GENERAL
- Cool skin is a new shaving system.
The shaver features a special compartment for
cartridges containing Nivea for Men moisturising
shaving emulsion.
This emulsion is applied to the skin while shaving.
- The shaving unit can be cleaned under a running hot
tap.
The HQ156 shaving heads are made of special
stainless steel for corrosion-free cleaning with water.
- The shaver has a separate trimmer for grooming
sideburns and moustaches.
The trimmer can be flipped open to enable cleaning
of the inside.
- The charging stand of the shaver can be placed on a flat
surface or it can be attached to the wall.
The PCB inside is encased in insulating material.
For this reason the mains cord cannot be replaced if it is
damaged.

TROUBLESHOOTING
- Shaving heads do not move smoothly over the skin.
Cause: not enough Nivea for Men shaving emulsion.
- Shaving performance has decreased.
Cause:
1. Clogged shaving heads.
The shaver has not been cleaned immediately after
use and/or has not been rinsed with hot water or has
not been rinsed long enough.
2. Long hairs in the shaving head.
Clean the cutters and combs individually, since they
are all matching sets.
If the cutters and combs have accidentally become
mixed up, it may take several weeks before optimal
shaving performance is restored.
3. Shaving heads are damaged or worn.
Check the combs for broken or indented lamellae.
Only HQ156 stainless steel Cool Skin shaving heads
may be used as replacements.
- Compartment cover (item 23) cannot be closed.
Cause:
1. The cartridge has not been positioned correctly.
2. The cartridge has not been pushed far enough into
the shaver.
- Shaver does not work when the on/off button is
pressed.
Cause:
Batteries are empty.
- Shaving emulsion has lost its colour or has become
watery.
Cause:
The Nivea for Men emulsion has not been kept at the
right temperature.
TIPS FOR REPAIR
- Remove the shaving unit to prevent damage during
repair.
- To guarantee that the shaver is completely watertight,
only the original screws may be used.
- After the cover (item 16) has been removed, it must
be checked if its sealing has not been damaged.
- The cover (item 16) contains a sticker that is permeable
to gas yet impermeable to water.
This sticker may not be removed under any
circumstances.
- To replace the motor (item 10) or the driving unit
(item 7), screws B1 must be removed first.
Then push the entire unit out of the housing (item 11)
and check if its sealing is damaged.
- The entire driving unit is supplied as a single part to
guarantee optimal sealing of the gear shafts.
CIRCUIT DESCRIPTION
The power module incorporates 4 basic functions:
a. controlling the charging currents
b. electronic on/off switch
c. Battery Low Indicator (BLI)
d. protection circuits
a. Charging currents
During the first 1 hour, quick charging takes place at
1000 mA.
During this period, the green LED is on continuously.
During the first 6 minutes the red LED is on too, to
indicate that there is not yet enough capacity
available for one shave.
After 1 hour, the green LED starts blinking and the
charging current is reduced to 100 mA.
It is kept at this level during the next 2 hours.
Then charging continues at 25mA.
The cells are charged at fixed currents via switching
transistor TS1.
The current is detected by sense resistor R9.
The timers in IC1 adjust the current level via the enable
signal at pin 2 by regulating the conductive time of TS1.
b. Electronic on/off switch.
The motor is switched on via MOSFET TS4.
If a pulse is generated via on/off switch SK1, the interface
IC2 will supply a voltage higher than the cell voltage,
causing TS4 to become conductive.
The next pulse will stop the motor.
IC2 and the surrounding components have been defined
in such a way that humid conditions do not influence
proper functioning.
c. Battery Low Indication.
The red LED of duoLED D5 will start to blink when 70 % of
the cell capacity has been used up.
During shaving, the cells are discharged by the motor
current.
This current is measured via sense resistor R9.
d. Protection circuits.
In case of short-circuited components, C9 and C10 will
separate the contact pins of the stand from the mains
voltage.
R14 and R16 create a small pre-load for the SMPS
converter to prevent an excessive rise of the output
voltage when the shaver is not placed in the stand.
Diode D4 prevents the cells from being shorted by TS1
and protects them against a short-circuit due to a piece of
metal being placed accross the contact pins of the shaver.
R20 protects enable pin 2 against excessive currents
when the charging voltage has the wrong polarity (e.g.
when the shaver has been placed in a HQ5615/HQ5620
stand, which has AC output voltage).
NTC resistor R18 protects the NiMH cells against
overheating. If the temperature rises too high, the charging
unit will switch over from quick charging to trickle charging.
The Zener diode D7 suppresses high voltage peaks during
shaving. Normally, this diode is placed between the motor
solder tags to suppress radio interference (RIF) in the
mains too. TS5 makes it impossible to switch on the motor
when the shaver has been put in the stand.
To ensure proper functioning of the electronics under
humid conditions, the entire PCB and the components
have been shielded with insulating lacquer.
This coating prevents migration of silver from SMD
resistors to the PCB, thus preventing low-ohmic
connections between print tracks.
