Original Instructions
ronment.
Do not clean sensitive surfaces
made of rubber, fabrics or the
like with the zero nozzle. With
the fl at jet nozzle keep a dis-
tance 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-pres-
sure hose are damaged.
Do not cover the machine
during operation or use it in a
room without adequate ventila-
tion !
If any of the machines over-
load 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 posi-
tion „OFF“. Refer to section “7
Trouble Shooting”.
Never start the cleaner without
water supply. Even a short wa-
ter defi ciency can damage the
sleeves of the pump.
Operation
Avoid damage to the electric
cables such as squeezing, pull-
ing, knots etc. and keep them
away from sharp or hot objects.
Avoid damage to the high-pres-
sure 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.
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 fol-
lowing:
• Never dismount the high-
pressure hose from the
machine during operation.
Disconnect the machine 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 inter-
ference in the machine it
should be disconnected and
the system relieved of pres-
sure by activating the trigger
of the spray handle.
Repair and Maintenance
Only carry through the mainte-
nance operations described in
the operating instructions. Only
use original NILFISK-ALTO
spare parts.
Do NOT make any technical
modifi cations to the high-pres-
sure hot water washer.
Warning!
High-pressure hoses,
nozzles and couplings are
important for the safety when
operating the machine. Only
use the high-pressure hoses,
nozzles and couplings pre-
scribed by NILFISK-ALTO!
For major repairs, please
contact your nearest NILFISK-
ALTO service organisation.
Mains power connection
This product is intended for
stationary installation only
and is supplied without a
power cord! Only let an au-
thorized 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 dimen-
sions to carry the load (am-
perage) stated on the data
plate of the machine.
• Make sure that the instal-
lation (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 le-
gislation, we strongly recom-
mend you to connect the ma-
chine to a power source with
a Residual Current Device
(RCD) which will dis connect
the power supply if the leak-
age 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 !
