7 Clean the inside and outside of the comb
with the brush supplied.
For optimum performance, shaver cutters and
combs should be cleaned in a degreasing liquid
(e.g. alcohol) and lubricated with one drop of
mineral oil (in the center of the head). This helps
prevent wear of the shaving heads.
8 Replace the set back into the Shaver Head
Assembly.
Make sure that the two pointy edges of the
head fit exactly into the recesses.
9 Repeat the process for the other two sets
of cutters and combs.
10 Replace the frame and turn the lock
clockwise until it locks into place.
11 Insert the notch of the shaving unit into
the slot in the top of the shaver (1) and
then close the shaving unit (2).
NOTE: If the shaving unit does not close smoothly,
make sure you inserted the shaving heads
properly and that the retaining frame is locked.
12 Put the Protective Cap on shaver to
protect heads.
