[3] Take out the coupling hub and coupling spacer from the detached motor unit. Twist the coupling hub
or coupling spacer on the motor side to align the screw holes with the hole for the tool to go through.
Then remove two screws with a 2 mm hex wrench.
* If there is only a coupling hub on the motor unit side, then there is a coupling spacer on the actuator
side which can be removed by pulling.
* If both coupling hub and coupling spacer are present, pull them apart.
(They should separate with a gentle pull.)
[4] Fit the protruding part of the coupling hub into the groove of the replacement jig (large), and
temporarily hold them together with two M 3x3 Allen screws (tighten just enough so that the coupling
hub does not fall off).
[5] Turn the shaft to move the slider about 0.5 mm to 1 mm from the mechanical end on the home
position side.
[6] Fit the groove of the replacement jig (large) assembled in [4] over the protrusion of the actuator.
