I'ld spin the vice round 90 deg before you use it
what do you intend using it for? - in my experience the reason they sit unused for years is they are not very versatile at all.
I had a lovely decent sized 'ALBA' and it went to the big recyclers in the sky
They are handy for cutting dovetails on very small hammer die blocks (slowly)
One hint - dont over tighten the stroke adjustment clamp when you use it, then when the tool digs in and jams (which it will) it will slip, and save the tool / workpiece smashing.
