7 Remove and clean one cutter and head at a time.
• Be careful not to mix up cutters and heads. They
are a matched set and if interchanged, it will greatly
affect shaving performance.
8 Separate the cutter from the comb.
9 Only brush the cutter in an upward motion.
Use the short bristled side of the brush.
10 Brush the slots of the razor head.
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).
11 Replace the cutter and razor head in the Head Assembly.
12 Repeat the process for the other two razor heads
(cutters and combs).
13 Replace the frame.
