TIPS FOR REPAIR

-  Remove the shaving unit to prevent damage during repair.
-  Remove the slide cover (item 21) and cartridge (item 20).

-  Use a screwdriver to push the connecting plate (item 17) 

up at a connecting strip (‘Z’  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.

sealing of the shaver.

-  To guarantee that the shaver is completely watertight, only 

the original screws may be used.
