Regular care and cleaning of the cutting heads and blades is essential. It not only enables a better care of your pet's hair, but also makes the clipper work better and longer. In particular, lubricating the cutting head is the most important maintenance operation. Oil should be used regularly on the frictioning parts. This creates a protective layer on the blades surface that reduces friction and prevents  from eccessive wear. Reducing friction also helps the motor and batteries to last longer.
