1 Important safety instructions

For your own safety
The high-pressure cleaner should only be used by authorized persons who have been instructed in its use.
Although extremely easy to operate, children should not be allowed to use the cleaner.
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 recognized regulations for safety and proper use.
- Do not use any unsafe work techniques.
Transport
Transport of the high-pressure cleaner is easy on its large wheels.
For safe transport in and on vehicles we recommend preventing the equipment from sliding and tilting. Secure it with tie-downs and apply the parking brake on the castor wheel.
For transport at temperatures around or below freezing 0^ (32^) , anti-freeze should be drawn into the pump beforehand (see chapter 6).
Before starting the cleaner
If your 3-phase cleaner was supplied without a plug, have it fitted with a suitable 3-phase plug with ground, by a qualified electrician.
Before use, check that the high-pressure cleaner is safe and in proper condition.
Regularly check whether the power cord is damaged or shows signs of ageing.
Use the high-pressure cleaner only when the power cord is in a safe condition. (risk of electric shock using damaged cord!).
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 power supply.
We strongly recommend that the power supply to the high pressure cleaner be connected via a residual current circuit breaker. This device stops the supply of electricity if the leakage current to the ground exceeds 30mA for 30 ms or it has an ground tester circuit.
Please observe the regulations and provisions applicable in your area. Before putting the high-pressure cleaner into service, carry out a visual check of all the major components.
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 appropriate protective clothing and eye protection.
Do not direct the jet towards yourself or towards other persons in order to clean clothes or footwear.
During operation of the cleaner, recoil forces are produced at the gunvalve and spray lance and, when the spray lance is held at an angle, a torque is also created. The gunvalve and spray lance must therefore be held firmly in both hands.
Do not use the cleaner when other people without protective clothing are in the working area.
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.
NOTE!
The maximum permissible working pressure and temperature are printed on the high-pressure hose.
Do not use the cleaner if the power cord or high-pressure hose is damaged.
Ensure adequate air circulation. Do not cover the cleaner or operate it in inadequately ventilated rooms!

Store the cleaner where it will not be exposed to frost!
Never operate the cleaner without water. Even brief shortages of water result in severe damage to the pump seals.
Operation
Keep cabinet and service door closed during operation.
CAUTION!
Unsuitable extension cords can represent a source of danger. Always unwind cord from the reels completely to prevent the power cord overheating.
Connectors and couplings of extension cords must be watertight.
Extension cords are not recommended, however if necessary refer to the following recommendations:
| Cord length m | Cross section | |
| up to16 A | up to 25 A | |
| up to 20 m (US: 30 ft) | ø1.5mm² | ø2.5mm² |
| (US: 50 ft) | 14 gauge | 12 gauge |
| (US: 75 ft) | 12 gauge | 10 gauge |
| 10 gauge | not recommended | |
| 20 to 50 m | ø2.5mm² | ø4.0mm² |
Do not damage the power cord (e.g. by driving over it, pulling or crushing it).
Disconnect the power cord by grasping the plug only (do not pull or tug the power cord).
CAUTION!
Unsuitable fuels (e.g. gasoline) must not be used as they can explode and catch fire.
Use clean fuel only, free of moisture and contamination. Contact your dealer for fuel source and type recommendations.
This machine can be used with Bio-Diesel (DIN 51606). However, our experience has shown that the fuel quality is often outside
the recognized standards. An organic product like Bio-Diesel can be affected by long-term storage (e.g. over the winter), extreme temperatures, or improper transportation. When the condition of the fuel is outside the standards, trouble may occur which cannot be covered by the Warranty.
english
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.
If the machine is to be operated indoors, the local building regulations must be observed for the discharge of the exhaust fumes into the atmosphere. Ensure an adequate supply of fresh air.
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!
Do not touch or cover the exhaust. Risk of burns and fire.

Electrical equipment
CAUTION!
Never spray electrical equipment with water: risk of electrical shock and short-circuit.
The cleaner may only be connected to a correctly installed plug socket.
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.
english Maintenance and repair
CAUTION!
Always remove the plug from the power supply 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 authorized Nilfisk-Alto dealers in accordance with the maintenance plan. Failure to do so will void 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 power cord must not differ from the version specified by the manufacturer and may only be
changed by an electrician.
Please contact your local authorized Nilfisk-Alto equipment distributor for all other maintenance or repair needs!
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" 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.
Unloader valve
Pump pressure is reduced by means of an "unloader valve" which returns water to the inlet side of the pump at a minimum pressure. The point at which this occurs is set and sealed at the factory and must not be adjusted.

3.1 Transport and assembly

- The safest way to lift the machine is to use a fork-lift truck. The arrows in the illustration indicate the best places to position the fork.
- It is also possible to lift the ma
3.2 Set the brake
chine by hand from the pallet. Due to the weight this work should be done by at least three persons.
CAUTION!
Do not hold the plastic tank to lift the machine as it could become detached from the frame.
The best places to hold the machine are
on the handle
on the frame between the front wheels and the guide rollers.
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 supply to the burner may be necessary to take account of altitude and the resulting air pressure. This is true whether your fuel is 'Natural gas', Propane 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 200m (650 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.
- Before using the cleaner for the first time, check it carefully for any faults or damage.

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 up by a period of soaking. This is for example an ideal method within agriculture – for example, within pig sties. The ideal soaking method can be achieved by using foam or simple alkaline detergent. Let the product lie on the dirty surfaces for about 30 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 so that the chemical product is in direct contact with the dirt. Detergents are applied from bottom to top, for example on a automobile bodywork, in order to avoid "super clean" areas, where the detergent may collect in higher concentrations and streams downwards. Let the detergent work for several minutes before rinsing before rinsing and never let it dry on the surface being cleaned.
english
5.1.3 Temperature
Detergents are more effective at higher temperatures. Greases, oils and fats can be broken down more effectively at higher temperatures also. Proteins can be cleaned at temperatures of around 60^ (140^) . Oils and traffic film around 70^ (158^) , and grease can be cleaned at 80^ - 90^ (176 - 194^) .
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 may also damage surfaces. The cleaning effect also depends upon water flow. Pressure levels of around 100 bar (1450 psi) may be sufficient for vehicle cleaning (in association with hot water) and higher flow levels give the ability 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. 30 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.

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 Standard lance | 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 | Curved lances | 2. Proceed with cleaning using the high pressure lance. Use applicable accessories. Use high pressure to dislodge large amounts of incrusted dirt or grime. |
| Tank cleaning head | Use lower pressure and high water volume in order to rapidly flush away loose dirt and rinse surfaces. | |
| Detergents | 3. Apply DES 3000 disinfectant once the surfaces are perfectly clean. | |
| Intensive | Areas covered by amounts of loose dirt, such as animal remains in slaughterhouses, can be removed by using high water flow to flush away the dirt to evacuation pits or drains. | |
| J25 Multi | 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. | |
| Combi Aktive | ||
