1 Press the EMERGENCY STOP button to take the 200V down to 100V.

2 Position the cam at an angle of 0° and turn the ST14 solenoid to ON (Y037 ST14

NOZZLE CHANGE SOL ENGAGED) to activate the cam lever.

3 Zero the dial gauge when there is no contact between the clutches, and use the

cam handle to rotate the cam to 141°.

4 Verify that the nozzle change clutch is engaged with the holder clutch, and that

the rotary holder is pushed 0.01 to 0.05 mm as shown in the figure below.

5 If the stroke is out of range, adjust by turning the adjusting rod.

WARNING

• Press EMERGENCY STOP before performing this procedure.

• Exercise extreme caution when working on the machine if the cam
