This clipper uses a very powerful motor that delivers nearly 10,000 cycles per minute to the blade. This results in a very strong audible hum, but is completely normal to its operation. Don?t settle for a weak clipper! Note: clipper has a power screw, it has been adjusted for peak efficiency before leaving the factory. However, if voltage in your home is low, you may need to re adjust it. To adjust power screw, use the plastic brush, a screwdriver or a thin coin to turn power screw in a clockwise direction until the arm strikes the coil, making a noise. Then, slowly turn power screw out (counterclockwise), just until noise stops. This is the maximum power setting. Also, it is important to oil your blades after each use.
