suspension may drift during use, but if they are too tight, the suspension may be dicult to move.

Spring Arm meet.

Extension Arm Brake Screws (Shoulder joint and Elbow joint)
The brake screws at the shoulder joint adjust the right and left movement of the Extension Arm itself.
The brake screw at the elbow joint adjusts the right and left movement of the Spring Arm. When properly
adjusted, each arm will move with relative ease and will stop moving once you let go of it. If the Extension
arm continues to drift left or right after you move it, you will need to tighten both brake screws at the
shoulder joint. If the Spring Arm drifts after you move it, you will need to tighten the brake screw at the
elbow joint. If either arm is dicult to move, you will need to loosen the appropriate brake screws.
