6 Maintenance and service
The weighing machine must be treated carefully and cleaned regularly. It is a precision instrument.
For maintenance-work, the balance must be separated from the power supply (remove power adapter
plug from socket). Also ensure that the balance cannot be reconnected to the power supply during the
work by a third party.
Take care during cleaning that no liquid penetrates into the appliance. If liquid is spilt on the balance, the
latter must immediately be disconnected from the electricity supply. The balance may only be used again
after it has first been checked by a service engineer.
The connections on the rear of the appliance and the power adapter may not come into contact with
liquids.
Regularly dismantle the weighing pan and the weighing pan holder and remove any dirt or dust from
under the weighing pan and on the weighing machine housing with a soft brush or a soft, lint-free cloth,
moistened with a mild soap solution. The scale and the holder can be cleaned under running water. Take
care that both parts are completely dry before they are re-installed on the scale.
