Maintenance operations
Caution!
All the operations described here following must be executed after unplugging the machine.
Before starting any maintenance or cleaning operation, wear the appropriate personal safety devices
such as goggles, gloves and dust mask suitable to protect the operator from breathing particles of the
substance to be vacuumed and to safely perform the work required.
To ensure the vacuum efficiency, it is recommended to check the machine on regular basis as follows:
Every day
Check that the collection container is not full; it is recommended to empty the collection container
when the collected material fills ¾ of its maximum capacity.
Check the conditions of the suction flexible hose and of the accessories to be used . Any hole, crack or
fissure in the flexible hose will reduce suction power and disperse the vacuumed dust into the
environment.
Every week
Clean the vacuum regularly, removing dust deposits. The thickness of the deposited dust must not
exceed 2mm.
Remove any layers of dust on the wheels.
Every 6 months
Check that the head basement sheath, the filter holding ring sheath and the collection container
sheath are hermetic.
The electrical units (plugs, switches, cables and so on) must have no faults or defects.
Screws and nuts must always be tightened.
Clean the deflector inside the suction hose on regular basis to prevent dust accumulation inside the
suction unit.
Remove the side carters protecting the turbine and vacuum any dust deposit within the suction unit.
Check the filter conditions.
The filter must not be too breathable.
There must be no cuts and holes and the sewing must not be worn. Check that the filter holding ring is
tightened. In the event any of the aforesaid circumstances occur, replace the filter as indicated in
section 5.4.
