1 Safety Precautions and Warnings
Before starting up your high
pressure hot water washer for
the fi rst time, this instruction
manual must be read through
carefully. Save the instructions
for later use.
Only let instructed people operate the machine.
General
When using the high pressure
hot water washer all existing
national regulations must be
observed. Beyond the instruction manual and the current
national legal regulations for
prevention of accidents, also
the approved rules for safe
working must be observed.
Any method of use endangering
the safety of persons or equipment is forbidden.
Before use
Before starting up your high
pressure hot water washer
check that it is in a regular
condition. Electric plugs and
couplings must be watertight.
Check the electric cables at
regular intervals for damage
and wear. Only use the high
pressure hot water washer if the
electric cable is all right (damaged electric cables can cause
electric shock!)
Important instructions
Connection to public drinking
water supply must be performed in accordance with the
applicable regulations in your
country.
IMPORTANT: Only use water
without impurities!
Before each use of your high
pressure hot water washer
check the most important visual
parts.
High pressure jets can be
dangerous if misused. Never
direct the water jet towards people, pets, electric wiring, or the
machine itself.
Spray handle and lance are affected by a thrust during operation - therefore always hold the
spray lance fi rmly with both
hands.
Never try to clean clothes or
footwear on yourself or other
persons.
Operator and anyone in immediate vicinity of the site of cleaning should take action to protect
himself from being struck by
debris dislodged during operation.
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 sensitive surfaces
made of rubber, fabrics or the
like with the zero nozzle. With
the fl at jet nozzle keep a distance of at least 15 cm to the
surface to be cleaned.
Never let children operate the
machine.
Do not use the machine if the
electric cable or the high pressure hose are damaged.
Do not cover the machine during operation or use it in a room
without adequate ventilation !
If any of the machines overload protection devices trips
(machine stops unintended),
release the trigger of the spray
handle. Lock the spray handle
with locking device and turn
the start/stop switch to position
„OFF“.
Refer to section "7 Trouble
Shooting".
The machine must be placed in
a room where it is not exposed
to frost.
Never start the cleaner without
water supply. Even a short water defi ciency can damage the
sleeves of the pump.
Operation
Avoid damage to the electric
cables such as squeezing, pulling, knots etc. and keep them
away from sharp or hot objects.
Avoid damage to the high pressure hose such as running over
by vehicles, squeezing, pulling,
knots/kinks etc. and keep it
away from oil and sharp or hot
objects, as such may cause the
hose to burst.
4
The cleaner can be used in
zones classifi ed as ZONE 2.
Important! Never use the
machine in an environment
where there could be a danger of explosion (according to
EN-50014).
Important! When the system
has been in operation and
thereafter stopped, there might
still be a working pressure in
the pipeline and high pressure
hoses. Therefore you should
pay special attention to the following:
• Never dismount the high
pressure hose from the
machine during operation.
Disconnect the machine,
close the shut-off cock and
relieve the high pressure
hose of pressure prior to
dismounting.
• Never dismount the high
pressure hose from the outlet point before it has been
securely closed and the high
pressure hose has been
relieved of pressure.
• Prior to any service interference in the machine it
should be disconnected and
the system relieved of pressure by activating the trigger
of the spray handle.

nozzles and couplings are
important for the safety when
operating the machine. Only
use the high pressure hoses,
nozzles and couplings pre-
scribed by Nilfi sk-ALTO!
For major repairs, please contact your nearest Nilfi sk-ALTO
service organisation.
Mains power connection
This product is intended for
stationary installation only
and is supplied without a
power cord! Only let an authorized electrician connect
the machine to the mains
supply !
The following points must be
observed:
• Check that the voltage
stated on the data plate
corresponds to your mains
voltage.
• Make sure that the power
cord contains the right
number of wires (including
ground wire) and that each
wire has the right dimensions to carry the load (amperage) stated on the data
plate of the machine.
• Make sure that the installation (cables, connection
points and fuses) is correctly
dimensioned for the load of
the machine - refer to the
data plate of the machine.
If not required by local legislation, we strongly recommend you to connect the
machine to a power source
with a Residual Current Device (RCD) which will disconnect the power supply if the
leakage current exceeds 30
mA for 20 milli seconds !
See section "3.5 Mains power
connection" for further instruc-
tions.
Only let a qualifi ed electrician
maintain the electric installation.
Safety Devices
Safety Valve
The pressure side of the high
pressure pump is fi tted with a
safety valve. This valve leads
the water back to the suction
side of the pump when the
spray handle is closed or if a
nozzle is blocked.
The safety valve is adjusted
and sealed by the producer.
THIS ADJUSTMENT MUST
NOT BE CHANGED !
Machine protection
The machine features an overcurrent protection and built-in
thermal protection of the motor.
In the event of increased power
consumption (maloperation)
and in the event of excessive
motor temperature (obstructed
ventilation etc.), the entire
machine will automatically be
disconnected from the mains
supply.
Short circuit protection
The machine is equipped with
a short-circuit protection. In the
event of short-circuits in the
