses, spray handle and spray lance it is necessary to clean and lubricate the parts regularly with a little oil or grease.

Your Nilfisk-ALTO cold water cleaner is designed and manufactured to comply with the very latest labour regulations.

Nevertheless, the following instructions must be strictly observed.

1. Always hold the spray handle and lance firmly in both hands during operation at high pressure.

1. Never direct the high pressure spray towards people or electrical devices.

1. When not in use; lock the spray handle.

1. Only use the hoses and nozzles approved by Nifisk-ALTO.
2. Do not disconnect the high pressure hose until the cleaner has cooled down and stopped.
3. Don't attempt to touch nozzle nor water jet during operation.
4. Never tie knots in or kink the high pressure hose as it may be damaged and consequently burst.
5. Do not leave your machine exposed to frost. However if cleaner, hose or lance should become frozen do not use until they have thawed.
6. The high pressure pump features a safety valve, the adjustment of which SHOULD NOT BE CHANGED.
7. The machine should only be used by people who have been properly instructed.
