Removing - Use a sharp pull and make sure you don't have someone standing behind you.

Don't use the 5-pair punch for anything other than cutting down the cable and seating the C-clip. If you use it to actually punch down your cross-connect wire, it will wear things out, and the terminations are less likely to be reliable. This may vary depending on the brand of 110 and/or punch tools, but in general I would say it's a good idea to stick to the single 110 punch tool after the C-clip has been seated.
