Basic clipper maintenance includes cleaning the hair clippers. Remove any stray hairs thoroughly with a soft brush. Oil the blades about once per month with lubricating oil. Store the device in a dry and safe space (e.g. the box it came in). Charge your lithium-ion battery-powered clippers as they drop to 70%. Do not wrap the cord around the clipper while storing. This may decrease the cord’s lifespan. Always use the supplied charger with the voltage and wattage meant for your clipper.
