Cleaning and maintenance
Regular cleaning guarantees better shaving
performance.
Be careful with hot water. Always check if the
water is not too hot, to prevent your hands from
getting burnt.
Shaving unit
When you clean the appliance, it is not necessary
to take the shaving heads (cutters and guards)
apart. If you want to take them apart, be sure not
to mix up the cutters and guards, since grinding of
the cutters in the guards only guarantees optimal
performance for each matching set. If you
accidentally mix up the sets, it could take several
weeks before optimal shaving performance is
restored.
The easiest and most hygienic way to clean the
appliance is to rinse the shaving unit and the hair
chamber with hot water every time you have
used the appliance.
1 Switch the shaver off, remove the
powerplug from the wall socket and pull
the appliance plug out of the shaver.
