Motor cooling fan inspection and cleaning

WARNING!
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 (1, Fig. 5).
Any other servicing should be performed by an authorized
representative.

Commissioning after longer standstill

Before recommissioning after a longer standstill, measure the
insulation resistance of the drive motor.
With values ≤ 1 kΩ per volt of nominal voltage, the winding
is too dry. In such case, do not use the vacuum cleaner and
contact the manufacturer's service center.
Any other servicing should be performed by an authorized
representative.

Tightness inspection

Hoses check
Figure 14
Make sure that connecting hoses (1) 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 (2), in the inlet and on the baffle plate inside the
filtering chamber. Scrape inlet (2) from the outside and remove
the deposited waste as indicated in figure 14.
Filtering chamber tightness check
Figure 15
If the gasket (1) between the container and the filtering
chamber (3) fails to guarantee tightness:
■ Loosen the four screws (2) that lock the filtering chamber
US
(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.
The gasket must be replaced if it is torn, cut, etc.
Replace the gasket (1) if the degree of tightness is still not
optimum.

Cyclone
[ NOTE ]
If there is only a dust deposit on the cyclone (3) allow the
dust to drop through the central hole.
The cyclone (3) should first be disassembled in order to be
perfectly cleaned:
■ Use the lever (1) to remove the cover (2) together with
the primary filter.
■ 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.

Disposing of the vacuum cleaner

Dispose of the vacuum cleaner in compliance with the laws in force.
