• If there is any reason to believe that it is no longer possible to
operate the balance without danger, the balance is to be immediate-
ly unplugged from the electricity supply (pull out power adaptor) and
secured against inadvertent operation.
• In carrying out maintenance work, it is essential to heed the recom-
mendations in chapter 11 “Maintenance and servicing”.
• The balance must not be operated in an area subject to explosion
risks.
• Take care when weighing liquids that no liquid is spilt into the inside
of the balance or into connections on the rear of the equipment or
the power adaptor.
If liquid is spilt on the balance, the latter must immediately be
unplugged from the mains electricity supply (pull out power
adaptor).
The balance may be operated after it has first been re-checked by a
Precisa Service technician.
• The operating instructions must be read by each operator of the
balance and must be available at the workplace at all times.
