For version with a through drive, metallic
protective cover and mounting bolts

Ports intended for connecting lines are provided with protective plugs or
threaded plugs, which serve as transport protection. All of the ports required for
functional operation must be connected (see Table 12 “A4V ports Series 3x” on
page 51). Failure to do so could lead to malfunctions or damage. If a port is not
connected, it must be plugged with a threaded plug because protective plugs are
not pressure-resistant.

3.

For versions with a through drive, assemble the auxiliary pump according to the
pump manufacturer's instructions.
