sure cleaner.
Ensure that the machine is
regularly serviced by authorized
Nilfi sk-Alto dealers in accordance
with the maintenace plan. Failure
to do so will void the warranty.
CAUTION!
High-pressure hoses, fi ttings
and couplings are important
for the safety of the cleaner.
Use only high-pressure parts
approved by the manufactu-
rer!
The power cord must not differ
from the version specifi ed by the
manufacturer and may only be

thorized Nilfi sk-Alto equipment

Testing
The cleaner conforms to the Ger-
man „Guidelines for Liquid Spray
Jet Devices“. The high-pressure
cleaner must be subjected to a
safety examination in accord-
ance with the „Accident Preven-
tion Regulations for Working
with Liquid Spray Jet Devices“
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 current
measurement and a function test
must be carried out. Our after-
sales service technicians are
at your disposal as authorised
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.
Unloader valve
Pump pressure is reduced by
means of an "unloader valve"
which returns water to the inlet
side of the pump at a minimum
pressure. The point at which
this occurs is set and sealed
at the factory and must not be
adjusted.
