1 Important safety instructions

For your own safety

The appliance must

only be used by persons, who have been instructed in its correct usage and explicitly commissioned with the task of operating it
only be operated under supervision
not be used by children
not be used by mentally or physically disabled persons

CAUTION!

High-pressure water jets can be dangerous if misused. The jet must not be directed at persons, animals, live electrical equipment or the cleaner itself.

Wear protective clothing, ear protection and safety goggles.

Do not use the cleaner when other people without protective clothing are in the working area. Do not direct the jet towards yourself or towards other persons in order to clean clothes

or footwear. Do not direct the jet towards live animals.

During operation of the cleaner, recoil forces are produced at the spraying device and, when the spray lance is held at an angle, a torque is also created. The spraying device must therefore be held firmly in both hands.

General

Use of the high-pressure cleaner is subject to the applicable local regulations.

Besides the operating instructions and the binding accident prevention regulations valid in the country of use, observe recognised regulations for safety and proper use.

Do not use any unsafe work techniques.

Do not tie the trigger handle open.

Transport

For safe transport in and on vehicles we recommend preventing the equipment from sliding and tilting. Secure it with belts.

For transport at temperatures around or below 0^ , anti-freeze liquid should be drawn into the pump and boiler beforehand (see chapter 6).

Before starting the cleaner

If your machine is a 3 phase version and has been supplied without a plug have it fitted with a suitable 3 phase plugwith an earth conductor by an electrician.

Each time prior to putting the appliance into service, always check the power supply cord and the other important parts of the appliance, such as the high-pressure hose and the spray gun. Do not operate the appliance if any of these parts are damaged.

Set up the appliance such that the mains connector is readily accessible.

Regularly check whether the mains lead is damaged or shows signs of ageing. Use the high-pressure cleaner only when the mains power lead is in a safe condition.

If the mains power lead is damaged, to avoid hazards, this must be replaced either by the manufacturer or through his customer service or a similarly qualified person.

CAUTION!

Unsuitable extension leads can represent a source of danger. Always unwind lead from the reels completely to prevent the mains power lead overheating.

Connectors and couplings of power supply cords and extension leads must be watertight.

When using an extension lead, check the minimum cross-sections of the cable:

Cable length m	Cross section
	<16 A	<25 A
up to 20 m	ø1.5mm²	ø2.5mm²
20 to 50 m	ø2.5mm²	ø4.0mm²

Check the rated voltage of the high-pressure cleaner before connecting it to the mains power supply. Ensure that the voltage shown on the rating plate corresponds to the voltage of the local mains power supply.

It is important that the electrical connection for this appliance has been installed by an electrician and in compliance with IEC 60364 and the country-specific regulations.

We recommend that the electrical connection to this appliance should incorporate

• either a fault current circuit breaker, which cuts off the mains voltage if the fault current exceeds 30mA for 30 ms,
• or an earth resistance meter.

Check that cleaning will not result in dangerous substances (e.g. asbestos, oil) being washed off the object to be cleaned and harming the environment.

Do not clean delicate parts made of rubber, fabric, etc. with the 0^ jet. Keep some distance between high pressure nozzle and surface in order to prevent the surface from damage.

Do not use the high-pressure hose for lifting loads.

The maximum permissible working pressure and temperature are printed on the high-pressure hose.

Store the cleaner where it will not be exposed to frost or use anti-freeze

Never operate the cleaner without water. Even brief shortages of water result in severe damage to the pump seals.

Water connection

This high pressure washer/cleaner is only allowed to be connected with the drinking water

mains, when an appropriate backflow preventer has been installed, Type BA according to EN 1717. If the back flow preventer hasn't been supplied, one can be ordered from your dealer. The length of the hose between the backflow preventer and the high pressure washer must be at least 6 metres (min diameter 3/4 inch) to absorb possible pressure peaks. Operation by suction (for example from a rainwater vessel) is carried out without backflow preventer. Contact your dealer for suction set recommendations. As soon as water has flown through the BA valve, this water is not considered to be drinking water any more.

Operation

Keep cabinet closed during operation.

Do not damage the mains power lead (e.g. by driving over it, pulling or crushing it).

Disconnect the power cord by pulling the plug only (do not pull or tug the power cord).

IMPORTANT!

This appliance has been devised for use with cleansing agents that are supplied and recommended by the manufacturer. The use of other cleansing agents or chemicals can impair the safety of the appliance.

CAUTION!

The appliance is intended to be used with heating oil EL or diesel oil. Unsuitable fuels (e.g. petrol) must not be used as they can represent a source of danger.

If the machine is to be operated at fuel stations or in other potentially hazardous areas, the machine may only be employed outside the hazard areas defined in the German "Technical Guidelines for Inflammable Fluids" applicable at the point of use due to the potential explosion hazard posed by the burner.

When setting up the appliance indoors, always ensure suitable ventilation and that the exhaust gases are expelled in a suitable way. We will be glad to provide tips for connection systems, on request.

If the machine is to be connected to a flue gas stack, then local building regulations must be observed. We will be glad to provide tips for connection systems, on request.

CAUTION!

Beware of hot water and steam discharge up to 150^ when operating in steam stage.

CAUTION!

Do not touch or cover the exhaust. Risk of burns, sand fire.

Do not touch, cover or place hose or cord over the chimney. Danger for persons, risk of overheating and fire.

Electrical equipment

CAUTION!

Never spray electrical equipment with water: danger for persons, risk of short-circuiting.

Switching on the cleaner may cause voltage fluctuations.

Voltage fluctuations should not occur if the impedance at the transfer point is less than 0.15 . If in doubt ask your local electricity supplier.

Maintenance and repair

CAUTION!

Always remove the plug from the mains plug socket before cleaning or carrying out maintenance work on the cleaner.

Carry out only the maintenance operations described in the operating instructions. Use only original Nilfisk-ALTO spare parts.

Do not make any technical modifications to the high-pressure cleaner.

Ensure that the machine is regularly serviced by Authorised Nilfisk-ALTO dealers in accordance with the maintenance plan. Failure to do so will invalidate the warranty.

CAUTION!

High-pressure hoses, fittings and couplings are important for

the safety of the cleaner. Use only high-pressure parts approved by the manufacturer!

The mains power lead must not differ from the version specified by the manufacturer and may only be changed by an electrician.

Please contact the Nilfisk-ALTO service department or an authorised specialist work-shop for all other maintenance or repair work!

Testing

The cleaner conforms to the German "Guidelines for Liquid Spray Jet Devices". The high-pressure cleaner must be subjected to a safety examination in accordance with the "Accident Prevention Regulations for Working with Liquid Spray Jet Devices (BGVD15)" as required, but at least every 12 months, by an authorised inspector.

After all repairs or modifications to electrical equipment, the protective conductor resistance, the insulation resistance and the leakage current must be measured. Furthermore, a visual inspection of the mains power lead, a voltage and current measurement and a function test must be carried out. Our after-sales service technicians are at your disposal as authorised inspectors.

The complete „Accident Prevention Regulations for Working with Liquid Spray Jet Devices“

are available from the Carl Heymanns Verlag KG, Luxemburger Strasse 449, 50939 Cologne or from the appropriate association of employers' liability insurances.

The pressure-bearing parts of this high-pressure cleaner have been manufactured in accordance with § 9 of the German Pressure Vessels Ordinance and successfully subjected to a pressure test.

Safety devices

Unacceptably high pressure is fed back without residual pressure via a bypass line into the intake line of the pump when the safety device is tripped.

If the conveying capacity falls below a fixed value, the built-in flow monitor automatically switches off the oil burner. The oil burner is set to continuous ignition. As an additional protection mechanism, a thermo-sensor is integrated in the chimney of the heat exchanger. As such, the appliance cannot overheat.

The safety devices are factory set and leaded, and must not be adjusted.

3 Before starting the cleaner

3.1 Setting up the cleaner

Every fuel-burning appliance, such as pressure washers, depends upon a proper mix of fuel and air (by weight) for proper combustion. Therefore some adjustment of the air regulation to the burner may be necessary to take account of altitude and the resulting air pressure. This is true whether your fuel is Kerosene or Diesel.

Your Nilfisk-ALTO hot water pressure washer was thoroughly tested and adjusted for

optimum performance before it left our factory. The factory is located at approximately 140m (450 ft) above sea level, and the combustion settings are optimal for that elevation.

If your location is higher than 1200m (3900 ft) above sea level, your burner may require re-adjustment for proper performance and best fuel economy. Contact your Dealer or Nilfisk-ALTO for assistance.

3.2 Before use

1. Before using the cleaner for the first time, check it carefully to detect any faults or damage.
2. Run the machine only when it is in perfect condition.
3. The slope on which the high pressure cleaner is placed must not exceed more than 10^ in any direction.
4. Fill up detergent tank with prediluted detergent.

Capacity see chapter 9.4 Technical Data

3.3 Fill up detergent tank

3.4 Antiscale

The Nilfisk Alto Antiscale dosing system is set by the factory. To adjust the water hardness we recommend that the inlet water is tested accordingly.

Use the schematic to find the right dosage of No Scale/anti stone and water, and add the mixture to the antiscale tank.

Machine flow L/h	Pump size ml/h	°dH	°f	°e	Dosage
600	35	0-12	0-21,5	0 - 15	1:2 = 12ml/h
600	35	12-30	21,5 - 53,7	15 - 37,5	Pure = 35ml/h
700	35	0-12	0-21,5	0 - 15	1:1 = 17ml/h
700	35	12-30	21,5 - 53,7	15 - 37,5	Pure = 35ml/h
800	35	0-12	0-21,5	0 - 15	1:1 = 17ml/h
800	35	12-30	21,5 - 53,7	15 - 37,5	Pure = 35ml/h

3.5 Fill up fuel tank

NOTE!

At temperatures below 8^ , the fuel oil begins to solidify (paraffin precipitation). This can lead to difficulties in starting the burner. Before the winter period either add a solidification point / flow improver (available from the fuel oil trade) to the fuel or use winter diesel fuel.

With the machine cold:

1. Pour fuel (fuel oil EL, or Diesel oil DIN 51 603) into the fuel tank.

The fuel must be free from contamination.
Tank capacity see chapter 9.4
Technical data.

Be careful not to damage the fuel tank filter to avoid dirt entering in the tank

1. Put the quick connector of the high pressure hose onto the nipple on the cleaner. ^1)

3.6 Connecting the high pressure hose

3.7 Connecting the water supply

In the case of poor water quality (sand, etc.), we recommend that a fine water filter is fitted in the water inlet.

We recommend the use of a textile-reinforced water hose with a nominal diameter of min. 3/4'' (19 mm).

1. Rinse the water supply hose briefly in order to prevent sand an other dirt particles entering into the machine.
2. Connect water supply hose to the machine.
3. Open water tap.

NOTE!

See chapter 9.4 Technical Data for required quantity of water and water pressure.

3.8 Electrical connection

Before connecting devices with voltage changeover¹⁾: Check that the pre-selected voltage on the machine corresponds with the voltage of the electrical installation. Otherwise the electrical

devices of the machine can be destroyed.

CAUTION!

When using cable reels:

1. Due to the risk of overheating and fire, always unwind the power supply cord fully.

The cleaner may only be connected to a correctly installed electrical installation.

1. Observe safety instructions in chapter 1.

8. Set the desired concentration of cleansing agent at the cleansing agent dosing facility.

9. Spray the object to be cleaned.
10. Allow the cleaning agent to work, depending on the degree of soiling. Then rinse off with the high pressure spray jet.

CAUTION!

Never allow cleaning agent to dry on the surface to be cleaned. The surface may be damaged.

5 Applications and methods

5.1 Techniques

Efficient high pressure cleaning is achieved by following a few guidelines, combined with your own personal experience of specific cleaning tasks. Accessories and detergents, when correctly chosen, can increase the efficiency of your pressure washer. Here is some basic information about cleaning.

5.1.1 Soaking

Encrusted or thick layers of dirt can be loosened or softened by a period of soaking. An ideal method within agriculture – for example, within pig sties. The soaking method can be achieved by use of foam or simple alkaline detergent. Let the product lie on the dirty surfaces for around 15 minutes before pressure washing. The result will be a much quicker high pressure cleaning process.

5.1.2 Detergent and Foam

Foam or detergent should be applied onto dry surfaces (not in direct sun light) so that the chemical product is in direct contact with the dirt. Detergents are applied from bottom to top, for example on a car bodywork, in order to avoid "super clean" areas, where the detergent collects in higher concentration and streams downwards. Let the detergent work for several minutes before rinsing but never let it dry on the surface being cleaned.

5.1.3 Temperature

Detergents are more effective at higher temperatures. Greases, oils and fats can be broken down more easily at higher temperatures also. Proteins can be cleaned at temperatures of around 60^ . Oils, traffic film around 70^ , and grease can be cleaned at 80^ - 90^ .

5.1.4 Mechanical Effect

In order to break down tough layers of dirt, additional mechanical effect may be required. Special lances and rotary or wash brushes offer this supplementary effect that cuts through dirt.

5.1.5 High Water Flow or High Pressure

High pressure is not always the best solution and high pressure may damage surfaces. The cleaning effect also depends upon water flow. Pressure levels of around 100 bar may be sufficient for vehicle cleaning (in association with hot water). Higher flow levels give the possibility to rinse and flush away large amounts of dirt easily.

5.2 Some typical cleaning tasks

5.2.1 Agriculture

Task	Accessories	Method
Stables Pig Pens, Sties Cleaning of walls, floors and equipment Disinfectant	Chemical Foam Injectors Foam lance Powerspeed lance Floor Cleaner Detergents Universal Alkafoam Disinfectant DES 3000	1. Soaking – apply foam to all surfaces (bottom to top) and wait for approx. 15 minutes. 2. Remove the dirt from surfaces with the high pressure lance or chosen accessory. Again, clean from bottom to top on vertical surfaces. 3. To flush away large quantities of dirt, change to low pressure mode and use the higher flow to push away the dirt. 4. Use recommended disinfectant products and methods to ensure hygiene. Apply DES 3000 disinfectant once the surfaces are perfectly clean.
Machinery Tractors ploughs etc.	Detergent injection Powerspeed lances Curved lances and under chassis washers Brushes	1. Apply detergent to vehicle or equipment surfaces in order to soften up dirt and grime. Apply from bottom to top. 2. Proceed with cleaning using the high pressure lance. Clean again from bottom to top. Use accessories to clean in difficult to reach places. 3. Clean fragile areas such as motors, rubber at lower pressure levels to avoid damage.

5.2.2 Vehicle

Task	Accessories	Method
Vehicle bodywork	Standard lance Detergent injection Curved lances and underchassis washers brushes Detergents Aktive Shampoo Aktive Foam Sapphire Super Plus Aktive Wax Allosil RimTop	1. Apply detergent to vehicle or equipment surfaces in order to soften up dirt and grime. Apply from bottom to top. In cases of particularly dirty vehicles, pre-spray with a product such as Allosil in order to remove traces of insects etc, then rinse at low pressure and apply normal car cleaning detergent. Let detergents settle for 5 minutes before cleaning off. Metallic surfaces can be cleaned using RimTop. 2. Proceed with cleaning using the high pressure lance. Clean again from bottom to top. Use accessories to clean in difficult to reach places. Use brushes in order to add a mechanical cleaning effect. Short lances can help for cleaning of motors and wheel arches. Curved lances or undercarriage washers can be valuable for the cleaning of car underchassis and wheel arches. 3. Clean fragile areas such as motors, rubber at lower pressure levels to avoid damage. 4. Apply a liquid wax using the pressure washer in order to protect the bodywork from pollution.

5.2.3 Buildings and Equipment

Task	Accessories	Method
General surfaces	Foam injectors	1. Apply thick foam over the surfaces to be cleaned. Apply on dry surfaces. Apply from top to bottom on vertical surfaces. Let the foam act for up to 30 minutes for the optimal effect.
Metallic equipment	Standard lance
	Curved lances
	Tank cleaning head
	Detergents	2. Proceed with cleaning using the high pressure lance. Use applicable accessories. Use high pressure to dislodge large amounts of incrusted dirt or grime. Use lower pressure and high water volume in order to rapidly flush away loose dirt and rinse surfaces.
	Intensive
	J25 Multi
	Combi Aktive
	Alkafoam
	Disinfectant	3. Apply DES 3000 disinfectant once the surfaces are perfectly clean.
	DES 3000
		Areas covered by amounts of loose dirt, such as animal remains in slaughterhouses, can be cleaned by using high water flow to flush away the dirt to evacuation pits or drains.
		Tank cleaning heads can be used to clean barrels, vats, mixing tanks etc. Cleaning heads may be hydraulically or electrically powered and give the possibility for automatic cleaning without a constant user.
Rusted or damag- es surfaces prior to treatment	Wet Sandblasting equipment	1. Connect the sandblasting lance to the pressure washer and place the suction tube in the sand.
		2. Always wear protective equipment during sandblast-ing.
		3. Spray the surfaces to be treated with the mix of water and sand. Rust, paint etc will be stripped off.

These are merely several examples of cleaning tasks that can be solved by a pressure washer in association with accessories and detergents. Each cleaning task is different. Please consult your local dealer or Nilfisk-ALTO representative in order to discuss the best solution for your own cleaning tasks.
