4.4. Using the filter shaking system
This operation must only be performed with the machine switched off once the motor has
come to a complete halt.
The filter shaking system is best operated every time before use and after prolonged
operation.
Move the vacuum cleaner using the handle provided ( A ). For greater convenience, the
most frequently used accessories can be placed in the special accessory basket ( B ).
Caution!_________________________________________________________________
During vacuuming, avoid rolling up or twisting the flexible hose.
On the front of the vacuum cleaner is a vacuum meter indicating the degree of vacuum
inside the vacuum cleaner.
If, with the vacuum cleaner working and the vacuum inlet free, the
"BLOCKED FILTER"
light indicator comes on, the filter will have to be shaken by means of the special lever. If
the indicator light remains on, clean and replace the filter.
Caution! _________________________________________________________________
Never use the machine with the filter blocked.
Caution! _________________________________________________________________
If the indicator light comes on and the vacuum cleaner still indicates irregular
pressure, the flexible hose or vacuum accessory may be blocked. If necessary, this
will have to be cleaned and the cause of the blockage eliminated.
