Extract from the Service Manual:

4. Inspect the relief valve.
a. Set a pressure gauge in the pressure sensor port.
b. Operate the operation lever corresponding to the hydraulic system for that relief valve.
c. The valve is normal if the pressure gauge reading is the standard value.
(Refer to “II, Specifications, Standards for Judging Performance”.)
I f the relief valve’s set pressure is too low, adjust it by tightening the relief valve set screw gradually.
Caution
If the pressure doesn’t rise after 1/4 turn of the screw, the relief valve is faulty.

Cautions During Disassembly and Reassembly The dimension A of the set screw should be measured and recorded when the cap nut is removed.
• Inspect for biting of foreign matter and for scratches in the poppet seat surface.

• During assembly, the set screw should be set so that dimension A , measured before disassembly, is a little longer than previously. Then the screw should be tightened gradually to adjust the pressure.
