4Remove and clean one set at a time.
5Separate the cutter from the head and rinse clean under hot water.
Do not clean the razor heads with the brush.
Do not clean more than one cutter and head at a time, since they are all matching sets. If you accidentally interchange the cutters and heads, it could take several weeks before optimal shaving performance is restored.
6Replace the set back into the Head Assembly in such a way that the sides with the little holes point to the middle of the shaving unit.
Make sure that the two pointy edges of the head fit exactly into the recesses.
7Repeat the process for the other two sets of razor heads.
8Replace the frame.
9Press down and turn wheel clockwise until it locks into place.
10Replace the Razor Head Assembly back on razor.
