Why is the hydraulic oil temperature rising too fast in my SUNWARD Excavator?
- TthompsonwilliamAug 15, 2025
If the hydraulic oil temperature in your SUNWARD Excavator rises too fast or becomes too high, it could be due to dirt on the surface of the oil cooler. Try cleaning the oil cooler. Another cause can be wear of hydraulic parts and reduction of the cubage efficiency, in this case you should contact the dealer. Also, check if the overflow valve and overload valve are opening too frequently. If so, avoid over digging or overloading, and consider changing your digging method.
