2 Safety precautions and working techniques
Before starting up your machine for the first time, this instruction manual must be read through
carefully. Save the instructions for later use.
WARNING!
• Inhalation of aerosols can be hazardous to health.
Where applicable use a device in order to avoid or re-
duce aerosols production, e.g., a shield covering the
nozzle. For protection against aerosols use a respira-
tory mask of class FFP 2 or higher.
• The high water pressure generated by the machine
and the power connection are particular sources of
danger.
• Children should be supervised to ensure that they do
not play with the machine.
• Before starting up your machine please check it care-
fully for any defects. If you find any, do not start up
your machine, contact your Gerni distributor. The in-
sulation of the electric cable should be faultless and
without any cracks. If the electric cable is damaged,
an authorized Gerni distributor should replace it.
• The operator and anyone in the immediate vicinity of
the site of cleaning should take action to protect them-
selves from being struck by debris dislodged during
operation.
• Always unplug the power plug before cleaning or

6Original Instructions
Transporting the high pressure washer
• When transporting the machine in or on a vehicle, it
must be secured, e.g. with straps, so that it cannot slip
or tip over.
• Gerni recommends that the machine is positioned
horizontally on the backside, when transported in or
on a vehicle.
Detergents
• This machine has been designed for use with clean-
ing agents supplied or recommended by Gerni. The
use of other cleaning agents or chemicals may ad-
versely affect the function of the machine.
Before starting the work
Inspecting the machine
• Do not use the machine if a supply cord or important
parts of the machine are damaged, e.g., safety de-
vice, high pressure hose, and spray handle and spray
attachments.
• The trigger of the spray handle must move easily and
automatically return to its starting position when re-
leased.
• Always keep high pressure hose and spray attach-
ment in good condition (clean, moving easily) and cor-
rectly assembled.
Electrical connection
WARNING!
Minimize the risk for electrical shock:
• Voltage and frequency of the machine (see rating
plate) must match the voltage of and frequency of the
mains supply.
• Only connect the machine to electrical installation
made by a certified electrician and comply with IEC
60364-1.
• It is recommended that the electrical supply to the
machine should include a residual current device that
will interrupt the supply if the leakage current to earth


7Original Instructions
exceeds 30 mA for 30 ms.
• Inadequate extension cables can be dangerous. If an
extension cable is used, it should be heavy duty and
suitable for outdoor use, and the connection has to be
kept dry and off the ground
• Gerni recommends use of an extension cable drum
when cable extension is needed which keeps the
socket at least 60 mm above the ground.
• Cables on extension cable drums should always be
completely unwound to prevent overheating. Exten-
sion cables must comply with the below-mentioned re-
quirements for length and cable dimensions:
1.0 mm² Max. 12.5 m
1.5 mm² Max. 20.0 m
2.5 mm² Max. 30.0 m
• If the electric cable is damaged, it must be replaced
by an authorized Gerni distributor or similar qualified
person in order to avoid a hazard.
Water connection
• This high pressure washer is only allowed to be con-
nected with the drinking water mains, when an appro-
priate backflow preventer has been installed, Type BA
according to EN 60335-2-79.
• The backflow preventer can be ordered under number
106411177.
• As soon as drinking water has flown through the back-
flow preventer, it is no longer regarded as drinking
water.
• Operation by suction (e.g. a rainwater vessel) is car-
ried out without a backflow preventer – see “Connec-
ting to a pressureless water supply”.
IMPORTANT !
• Only use water without any impurities.
• If there is a risk of running sands in the inlet water
(i.e. from your own well), an additional filter should be
mounted.
