Preface
In this manual you will find
the essentials you need
to know when repairing
wet and dry cleaners of
the Attix 30 and 50 series.
When carrying out repairs,
make sure you ha e a suitable
workbench or the like with the
necessary power supply
a ailable.
If you determine an error
in operation, be sure to
refer the customer to the
user manual.
A fault in the equipment
can ha e 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 indi idual 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.
Repair manuals such as this
are a supplement to the spare
parts list. Please refer to the
spare parts list for any parts
that you do not find in this
manual.
Use original Nilfisk-ALTO
spare parts only!

Safety Issues.
Unplug the machine from it’s power supply socket when not in use and before performing any
ser ice or maintenance work on the machine.
Before starting any ser ice or maintenance work, be sure to read this ser ice manual fully and
keep it close by for reference.
Be sure to obser e any national safety directi es and regulations before attempting to repair or
ser ice your machine.
The machine should only be used by persons who ha e been instructed in its use and are au-
thorized to do so.
Repairs should only be
made by someone who
has recei ed proper
instructions for the job
or who is a qualified
electrician.
For your own safety
ESD (Electro-Static Discharge)
Obser e the following ESD precautions before repairing or working near elec-
tronic parts:
• Discharge any static build up on your own body by touching a properly earth-
grounded source.
• Wear an anti-static wrist strap, if possible.
• Use a conducting floor or tabletop.
• Ne er touch a circuit board or electronic component directly, always hold them
by their plastic frame or insulation.
• Transport electronic parts in conducti e packaging (e.g. special ESD packages).

By sealing the suction opening (1) a high negati e pressure is generated inside the dirt tank
when the motor is running. 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 material from the inside to the outside. The negati e pressure in-
side the dirt tank is reduced ery quickly and the tank wall relie ed of pressure. The dirt that
has adhered to the filter is blown and shaken off, causing it to fall back into the tank. To opti-
mise the cleaning effect, it is recommended to actuate the cleaning button briefly se eral
times.

Automatic Cleaning function
E en with extremely fine dust the automatic filter cleaning function allows you to work constantly
with the same suction performance without ha ing to manually clean the filter. To make it possible
to clean the filter during cleaning work, the filter has been di ided into two hal es by means of two
side seals on the filter holder. The cleaner sucks in dirt through one side while the other side is be-
ing cleaned by a blast of air from the inside to the outside. One solenoid al e (pos 1.) and the the
ser o motor (pos.2 ) control ( e ery 30 sec.) the suction air stream and the blast of air to clean the
filter.

Function
Soft-Start:
The features allows the motor to ramp up to its operating speed which greatly reduces amper-
age spiking at start up. This will prolong the life of the motor.
Main switch:
Two modes can be selected with the main switch:
Man: The turbine starts immediately.
Auto: The turbine waits for an electric 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 ice life of the turbine
- Reduction in noise emission
- Energy sa ings
Automatic starter
Work with an electric tool (grinder, etc.) can be optimised 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.

Troubleshooting
1. Isolate component from the electricity supply.
2. Remo e co er.
3. Apply mains oltage.
Set switch to position “I” at full power.
4. Visual inspection:
Green LED lights up (5 V OK).
Red LED lights up (motor is acti ated).
5. Isolate component from the electricity supply.
6. Remo e the two motor cables from the circuit board and the switch.
7. Connect test lamp 302000764.
8. Apply mains oltage.
9. Test:
“Motor” lamp slowly star it to light up (soft star t).
Set switch to minimum speed.
The brightness of the lamp becomes less.
