Controls

Before operating the machine ensure that you have
well understood the operation and function of all the
controls.
1.
To turn the machine on, rotate the ON/OFF switch
to position 1 and press the reset button: the pump
motor starts turning and remains in operation until the
1
machine is turned off . The power required is minimum
when the hydraulic cylinders are not in use.
4-1
IT IS SUGGESTED TO TURN THE MACHINE OFF
AFTER EVERY MOUNTING OR DEMOUNTING
OPERATION, IF THE TIME BEFORE THE NEXT
OPERATION IS LONGER THAN 5 MINUTES.
2.
Press the pedal on the right (1, Fig.4-1): the chuck
rotates clockwise. Press the other pedal: the chuck
rotates counter clockwise.
3.
Operate the control (Fig.4-2) to position A: the chuck
arm moves upwards.
Operate the control (Fig.4-2) to position B: the chuck
4-2
arm moves downwards.
4.
Operate the control (Fig.4-2) to position C: the
toolholder carriage moves to the right.
Operate the control (Fig.4-2) to position D: the
toolholder carriage moves to the left.
5.
By operating the controls in one of the diagonal
positions, the two adjacent movements are achieved
simultaneously. This operation aff ords considerable
time saving in the intermediate operations, but requires
a little practice.
IF ONE OF THE TWO HYDRAULIC MOVEMENTS
REACHES THE END OF ITS COURSE, THE SPEED
OF THE OTHER MOVEMENT IS APPRECIABLY
REDUCED: INTERRUPT THE CONTROL ENGAGED
AND OPERATE ONLY THE DESIRED MOVEMENT
IN ORDER TO GET NORMAL OPERATING SPEED.
