There's certainly no reason to take one of the big machines in for servicing when most of us are just a phone call away from great service. As for maintenance, my Gammill is made so I can open the top and side for cleaning. The bobbin case assembly easily comes out for cleaning. I keep it clean and oiled and it has given me great service for the past 12 years, over 1,000 quilts quilted, with no trip to the dealer. Had to edit because I forgot to mention that I have put in new switches, brushes and a fuse; but their online manual is a great help if you do not want to call the dealer.
