Closing the clips requires the FT1357 Clip Closing Pliers. That specific tool is what you need to properly seat the clips into the connection points. When you use them, keep the pliers squared up on the clip connection points and hold them square all the way through the closing motion. Using the wrong tool risks an improper seal, so it's worth tracking down the FT1357 before you start the assembly.

For closing the clips, the instructions call for FT1357 Clip Closing Pliers. The clips need to be positioned squarely on the clip connection points and kept square while you close them, and those pliers are the tool specified for doing that correctly.
