Controls and indicators (fig. 4)

A. Suction motor start switch;
B. Mains voltage indicator light;
- if the indicator light is on: the electric power is
supplied;
- if the indicator light is off: the electric power is
cut off;
C. Primary filter clogging indicator light;
- if the indicator light is on: the filter is clogged;
- if the indicator light is off: the filter is efficient.

Inspection prior to starting

Prior to starting, check that:
- The filters are installed;
- All latches are tightly locked;
- The vacuum hose "A" and the accessories have
been correctly fitted into the inlet "B" (fig. 5);
- The bag or safety container is installed, if
applicable.
- Do not use the vacuum cleaner if the filter is faulty.

Starting up

- Lock the castor brakes "E" (fig. 6) (if supplied)
before starting the vacuum cleaner;
- Push the button "A" - fig. 4.

Vacuum cleaner operation

Mod. 118 operation
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").
US
C384
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.
WARNING!
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.
WARNING!
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).
WARNING!
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).

Stopping - Emergency stopping

Push the button "A" - fig. 4.
