SERVICE MANUAL

SM MC 3C_ MC 4M Ver.1.0_March 2015

Preface

This service manual contains detailed description of the main repair work on the cold high

pressure washers MC 3C & MC 4M

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

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.
