Inspections prior to starting

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

Starting-up

- Lock the castor brakes "E" (if present) before starting
the vacuum cleaner (fig. 6);
- press the buttons "B" - fig. 4.
-

Operation

Check the flow rate:
when the vacuum cleaner is operating, the pointer of the
-
vacuum gauge ("A" - fig. 7) must remain in the green zone
(OK) to ensure that the speed of the intaken air does not
drop below the safety value of 20 m/sec;
- if the pointer is in the red zone (STOP), it means that the
speed of the air in the hose is below 20 m/s and that the
vacuum cleaner is not working in safety conditions - clean
or replace the filters;
- when the hose is blocked, the pointer of the vacuum
gauge must switch from the green zone (OK) to the red
zone (STOP).

ATTENTION DANGER !
If the vacuum cleaner is Class M or H, only use hoses
with diameters that comply with the indications in the
"Technical Specifications" Table in order to prevent the
air speed from dropping below 20 m/sec.
ATTENTION DANGER !
When the vacuum cleaner is operating, always check
to make sure that the vacuum gauge pointer remains
in the green zone (OK).
Consult the "Troubleshooting" chapter if faults occur.
-

Shaking the main filter

Depending on the quantity of dust cleaned up, shake the
main filter by means of the lever "J" (fig. 8) when the vacuum
gauge pointer ("A" fig. 8) switches from the green zone (OK)
to the red zone (STOP).
ATTENTION DANGER !
Stop the machine before shaking the filter.
Do not shake the filter whilst the machine 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 pointer still remains in the red
zone (STOP) even after the filter has been shaken (consult
the "Main filter replacement" section).
-

Stopping - emergency stopping

Press the push-buttons "B" (fig. 4).

Emptying the container

ATTENTION DANGER !
Turn off the machine and remove the plug from the power
socket before proceeding with this operation.
Check the Class of the vacuum cleaner.
