Symbols used to mark
instructions

Before using the 

h i g h - p r e s s u r e 
cleaner, be sure 
to also read the 

enclosed operat-

ing instructions and 

keep them within reach at all 
times.

Safety instructions in 

these operating in-

structions which 

must be observed 

to prevent risks 

to persons are 

marked with this danger sym-
bol.

This symbol is used 

to mark safety in-

structions that must 

be observed to pre-

vent damage to the ma-

chine and its performance.

This indicates 
tips and in-

structions to 

simplify work and 

to 

en- sure safe operation.

1 Important safety instructions

For your own safety

The high-pressure cleaner may 
only be used by persons in-
structed in its use and who have 
been expressly authorised to do 
so.

Although extremely easy to op-
erate, children should not be al-
lowed to use the cleaner.

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 rec-
ognised 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 ve-
hicles we recommend to prevent 
the equipment from sliding and 
tilting by fixing it with belts.

Transport (when tilted):  
– do not tilt the machine on the 

front with the water connec-
tions.  

– remove suction hose from 

the detergent tank and close 
tank filler with the cap pro-
vided with the machine.

– before putting the cleaner 

into operation: pay attention 
to allow the pump oil to run 
back into the pump housing. 
Check oil level, top up if nec-
essary.

For transport at temperatures 
around or below 0°C, 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 earth conductor, by an 
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 mains power lead 
is in a safe condition. (risk of 
electric shock if damaged!).

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 corre-
sponds to the voltage of the lo-
cal mains 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 earth exceeds 30 mA for 30 
ms or it has an earth tester cir-
cuit.

Operate the cleaner only in an 
upright position!

Please observe the regulations 
and provisions applicable in 
your country. Before putting the 
high-pressure cleaner into serv-
ice, 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 per-
sons, animals, live electrical 
equipment or the cleaner itself.
Wear appropriate protective 
clothing and eye protectors.

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 
spraying device and, when the 
spray lance is held at an angle, 
a torque is also created. The 
spraying  device must therefore 
be held firmly 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 re-
sult 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 tempera-

ture are printed on the high-
pressure hose.

Do not continue to use the 
cleaner if the mains power lead 
or high-pressure hose is dam-
aged.

Ensure adequate air circula-
tion. Do not cover the cleaner or 
operate it in inadequately venti-
lated rooms!

Store the cleaner where 
it will not be exposed to 
frost!

Never operate the cleaner with-
out water. Even brief shortages 
of water result in severe dam-
age to the pump seals.

Operation

CAUTION!

Unsuitable extension leads can 
represent a source of danger. 
Always unwind cord from the 
reels completely to prevent the 
power cord overheating.

Plugs and connectors of mains 
power leads must be at least 
splash water-proof. 

When using an extension cord, 
check the minimum cross-sec-
tions of the cable:

Cable length

m

Cross section

<16 A

<25 A

up to 20 m

ø1.5

mm²

ø2.5

mm²

20 to 50 m

ø2.5

Do not damage the mains pow-
er 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).

Electrical equipment

CAUTION!

Never spray electrical equip-
ment with water: danger for per-

sons, risk of short-circuiting.

The cleaner may only be con-
nected 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 elec-
tricity supplier.

Maintenance and repair

CAUTION!

Always remove the plug from the 
mains plug socket before clean-
ing or carrying out maintenance 
work on the cleaner.

Carry out only the maintenance 
operations described in the op-
erating instructions. Use only 
original Gerni spare parts.
Do not make any technical mod-
ifications to the high-pressure 
cleaner.

Ensure that the machine is reg-
ularly serviced by Authorised 
Gerni dealers in accordance 
with the maintenace plan. Fail-
ure to do so will invalidate the 
warranty.

CAUTION!

High-pressure hoses, fittings 
and couplings are important for 
the safety of the cleaner. Use 
only high-pressure parts ap-
proved by the manufacturer!

The mains power lead must not 
differ from the version specified 
by the manufacturer and may 
only be changed by an electri-
cian.
Please contact the Gerni serv-
ice department or an authorised 
specialist work-shop for all other 
maintenance or repair work!

5 Applications and methods

Efficient high pressure cleaning is achieved by following a few guide-
lines, combined with your own personal experience of specific clean-
ing 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 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 Techniques

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, traffic 
film 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 
flow. Pressure levels of around 100 bar may be sufficient for vehicle 
cleaning (in association with hot water). Higher flow levels give the 
possibility to rinse and flush 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 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.

connection.

2. Remove the filter and rinse it. 

Replace damaged filter. Re-
place damaged filter.

7.2.2 Checking the pump oil

level

1. Check whether the oil level 

is between the minimum and 
maximum marks. If neces-
sary, add oil (see chapter 9.4 
for type of oil).

low the cleaner to become 
warm.

2. Remove cover.
3. Loosen the hose clamp (A).
4. Remove the hose from the 

hose nipple. Allow the oil to 
drain into a suitable contain-
er (min. 1 l capacity) and dis-
pose of oil in compliance with 
regulations.

5. Attach the hose and secure it 

using the hose clamp. 

6. Fill pump with fresh oil until 

it appears between the MIN-
MAX marks.
Oil grade and capacity see 
chapter ‘9.4 Technical Data’.
Check that no oil remains in 
the expansion tank (Do not

8 Troubleshooting

Fault

Cause

Remedy

Pressure drop

>

Air in the system

Vent the system by 
operating the spray gun 
several times at short 
intervals. If necessary, 
operate the cleaner for a 
short time without the high-
pressure hose connected.

>

High pressure nozzle blocked 
worn

Clean/replace the high 
pressure nozzle

>

Pressure control on the spray 
pipe is not set correctly

Set the required working 
pressure

>

Detergent tank empty

Top up detergent tank or 
set detergent metering to 
“0”

Pressure fluctuations

>

Pump draws in air (only 
possible in suction mode)

Check that the suction set 
is air-tight

>

Lack of water

Open water tap

>

Water inlet hose is too long 
or its cross-section too small

Use specified water inlet 
hose

>

Lack of water caused by 
blocked water filter

Clean the water filter in the 
water connection (never 
work without water filter)

>

Lack of water because max. 
permissible suction height 
has not been heeded

See instructions

The motor does not start when 
the cleaner is switched on

>

The plug is not inserted 
properly, i.e. there is no 
current

Check the plug, lead and 
switch and if necessary 
have them replaced by a 
trained electrician

>

The mains fuse is switched 
off

Switch on the mains fuse

When the cleaner is switched 
on the motor buzzes without 
starting

>

The mains voltage is too low 
or there is a phase failure.

Have the electrical 
connection checked

>

The pump is blocked or 
frozen

Contact the Gerni customer 
service

>

Incorrect cross-section or 
length of the extension lead

Use lead with correct cross 
section or length

The motor switches off

>

The overload protection 
has been activated due to 
overheating or overloading of 
the motor

Check that the mains 
voltage and the cleaner 
voltage are the same. 
Switch off the cleaner and 
allow it to cool for at least 3 
minutes

>

High-pressure nozzle is dirty

Change the high-pressure 
nozzle
