The actuator is factory set to spring return in a
Counterclockwise (CCW) direction.
Clockwise (CW)
To change the spring return direction to Clockwise
(CW), refer to Figure 3 and proceed as follows:
1. Turn the actuator over, release the locking clip
with a flat-blade screwdriver, and remove it from
the coupler.
2. Remove coupler and sleeve from the front of the
actuator, and slide the sleeve off of the coupler.

3. Insert the sleeve into the back of the actuator with
the smooth half of the sleeve inserted first.
Note:
Make sure the widest gap in the sleeve teeth
align with the two guide marks on the back of
the actuator. (See Figure 4.)
IMPORTANT:
When the sleeve is changed from
the front of the actuator to the
back, the actuator’s drive direction
is also reversed.
