7.1.1 Emergency lid release
In the event of a power failure, it is possible to manually open the
centrifuge lid with a socket spanner (part no. 930 014, included in the scope
of supply). The opening is located in the base plate in the front quarter on
the left-hand side.
• Switch the centrifuge off by actuating the mains power switch and by
unplugging the mains power plug.
• Pull the centrifuge a bit over the edge of the table and jack it up (e.g. on
two wooden logs). Ensure that the centre of gravity of the centrifuge is
still located above the table top. If necessary, the unit must be secured
by a second person.
• Insert the spanner for the emergency release into the hole (see the
illustration, item 1) and attach it to the shaft of the lid lock motor.
• Turn the shaft carefully clockwise with the aid of the wrench until the lid
opens.
• Remove the spanner and pull the centrifuge back on the table.

WARNING
Do not unlock the lid unless the rotor is at a standstill and unless there is
no danger to other persons!
If the lid is opened via the emergency lid release during a centrifuge run,
the centrifuge will be switched off immediately and decelerate in a brake-
less manner.
As a general rule, the lock can be opened more easily with the emergency
lid release system if the load on it is relieved by exerting slight pressure on
the lid.
