SusieQOH, yes, your Bernina 150 needs to be oiled. Your manual will show you how to oil the bobbin/hook area. If you don't take your Bernina in for a full-service (at least every 5 years) your sewing machine could get gummed up with old oil and freeze-up.
There are other things a sewing machine tech will take care of while they have your machine. We will check and set the timing, balance the tensions, polish off any burrs that may be on the hook or needle plate, check the motor, and do a deep clean.
