When the TD (transfer device) does not fully open at the waist or mouth, ensuring proper functionality is critical for optimal use. Both actions suggested—tightening the CAS (Closure Adjustment Screw) and moving the EFA (Elbow Flip Arm) proximal—target potential reasons for the restricted opening.

Tightening the CAS can enhance the effectiveness of the closing mechanism, enabling the transfer device to operate more smoothly and achieve a wider opening. This adjustment is important in addressing any slack or misalignment that might be inhibiting full functionality.

Moving the EFA proximal is another practical approach, as it can change the angles and leverage within the device, facilitating a greater range of motion when opening. This method addresses positioning issues that may contribute to the malfunction.

Combining both adjustments provides a more comprehensive solution, making it effective to pursue both the tightening of the CAS and repositioning of the EFA for improved performance of the TD. Therefore, the best course of action is to implement both adjustments to achieve the desired result of a fully functioning device at the waist/mouth.
