for the clam bucket, the cycle times for the backhoe extendable stick or the cycle times for the auxiliary hydraulics are too slow.
The swing cycle times are too slow.
The swing cycle times are too fast.
The cycle times for the stabilizer LOWER are too fast.
The cycle times for the stabilizer are too slow.
The stabilizers will not lower the machine.
The swing cylinders hit the swing stops hard. Problem 1The temperature of the oil is too hot.Possible Causes
The oil level in the hydraulic tank is too low.
The viscosity of the oil is wrong or the wrong oil is used.
The pump is worn.
There is a restriction in flow due to a bent hose, a bent tube, or a restriction in an oil passage.
The load that is on the system is too high.
There is air in a hydraulic circuit.
There is a restriction to the flow of air through the oil cooler.
The outside air temperature is too hot.
The work tools are operated too long.
The piston seal on the pump is worn. Problem 2The pump makes unusual noise and the cylinder rods do not move smoothly.Possible Causes
There is cavitation due to atmospheric low pressure.
The oil level in the hydraulic tank is too low.
The viscosity of the oil is wrong.
There is a loose connection on the inlet side of pump or the tube on the pump outlet is bent.
The pump rotating group is worn.
There is air in a hydraulic circuit. Problem 3A large amount of air is in the oil.Possible Causes
There is a loose connection on the inlet side of pump.
The hydraulic system was not purged of air after assembly, inspection, or testing.
There is leakage in the cylinder seals and around the cylinder seals.
Check for loose fittings or cracked fittings.
The oil level is low.
There is aeration in the tank. Problem 4The pump standby pressure is too low.Possible Causes
The pressure compensator is set too low.
The spring for the pressure compensator in the pump is broken.
The pump is not upstroking. The swashplate is blocked or the actuator spring is broken.
The signal network is blocked. Problem 5Pump standby pressure is too high.Possible Causes
The flow compensator is set too high.
The flow compensator is not moving.
The pump is not destroking. The actuator piston is stuck or the swashplate is blocked. Problem 6There is a pause before the pressure is reached in all circuits.Possible Causes
The margin pressure is low.
There is air in the signal network.
There is leakage in the signal network.
An orifice is slightly plugged in the signal network.
There is an incorrect orifice in the signal network. Problem 7Any of the implements move, when the control lever is in the HOLD position. Possible Causes
The pilot control valve (if equipped) is stuck open.
The control valve spool or the bore for the valve spool may be worn excessively. This may cause leaks.
There is leakage in the seals and around the seals of the piston in the cylinders that are affected.
There is a leak in the lines between the control valve and the cylinders.
The solenoid for the multipurpose bucket has current and the solenoid has
