Aye William,
A few psi in each leg. Some of us put a little pressure in, others, none at all. I'm one of the latter and can't remember the details.
SteveL and SteveH have both written 'threads' with details about this afore on the site, try the 'Search' tab at the top of the page. If you get no other more useful replies, I shall dig out a manual and quote you the 'gospel'.
Good night, Bill.
