you that the tailstock 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 key again.
