Electrical equipment
CAUTION!
Never spray electrical equip-
ment with water: danger for per-
sons, risk of short-circuiting.
Switching on the cleaner may
cause voltage fl uctuations.
Voltage fluctuations should not
occur if the impedance at the
transfer point is less than 0.15
If in doubt ask your local elec-
tricity supplier.
Maintenance and repair
CAUTION!
Always remove the plug from the
mains plug socket before clean-
ing or carrying out maintenance
work on the cleaner.
Carry out only the maintenance
operations described in the op-
erating instructions. Use only
original Nilfisk-ALTO spare
parts.
Do not make any technical mod-
ifications to the high-pressure
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.
2 Description
2.1 Purpose This high-pressure cleaner has
been designed for professional
use. It can be used for clean-
ing agricultural and construction
equipment, stables, vehicles,
rusty surfaces, etc.
The cleaner has not been ap-
proved for cleaning surfaces
which comes into contact with
food.
Chapter 5 describes the use of
the high-pressure cleaner for
various cleaning jobs.
Always use the cleaner as de-
scribed in these operating in-
structions. Any other use may
damage the cleaner or the sur-
face to be cleaned or may result
in severe injury to persons.
