10 — Maintenance
10.1 — Foreword
Attention!!
All maintenance and cleaning operations must be
carried out when the vacuum is off and disconnected
from the electricity main.
The suction unit needs no particular maintenance or
lubrication.
Remember, however, that correct use and servicing are
essential if the safety and efficiency of the vacuum are
to be guaranteed.
To ensure regular and constant operation and to prevent
the warranty from becoming void, only ever use genuine
Nilfisk-Advance A/S spare parts when repairs are
needed.
10.2 — Checks and inspections on start-up
The customer should proceed with the following
inspections to ensure that the vacuum has not been
damaged during transportation.
10.2.1 — Before starting:
Check that the mains voltage value corresponds to
that for which the machine is preset (see data plate in
paragraph 3.1 fig. 1);
10.2.2 — With the vacuum operating
check that all the air seals are perfectly tight; check
that all fixed protections are efficient; proceed with
suction tests using the same materials as those used
during work. This will ascertain whether all parts of the
vacuum operate correctly.
10.3 — Routine maintenance
Strictly comply with the following operations to ensure
that the vacuum remains in a constantly reliable
condition.
10.3.1 — Before each work shift:
Check that all warning and danger plates are fixed and
legible.
Replace them if they are damaged or incomplete.
Check that the waste container is empty.
Empty it if this is not the case. See paragraph 8.3.
