4 While holding Razor Head Assembly in
one hand, press center wheel down while
turning counterclockwise to release and
lift out frame. Set frame aside.
5 Remove and clean one cutter and comb, at
a time.
Do not clean more than one cutter and comb at
a time since they are all matching sets. If you
accidentally interchange the cutters and combs, it
could take several weeks before optimal shaving
performance is restored.
6 Cutter should be held with cutters facing
up and brushed in an upward motion.
Clean razor comb with long bristles of
brush in a circular motion.
For optimum performance, razor cutters and
combs should be cleaned in a degreasing liquid
(e.g., Norelco Razor Cleaner, model RC1776, or
alcohol) and lubricated with Norelco Razor
Lubricant, model AL80, or one drop of mineral oil
(in the center of the head).This helps prevent
wear of shaving heads.
7 While holding Razor Head Assembly in
one hand, replace cutter and comb back
into the Razor Head Assembly.
8 Repeat the process for the other two sets
of cutters and combs.
