Page 367
Troubleshooting SY115C9/135C/155H Crawler Hydraulic Excavator 6) Has the same kind of failure occurred before? 3. Check before troubleshooting 1) Check the oil level. 2) Check for any external leakage of oil from the piping or hydraulic equipment. 3) Check the travel of the control levers.
SY115C9/135C/155H Crawler Hydraulic Excavator Troubleshooting 3) Investigate other related parts or information. 6. Measures to remove root cause of failure ★ Even if the failure is repaired, if the root cause of the failure is not repaired, the same failure will occur again. To prevent this, always investigate why the problem occurred.
Troubleshooting SY115C9/135C/155H Crawler Hydraulic Excavator 6.1.5 Hydraulic components handling precautions With the increase in pressure and precision of hydraulic equipment, the most common cause of failure is dirt (foreign material) in the hydraulic circuit. When adding hydraulic oil, or when disassembling or assembling hydraulic equipment, it is necessary to be particularly careful.
Page 370
SY115C9/135C/155H Crawler Hydraulic Excavator Troubleshooting 4. Change hydraulic oil when the temperature is high. When hydraulic oil or other oil is warm, it flows easily. In addition, the sludge can also be drained out easily from the circuit together with the oil, so it is best to change the oil when it is still warm.
