I'm having a problem with the cone gears, which appear to easily get stuck.
I took it to a local pool shop who said they dismantled it and found a lot
of hair inside, which they cleaned out. The cone gear tube at the top
still didn't move freely and, when I asked about it, the repairer said
that it didn't matter. I don't think he's right. I'd like to dismantle
the bug myself, but I can't find how to do it. Has anyone done it and
could describe how, or know of a repair manual that gives instructions?
