11 Maintenance and servicing
The balance must be treated carefully and cleaned regularly. It is a
precision instrument.
Regularly dismantle the scale pan and the scale pan holder and remove
any dirt or dust from under the scale pan and on the balance 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 balance.
The regular maintenance of the balance by your Precisa Service
Representative will guarantee unrestricted functioning and reliability
over many years and will extend the lifespan of the balance.
DANGER
For maintenance-work, the balance must be separated from the
power supply (remove power adaptor 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 immedia-
tely be disconnected from the electricity supply. The balance may
only be used again after it has first been checked by a Precisa
Service Engineer.
The connections on the rear of the appliance and the power
adaptor may not come into contact with liquids.
CAUTION
Never use solvents, acids, alkalis, paint thinners, scouring pow-
ders or other aggressive or corrosive chemicals for cleaning, since
these substances attack the surfaces of the balance housing and
can cause damage.
