Description of the
Operating Cycle
6.1 — Starting up and cutting cycle
• Ensure that the machine is not in emergency stop condition;
if it is, release the red mushroom button (1).
• Select the cutting speed on the switch (3):
position 1 = 40 rpm
position 2 = 80 rpm
• Press the start/reset button (2): green light will go on.
• Place material to be cut in the vice (4) and clamp the part
into place by handwheel (5).
• Grip the handle (6) of the HEAD control arm and press the
button, checking that the blade is turning in the direction
indicated (if not, invert the two phase leads) and that suffi-
cient coolant is flowing.
• When starting to cut with a new blade, in order to safe-
guard its life and efficiency, the first two or three cuts
must be made while exerting a slight pressure on the
part, so that the time taken to cut is about double the
normal time (see below in the chapter on “Material classi-
fication and choice of blades” in the section on
Breaking
in the blade
).
• Press the red emergency button (1) when there are condi-
tions of danger or malfunctions in general, so as to stop
machine operation immediately.
