6- Maintenance
6.1 Foreward
The suction unit needs no particular maintenance or
lubrication.
Remember however, that correct use and servicing
are essential if the safety and efciency of the vacuum
are to be guaranteed.
To ensure regular and constant operation and to
prevent the warranty from becoming void, only use
genuine Manufacturers spare parts when repairs are
needed.

that the vacuum remains in a constantly reliable condi-
tion.
