The reason I queried the olive oil is that different oils have different properties, for instance, I believe that linseed oil is regarded as a 'drying' oil, believe it or not. I would have thought a specific machine type oil would be better for a machine, and I don't see how the oil could contaminate the food as you are using it in an area that is not in contact with food. However, if TMX HO suggests oilive oil I would run with that as they should know what is best.
