corresponds to 2.5 mm from the mechanical end.

Warning: If the actuator is installed vertically, move it after turning on the controller power
and forcibly releasing the brake. At this time, beware of danger as the actuator
may drop suddenly.
Always provide a support to brace the actuator hand to prevent sudden drop, so
as not to pinch fingers or damage the load.
2) Using an Allen wrench of 2.5 mm across flats, remove the bolts affixing the motor-end cap and
attached cables.
