How to Fix a Sagging Mini C-Arm (Text Version)

1. Get a 3/16 Allen wrench and a small flat-head screwdriver.

2. Prying gently with the screwdriver, remove the rubber cap (circled in the picture) at the base of arm.

3. Tighten the screw beneath the cap firmly, but not as tight as possible. If you over-tighten the screw, the arm movement will be stiff.

4. Test your arm movement for the desired tension and repeat steps 1-3 as needed.

5. Replace the rubber cap and use your mini C-arm as usual.

In the majority of cases, the steps above are sufficient to return a mini C-arm to firm positioning. If these steps don't work, it may be an indication that you have a deeper issue requiring a replacement part in the arm.
