Remove the protective cover from the shaver. If you simply wish to style your eyebrows,usethe longer side of the attachment .
To trim your eyebrows to a shorter length,use the short comb attachment.There are 2 parallel guide bars in the attachment which allow you to set it to other lengths.
Use these guide bars to set the length you require by fitting the attachment,with the teeth facing upwards.onto the metal blade until it clicks into place. Always trim the hairs against the grain.You can remove individual facial and neck hairs close to the skin by using the shaver directly on your skin without the comb attachment.Do not apply too much pressure on the shaver.
