cleaner.
Ensure that the machine is reg-
ularly serviced by Authorised
Nilfisk-ALTO dealers in accord-
ance with the maintenace plan.
Failure 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 Nilfisk-ALTO
service department or an au-
thorised specialist work-shop for
all other maintenance or repair
work!
Testing
The cleaner conforms to the
German „Guidelines for Liquid
Spray Jet Devices“. The high-
pressure cleaner must be sub-
jected to a safety examination
in accordance with the „Acci-
dent Prevention Regulations for
Working with Liquid Spray Jet
Devices (BGV D15)“ as required,
but at least every 12 months, by
an authorised inspector.
After all repairs or modifica-
tions to electrical equipment,
the protective conductor resist-
ance, the insulation resistance
and the leakage current must
be measured. Furthermore, a
visual inspection of the mains
power lead, a voltage and cur-
rent measurement and a func-
tion test must be carried out.
Our after-sales service techni-
cians are at your disposal as au-
thorised inspectors.
The complete „Accident Preven-
tion Regulations for Working
with Liquid Spray Jet Devices“
are available from the Carl Hey-
manns Verlag KG, Luxemburger
Strasse 449, 50939 Cologne or
from the appropriate associa-
tion of employers’ liability insur-
ances.
The pressure-bearing parts of
this high-pressure cleaner have
been manufactured in accord-
ance with § 9 of the German
Pressure Vessels Ordinance
and successfully subjected to a
pressure test.
Safety devices
Unacceptably high pressure is
fed back without residual pres-
sure via a bypass line into the
intake line of the pump when the
safety device is tripped.
If the conveying capacity falls
below a fixed value, the built-
in flow monitor automatically
switches off the oil burner. The
oil burner is set to continuous
ignition. As an additional protec-
tion mechanism, a thermo-sen-
sor is integrated in the chimney
of the heat exchanger. As such,
the appliance cannot overheat.
The safety devices are factory
set and leaded, and must not be
adjusted.
