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.

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

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 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

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.

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

10

o

in any direction.

3.3 Fill up detergent tank

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

5 Applications and methods

5.1 Techniques

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.

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.

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.

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.

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 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.

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-

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 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.
