Checking to see if anyone else has lost the pull ring that pushes the push rod to empty out the dirt bin? I ordered a replacement push rod because somehow the pull ring came up missing thinking the pull ring was a part of the replacement push rod and upon getting the part there was no ring. Does anyone know how to get one of these? Do you have to order a replacement cyclone top or what part do I need to get this pull ring replaced? I would sure appreciate some guidance here if anyone knows? I had looked at the exploded drawings of this part and it looked like the ring was a part of this push rod.
