Good for you! Every time I took my Janome 4900 to the dealer for its annual check-up, I would complain about the tension and the repair person would say everything was fine and don't play with the tension. Well, I finally talked to a different repair person and he told me to go ahead and try to adjust it myself. The type of fabric and the type of sewing I wish to do sometimes call for different tensions than the 'auto' mode. Now, I adjust as needed and am very happy with my machine.
