Rechargeable shaver
HQ 561/A
CoolSkin
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.

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 21) cannot be closed.
Cause:
1. The cartridge has not been positioned correctly.
2. The cartridge has not been pushed far enough into the shaver.
CIRCUIT DESCRIPTION
The working of the power supply can be diagrammatically represented in the following blocks: B1. power plug B2. rectifier B3. electronic on/off switch B4. up-converter B5. motor control B6. charging circuit B7. battery B8. motor
To show the differences between the NiCd version (HQ561) and the NiMH version (HQ562), we have combined the electrical diagrams of these versions.
B1. Power plug
The power plug of the two versions is identical and has been made specific for these shavers by means of two notches in the shaver plug. The transformer supplies an alternating voltage of approx. 5 V in unloaded condition. The relay switches between 145 and 185 V= in loaded condition and in this way adjusts the secondary voltage, depending on the mains voltage range of 100-130 V~ or 200-240 V~.
- 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.
- Remove the slide cover (item 21) and cartridge
(item 20).
- Push the edge of the hair chamber up with your thumb
until the snap connection unlocks (see ÔXÕ in exploded view).
- Remove 3 A1 screws.
- Remove the cover (item 14).
- Use a screwdriver to push the connecting plate (item 17)
up at a connecting strip (ÔZÕ in exploded view).
- Tilt the motor slightly to detach the snap hooks of the
hair chamber.
- Lift the motor and the PCB out of the housing.
- The cover (item 14) contains a sticker that is permeable
to gas yet impermeable to water.
- This sticker may not be removed under any
circumstances.
- The entire drive unit (item 10) is supplied as a single part
to guarantee optimal sealing of the gear shafts.
- When reassembling the shaver, the sealing ring (item 2)
must be placed onto the housing.
- A new sealing ring must be used to ensure a proper
sealing of the shaver.
- To guarantee that the shaver is completely watertight, only
the original screws may be used.
B2. Rectifier The secondary voltage of T1 is rectified by bridge rectifier D2. Load signalling takes place by means of green LED D1. Although in the HQ562 load signalling can also be controlled by IC1 and take place via Ledn, we have opted for the solution indicated in the diagram for the sake of uniformity.
B3. Electronic on/off switch
If a pulse is generated via on/off switch SK1, interface IC2 will ensure a stable on/off position via inverters IC2a and IC2b. TS5 makes it impossible to switch the motor on when the shaver is connected to the mains.
B4. Up-converter
Inverters IC2c and IC2d have been configured as an oscillator and together with TS3 and L1 they provide a voltage that is higher than the battery voltage.
B5. Motor control
Motor control takes place via MOSFET TS4. The higher gate voltage (approx. 4.2 V) is produced by the up-converter and is rectified by D5. Zener diode D6 eliminates voltage peaks.

B6. Charging circuit
As NiMH batteries may not be continuously loaded with a high charging current, the HQ562 has a timer IC (IC1). This IC controls TS2 in such a way that a current of 200 mA is supplied to the battery for about 8 hours, after which TS2 switches to a trickle charging current of 25 mA. D3 and D4 suppress high voltage peaks. This circuit is not required in the HQ561 because in this shaver the NiCD battery is continuously charged at 200 mA via R8. The value of R8 equals the internal resistance of TS2.
B7. Battery
The 4/5A NiCd battery of the HQ561 has a capacity of 1200mAH. The capacity of the AA NiMH battery of the HQ562 is 1100 mAH.
B8. Motor
The motor is of the permanent magnet type. 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 as well. As TS5 makes it impossible to switch the motor on when the shaver is connected to the mains, D7 is now placed on the PCB.
GENERAL
Some resistors are not indicated in the electrical diagram. These are resistors of 0 ½ which serve as jumpers across print tracks or as interconnectors between the layers of the double-layer PCB.
