How is the ultimate load controller of a lawn mower working?

Practically operate the arm joystick to extend the arm; Turn the control button to position 0, actually operate the operating handle, and observe the fitness exercise rate of the operating handle. At this point, the P3 ¡÷ P of the detector should be 25bar; Has the control button slowed down the lever movement rate, ¦¤ Has P's work pressure value decreased. If that's the case, the actual operation of the limit load controller is normal. That is, for electronic device boxes, the operation of the pump is normal. Remove the wiring of the extreme load pressure measurement point, tighten the measurement point cover, and connect the working pressure of the detector into the port number line to the plug-in pressure measurement point; The speed of the car should be in low gear (should be 1000-1200rpm), and the plug-in working pressure should be loaded from the detector by pressing the foot pedal (forward or backward). If it is not suitable, it should be 25-27bar. On the driving foot pedal, adjust the upper adjustment screw of the directional valve block.

When adjusting, loosen the nut first, and then adjust the adjusting screw. The clockwise value increases, the adjustment value in the opposite direction decreases, the actual operating arm rises and decreases, and the emergency actual operating pressure is loaded, which should be 14 bar. If not, please adjust the pressure regulating valve screw on the side of the energy accumulator to adjust the working pressure to 14bar. Subsequently, rotate the joystick in the opposite direction to all normal actual operating positions. The speed of the car is low (should be between 1000-1200rpm); Tighten the upper valve of the gas cylinder valve and quickly adjust the screw.

The working condition of the lawn mower load controller is like this, and I look forward to assisting you.
