) at the safety fence and on
the right side of the machine (see
Figure 8) have a
diameter of 120 mm.
•
All parts of the extraction system, incl. hoses, must be
included in the earthing measure.
•
Use a 120 mm diameter suction hose to connect the
suction system to the machine's suction nozzles (

•
The extraction system for chips and dust must have an extraction capacity of at least 1800 m
3
/h at a speed
of 25 ... 30 m/s.
