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.
