COATS 9500R Electro-Hydraulic Tire Changer - Manual (Page 10)

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 lifts and in the final stage of the move-
ment, the tool rotates. Ensure that the arm is fully
raised for complete rotation of the tool. If the tool is not
required to rotate, lift the arm at only 3/4 of the move-
ment.
6. Operate the control (#2 fig.13) to position B: The
tool older arm lowers and is properly blocked when the
maximum pressure valve is activated, producing a
characteristic hiss.
If the tool is required to rotate when the arm is raised,
lower the arm to about 1/4 of the movement and lift it
again to engage the rotation mechanism.
7. Operate the control (#2 fig.13) to position C: The
tool holder carriage moves to the right. Turn the switch
to position D: The tool holder carriage moves to the left.
8. 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.
Before lifting the toolholder arm be sure
that nobody is standing in the operational
area or areas of danger.
9. To open and close the chuck, operate the appro-
priate control (#1 fig.14).
When opening the chuck ensure that the
jaws do not contact or hit other parts of the
machine.

10. Press the emergency STOP button (#2 fig.14):
This renders all controls inoperative.
Turn the emergency knob counterclockwise and
press the reset button located on the electric cabinet
to resume normal working conditions.

Note: If one of the two hydraulic movements
reaches the end of its course, the speed of the other
movement is appreciably increased: Interrupt the
control engaged and operate only the desired move-
ment in order to get normal operating speed.
Note: Turn the machine OFF after every mounting
or demounting operation, if the time before the next
operation is longer than 5 minutes.
