8.3 Installation of the Gyrosphere

8.3.1

Installing the Gyrosphere in the Gyrosphere Container

At the place of installation, a clean and level work surface must be available.

Parts and tools required

–

the installation and replacement parts kit, stock no. 074696

–

a 4 mm Allen key

–

a lint-free cloth for cleaning purposes

Procedure

Remove the gyrosphere container from
its transport box and place it on the work
surface.

Disconnect the connector from the
centering pin, unscrew the pin and place
it aside (do not yet remove the protective
cap from the pin).

Disconnect the plug connector from the
base contact.

Unscrew the 4mm Allen-head screws at-
taching the two halves of the gyro-
sphere container.

Put the screws and washers aside, mak-
ing sure they won't be lost or fall to the
ground.
