Dear customer. The equipment must be charged at the specified voltage to ensure the best performance of the product, avoid damaging the battery and extend its service life. It is an ideal holiday gift. Before use: Confirm that the knife head is firmly installed and adjust the appropriate limit comb length. Clean the blade head and apply lubricating oil to it to reduce friction. ​

During use: Keep the blade moving parallel to the scalp to avoid pulling on the hair. First, cut the long hair into sections and then trim it finely with a limit comb. ​

After use: Disassemble the blade head to clean the broken hair, rinse with clean water (waterproof model), dry and apply lubricating oil. Avoid colliding with the blade head when storing.
