Extract from the Service Manual:

1. Check the load check valve on the control valve.
a. Disconnect the hose connecting the control valve and the arm cylinder from the control valve.
b. Connect the hose just disconnected to the bucket block.
c. Move the lever (bucket) to operate the arm cylinder.

If the arm cylinder operates normally, the load check valve (1) must be faulty.
Before starting the work above, lower the lift arm and bring the bucket down to the ground.
When the spool first draws, the oil pressure is low and the flow rate is small. Therefore, if the load check valve is faulty, the oil temporarily flows backward due to the load applied to the arm cylinder. As a result, the lift arm temporarily drops.

2. Check for leak inside the arm cylinder.
If the oil is flowing from the head side (A) to the rod side (B) due to the faulty arm cylinder piston or the tube, the lift arm temporarily drops because of the low oil pressure and small flow rate at the beginning of the spool drawing. Also, the cylinder has insufficient drive power.
However, the amount of spontaneous drop is large in this case.
