Maintenance Section
- 31 - EN
Work done on motors or other electrical component parts must only be performed by a specifically
trained electrician, authorised by the Safety Manager.
Always use tools that are in perfect condition and specifically made for the operation to be done.
The use of unsuitable tools or tools not in good condition could cause serious damage.
(***) For Air Series Vacuums, do not consider.
4.3 Maintenance operations
Attention!
All the described operations must be done with the plug disconnected from the power socket.
Before starting any maintenance or cleaning job, always wear adequate protective clothing,
eyewear and/or gloves according to the type of job to be done.
For smooth vacuum cleaner operation, a number of controls are best made periodically:
➢ Check to see whether the filter is worn or has become too permeable.
➢ Make sure the sealing gaskets of the motor head base, of the filter-holder ring and of the
container are working efficiently.
➢ The electrical parts (plugs, switches, cables, etc.) must not be faulty.
➢ The screws and nuts must always be tight.
➢ Make sure the container is not overfull. This should be emptied when the vacuumed material
has reached 3/4 of maximum capacity.
➢ Check the integrity of the flexible vacuum hose and accessories to be used.
➢ If the flexible hose is perforated, the power of the cleaner will be reduced and dust and
liquids will leak into the environment.
➢ For vacuums with electric panel: A qualified operator must periodically verify the cables’
tightening in the electric components of the electric board: with prolonged use of the
vacuum, the vibrations can loosen the tightenings and cause important damages to
components.
➢ For vacuums with compressor:
For maintenance operations of the compressor, see the specific manual.
However, it is necessary to check the oil level of the compressor periodically, the absence of
oil in the compressor will damage it.
