Edgebander
G 330 / G 360 / G 380
• The machine has to be connected to a dust extractor.
• The dust extraction hoses must be electrically conduc-
tive and grounded to prevent electrostatic
build up.
• 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.
• In addition, the vacuum performance must be suffi-
cient to achieve the required negative pressures and
an air speed of 20 m/s at the connector.
• Check the air speed before putting the machine into
operation for the first time and after essential changes.
• Use dust extractors with reduced dust emission to clean
dust from the machine.

Attention! Risk of material damage! The glue spreading roller is powered by the chain feeding system.
Therefore, when testing the correct sense of rotation of the chain feeder, it is necessary to wait until the
temperature of the glue pot reaches 190°C.
Do not manually start the chain feed remote switch if the glue is not yet fluid!

• It is strictly prohibited to earth the neutral wire. The
main power system must be provided with a neutral
and an efficient earth line. Open the electrical
control panel. Insert the main cable line inside the
cable grip on the machine frame.
• Connect the main cable with the relative joint clamps
of the main switch. Close the electrical panel.
1.
Check the direction of rotation of the motors:
a.
Connect the plug to the power supply.
b.
Turn the machine on for a short time.
c.
Check the rotation direction of the crawler.
d.
If it is incorrect, swap two of the three phases at
the entry to the main switch of the machine.
2.
Because of the auto-reverse, the HF motors energised
by the inverter may turn in the opposite
direction to the crawler.
3.
This problem is solved by checking each individual
motor of the different units (re-trimmer, gluing unit
etc.).
7.5 dust extractors
The quality of the edgebanding, the good functioning and durability of the machine all depend on the
quality of the dust extraction system used.
Setup and installation
Note:
If the machine is equipped with a residual current circuit-breaker (RCCB), then it must be a Type B, sensitive to
universal current RCCB, suitable for frequency inverter operation with a release current of 300mA.
