Preface
In this manual you will find
the essentials you need
to know when repairing
wet and dry cleaners of
the Attix series.
When carrying out repairs,
make sure you have a suitable
workbench 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 causes.
Chapter E Troubleshooting
will help you here.
Use the illustrated spare
parts lists for your repairs.
These show you the location
of the individual parts and the
sequence in which they are
assembled.
Read the technical informa-
tion sheets. These will tell you
about any technical modifica-
tions 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 technical
information sheets
should be available at the
site where repairs are carried
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!
Safety instructions marked
with this symbol in
this manual must be ob-
served
to prevent danger to per-
sons.
This symbol is used to
mark safety instructions
that must be observed to
prevent damage to the
equipment and degradation
of performance.
This symbol indicates tips
and instructions to simplify
work and to ensure safe
operation

Safety Issues.
Observe national safety
directives and regulations
for the electrical engineer-
ing
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 installa-
tions.
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 author-
ized to do so.
Repairs should only be
made by someone who
has received proper
instructions for the job
or who is a qualified elec-
trician.
For your own safety.
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).

By sealing the suction opening (1) a
high negative pressure is generated
inside the dirt tank when the motor is
running which keeps this under ten-
sion.
By actuating the cleaning button (2) on
the suction head, an air flap is opened
in the carrier plate, which allows air to
flow into the inside of the filter (3). The
air flows through the filter fleece from
the inside to the outside.
The negative pressure inside the dirt
tank is reduced very quickly and the
tank wall relieved of pressure.
Cleaning is always carried out for a
short time, mainly by relieving the tank
wall in short bursts.
The dirt adhered to the filter is blown
and shaken off, causing it to fall back
into the tank.
To optimise the cleaning effect, we
recommend that you actuate the
cleaning button briefly a number of
times.

Function.
Technical description of automatic starter with speed control
Soft start:
In cleaners fitted with the electronics men-
tioned above, the motor is always started with
a soft start.
Advantages:
The gentle start up of the motor re-
duces the starting currents so that
the mains fuse does not blow during
start up. In
addition, soft start greatly reduces the
load on the turbine
When it starts up. This results in a
considerable increase in the service
life of the turbine.
Main switch:
Two modes can be selected with
the main switch.
Man: The turbine starts immedi-
ately.
Auto: The turbine waits for an elec-
tric tool to be switched on at the
socket.
Speed control:
Speed control has been integrated into
the manual and automatic modes.
Settings on the switch range are possible
from 45° to 135°.
Advantages:
- Optimum adjustment of the
suction power to suit the
application.
- Increase in the ser vice
life of the turbine
- Reduction in noise emis-
sion
- Energy savings
Automatic starter
Work with an electric tool (grinder, etc.) can be opti-
mised by using the automatic starter.
The main switch is set to the “AUTO” position and
the electric tool connected to the socket of the
cleaner. The suction motor is
switched off. When the electric tool is now switched
on, the automatic starter detects.
The flow through the connected machine and
switches the suction motor on.
When work with the electric tool is stopped, the
suction motor switches off after a delay of approx. 3
seconds. The cleaner now stays in the standby
mode until the electric tool is switched on again.
