Maintenance operations
Attention!
All the described operations must be done with the plug disconnected from the power socket.
Before starting any maintenance or cleaning job, always wear adequate protective clothing, eyewear
and/or gloves according to the type of job to be done.
For smooth dust collector operation, the following periodic maintenance is necessary:
Check to see whether the filter is worn or has become too permeable.
Make sure the sealing gaskets of the motor head base, of the filter-holder ring and of the Longopac®
container are working efficiently.
The electrical parts (plugs, switches, cables, etc.) must not be faulty.
The screws and nuts must always be tight.
Make sure the Longopac® container is not overfull. This should be emptied when the collected material
has reached 3/4 of maximum capacity.
Check the integrity of the flexible collect 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.
Attention!
It is recommended that this machine is services by NFE or its authorized dealers.
