Hello,
Oiling the trimmer is very simple. It is only necessary to apply oil to the blades. Simply apply one or two drops of oil directly to the blades while running. This should be done before each use.
You should have gotten a bottle of the blade oil with your clipper. If you have also lost this, you can buy a bottle of Wahl clipper oil from shaveroutlet.com. see link below
