3 Tests
All Nilfisk-Advance systems are tested in order to comply with the requirements of
system safety regulations. They have fulfilled the technical safety demands according
to the following special regulations:
- Technical Dust Test
- Mechanical and Electrical Test
- Noise Technology Test
DIN EN ISO 3744
- Additional Dust Explosion Protection Test

4 Categories of application
This Nilfisk machine is suitable for removing dusts of the following categories of
application:
“U“ suitable for removing hazardous, dry, not inflammable dusts whose MAK*
limiting value is greater than 1 mg/cm³ (comparable to the new dust class “L“
- light hazard - defined by EN 60335-2-69).
“S“ suitable for removing hazardous, dry, not inflammable dusts whose MAK
limiting value is greater than 0.1 mg/cm³ (comparable to the new dust class
“M“ - medium hazard - defined by EN 60335-2-69).
“C“ suitable for removing hazardous, dry, not inflammable dusts with all MAK
limiting values (comparable to the new dust class “M“) as well as dry, not
inflammable dusts of carcinogenic substances (comparable to the new dust
class “H“ – high hazard – defined by EN 60335-2-69). The cleaned air is fed
back to the workplace atmosphere.
“K1“ suitable for removing hazardous, dry, not inflammable dusts with all MAK
limiting values as well as dry, not inflammable dusts of carcinogenic
substances. The cleaned air is fed back to the workplace atmosphere
(comparable to the new dust class “H“).
*maximale Arbeitsplatz-Konzentration, maximal workplace concentration
Explanation
Since May 1998, Europe has a common norm. Dust removing systems are from now
on divided into three dust classes L, M and H. Older test certificates remain valid until
December 31st, 2002. “Category of application“ is a synonym for “dust class“.

Noise emission
Sound pressure level measuring as described in DIN EN ISO 3744.
According to the machine guideline Appendix 1, point 1.75 f, the highest sound
pressure level is measured at 1 m distance from the machine at a height of 1.6 m.
The highest value is reached on the right side (view down on the inlet):
77 dB(A).

6 General notice on safety
Only original Nilfisk spare parts may be used.
The machine may only be operated by instructed and authorised individuals.
Liquids, aggressive gases, flammable materials or smouldering particles should not
be removed.
The machine may only be used for cleaning dry surfaces and is not suitable for
outdoor use.
The power cord should not be damaged by being driven over, squeezed, pulled tight
or around sharp corners. Keep the power cord away from heated surfaces.
The power cord should be checked at regular intervals for signs of damage or
ageing.
Do not use the machine when the power cord is not in perfect condition.
Only original Nilfisk-Advance spare parts should be used when replacing the power
cord.
When the mains plug is replaced, splash-proof protection and mechanical safety
must be assured.
The replacement of the power cord or the mains plug should be carried out by a
competent person.
After use, before cleaning or any maintenance or adjustment work the mains plug
must be unplugged.
Before connecting the cable, the dust-producing system has to be shut down.
MAINTENANCE
Regular maintenance test: check the bounce separator for damage, the integrity of
the system, the filter and the functioning of the control system. Nilfisk-Advance offers
maintenance contracts which guarantee constant performance and value
preservation of the machines and their technical safety functions by regular check-
ups.

7 Filters and emptying systems
The installed main and exhaust filters are approved by the German Trade
Association Institute for Safety at the Workplace (BIA). The transmission factors are
lower than the limiting values required by relating regulations.
The installed filters normally have a long service life. Exchange of filters should only
be carried out by Nilfisk-Advance Service.
Without the appropriate emptying system, the machine does not match the
requirements specified by relating regulations. In this case, danger to health
cannot be excluded.

8 Initial operation
Please read these notes of safety before initial operating.
The application scope of the machine is marked on the rating-plate.
Industrial vacuum cleaners are exclusively designed for removing settled dusts.
Extractors are designed for removing dust at that very place where it is produced.
Having removed the system from packaging, check it for completeness and
transportation damage. In case of damage or missing parts please contact Nilfisk-
Advance immediately. Before connecting the vacuum cleaner to the mains supply,
check that the voltage of the machine specified on the rating-plate corresponds with
the mains voltage.
Switch the motor on to control its direction of rotation.
When it is wrong, a red lamp at the switch housing flashes up.
Extractors: an arrow on the motor housing shows the right direction of rotation.
Working for a long time with the wrong direction of rotation heatens the
vacuum cleaner’s surface up to over 80°C.
When the direction of rotation is wrong two phases in the mains supply (not within the
machine) need to be exchanged. All electrical sockets of the workplace should have
the same phase sequence in order to operate the system in all areas of the
workplace.
Systems with antistatic design (B1)
These machines are not suitable for removing explosive materials, dusts with an
extremely low minimum ignition energy of less than 1 mJ and inflammable liquids.
Do not use others than conductible original Nilfisk-Advance accessories.
Use couplers that only allow connecting and disconnecting the system in voltage-free
condition.
Antistatic systems must be equipped with a protective circuit breaker or a blowout
fuse 16 A (delayed-action fuse).
The use of coupling devices and adapters is not allowed.
The system is ready for use when all equipment has been connected.

9 Adjusting the automatic gear change of the minimum airflow
Use the performance profile to adjust the cutoff point for the minimum
airflow of extractors. First of all, find out the minimal airflow that ensures
a good operation of the dust-producing system. Mark this value on the x-
axis, then draw a vertical line from here to the curve. Now draw a line
parallel to the x-axis from the point of intersection to the y-axis. This
value describes the vacuum that has to be adjusted at the vacuum
switch when the minimal airflow is no longer sufficient.
When adjusting the vacuum, you have to connect an appropriate
measuring device parallel to the vacuum switch. Throttle the airflow at
the suction inlet until the required value is reached. Now calibrate the
cutoff point by the adjusting screw of the vacuum switch.
When the minimal airflow falls short, the following happens after a few
seconds:
- the red warning light flashes up.
- the floating contact in the switch housing switches. This contact (6 A at
a
voltage of 230 V, AC11) manages the connection of the control circuit
of
the dust-producing system to the extractor or to control an external
optical or acoustical signal.
