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 explicitly commisioned with the
task of operating it.
• only be operated under supervision.
• not be used by children.
• not be used by mentally or
physically disabled persons
Warning
• Ensure that any exhaust
emissions are not in the vicinity of air intakes.
• This machine shall only be
used with cleaning chemicals
supplied or recommended
by Gerni. The use of other
cleaning chemicals may
adversely affect the safety of
the machine.
• Risk of explosion – Do not
use the cleaner to spray with
fl ammable liquids.
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.
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 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 fi tted
with a suitable 3-phase plug with
ground, by a qualifi ed 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.
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!
Store the cleaner where
it will not be exposed to
frost or use antifreeze
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:

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 moisture 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“ 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.
CAUTION!
Beware of hot water and
steam discharge up to
1500C when operating in
steam stage.

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 fl uctuations.
Voltage fl uctuations 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!
The cleaner must be disconnected from its power source
during cleaning of the machine, maintenance, when replacing parts or converting the
machine to another function.
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, 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 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 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.
2 Description

chine by hand from the pallet.
Due to the weight this work
should be done by at least
three persons.
CAUTION!
Do not hold the plastic tank to lift
the machine as it could become
detached from the frame.
The best places to hold the ma-
chine are
– on the handle
– on the frame between the front
wheels and the guide rollers.
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.
Your Gerni hot water pressure
washer was thoroughly 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 readjustment for proper performance and best fuel economy.
Contact your Dealer or Gerni for
assistance.

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 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
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 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.
5 Applications and methods
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 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.

5.2.3 Buildings and Equipment
These are merely several examples of cleaning tasks that can be solved by a pressure washer in association with accessories and detergents. Each cleaning task is different. Please consult your local dealer
or Gerni representative in order to discuss the best solution for your own cleaning tasks.
Task Accessories Method
General surfaces
Metallic equipment
Foam injectors Standard lance
Curved lances
Tank cleaning
head
Detergents
Intensive
J25 Multi
Combi Active
Alkafoam
Disinfectant
DES 3000
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 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.
