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.
6 Clean the cutter and guard under the tap.
7 Shake off excess water.
8 Put the cutter back into the guard.
9 Place the shaving heads in the shaving head
holder.
10 Place the retaining ring on the shaving head.
11 Align the arrows on the retaining ring with the
projections in the shaving head holder. Turn
the ring clockwise until it clicks to indicate that
the ring is fixed.
