Maintenance operations

Attention!
All the described operations must be done with the plug disconnected from the power socket.
Before starting any maintenance or vacuuming job, always wear adequate protective clothing, eyewear
and/or gloves according to the type of job to be done.
For smooth dust collector operation, a number of controls are best made periodically:
➢
Check to see whether the filter is worn or clogged.
➢
Make sure the sealing gaskets of the motor head base, of the filter-holder ring and of the container are
working efficiently.
➢
The electrical parts (plugs, switches, cables, etc.) must not be damaged.
➢
The screws and nuts must always be tight.
➢
Make sure the container is not overfilled. This should be emptied when the vacuumed material has
reached 3/4 of maximum capacity.
➢
Check the integrity of the flexible vacuum hose and accessories to be used.
➢
If the flexible hose is perforated, the power of the dust collector will be reduced and dust and liquids
will leak into the environment.
➢
For dust collectors with electric panel: A qualified operator must periodically verify the cable
connections in the electric components of the electric board. With prolonged use of the dust collector,
the vibrations can loosen the connections.
Warning!
All maintenance and repair jobs must be performed directly by NFE or its authorized dealers.
