A:Answer Hi there, this is Kelly with Dyson. It sounds like you are referring to the initial machine assembly, in which the amplifier loop gets attached to the base of the machine. You should be able to just place the loop on top of the base, press down, and it will click in to place. We also have a "Getting started" video on our website here that may help: https://www.dyson.com/support/journey/guides/305158-01?machineId=305158-01
If you still have trouble, feel free to contact us directly via email at askdysonUS@dyson.com.
Best wishes,
Kelly
