Wowery, smowery, you're a popular dude! :)
I, too, hope you're still around, and could have a copy of your manual, too!
Actually, I have a 4" model (#315-11782), but this one sounds very similar.
I, too, have great difficulty in bringing back the wheel. In fact, right now it's sitting under my bench, seemly "permanently" retracted. It shouldn't be this hard, should it?
Thank you muchly!!
