Remember, in order to protect your investment, your clippers should be brushed, cleaned & oiled after every use.
How do you lubricate hair clippers?
Oiling the blades reduces friction and keeps the clippers from pulling and snagging as you cut your hair. A drop of oil at the corners of the blade's top, as well as the foot of the blade, is all it takes. After you apply the drops of oil, turn the clipper on to help work the oil in.
