Information:

Problem 1
The hydraulic power is low.Probable Causes
Ensure that the engine is operating correctly.
The hydraulic oil is low. Check the hydraulic oil level.
The oil is not to the correct operating temperature. Check the oil temperature.
There is air bubbles in the oil.
The pilot oil pressure is low.
The maximum pump output pressure is low. Refer to "Problem 4".
The line relief valves are not set correctly.
Pilot control valves do not operate correctly.
The cylinders are leaking.Problem 2
None of the functions will operate or all of the functions operate slowly.Probable Causes
The operating mode switch is not in the WORKING MODE position. Place the operating mode switch in the WORKING MODE position.
There is a leak in the system. Visually inspect the system for leaks in the system.
The pilot oil pressure is low.
The high pressure cutoff of the piston pump (implement) for the work tool is not correct.
The standby pressure is not set correctly.
The line relief valves are not set correctly.
The inlet screen for the piston pump (implement) is dirty. Drain the hydraulic tank. Inspect the inlet screen for contamination.
The pilot control valves are not operating correctly.
The seals in the cylinders are leaking.
The implement valve is not operating correctly. Inspect the components of the valve for damage or for contamination.Problem 3
The pilot oil pressure is low.Probable Causes
The setting for the pressure reducing valve is not correct.
Check the operation of the pilot relief valve.

The flow compensator spring that is located in the piston pump (implement) control valve is damaged. Remove the spring and inspect the spring for damage.
The flow compensator spool has damage or the spool has contamination. Remove the spool and inspect the spool.Problem 6
A hydraulic circuit is hammering.Probable Causes
There is air in the system. Refer to "Problem 11".
You are not using the machine correctly.
The line relief valves are not set correctly.
The standby pressure is not correct.
The pilot pressure is not set correctly.Problem 7
You cannot lower the boom.Probable Causes
There is a loss in pilot pressure.
The spool cannot shift.
The boom lower solenoid has failed.Problem 8
You cannot raise the boom or you cannot lower the boom.Probable Causes
None of the other functions are operating correctly. Refer to "Problem 2".
The lift cylinder has damage. Replace the cylinder.
The mechanical linkage of the boom has damage. Repair the damage.
The pilot control valve is not working correctly.
There is a failure in one of the seals of the lift cylinder.
The main control spool is stuck. Disassemble the valve.
