The saw-tooth thread is to allow one-handed rapid closing of the vice I think. You use the quick-release lever to open the vice, hold your part in place then push the jaw inwards, it should ratchet over the thread until it contacts the part, then you should have up to one turn of the handle to tighten.
The reason it's jumping on the release is probably due to stiction in the sliding jaw ways. Either full of crud, lack of lube or the wear faces are lapped together so finely that lube is squeezed out straight away leaving the faces dry. A quick go-over with a scraper or ground file to put some oil flaking in it would help there.
That's not the worst part. It'll dangle a carrot or two in front of you two. There's some stuff in there I never even knew they made, until seeing the catalogues.

I never ratchet down the vice i always use the quick release to slide down push the lever down and turn a half turn as thats its take up of slack before it bites to the material been held in the vice
I made the mistake of putting on a grey primer which shows up when it gets chipped. I think putting the blue straight onto the bare metal would've been better.
Well I hate to do this but I picked up this little gem in a job lot, for a fiver!

It's so minty and original, I daren't use it. Probably just tidy it up and sell it to a vice museum!
;D
