4 Remove and clean one set at a time.
5 Separate 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.
6 Replace 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.
7 Repeat the process for the other two sets of razor heads.
8 Replace the frame.
9 Press down and turn wheel clockwise until it locks into
place.
10 Replace the Razor Head Assembly back on razor.
