Adjusting Position Stops
The G-Series Cylinder Actuators have both open and closed position stops. See Figure 2 for position
stop identification.
Figure 2 – Position Stops
The position stops are factory set and do not require adjustment unless the actuator has been
disassembled or actuator orientation has been changed.
Adjusting the Open Position Stop
On 6A and 12A cylinder actuators, the Open Position Stop is located in the end of the extension cap
opposite the cylinder. See Figure 2.
The actuator must be mounted before adjusting the position stop.
1. Loosen the Open Position jam nut.
2. Adjust the Open Position screw to the proper position. Counterclockwise rotation of screw
increases the stroke, clockwise rotation of screw decreases the stroke.
3. Lock the Open Position screw in place with the jam nut.
