Extract from the Service Manual:
Inspect the swivel joint.
Disconnect the hose between the swivel joint and the counterbalance valve from the counterbalance valve side and set a pressure gauge
in the hose.
Operate the travel lever and measure the pressure.
The swivel joint is normal if the pressure gauge reading indicates the standard value.
Standard value: Approx. 27.5 MPa
Inspect the counterbalance valve.
If neither forward nor reverse travel is possible, the spool (1) of the counterbalance valve could be sticking in the neutral position.
If either forward or reverse travel is possible, the spool (1) of the counterbalance valve could be sticking in a position other than the neutral position.
Disconnect the counterbalance valve plug (2) and try pushing the spool (1) with a finger. It is normal if it moves smoothly about 6 mm.
