9.2.1 Manual Operation Procedure
You can manually advance/retract control of the tailstock centre by pressing the [TAILSTOCK
ADVANCE/RETRACT] toggle key at the machine control panel when the machine is set to [JOG]
mode.
To advance the tailstock:
1. Select [JOG] mode
2. Select the [TAILSTOCK ADVANCE/RETRACT] at the MCP
As the tailstock moves the LED indicator above the key will change to the ‘flashing’ state to inform
you that the tailstock barrel is moving. When the tailstock has stopped advancing the LED indicator
changes from ‘flashing’ to ‘ON’ state.
If the LED indicator continues to flash after the tailstock barrel has stopped advancing then this
means that the barrel has moved to its advanced limit position because either you did not load a
workpiece to the machine or the tailstock has not been correctly positioned such that the dead
centre can support the end of the workpiece.
To retract the tailstock:
3. Select the [TAILSTOCK ADVANCE/RETRACT] again.
As the tailstock moves the LED indicator above the key will change to the ‘flashing’ state to inform
you that the tailstock barrel is moving. When the tailstock has stopped retracting the LED indicator
changes from ‘flashing’ to ‘OFF’ state.
