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.
Very good expirience with owner-manuals.com.
5 Stars; In future if necessary, i´ll download manuals on this site.
