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.
