7.7.4 Use of the external tank port (T)
Damage to the safety valve!
When installing hydraulic lines and hoses under pressure, they are exposed to
additional mechanical forces during operation, which reduces the life cycle of the
safety valve and the complete machine or system.
Assemble lines and hoses without stress.

Optionally, there is the possibility to use the external tank port (T)
(see element 1, fig. 3) instead of the internal pilot oil channel
1. Depressurize the relevant system part. Connect your line at the tank port T
observing the operating instructions of the system. The connection values are
specified in table 12 "Connection thread for optional T port".
