Remove the needle plate and the bobbin, there's two spots marked with red, in centre of the bobbin case place a drop of good quality sewing machine oil, and also to the left on the case, beside the tension dial. A drop in both, then run the machine slowly for a minute until the oil has spread through the innards. You can also remove the top cover but this is not covered in the manual as there's the recommendation in the manual to have your machine serviced annually. However, it can be done, unplug, then undo the two screws on top which hold the top cover on. Push down the spool holders, then wiggle the top panel around the lifting handle so you can slide the top panel vertically to the back around the handle. Then look down and oil on the needle bar bearing, turn the flywheel towards you to go through the stitch cycle and you will see the bearing coming around, drop of oil onto it. DONT oil on the right side near the friction drive and motor, just on the left area, metal on metal moving parts.
