The manual is great help for me, i'm happy to have it,thanks
 ;
Very pleased with manual except that a few more details in the drawings might make the job (not yet done, tut-tut) easier. Should be adequate though. Actually I didn't have to pay for this anyway as I was given credit for another item that wasn't quite complete. Good service, then.
