Do not tie the trigger handle
open.
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 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 highpressure hose and the spray
gun. Do not operate the appliance if any of these parts are
damaged.

NEPTUNE 2 Special
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 lengthmCross section
<16 A <25 A
up to 20 m
20 to 50 m
ø1.5mm² ø2.5mm²
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 30 mA for
30 ms,
– or an earth resistance me-
ter.
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.
1)
Options / model variants
Original instruction
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 highpressure hose.
Store the cleaner where
it will not be exposed to
frost or use anti-freeze
liquid!
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 watermains, 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.

Testing
The cleaner conforms to the
German „Guidelines for Liquid
Spray Jet Devices“. The highpressure cleaner must be subjected to a safety examination
in accordance with the „Accident Prevention Regulations for
Working with Liquid Spray Jet
Devices (BGV D15)“ 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 builtin 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.

NOTE!
At temperatures below 8° C, 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.

5 Applications and methods
NEPTUNE 1, NEPTUNE 2
NEPTUNE 2 Special
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.
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°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.
