Symbols Before starting
up your high-
pressure washer
for the first time,
this instruction
manual must be
read through carefully. Save the
instructions for later use.
Safety instructions
marked with this
symbol must be
observed to
prevent danger
to persons.
This symbol is used
to mark safety
instructions
that must be
observed to prevent
damage to the machine and its
performance.
This symbol
indicates tips
and instructions to
simplify work and to
ensure a safe operation.
,
Before using the high-pressure
washer, be sure to also read the
enclosed operating instructions
and keep them within reach at
all times.
The high-pressure washer
may only be used by persons
instructed in its use and
who have been expressly
authorised to do so.
General
Use of the high-pressure
washer is subject to the
applicable local regulations.
In addition to the operating
instructions and the binding
accident prevention regulations
in the country of use, the
generally recognised rules
for safe working must also be
observed.
Any method of use endangering
the safety of persons or
equipment is forbidden.
Before use
Before use, check that the high-
pressure cleaner is in a safe
and proper condition.
Operate the pressure washer
only in an upright position!
Important notes:
Do not connect the pressure
washer directly to the public
drinking water mains (observe
DIN 1988 and EN 1717).
A connection is permitted,
however:
• briefly to a pipe interrupter
with moving section
• with a free outlet
Water may also be drawn from
an open container or from
a well or surface water not
intended for the drinking water
supply. Please use suction set
for this. Ensure that neither dirty
water nor liquids containing
solvents are sucked in.
Please observe the regulations
and provisions applicable in
your country. Before putting
the high-pressure washer into
service, carry out a visual check
of all the major components.
High-pressure jets can be
dangerous if misused. The
jet must not be directed at
persons, animals, live electrical
equipment or the pressure
washer itself.
During operation of the washer,
recoil forces are produced at
the spray lance and, when
the lance is held at an angle,
a torque is also created. The
lance must therefore be held
firmly in both hands.
Risk of injury!
Do not direct the jet towards
yourself or towards other
persons in order to clean
clothes or footwear.
Do not use the washer 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 round jet. Hold the nozzle
at a distance of at least 15 cm
when cleaning with the high-
pressure flat jet.
Although extremely easy to
operate, children should not
be allowed to use the pressure
washer.
Do not use the high-pressure
hose for lifting loads.
Do not continue to use the
washer if the quick coupling
or high-pressure hose is
damaged.
Never use the machine in areas
where there is danger of fire
or explosion. When using the
pressure washer, stand at least
1 m from buildings, etc.
Ensure an adequate air
circulation. Do not cover
the washer or operate it in
inadequately ventilated rooms!
The exhaust fumes are
dangerous!
Store the pressure washer
where it will not be exposed to
frost!
Never operate the pressure
washer without water. Even
brief shortages of water result
in severe damage to the pump
seals.
Maintenace and repair
CAUTION!
Before cleaning and servicing
the high pressure washer,
always remove the ignition
plug cable first.
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 washer.
CAUTION!
High pressure hoses, fittings
and couplings are important
for the safety of the washer.
Use only high pressure parts
approved by the manufacturer!
CAUTION!
Failure to observe these
instructions can endanger your
safety.
Please contact the Gerni
service department or an
authorised specialist work-shop
for all other maintenance or
repair work!
Testing
The machine satisfies IEC/EN
60335-2-79 standards.
The high pressure washer
should be examined as needed
or at least once a year by a
technician to make sure that it
is fail-safe.
Our service technicians are at
your disposal for assistance
and advice.
Safety device
The high pressure pump is
equipped with a safety valve
that redirects the by-pass
pressure back to the suction
side of the pump.
The safety device is set and
sealed at the factory and must
not be adjusted.
