1 Important safety instructions
Symbols used to mark
instructions
Before using the
high-pressure
cleaner, be sure
to also read the
enclosed operat-
ing instructions
and keep them within reach at
all times.
For your own safety
The high-pressure cleaner should
only be used by authorized persons who have been instructed
in its use.
Although extremely easy to
operate, children should not be
allowed to use the cleaner.
General
Use of the high-pressure cleaner
is subject to the applicable local
regulations.
Besides the operating instructions and the binding accident
prevention regulations valid in
the country of use, observe recognized regulations for safety
and proper use.
Do not use any unsafe work
techniques.
Transport
Transport of the high-pressure
cleaner is easy on its large
wheels.
For safe transport in and on vehicles 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 fitted with a suitable 3-phase
plug with ground, by a qualified
electrician.
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.
Please observe the regulations
and provisions applicable in your
area. Before putting the highpressure cleaner into service,
carry out a visual check of all
the major components.
Safety instructions
in these operating
instructions which
must be observed
to prevent risks
to persons are marked with this
danger symbol.
This symbol is used to
mark safety instruc-
tions that must be
observed to prevent
damage to the machine
and its performance.
This indicates tips
and instructions
to simplify work
a n d to ensure safe opera-
tion.
Operations marked

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
firmly 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!
Store the cleaner where
it will not be exposed to
frost!
Never operate the cleaner without water. Even brief shortages
of water result in severe damage
to the pump seals.
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:
Cord length

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 fire.
Use clean fuel only, free of moisture and contamination. Contact
your dealer for fuel source and
type recommendations.
This machine can be used
with Bio-Diesel (DIN 51606).
However, our experience has
shown that the fuel quality is
often outside the recognized
standards. An organic product
like Bio-Diesel can be affected by
long-term storage (e.g. over the
winter), extreme temperatures,
or improper transportation. When
the condition of the fuel is outside
the standards, trouble may occur
which cannot be covered by the
Warranty.
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.
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 flue gas stack, then
local building regulations must be
observed. We will be glad to provide tips for connection systems,
on request.
CAUTION!
Do not touch or cover the exhaust. Risk of burns and fire.
Electrical equipment
CAUTION!
Never spray electrical equipment with water: risk of electtrical shock and short-circuit.
The cleaner may only be connected to a correctly installed
plug socket.
Switching on the cleaner may
cause voltage fluctuations.
Voltage fluctuations should not
occur if the impedance at the
transfer point is less than 0.15:
If in doubt ask your local electricity supplier.

Maintenance and repair
CAUTION!
Always remove the plug from the
power supply before cleaning or
carrying out maintenance work
on the cleaner.
Carry out only the maintenance
operations described in the
operating instructions. Use only
original Gerni spare parts.
Do not make any technical
modifications to the high-pressure cleaner.
Ensure that the machine is regularly serviced by authorized Gerni
dealers in accordance with the
maintenace plan. Failure to do
so will void the warranty.
CAUTION!
High-pressure hoses, fittings
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 specified by the
manufacturer and may only be
changed by an electrician.
Please contact your local authorized Gerni 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 lead, 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.
Unloader valve
Pump pressure is reduced by
means of an "unloader 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.

5 Applications and methods
Efficient high pressure cleaning is achieved by following a few guidelines, combined with your own personal experience of specific cleaning tasks. Accessories and detergents, when correctly chosen, can
increase the efficiency 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 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.
5.1 Techniques
4.5 Using cleaning agents
1. Select desired detergent (A)
or (B) and amount by turning
the knob to desired percentage.
2. Spray the object to be
cleaned.
3. Allow the cleaning agent to
work, depending on the degree of soiling. Then rinse off
with high pressure.
4.4 Pressure regulation
(VarioPress Gun)

1. Turn the twist grip on the
spray unit:

The percentage shown in the
illustration are only approximate
data.
For special applications such as
disinfection, the exact detergent
concentration has to be determined by using a graduated
measuring container. For water
outlet volume of the machine see
chapter 9.3 technical data.
,
CAUTION!
Never allow cleaning agent
to dry on the surface to be
cleaned. The surface may be
damaged.

NEPTUNE 5 / 7
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 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.
5.1.3 Temperature
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 traffic film around 70°C (158°F), and grease can be cleaned
at 80°-90°C (176-194°F).
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 may also damage
surfaces. The cleaning effect also depends upon water flow. Pressure levels of around 100 bar (1450 psi) may be sufficient for vehicle
cleaning (in association with hot water) and higher flow levels give
the ability to rinse and flush away large amounts of dirt easily.

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 difficult 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 flush 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 flow to flush 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 damages 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 sandblasting.
3. Spray the surfaces to be treated with the mix of water
and sand. Rust, paint etc will be stripped off.
