I am a new festool owner. I just recently purchased a CT 36 AC and a compact cleaning kit. Perhaps I purchased the wrong set of cleaning tools since I cannot seam to connect the extensions to the hose. The hose and the extensions appear to be the same diameter. ??? Is there something I can get that will allow me to connect the two? I can connect the crevice tool directly to the hose, but I would like to use the extensions. Thanks.
