Motor cooling fan inspection and cleaning

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

Tightness inspection

Hoses check
Make sure that connecting hoses are in a good condition and
correctly fixed.
If the hoses are damaged, broken or badly connected to the
unions, they must be replaced.
When sticky materials are treated, check for possible clogging
along the hose (3, Fig. 17), in the inlet and on the baffle plate
inside the filtering chamber.
Scrape inlet (3, Fig. 17) from the outside and remove the
deposited waste as indicated in figure 17.
Filtering chamber tightness check
If the gasket (1, Fig. 18) between the container and the
filtering 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
GB
torn or cracked, etc. it must be replaced.
