1 Important safety instructions

Symbols used to mark

instructions

Before using the

high-pressure-

cleaner, be sure to

also read the en-

closed operating in-

structions 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 ex-

plicitly commisioned 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

Warning

Ensure that any exhaust emis-

sions are not in the vicinity of air

intakes.

This machine shall only be used

with cleaning chemicals supplied

or recommended by Nilﬁ sk-ALTO.

The use of other cleaning chemi-

cals may adversely affect the

safety of the machine.

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 recog-

nized regulations for safety and

proper use.

Do not use any unsafe work

techniques.

Do not tie the trigger handle

open.

Transport

Transport of the high-pressure

cleaner is easy on its large

wheels.

For safe transport in and on ve-

hicles 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°C

(32°F), 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 ﬁ tted with a suitable 3-phase

plug with ground, by a qualiﬁ ed

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 cor-

responds to the voltage of the

power supply.

We strongly recommend that the

power supply to the high pres-

sure cleaner be connected via a

residual current circuit breaker.

This device stops the supply of

electricity if the leakage current

to the ground exceeds 30 mA 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,

Safety instruc-

tions in these op-

erating 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 per-

formance.

This indicates

tips and instruc-

tions to simplify

work and to en-

sure safe operation.

Operations marked

with this symbol

should only be car-

ried out by Nilfisk-

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 electri-

cal equipment or the cleaner

itself.

Wear appropriate protective

clothing and eye protection.

Do not direct the jet towards

yourself or towards other per-

sons 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 cre-

ated. The gunvalve and spray

lancemust therefore be held

ﬁ rmly in both hands.

Do not use the cleaner when

other people without protec-

tive 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 work-

ing 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 oper-

ate it in inadequately ventilated

rooms!

Store the cleaner where

it will not be exposed to

frost or use antifreeze

liquid!

Never operate the cleaner with-

out water. Even brief shortages

of water result in severe damage

to the pump seals.

Water connection

This high pressure

washer is only al-

lowed to be con-

nected with the

drinking water

mains, when an appropriate

backflow preventer has been

installed, Type BA according

to EN 1717. If the back ﬂ ow

preventer hasn’t been supplied,

one can be purchased from your

dealer. The length of the hose

between the backﬂ ow preventer

and the high pressure washer

must be at least 12 metres (min

diameter 3/4 inch) to absorb pos-

sible pressure peaks. Operation

by suction (for example from

a rainwater vessel) is carried

out without backﬂ ow 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 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 over-

heating.

Connectors and couplings of

extension cords must be water-

tight.

Extension cords are not recom-

mended, however if necessaray

refer to the following recommen-

dations:

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 ﬁ re.

Use clean fuel only, free of mois-

ture and contamination. Contact

your dealer for fuel source and

type recommendations.

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 deﬁ ned in the

German „Technical Guidelines

for Inﬂ ammable Fluids“ applica-

ble 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 regu-

lations 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 ﬂ ue gas stack, then local

building regulations must be ob-

served. We will be glad to provide

tips for connection systems, on

request.

CAUTION!

Beware of hot water and

steam discharge up to

150

0

C when operating in

steam stage.

CAUTION!

Do not touch or cover the

exhaust. Risk of burns

hose or cord over the chimney.

Danger for persons, risk of

overheating and ﬁ re.

Electrical equipment

CAUTION!

Never spray electrical equip-

ment with water: risk of elect-

trical shock and short-circuit.

The cleaner may only be con-

nected to a correctly installed

plug socket.

Switching on the cleaner may

cause voltage ﬂ uctuations.

Voltage ﬂ uctuations should not

occur if the impedance at the

transfer point is less than 0.15Ω.

If in doubt ask your local electric-

ity supplier.

Maintenance and repair

CAUTION!

Always remove the plug from

the power supply before clea-

ning or carrying out mainte-

nance work on the cleaner.

Carry out only the maintenance

operations described in the oper-

ating instructions. Use only origi-

nal Nilﬁ sk-ALTO spare parts.

Do not make any technical modi-

fications to the high-pressure

cleaner.

Ensure that the machine is regu-

larly serviced by authorized Nil-

ﬁ sk-ALTO dealers in accordance

with the maintenace plan. Failure

to do so will void the warranty.

CAUTION!

High-pressure hoses, ﬁ ttings

and couplings are important

for the safety of the cleaner.

Use only high-pressure parts

approved by the manufac-

turer!

The power cord must not differ

from the version speciﬁ ed by the

manufacturer and may only be

changed by an electrician.

Please contact your local author-

ized Nilﬁ sk-ALTO equipment dis-

tributor for all other maintenance

or repair needs!

Testing

The cleaner conforms to the Ger-

man „Guidelines for Liquid Spray

Jet Devices“. The high-pressure

cleaner must be subjected to a

safety examination in accord-

ance with the „Accident Preven-

tion Regulations for Working

with Liquid Spray Jet Devices“

as required, but at least every

12 months, by an authorised

inspector.

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 cord, 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 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.

Bypass valve

The pressure is reduced by

means of a "bypass 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.

2 Description

2.1 Purpose

This high-pressure cleaner has

been designed for professional

use. It can be used for cleaning

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.

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 ‘Nat-

ural gas’, Propane 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 120m

(390 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 per-

formance and best fuel econ-

omy. Contact your Dealer or

Nilfisk-ALTO for assistance.

3.2 Set the brake

Before using the cleaner for 1.

the first time, check it care-

fully to detect any faults or

damage.

Run the machine only when 2.

it is in perfect condition.

Set the brake.3.

The slope of which the high 4.

pressure cleaner is placed

must not exceed more than

10° in any direction.

See fold-out page at front of these

operating instructions.

into the fuel tank.

Bio-Diesel can be used, see

notes in chapter 1).

The fuel must be free from con-

tamination.

Tank capacity see chapter 9.4

Technical data.

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.

ing and fire, always unwind

the power supply cord fully.

The cleaner may only be con-

nected to a correctly installed

electrical installation.

1. Observe safety instructions in

chapter 1.

2. Put the plug into the electrical

socket.

In the case of poor water quality

(sand, etc.), we recommend that a

fine water filter is fitted in the water

inlet.

NOTE!

See chapter 9.4 Technical Data for

required quantity of water and water

pressure.

In order to comply with national

regulations and those of the water

supply companies, it must be

ensured that water cannot ﬂ ow

back if the pressure in the water

mains falls below atmospheric

pressure.

We recommend the use of a textile-

reinforced water hose with a nomi-

nal diameter of min. 3/4" (19 mm).

5 Applications and methods

Efﬁ cient high pressure cleaning is achieved by following a few guide-

lines, combined with your own personal experience of speciﬁ c clean-

ing 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 Techniques

4.5 Using cleaning agents

1. Set the desired concentra-

tion of cleansing agent at the

cleansing agent dosing facil-

ity.

2. Spray the object to be

cleaned.

3. Allow the cleaning agent to

work, depending on the de-

gree of soiling. Then rinse off

with the high pressure spray

jet.

4.4 Pressure regulation

(VarioPress Gun)

1)

,

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 ﬂ ow of the water.

1. Turn the twist grip on the

spray unit:

CAUTION!

Never allow cleaning agent to dry

on the surface to be cleaned. The

surface may be damaged.

NEPTUNE 4 FA

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 via use of foam or simple alkaline detergent. Let

the product lie on the dirty surfaces for around 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 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 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°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. 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 removed 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 dam-

ages 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.
