Motor cooling fan inspection and cleaning

WARNING!
These operations can only be carried out by trained
and qualified personnel.
Periodically clean the motor cooling filters to prevent the
motor from overheating, especially if the vacuum cleaner is
used in a dusty place (2, Fig. 5).

Inspection

Filter chamber seal check
Figure 14
If the gasket (1, Fig. 14) between the container and the filter
chamber (3) fails to guarantee tightness:
■ Loosen the four screws (2) that lock the filtering chamber
(3) against the vacuum cleaner structure.
■ Allow the filtering chamber (3) to lower down and tighten the
screws (2) once it has reached the tightness position.
If an optimal seal cannot be obtained and the gasket (1) is
torn or cracked, etc. it must be replaced.
