What to do if all functions are not operational on Hyundai Robex 22-7 Excavators?
If all functions of your Hyundai Excavators are not operational, the first step is to fill up with hydraulic oil. If the issue persists, it's possible that the pumps or couplings are faulty, requiring disassembly and inspection. In such cases, you may need to replace the pump assembly or couplings.
Why is the operation power weak on my Hyundai Excavators?
If your Hyundai Excavators are showing weak operational power, several factors could be at play. Start by checking the hydraulic oil level and replenishing it if necessary. Also, inspect the suction filter for any blockages and clean it. Other potential causes include a faulty intake system, which would require repairing the affected piping, or the presence of bubbles in the hydraulic oil, necessitating identification and removal of the bubble source. Low pump flow requires replacement of the pump assembly. If the hydraulic oil is deteriorated, replace it. Also ensure that the pressure is correct, and the relief valve is working correctly by cleaning, disassembling, adjusting or replacing it. Finally, a large internal leak on the control valve requires replacement of the assembly.
