16 Maintenance and servicing
40
Regularly dismantle the weighing pan and the weighing pan holder and remove any dirt or dust from under
the weighing pan and on the balance housing with a soft brush or a soft, lint-free cloth, moistened with a
mild soap solution.
The weighing pan and the holder can be cleaned under running water. Take care that both parts are com-
pletely dry before they are re-installed on the balance.
The regular maintenance of the balance by your Service Representative will guarantee unlimited function and
reliability over many years and will extend the lifespan of the balance.
