provided with a scale. The KF 903/1003/1203/1403 coffee grinders are suitable for use in

3.1 Care and cleaning of coffee grinder
The coffee grinder must only be cleaned with a dry cloth.
Do not use an alkaline cleaning agent.
Do not spray coffee grinder with water and/or steam.
Reason: It can result in a short-circuit and therefore damage to the

The coffee grinder should be cleaned at least once weekly and always if soiled.
3.2 Maintenance
If the grinding quality is no longer of the required standard, the grinding discs must be
replaced.
The grinding discs should be inspected for wear after not longer than 12 months.
Periodic checking of the grinding quality and grinding discs must only be
performed by competent specialists and/or service personnel.
3.3 Scale setting (adjustment)
Setting of the scale (with the adjusting knob) makes the fineness of the ground coffee
correspond with the fineness set on the scale (marked).
Setting of the scale must only be performed by persons familiar with the unit
after carefully reading the following instructions.
The basic setting according to 3.3.1 should be made:
- following change of grinding discs
- following inadvertent displacement of the scale
setting
Change of scale setting as 3.3.2 should be performed:
- if the desired grinding fineness does not
correspond with the scale (adjusting knob)
- if an individual setting of the grinding fineness is
desired (customer setting)
