Options / model variants Original instruction NEPTUNE 1, NEPTUNE 2 NEPTUNE 2 Special 1 Important safety instructions Symbols used to mark instructions Before using the high-pressureclean- er, be sure to also read the enclosed operating instruc- tions and keep them within reach at all times. For your own safety The appliance must – only be used by persons, who have been instructed in its correct usage and explic- itly commissioned with the task of operating it – only be operated under su- pervision – 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 equip- ment 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 per- sons 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 instruc- tions and the binding accident prevention regulations valid in the country of use, observe rec- ognised 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 ve- hicles we recommend prevent- ing the equipment from sliding and tilting. Secure it with belts. For transport at temperatures around or below 0°C, 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 electri- cian. 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 appli- ance 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. Safety instruc- tions in these operating instruc- tions which must be observed to prevent risks to persons are marked with this danger symbol. This symbol is used to mark safety in- structions that must be observed to pre- vent damage to the machine and its performance. This indicates tips and instruc- tions to simplify work and to en- sure safe operation.6

Options / model variants Original instruction NEPTUNE 1, NEPTUNE 2 NEPTUNE 2 Special If the mains power lead is dam- aged, 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 exten- sion leads must be watertight. When using an extension lead, check the minimum cross-sec- tions of the cable: Cable length

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 pow- er supply. Ensure that the volt- age 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 electri- cian and in compliance with IEC 60364 and the country-specific regulations. We recommend that the electri- cal connection to this appliance should incorporate – either a fault current circuit breaker, which cuts off the mains voltage if the fault current exceeds 30 mA for 30 ms, – or an earth resistance me- ter. Check that cleaning will not result in dangerous substanc- es (e.g. asbestos, oil) being washed off the object to be cleaned and harming the envi- ronment. 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 temper- ature are printed on the high- pressure hose. Store the cleaner where it will not be exposed to frost or use anti-freeze liquid! Never operate the cleaner with- out water. Even brief shortages of water result in severe dam- age 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 in- stalled, Type BA according to EN 60335-2-79. 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. Oper- ation by suction (for example from a rainwater vessel) is car- ried out without backflow pre- venter. 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 op- eration. Do not damage the mains pow- er 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 de- vised for use with cleansing agents that are supplied and recommended by the manufac- turer. 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 oper- ated at fuel stations or in other potentially hazardous areas, the machine may only be employed outside the hazard areas de- fined in the German „Technical Guidelines for Inflammable Flu- ids“ 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 con- nected to a flue gas stack, then local building regulations must be observed. We will be glad to provide tips for connection sys- tems, on request. CAUTION! Beware of hot water and steam discharge up to 150°C when operating in steam stage. CAUTION! Do not touch or cover the exhaust. Risk of burns and fire. Do not touch, cover or place hose or cord over the chimney. Danger for persons, risk of overheating and fire.7

Options / model variants Original instruction NEPTUNE 1, NEPTUNE 2 NEPTUNE 2 Special Electrical equipment CAUTION! Never spray electrical equip- ment with water: danger for per- sons, risk of short-circuiting. Switching on the cleaner may cause voltage fl uctuations. Voltage fluctuations should not occur if the impedance at the transfer point is less than 0.15 If in doubt ask your local elec- tricity supplier. Maintenance and repair CAUTION! Always remove the plug from the mains plug socket before clean- ing or carrying out maintenance work on the cleaner. Carry out only the maintenance operations described in the op- erating instructions. Use only original Nilfisk-ALTO spare parts. Do not make any technical mod- ifications to the high-pressure cleaner. Ensure that the machine is reg- ularly serviced by Authorised Nilfisk-ALTO dealers in accord- ance with the maintenace 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 ap- proved by the manufacturer! The mains power lead must not differ from the version specified by the manufacturer and may only be changed by an electri- cian. Please contact the Nilfisk-ALTO service department or an au- thorised specialist work-shop for all other maintenance or repair work! Testing The cleaner conforms to the German „Guidelines for Liq- uid Spray Jet Devices“. The high-pressure cleaner must be subjected to a safety examina- tion in accordance with the „Ac- cident Prevention Regulations for Working with Liquid Spray Jet Devices (BGV D15)“ as re- quired, but at least every 12 months, by an authorised in- spector. After all repairs or modifica- tions to electrical equipment, the protective conductor resist- ance, the insulation resistance and the leakage current must be measured. Furthermore, a visual inspection of the mains power lead, a voltage and cur- rent measurement and a func- tion test must be carried out. Our after-sales service techni- cians are at your disposal as au- thorised inspectors. The complete „Accident Preven- tion Regulations for Working with Liquid Spray Jet Devices“ are available from the Carl Hey- manns Verlag KG, Luxemburger Strasse 449, 50939 Cologne or from the appropriate associa- tion of employers’ liability insur- ances. The pressure-bearing parts of this high-pressure cleaner have been manufactured in accord- ance 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 pres- sure 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 protec- tion mechanism, a thermo-sen- sor 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. Warning

• Inhalation of aerosols can be hazardous to health.

• Where applicable use a de- vice in order to avoid or re- duce aerosols production, e.g., a shield covering the nozzle.

• For protection against aero- sols use a respiratory mask of class FFP 2 or higher.8

2.1 Purpose This high-pressure cleaner has

been designed for professional use. It can be used for clean- ing agricultural and construction equipment, stables, vehicles, rusty surfaces, etc. The cleaner has not been ap- proved for cleaning surfaces which comes into contact with food.

Chapter 5 describes the use of

the high-pressure cleaner for various cleaning jobs. Always use the cleaner as de- scribed in these operating in- structions. Any other use may damage the cleaner or the sur- face to be cleaned or may result in severe injury to persons. NEPTUNE 1 is for light profes- sional use only.

3 Before starting the cleaner

3.1 Setting up the cleaner Every fuel-burning appliance,

such as pressure washers, de- pends 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 Ker- osene or Diesel. Your Nilfisk-ALTO hot water pressure washer was thor- oughly 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 lev- el, your burner may require re- adjustment for proper perfor- mance 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 care- fully 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

1. Fill up detergent tank with

3.4 Fill up fuel tank

NOTE! At temperatures below 8° C, the fuel oil begins to solidify (paraffin precip- itation). This can lead to difficulties in starting the burner. Before the winter period either add a solidifica- tion point / flow improver (available from the fuel oil trade) to the fuel or use winter diesel fuel. With the machine cold: Fill fuel tank from a clean con- tainer with a fresh fuel, heating oil, DIN 51603-1 (without bio diesel) or Diesel EN 590 (Diesel with a bio diesel content up to 7%). Diesel according to EN 590 (up to 7% bio diesel) can be used with the following restrictions: Maximum storage time in high pressure cleaner diesel tank: 1 month. Diesel stored externally for more than 6 months is not allowed to be filled into Nilfisk-ALTO high pressure cleaners. Diesel EN 590 is not recom- mended for use in HPW's at an ambient temperature below 0°C. Diesel EN 590 from an open container must not be used. The fuel must be free from con- tamination. Tank capacity see chapter 9.4 Technical data. Be careful not to damage the fuel tank filter to avoid dirt entering in the tank

3.5 Connecting the high

1. Put the quick connector of

the high pressure hose onto the nipple on the cleaner.

3.6 Connecting the water

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

NOTE! See chapter 9.4 Technical Data for required quantity of water and water pressure. 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 nomi- nal diameter of min. 3/4" (19 mm).11

3.7 Electrical connection

Before connecting devices with voltage changeover

: Check that the pre-selected voltage on the machine corresponds with the voltage of the electrical instal- lation. Otherwise the electrical devices of the machine can be destroyed. CAUTION! When using cable reels:

1. Due to the risk of overheat-

ing and fire, always unwind the power supply cord fully. The cleaner may only be con- nected to a correctly installed electrical installation.

4.4 Using cleaning agents

For safety reasons, never tie back or wedge open the trigger of the spray gun in open position during operation. The trigger must be free to close when released, thus interrupting the flow of the water. CAUTION! Never allow cleaning agent to dry on the surface to be cleaned. The surface may be damaged. For special applications (e.g. disinfec- tion) the exact detergent concentration has to be determined by measuring cup. For water throughput of the machine see

chapter 9.4 technical data.

Effi cient high pressure cleaning is achieved by following a few guidelines, combined with your own personal experience of specifi c cleaning tasks. Accessories and detergents, when correctly chosen, can increase the effi ciency of your pressure washer. Here is some basic information about cleaning.

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. 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.

5.1.2 Detergent and Foam

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°C. Oils, traffi c fi lm around 70°C, and grease can be cleaned at 80°C - 90° C.

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 fl ow. Pressure levels of around 100 bar may be suffi cient for vehicle cleaning (in association with hot water). Higher fl ow levels give the possibility to rinse and fl ush away large amounts of dirt easily.

5.2 Some typical cleaning

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 fl ush away large quantities of dirt, change to low

pressure mode and use the higher fl ow 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 un- derchassis 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 diffi cult to reach places.

3. Clean fragile areas such as motors, rubber at lower

pressure levels to avoid damage.15

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 diffi cult 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 Metallic equipment Foam injectors Standard lance Curved lances Tank cleaning head Detergents Intensive J25 Multi Combi Aktive Alkafoam Disinfectant DES 3000

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.

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 fl ush away loose dirt and rinse surfaces.

3. Apply DES 3000 disinfectant once the surfaces are

perfectly clean. Areas covered by amounts of loose dirt, such as animal remains in slaughterhouses, can be cleaned by using high water fl ow to fl ush 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-

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 asso- ciation with accessories and detergents. Each cleaning task is different. Please consult your local dealer or Nilfi sk-ALTO representative in order to discuss the best solution for your own cleaning tasks.16
