Mafell has the best customer service I've ever come across! I emailed them last night and had a reply before 8am!!!
Dear Mr
to realigne the tables of your AD160 you'll have to take a plastic-hammer and carefuly take the one side of table up by give some "hits", so that the tables are aligned again. It is the only way to realigne the table, please be careful not to brake something. But I think, there will be not a problem you'll reach a good result if you follow this instructions and you'll enjoy working with your machine again.
Mit freundlichen Grüßen
