Preface
Preface
There are only minor differences between the
NEPTUNE 4 hot-water high-pressure cleaner and
NEPTUNE 3 and NEPTUNE 5 line of products.
This service manual mainly refers to the
concerning sections in the service manuals
NEPTUNE 3 and NEPTUNE 5 / 7.
Repair work requires a suitable testing workplace
with the necessary power supply.
If operating errors are evident, refer the customer
to the user manual.
A fault in the cleaner can have a number of causes.
Refer to Chapter E for troubleshooting.
Also refer to the illustrated spare parts list (p/n
301002627) for your repairs. This shows you the
location of the individual parts and the sequence in
which they are assembled.
Read the ”Service / Technical Information” sheets. They include information on technical modifications
that have been made after this service manual was printed.
”Service / Technical Information” sheets are also valid as a supplement to the spare parts list until a new
edition is published.
Service manuals and “Service / Technical Information” sheets should be available at the place where
repairs are carried out.
Transfer to third parties is not allowed.
Use original Nilfisk ALTO spare parts only!

Construction
The external design of the Neptune 4 hot-water
high-pressure cleaner is identical to the Neptune 3
line of products. As far as sensors, control,
functionality and electronics are concerned, there
are no differences to the Neptune 3 series as well.
There are only two differences compared to
Neptune 3:
The Neptune 4 series has the NP5 hp-pump (1)
installed (like the Neptune 5) and the machine is
equipped with an additional hydraulic accumulator
(2)(see also STI MPW-040).
For further details about the construction of the
machine, refer to the Neptune 3 and Neptune 5 / 7
Service Manuals (chapter C resp. chapter 3).

The machine comes as standard- (with storage tray for accessories, tools, etc.) or X-model (with hose
reel instead of the storage tray). Upgrading with a hose reel is possible.

Function
There are no functional differences between the Neptune 3 line of products and the Neptune 4 series.
For further details on the subject of function refer to the Neptune 3 Service Manual (chapter D) as well as
the user manual of the respective machine.
For details about the function of the NP5 hp-pump refer to the Neptune 5 / 7 Service Manual (chapter 4).
