Thanks guys,
I tried dewaltservicenet.com but that was a disaster, they are rebuilding the site i think (nothing worked).
I am in Australia and dewalt here reckon they never imported any scroll saws but mine is a Type 1 made in Canada and is marked 788XE which I have found out was the imported model into Australia. Have little chance of finding one here!
Perhaps I should be asking if anyone has had this problem and found an easy-fix for it? That a complete novice could master!
cheers Michael
