Cleaning and care

DANGER – RISK OF ELECTRICAL SHOCK!

► Always remove the plug of the charger 5 from the power socket before

cleaning the appliance! There is a risk of electric shock!

Do not immerse the handset or the charger 5 in water or other liquids!

WARNING – PROPERTY DAMAGE!

► Do not use detergents or solvents. They can damage the plastic surfaces.

NOTE

Never open the housing of the charger 5 or the toothbrush! They cannot be

resealed in a watertight manner.

1) Dismantle the charger 5 for cleaning:

– Hold the lower part of the charger 5 ﬁrmly and tilt the top part, which

contains the brush holders 4, towards the rear.

2) Clean the upper part of the charger 5 under running water. If any tooth-

paste residue in the brush holders 4 cannot be removed, soak the upper part

of the charger 5 in warm water and then rinse out the brush holders 4.

3) Clean the lower part of the charger 5 only with a soft, slightly damp cloth.

4) Remove the brush head 1 from the handset. After use, clean the brush

heads 1 thoroughly under running water.

We recommend cleaning the brush heads 1 in a standard commercial

denture cleaning ﬂuid every 2–4 weeks.

The brush heads 1 are equipped with so-called indicator bristles (the

outer, light-blue bristles). These bristles lose their colour to show that the

brush head 1 needs to be changed. Change the brush head 1 when the

indicator bristles lose their colour.

5) Clean the interdental brush r after each use under running water. You

should replace the interdental brush r after about 3 months of regular

use, or when the bristles start to bend outwards.

6) Clean the ﬂoss attachment e under running water after every use. If it is

damaged, however, it must be replaced.

7) To clean the drive shaft 2 and the handset, hold them under running water

for a short while. Hold the handset so that the drive shaft 2 is pointing

downwards at an angle.
