14 Maintenance
14.1 Foreword
The operator must disassemble, clean and service the
vacuum cleaner only when these procedures cannot
cause damage to the personnel in charge for the
maintenance and other people.
Precautions include cleaning before disassembly,
forced ventilation in the room where the vacuum
cleaner is disassembled, cleaning of the place where
maintenance is performed and protective clothing.
Vacuum cleaners for dust class H and M needs to be
cleaned in their exterior parts. Collect the dust or seal it
before the vacuum cleaner is taken out of the danger
zone. All vacuum cleaner components are to be
considered contaminated when they are taken out of
the danger zone, so avoid to shatter the dust.
The suction unit does not require any particular
maintenance or lubrication.
However, remember that correct use and maintenance
are essential if the safety and efficiency of the vacuum
cleaner are to be guaranteed.
To ensure regular and constant operation and to
prevent the guarantee from becoming void, only ever
use genuine Nilfisk-Advance spare parts when repairs
are needed.
For dust class “M” and “H”, it is necessary to close the
suction inlet with a plug during transport or filter
shacking.
14.2 Checks and inspections on
start-up
The customer should proceed with the following
inspections to ensure that the vacuum cleaner has not
been damaged during transport.
14.2.1 Before starting
Check that the mains voltage value corresponds to that
for which the vacuum cleaner is preset (see the plate on
paragraph 3.1, Fig. 1).
Check that all warning and danger plates are affixed
and legible. Check that all protections are installed and
efficient.
14.2.2 During the vacuum cleaner operation
Check that all the air seals are perfectly tight.
Check that all fixed protections are efficient.
Perform suction test using the same materials as that
used during work. This will ascertain whether all parts
of the vacuum cleaner operate correctly.
14.3 Routine maintenance
Strictly comply with the following operations to ensure
that the vacuum cleaner remains in a constantly
reliable condition. During maintenance or repair
procedure, it is necessary to dispose of all the
contaminated objects that cannot be properly cleaned.
These objects must be disposed of in waterproof bags,
according to the law in force.
14.3.1 Before each work shift
Check that all warning and danger plates are affixed
and legible. Replace them if they are damaged or
incomplete.
Check that the dust container is empty. Otherwise,
empty it. See paragraph 8.3.
14.3.2 Every 200 hours (monthly)
Check the tightness of the vacuum cleaner. There must
be no leaks.
Check the condition of the suction hoses and other
accessories. They must not be torn, cut or broken since
this would lower the suction power.
Check that the power cord has not been damaged, torn
or crushed. Check the condition of the main filter. It
must be undamaged, i.e. there must be no tears, holes
or other damage.
Change the filter, if necessary.
14.3.3 Every 2000 hours (once every year)
Check the condition of the suction unit.
Have the vacuum cleaner completely overhauled by
the manufacturer or by an authorized Service Center.
14.4 How to perform the required
inspections
The following instructions show how to perform the
required inspections.
WARNING!
All maintenance and cleaning procedures
must be performed when the vacuum
cleaner is off and disconnected from the
electrical mains.
