the cargador telescopico battery voltage of the loader is too low or the wires are damaged, the engine cannot start. At this point, it is necessary to check whether the battery voltage, wires, and fuses are normal.
Fuel system issues
telescopic loader weak or no action of the boom; The bucket flips slowly, weakly, or without any movement. The diesel forklift telescopic main cause of the two malfunctions is low working oil pressure, and the main reasons for low pressure are blockage and leakage. Smooth oil circuit and good sealing are the guarantees for the normal operation of the system. Blockage and leakage are the most common hydraulic transmission faults, so the inspection of hydraulic transmission faults generally starts from the hydraulic oil circuit.

Diagnosis and elimination of hydraulic system faults in working devices
When the loader and bucket are fully loaded, the lifting time of the boom should be less than 7 seconds at the rated engine speed, and the forward tilting time of the bucket should be less than 2.5 seconds. If it exceeds the corresponding time, it is considered slow action; The set pressure of the hydraulic system of the working device is 17Mpa. If it is lower than this pressure, it means that the system pressure is too low. The faults of the hydraulic system of the working device are mainly manifested in two aspects: slow lifting,
The shenzhen winston loader following are diagnostic and troubleshooting methods for 2.5 ton telescopic loader different fault phenomena in the hydraulic system of the working device.
Fault phenomenon: The schacman f3000 lifting of the boom is slow, weak or inactive, while the flipping of the bucket is normal in the hydraulic system of the working device. If only the lifting of the boom is slow, weak or inactive, while the 2.5t teleskoplader flipping of the bucket is normal. It is not difficult to see from the working principle diagram that the rotary bucket is working normally, which indicates that the working pump and the main safety valve are working normally, and the mini excavator sany pressure they provide to the entire system is sufficient. At the same time, it also indicates that the pipeline and oil filter at the pump inlet end, as well as the oil volume and quality in the oil tank, are not a problem. At this point, it is only necessary to check the boom slide valve, boom cylinder, oil pipe of the boom section, and their seals.
If the fuel filter or fuel pump of the loader malfunctions, the fuel supply will be affected, resulting in the engine being unable to start. The solution is to check whether the fuel filter and fuel pump are working properly, and remove any obstacles that may block the fuel pipeline. www.haiqinmachinery.com
