hello friend. I always follow your videos on Komatsu excavators series 5. I would like to know if you have video calibration of NC valves? our Excavator does not exceed 290 kgf p1 and p2. and the arm is weighing on the engine.
@@THIAGO_ELETRICISTA Have you checked the differential pressure at the jet sensors? If you have that 300 PSI difference between the jet sensor hoses at the bottom of the main valve sections, you can adjust the NC valves on the pump to get about 70 PSI of servo pressure when all the functions are in neutral. The next setting to check are the cut outs (CO Pressure). As you raise the pressure on a function, the pump output flow will decrease as shown on the pump servo pressure reading. When full destroyed, the servo pressure should also read about 70 PSI at your main relief valve pressure reading. Check out this video for the set up. ua-cam.com/video/XJHrU9ZsmEc/v-deo.html Good Luck!
How to adjust the flow rate of the attachment? Plese show the VDO.
Tanx a lot..
You are most welcome

Hello.. Do you have Zx210-5B wiring diagram.. Error code description
I'm sorry I don't have either. Thanks for asking the question.
Need to Kobelco Mark 10
