In this video, we walk through hydraulic pressure testing and adjustment on an AGT 1-ton Chinese mini excavator, specifically the AGT WH12R mini excavator, to find the optimum hydraulic pressure setting. We also field test various pressures - both high and low - to see how the machine responds.
If you own, operate, or are thinking about buying a Chinese mini excavator, this video will help you understand how to properly test hydraulic pressure, adjust relief valves, and fine-tune hydraulic performance for real-world work.
What is the perfect hydraulic pressure for a 1-ton Chinese mini excavator? It's hard to find a definitive answer for this. We discover the optimum setting (for my machine) HERE! That's why you should watch this video!
The steps in this process should be similar for comparable AGT 12-series Mini Excavators like the AGT H12, AGT QH12, AGT MX12, AGT L12, and so on.
