Do you need to ol this machine - Elna 7200 Computerized Sewing Machine

The manual will probably make no reference to oiling this machine but will recommend cleaning out the bobbin holder with a little brush regularly and getting it serviced by a tech annually. These newer machines have an oiling wick under the bobbin and nylon gears so regular oiling is not so critical. My tech told me that I could still oil into the wick occassionally which I do between services. Certainly if it is sounding noisier than normal then a single drop of quality clear Sewing Machine oil into the middle of the bobbin holder under where the bobbin sits, won't hurt it. The brushing out to remove fibres, threads and dust is important to keep the race area clean so the lubrication can work.
