be caught or cut off.
Do not touch any moving parts during operation.

The maintenance key is an interlock related key for use with the
machine. It is used to disable the power shutoff feature for axis
drivers except for the spindle while the waterproof cover is open.
This key must be stored with due care by qualified maintenance
