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

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

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 manualwas 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 spare parts only!

Safety instructions

For your own safety

Repairs should only be
made by someone who
has received proper
instructions for the job or
who is a qualified
electrician.

Observe national safety directives and
regulations for the electrical engineering
trade, in particular:

IEC 60335-2-69
EN 60335-2-69

Before starting the equipment, be sure to
read the accompanying operator manual,
and keep it close as ready reference.

The equipment should only be used by
persons who have been instructed in its
use and are authorized to do so.

ESD (electrostatic
discharge)

Observe the following ESD precautions before any repair of or near
electronic parts:

Touch the protective conductor to discharge your own body.

Possibly wear an anti-static wrist strap.

Use a conducting floor or tabletop.

Never touch a circuit board or electronic components always hold

it by the plastic or insulation.

Transport electronic parts in conductive packaging (e.g. special

ESD packages).
