4. Test by replacing the port relief valve
Replace the port relief valve in question with a port re-
lief valve used for a normal boom. If the bucket cylinder
operates normally with the replacement valve, the port
relief valve used on the bucket side is faulty.
5. Check the bucket cylinder
Switch between the arm hose and the bucket hose
