6.3 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’s 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’s 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.
• Check that the safety filter is not too dirty or clogged.
•
Clean the deflector inside the suction hose on regular basis to prevent dust accumulation inside the suction unit.
•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 6.4.
Every 24 months
• It is necessary to replace the bearing of the suction unit to ensure the endurance of the pump’s efficiency.
WARNING!
To ensure the vacuum’s efficiency and safety, Delfin S.r.l. recommends an overhaul at the
Manufacturer’s technical service workshop every 24 months.
WARNING!
Any maintenance and repair operation not included in the above mentioned ones must be executed by
the Manufacturers technical service workshop or by DELFIN authorised service centres.
WARNING!
In case of dust outflow from the engine, turn off the vacuum immediately and call the authorised service
centre applying for assistance,
