Fig. 20: Control panel

• Carry out the checks indicated at § 4.3;

• power the machine turning the knob (18);

• set the switch (4) in brake release position;

• the machine is equipped with spindle shaft rotation inverter:

select the spindle rotating direction acting on the switch (9), the position F corre-

sponds to the counterclockwise rotation d irection, while the position R corre-

sponds to the clockwise rotation direction.

It is not possible to start the spindle if a rotating direction has not been selected

before.

The machine stops immediately if the rotating direction switch is operated while

working.

• To choose the clockwise rotating direction or the simultaneous machining

direction [position R of the switch (9)] keep the light push button (8) pressed

while starting the spindle; the relevant pilot light switches on.

Do not operate with simultaneous machining because the rejection risk in-

creases.

• Press the push button (14) to start the spindle motor.

• Press the push button (7) to stop the spindle motor.

4.7.2 Use of the machining guid e

• A protecting device must always be used for the guide machining, so as to avoid

piece sliding and swinging.
