I don't recall that Norelco specifies any lubrication, however, I usually apply a drop of very fine oil, like gun oil, to the heads of my Norelco approximately every 2 months. This procedure has worked for me for many years.

Not with this model that is designed for a close shave, but Norelco and Remington have models that have adjustable length of cut. Both Remington and Norelco are good and both now made in China. I suggest getting a Remington MB 4040 in addition to your Norelco shaver.
