Frequently Asked Questions
What to do if the hydraulic system pressure is low?
Check the hydraulic pump, pressure control valve, and hydraulic cylinders. Test the hydraulic oil for contamination or degradation, clean or replace relevant components, and ensure the hydraulic system is properly sealed.
What are the reasons why the excavator can rotate when starting, but cannot start?
1.There is no oil in the fuel tank.
2.The fuel filter and oil-water separator are blocked.
3.The low-pressure oil circuit does not supply oil.
4.The injection pump does not pump oil.
5.There is air in the oil circuit.
6.The valve timing is misaligned. The opening time of the valve is not coordinated with the stroke of the piston in the cylinder. For example, when the piston makes a compression stroke in the cylinder, the intake and exhaust valves are open, and fresh air is driven out of the cylinder, so that there is no combustion gas in the cylinder and it cannot start.
7.The solenoid valve of the injection pump is broken and is in a closed state, and the diesel cannot enter the high-pressure chamber.
Why does the hydraulic system overheat during excavation?
Possible low hydraulic oil level, clogged filter, excessive load, or cooling system failure. Solution: Check and refill hydraulic oil, clean or replace filter, reduce system load, check and repair cooling system.
What to do if the excavator has an oil leak?
To address oil leaks, inspect seals, fittings, and lines. Locate the leak, tighten any loose fittings, and replace worn or damaged seals and lines. Clean the area and recheck for leaks.
