Abstract
An actuator is manually released by lifting the handle relative to at least one detent to translate a release shaft along its axis, wherein the lifting step selectively positions an end of the release shaft in a first desired axial position relative to one of a gear train and an output shaft. The handle can be rotated relative to at least one detent to rotate the release shaft about its axis to one of the at least three positions. The handle may be released to translate the release shaft along its axis and position an end of the release shaft in a second desired axial position relative to the one of the gear train and the output shaft. The end of the release shaft is maintained in the desired position in the second desired axial position.
