Motor cooling fan inspection and cleaning
WARNING!
These operations can only be carried out by trained
and qualied 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 (1, Fig.17 for CTT models
and 2, Fig. 17 for CTS models) are in a good condition and
correctly xed.
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 ba󰀪e plate
inside the ltering chamber.
Scrape inlet (3, Fig. 17) from the outside and remove the
deposited waste as indicated in gure 17.
Filtering chamber tightness check
If the gasket (1, Fig. 18) between the container and the
ltering chamber (3) fails to guarantee tightness:
■ Loosen the four screws (2) that lock the ltering chamber
(3) against the vacuum cleaner structure.
■ Allow the ltering chamber (3) to lower down and tighten the
screws (2) once it has reached the tightness position.
The gasket must be replaced if it is torn, cut, etc.
Replace the gasket (1) if the degree of tightness is still not
optimum.
Separator cleaning and replacement
(optional)
[ NOTE ]
If there is only a dust deposit on the separator (3, Fig. 19)
allow the dust to drop through the central hole.
The separator (3, Fig. 19) should rst be disassembled in
order to be perfectly cleaned:
■ Use the lever (1) to remove the cover (2) together with
the primary lter.
■ Unscrew the two screws and remove it from the
container.
Replace the part if it is excessively worn.
Assemble the components in the reverse order of
disassembly.
