3 Remove the shaving heads from
the shaving head holder. Each
shaving head consists of a cutter
and guard.
Note: Do not clean more than one
cutter and guard at a time, since they
are all matching sets. If you accidentally
put a cutter in the wrong shaving
guard, it may take several weeks before
optimal shaving performance is restored.
4 Clean the cutter and guard under
the tap.
Note: You can also clean the cutter and
the guard with the cleaning brush. Brush
carefully in the direction of the arrows.
5 After cleaning, place the cutter
back into the guard.
