Only thing I can say on this is that:there is only one year warranty DW788.I had three of them in the past 7 year.Don't take this wrong .but they don't hold up every day use.For me they last close to year.First one was the motor when out on it,gave me a second one .The inside arm broke on second one,that one hold up for about year half .The number 3 I still have it.but I had to take to get it fix," tension knob on it when bad on it.I t could be luck .Anyway I have a Excalibur now and there is a story behind on that one too,but I'M not getting into that one
