NEPTUNE PE/DE
Original Instructions
NOTE
!
The maximum permissible
working pressure and tempera-
ture are printed on the high-
pressure hose.
Do not use the cleaner if the
high-pressure hose or the
equipment is damaged.
Ensure adequate air circula-
tion. Do not cover the cleaner or
operate it in inadequately venti-
lated rooms!
Store the cleaner where
it will not be exposed
to frost!
Never operate the cleaner with-
out water. Even brief shortages
of water result in severe dam-
age to the pump seals.
Operation
CAUTION!
Unsuitable fuels (e.g. gasoline)
must not be used as they can
explode and catch fire.
Use clean fuel only, free of
moisture and contamination.
Contact your dealer for fuel
source and type recommenda-
tions.
Diesel according to EN 590 (up
to 7% bio diesel) can be used
with the following restrictions:
Maximum storage time in high
pressure cleaner diesel tank: 1
month.
Diesel stored externally for
more than 6 months is not
allowed to be filled into Nilfisk-
ALTO high pressure cleaners.
Diesel EN 590 from an open
container must not be used.
If the machine is to be opera-
ted at fuel stations or in other
potentially hazardous areas,
the machine may only be em-
ployed outside the hazard areas
defined in the German „Techni-
cal Guidelines for Inflammable
Fluids“ applicable at the point
of use due to the potential ex-
plosion hazard posed by the
burner.
Do not use the machine in
closed rooms.
CAUTION!
Do not touch or cover the ex-
haust. Risk of burns and fire.
Maintenance and repair
CAUTION!
Always remove the ignition
key before cleaning or car-
rying out maintenance work
on the cleaner.
Carry out only the maintenance
operations described in the
operating 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
regularly serviced by authorized
Nilfisk-ALTO dealers in accord-
ance with the maintenace plan.
Failure to do so will void the
warranty.
CAUTION!
High-pressure hoses, fittings
and couplings are important
for the safety of the cleaner.
Use only high-pressure parts
approved by the manufac-
turer!
Please contact your local au-
thorized Nilfisk-ALTO equipment
distributor for all other mainte-
nance or repair needs!
Testing
The cleaner conforms to the
German „Guidelines for Liq-
uid Spray Jet Devices“. The
high-pressure cleaner must be
subjected to a safety examina-
tion in accordance with the „Ac-
cident Prevention Regulations
for Working with Liquid Spray
Jet Devices“ as required, but at
least every 12 months, by an
authorised inspector.
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.
