Operating Instructions
4.0 Controls
Before operating the machine ensure that you thor-
oughly 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
machine is turned off. The power required is minimum
when the hydraulic cylinders are not in use.
2. Press the chuck rotation pedal to the right: The
chuck rotates clockwise. Press the other pedal: The
chuck rotates counterclockwise.
3. Operate the control (#1 fig.13) to position A: The
chuck arm moves upwards.
Operate the control (#1 fig.13) to position B: The
chuck arm moves downward.
4. Operate the control (#1 fig.13) to position C: The
tool holder carriage moves to the right.
Operate the control (#1 fig.13) to position D: The tool
holder carriage moves to the left.
Fig.13
5. Operate the control (#2 fig.13) to position A: The
tool holder arm moves to the right.
Turn the switch to position B: The tool holder arm
moves to the left.
6. By operating the controls in one of the diagonal
positions, the two adjacent movements are achieved
simultaneously. This operation affords considerable
time saving in the intermediate operations, but
requires a little practice.
7. To lift the tool holder arm, depress the pedal (#1 .
14) and hold handle (#2 fig.14).The arm is balanced by
a spring-loaded mechanism and the effort required is
minimum.
If the tool holder arm is not correctly locked
in the working position serious injury may
result to the operator and to the machine.
When locking the arm into working position be sure
to use enough force to ensure a proper lock. The heavy
metal construction can easily absorb the force.

8. To turn the tool remove pin (#2 fig.14).
Be sure that the lock pin is properly fitted.
9. To open and close the chuck, operate the appro-
priate control (#1 fig.15).
When opening the chuck ensure that the
jaws do not contact or hit other parts of the
machine.

Note: Turn the machine OFF after every mounting
or demounting operation, if the time before the next
operation is longer than 5 minutes.

reaches the end of its course, the speed of the other
movement is appreciably reduced: Interrupt the con-
trol engaged and operate only the desired movement
in order to get normal operating speed.
