POSEIDON 4

SM_POSEIDON 4_en_Ver.1.0_08.2012

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 ).

Preconditions:

-The high pressure cleaner is connected to adequate water and power supply.

Main switch S1 in ”OFF” position.

-There is main voltage to S1.

-Cleaner is still off.

Main switch S1 in ”ON” position.

-Gun closed : The cleaner starts up (if B4 is closed and B3 is closed) until cut-off pressure is

reached => end switch B4 opens => the cleaner stops.

-NOTE ! Static high pressure water between valve block - hose - gun .

-Gun activated: The pressure drops in pressure valve => the end switch B4 is activated =>

the cleaner starts up and runs at working pressure.

-Gun being closed: Working pressure increases to cut-off pressure => end switch opens =>

the cleaner stops.

-Detergent valve: The cleaner running at working pressure and the detergent valve open,

detergent is added by means of the vacuum in the injector to the high pressure water.

Fig. E.1:Troubleshooting 1

Fault Cause Remedy

Pressure drop

- Air in the system.

- High pressure nozzle

blocked / worn.

- Pressure control on the

spray lance is not set

correctly.

- Detergent container empty.

- Water inlet temperature

too high.

 Vent the system by

operating the spray gun

several times at short

intervals .If necessarly

operate the cleaner for a

short time without the

High pressure hose

connected.

 Clean / replace the high

pressure nozzle.

 Set the required working

pressure.

 Change container or close

detergent valve.

 See technical data part ”B”.

Pressure

fluctuations

- Lack of water

- Water inlet hose is too long

or its cross-section too

small.

- Lack of water caused by

blocked water filter.

- Lack of water because

max. permissible suction

height has not been

heeded.

- Pump sucks in air

(suction mode)

 Open water tap.

 Use specified water inlet
