- Remove hairs from the chamber and shaving unit
using the long bristled brush (fig. 11 and 12).
once per 3 months: shaving slots, hair chamber
and shaving unit (guards and cutters).
(With oily skin or when using pre-shave lotion: once
per month)
• First follow the directions corresponding to fig. 9-12.
Then proceed with the directions corresponding to
fig. 13-22.
- Release (1) and remove the holder (2) from the
shaving unit (fig. 13).
- Slide one shaving head (guard and cutter) from the
holder (fig. 14). Remove only one shaving head
(guard and cutter) at a time for cleaning to
ensure that the cutters and guards do not
become mixed.
Each cutter has been ground together with the
guard. If the guards and cutters are mixed, it may
take some weeks before optimal shaving
performance is restored.
If the shaving performance has become noticeably
less after cleaning, change only the cutters over.
- Clean the cutter by brushing only in the
direction of the arrow using the short bristled
brush (fig. 16).
- If you have a very dry skin, or if degreasing liquid
(e.g. alcohol) has been used to clean the shaving
heads, lubricate them with one drop of light
machine oil (fig. 18 and 22).
As an alternative to using light machine oil for
lubrication you may use the specially formulated
Philishave cleaner/lubricant type 389 SHC/1
available from authorised Philips dealers and
Philips Service Centres.
