How to use an adjustable ratcheting wrench?

[username132]

I have a ratcheting wrench as pictured here but never figured out how to use it and can't find instructions online for this particular design. Draper did not supply any with the tool when I got it. There seem to be a few different designs of adjustable ratcheting wrench available.

Thanks but my wrench is of a different design so that video doesn't help.

Instruction were on back of packaging, though it's just a matter of using it like any ratchet device the wheel will lock in one direction and move freely in the other.

I haven't got one of those, but isn't it just a matter of setting the across flats size of the nut and then putting it on one way to tighten and the other to loosen? Or should it be that with the one flat of the nut against the flat jaw, the other opposite flat lines up with the big arrow there?
