Manual Override
Use only the supplied manual override crank to reposition the actuator hub when using
the manual override feature.
1.
De-energize the actuator.
2.
Insert the hex end of the manual override crank into the manual override adjustment
point on the face of the actuator.
3.
Rotate the manual override crank in the direction indicated by the arrow on the label.
4.
While holding the manual crank in the wound position, rotate and hold the red lock
shaft approximately 10° then release the manual crank to lock the actuator hub in
place.

Note:
Insert and slightly rotate the manual crank in the direction indicated by the arrow
on the label to unlock the actuator hub. Alternately, the actuator hub automatically
unlocks when power is applied to the actuator, and returns the actuator to normal drive
and spring return operation.
IMPORTANT:
Applying excessive torque to the manual override or running the
manual override with a power tool may damage the internal components of the
actuator and cause premature failure. At the end of travel, the rotational resistance
increases; do not force the actuator hub past this point.
