Important instructions, which involve safety, are highlighted
with the appropriate mark:

1.2 Safety recommendations

When using the weighing equipment in surroundings with
increased safety requirements, the corresponding regulations
must be observed:

The weighing machine may only be used with the power
adapter supplied exclusively for use with the weighing
machine.

Before inserting the power adapter, the user must ensure that
the operating voltage stated on the power adapter agrees with
the mains voltage.

If not, please contact Customer Service at the address above.
If the power adapter or its cable is damaged, the weighing

machine must immediately be disconnected from the
electricity supply (pull out the power adapter).

The weighing machine may only be operated from mains
electricity supply with a power adapter which is in perfect
condition.

If there should be any reason to believe that it is no longer
possible to operate the weighing machine without danger, the
weighing machine is to be immediately unplugged from the
electricity supply (pull out power adapter) and secured against
inadvertent operation.

In carrying out maintenance work, it is essential to follow the
recommendations in Chapter 6 Maintenance and service.

The weighing machine must not be operated in an area
subject to explosion risks.

Care must be taken when weighing liquids to ensure that no
liquid is spilled into the inside of the weighing machine or into
connections on the rear of the equipment or the power
adapter. If liquid is spilled on the weighing machine, it must
immediately be unplugged from the mains electricity supply
(pull out power adapter).

The weighing machine may only be operated again after it has
first been re-checked by a service technician.

These operating instructions must be read by each operator of
the equipment and must be available at the workplace at all
times.
