1. Maintenance of the hair clipper's knife head: Children's hairdressers used at home are basically waterproof. After trimming the baby's hair, remove the knife head, use the attached small brush to clean the broken dandruff along the direction of the blade, and then clean the knife head with water. After cleaning, be sure to wipe it dry to prevent rust. After the cutter head is completely dry, drop a few drops of lubricating oil on the blade. Remember to replace the cutter head regularly.

2. Maintenance of the hair clipper's fuselage: clean the broken hair on the motor head of the fuselage with a small brush. Do not flush the motor head with water to prevent water from entering the fuselage. Do not clean the fuselage with acidic substances. It is best to wipe the fuselage with neutral detergent.

3. Battery maintenance of the hair clipper: in order to maintain the service life of the battery, it is best to put it away after it is fully charged. Under normal use, the battery should be discharged and recharged at intervals. If it is not used for a long time, it should be recharged at intervals.
