4. Insert a screwdriver through the plastic funnel shield, if present, and through the access
hole, engaging the screwdriver with the gear-like plastic disc.

of Actuator Removed).
5. Turning the disc CW (as viewed from the front of the actuator) causes the switch to
operate nearer to the CCW end of actuator rotation. Each click of the cam represents
about a 3° change in the switch point.
6. Adjust the disc so that the switch just operates.
Speed Adjustment The actuator selection tables beginning on page 3 list the actuators that are adjustable
speed. The timing of the adjustable speed actuators is varied by a slotted adjustment screw
on the lower left side of the front housing. Refer to
Figure-40. Turning the screw CW
decreases the speed. Total timing can be increased to about ten times the normal. Take care
not to turn the adjustment screw too far CW as this will stall, but not damage, the actuator.
If stalling occurs, turn the screw CCW until the actuator resumes operation. The total
adjustment is normally 3-1/2 turns on the adjustment screw.
