Featuring Wahl’s best corded motor. The motor has 15 percent more power than Wahl’s PowerDrive premium motor for no-snag cutting. Wahls Self-sharpening precision blades stay sharper longer and cuts hair 40 percent faster. If the blades are not oiled, it may be possible the blades will not move. However, even if not oiled, the clipper will usually have enough power to run. If the “voltage” in your home is low, then the clipper’s motor may make a loud noise. There is an adjustment screw on the side of the clipper that will correct that issue (noted in the instructions). Note: This clipper is made to be only used in the USA. If used outside the USA, voltages are different and can affect performance and may damage the product. Save yourself time, money, and headaches between trips to the barber with the best in men’s grooming. Add the Wahl Elite Pro High-Performance Haircut Kit to your cart today! They are not hair and can be simply wiped off.
