Extract from the Service Manual

When the control lever is pulled slowly, the boom may temporarily drop. Follow these diagnostic steps:

1. Check the load check valve in the control valve:
   • Disconnect the control valve end of the hose from the boom cylinder.
   • Connect it to the arm or bucket block and operate the boom cylinder.
   • If the boom operates normally, the load check valve is likely faulty.
2. Inspect for leakage inside the boom cylinder:
   • Oil flowing from end A to end B may indicate a faulty piston or tube.
   • This can lead to reduced drive force and significant spontaneous drop.
   • Consult section 5 on Troubleshooting for further diagnostics.
