Front wheels locking!

[brooksy]

Hi guys, I've just received my fs2 today(Thanks to jens). Fitted all my gear in it and set it up but when I put full lock on the steering either way it locks up!.(the wheels won't spin)
I can't for the life of me figure out why it's doing it!.
I know it's got to be something simple but my mind has gone blank

Can anybody tell me what it is please so I can get it sorted for Worksop on Sunday.


Many thanks Phill.
