Attix7_ver.1.0_140105.

In this manual you will find

the essentials you need

to know when repairing

wet and dry cleaners of

the Attix 7 and 19 Gallon

series.

When carrying out re-

pairs, make sure you

have a suitable work-

bench or the like with the

necessary power supply

available.

If you determine an error

in operation, be sure to

refer the customer to the

user manual.

A fault in the equipment

can have a number of cau-

ses. Chapter E Trouble-

shooting will help you

here.

Use the illustrated spare

parts lists for your repairs.

These show you the locati-

on of the individual parts

and the sequence in which

they are assembled.

Read the technical infor-

mation sheets. These will

tell you about any techni-

cal modifications made

after publication of this

repair manual.

Technical information

sheets are a supplement

to the spare parts list until

a follow-on publication.

Repair manuals and tech-

nical information sheets

should be available at the

site where repairs are car-

ried out. Further repair

manuals of the Attix series

may be necessary for

repairs to the equipment.

It is not permitted to give

them to third parties.

Use original Nilfisk

ALTO spare parts only!

Symbols used to mark in-

structions

Safety instructions mar-

ked with this symbol in

this manual must be ob-

served to prevent danger

to persons.

This symbol is used to

mark safety instructions

that must be observed to

prevent damage to the

For your own safety

Repairs should only be

made by someone who

has received proper

instructions for the job

or who is a qualified elec-

trician.

Observe national safety

directives and regulations

for the electrical enginee-

ring trade, in particular:

IEC 60335-2-69

EN 60335-2-69

DIN VDE 105 part 1:

operation of electrical

power installations

DIN VDE 0701/0702:

repair, modification and

testing of electrical instal-

lations

Before starting the equip-

ment, be sure to read the

accompanying service

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 authori-

zed 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 them by the plastic or insulation.

• Transport electronic parts in conductive packaging

(e.g. special ESD packages).
