   The securing clamp (2a) must not be pushed straight over the connector (2). Otherwise this would be overstretched and a correct sealing of the line connection can no longer be assured.

   Attach transmission oil line to connector 

   The dust cap (3) must be replaced after every disconnection of a transmission oil line (1).

5. Push dust cap (3) onto the transmission oil line (1).
6. Introduce transmission oil line (1) straight into the connector (2) until it audibly and noticeable latches.
7. Push dust cap (3) onto connector (2).

   If the dust cap (3) cannot be pushed over the connecting point then the transmission oil line (1) is not fully latched in the connector (2) or the safety clamp (2a) is overstretched.
