Preface
This service manual contains detailed description of the main repair work on the cold high
pressure washer POSEIDON 4.
Repair work requires a suitable working place with the necessary water and power supply.
If operating errors are evident, draw the customers attention to the ”Operators Manual”.
A fault in the high pressure washer can have several causes as described in the section on
troubleshooting.
Refer to the illustrated ”Spare Parts Catalogue” during repairs. It shows the assembly position
and the sequence in which the individual components should be assembled.
See ”Technical Service Bulletin” (TSB) sheets. They include information on technical
modifications that have been made after this repair manual was made.
”Technical Service Bulletin” sheets are also valid as a supplement to the spare parts list until
publication of a new edition.
”Service Manual” and ”Technical Service Bulletin” should be available at the workshop, where
the repairs are carried out.
It is not permitted to give them to third parties.
Use original Nilfisk-ALTO spare parts only.

Safety instructions
5
For your own safety
ESD measures
(electrostatic discharge)
Observe valid safety regulations
for electrical equipment. In
particular, observe the following
regulations:
IEC 60335-2-79
EN 60335-2-79
Additionally:
Also see national regulations
Before using the cleaner, always
read the ”Operators Manual” and
keep it readily available.
Only allow the high pressure
cleaner to be used by persons
who have been trained in its use
and who have been explicitly aut-
horized to use it.
Repair work should be carried
out by persons instructed in
electrical installations or by
trained electricians only.
Take the following ESD precautions before carrying out any
repairs to the electronics:
 Touch the earth conductor before repairing the cleaner
( to discharge electrostatic charge from your body ).
 Wear wrist band if necassary.
 Use a conductive floor covering or a conductive table cover.
 Never touch the printed circuit board or electronic components
( always hold on to plastic ).
 Transport electronic components in conductive packaging
( e.g. ESD bag ).
