Help adjusting a Premier Mounts TV mount?
I have a Premier Mounts AM2-B TV mount. Here it is.

The joints on the swing-out arm can be adjusted by removing the plastic cap on the joint (labelled "Adjustable Tension" on the diagram). I can't get the end cap off. The caps are so flush with the metalwork that I can't get a fingernail underneath. I've tried using a blunt knife, but I've actually damaged the plastic with no sense of movement from it. These caps are not coming off, and I feel like I'm missing something. The manual simply says "Remove end caps".
Can anyone help with this?
