I don't really have a problem with my Juki HZL-E61 sewing machine (love it!), I just would like to know if I can oil it myself, or if it needs to be oiled by a Sewing Machine Repair Expert? I have the Instruction Manual for HZL-E61, however there are no instructions to oil it, and I've recently read that Juki sewing machines need to be oiled frequently. Bad for me, I've never oiled mine.....I do though remove the lint from underneath often
