2. DUST EXTRACTION CONNECTION
The machine must always be operated with the dust collec-
tion system connected.
Thorough dust collection will remove any foreign body, eli-
minate the risk of breathing dust and is necessary for correct

machine operation.
Dust particles damage the pneumatic elements, dull the bits
and soil the glue.
The pre-milling unit is equipped with a suction hood A (Fig.
2) that is connected to the general dust extraction socket of
the machine. At the same time, this hood acts as a protection
guard for the cutters.

To install it, connect flexible tube B (Fig. 2) with a diameter of
100 mm to collector C (Fig. 2).
Fasten the tube with brackets (not included).
The tube connected to the main dust collection system, must
be positioned in a way to not disturb the operator's move-
