Inspection prior to starting

5. Inlet
Prior to starting, check that:
■ the filters are installed
■ all latches are tightly locked
■ the vacuum hose and tools have been correctly fitted into
the inlet (5)

WARNING!
Do not use the vacuum cleaner if the filter is faulty.
WARNING!
The Mod. "3997W - 3997WC" vacuum cleaner is not
provided with quick-fit coupling of the suction hose,
therefore the hose must be fixed to the Ø120 inlet
hose with a clamp.
