Attention! Risk of material damage!
Only use connection socket DN 7,2 to connect the machine to the air supply
The factory-specified operation pressure must only be altered on the instructions of the service department!
5.5 Chip extraction
• In addition, the vacuum performance must be sufficient to
achieve the required negative pressures and an air speed
of 20 m/s at the connector. (see “Technical data”)
• Check the air speed before putting the machine into
operation for the first time and after essential changes.
• The dust extractor setup must be controlled before the
machine is put into operation for the first time. Check for
obvious defects on a daily basis and the efficiency on a
monthly basis.
• The dust extractor must be connected to the machine
in such a manner that it runs in unison with the
machine.
• The dust extraction hoses must be electrically conducti-
ve and grounded to prevent electrostatic
build up.
• Use dust extractors with reduced dust emission to clean
dust from the machine.
Note: As a rule, all units must be vacuumed during use. A time delayed socket is available as an accessory.
Warning! Risk of injury! The dust extraction hose must be non-flammable and must not conduct electricity! For
this reason, only use genuine FELDER dust extraction hoses!
5.6 Compressed air supply connection
The connection between the machine and the air pres-
sure system is on the rear using a fast connection with a
DN 7.2 type connector.
The pressurised air supply is equipped with a regulator,
filter and a water separator unit.
Set the pressure to 6 bar on the filter pressure controller.
