The primary filter clogging causes the vacuum capacity to be reduced; therefore, it is necessary to:

• shake the primary filter by means of the lever "A";
• if the problem persists, replace the filter (see

"Changing the primary filter").

Mod. 118 M and 118 H operation

Check the flow rate:

• when the vacuum cleaner is operating, the indicator light "C" (fig. 4) must be off to ensure that the speed of the intake air does not drop below the safety value of 20 msec;
• If the indicator comes on, it means that the speed of the air in the vacuum hose is 20 msec and that the vacuum cleaner is not operating in safety conditions. The filters must be cleaned or replaced.
• Close the suction hose; the indicator light "C" (fig. 4) must come on.

DANGER!

If the vacuum cleaner belongs to the M or H class, use only hoses with diameters that comply with the indications in the Technical data table, in order to prevent the air speed from dropping below 20 msec.

DANGER!

When the vacuum cleaner is operating, always check that the indicator light "C" (fig. 4) is off. Consult the "Troubleshooting" chapter if faults occur.

Shaking the main filter

Depending on the vacuumed dust quantity and if the indicator light "C" (fig. 4) comes on, shake the primary filter by means of the lever "A" (fig. 7).

DANGER!

Stop the vacuum cleaner before shaking the filter. Do not shake the filter while the vacuum cleaner is on, as this could damage the filter itself.

Wait before restarting the vacuum cleaner, to allow the dust to settle.

Replace the filter element if the indicator light still remains on even after the filter has been shaken (consult the "Changing the primary filter" paragraph).
