1 Important safety instructions
Before use, check that the highpressure 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 30 mA for
30 ms or it has an ground tester
circuit.

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
lancemust therefore be held
fi rmly 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!

Options / model variants
Store the cleaner where
it will not be exposed to
or use antifreeze
frost
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 water
mains, 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 12 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 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 necessaray
refer to the following recommendations:

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“ 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 fl ue gas stack, then
local building regulations must be
observed. We will be glad to provide tips for connection systems,
on request.

operations described in the operating instructions. Use only original Nilfi sk-ALTO spare parts.
Do not make any technical modifications to the high-pressure
cleaner.
Ensure that the machine is regularly serviced by authorized Nilfi 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 manufacturer!
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 authorized Nilfi sk-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 cord, a voltage and current
measurement and a function test
must be carried out. Our aftersales 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.
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.

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.

5 Applications and methods
NEPTUNE 5 SB FA
5.1 Techniques
5.1.1 Soaking
5.1.2 Detergent and Foam
5.1.3 Temperature
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 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.
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.
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°C (140°F).
Oils and traffi c fi lm around 70°C (158°F), and grease can be cleaned
at 80°-90°C (176-194°F).
5.1.4 Mechanical Effect
5.1.5 High Water Flow or
High Pressure
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.
High pressure is not always the best solution and may also damage
surfaces. The cleaning effect also depends upon water fl ow. Pressure levels of around 100 bar (1450 psi) may be suffi cient for vehicle
cleaning (in association with hot water) and higher fl ow levels give
the ability to rinse and fl ush away large amounts of dirt easily.
