The suction ring on the NV501 must be pried off toward the open end of the tube. A wide flat blade screw driver between the handle and the suction ring works best. The suction ring doesn't need to be rotated any specific direction for removal. It will take some force to snap back onto the handle during assembly. Rotational orientation is important during assembly, so the suction ring can function as designed.
The hose wire is also soldered to a ground plate in the handle, and a ground lead that contacts the aluminum suction tube . You can see the wires in the 2nd picture of step 4. I assume this is required to eliminate static electric charges that could ignite a dust fire when shorted.
