11. The engine cannot be started. When the loader’s engine cannot be started, the possible reasons are:
(1) Fuel problem:
Check whether the fuel is sufficient and eliminate oil leakage problems in the fuel system.
(2) Battery problem:
Check whether the battery is charged and maintain good battery and wire connections.
(3) Ignition system problems:
Check whether the ignition system is normal and troubleshoot the ignition coil, candle wire, etc.
12. The walking track cannot move. When the walking track of the loader cannot move, the possible reasons are:
(1) Hydraulic system problems:
Check whether the oil level of the hydraulic system is normal, and also check whether there is oil leakage in the hydraulic pump, valves, etc.
(2) Track tightness problem:
Check whether the tension of the track is appropriate and adjust the tension in time.
(3) Electrical system problems:
Check whether the electrical system is normal and eliminate problems such as poor wire contact and short circuit.
13. The lifting arm cannot be raised. When the loader’s lifting arm cannot be raised, the possible reasons are:
(1) Hydraulic system problems:
Check whether the oil level of the hydraulic system is normal, and also check whether there is oil leakage in the hydraulic pump, valves, etc.
(2) Lifting arm hydraulic cylinder problem:
Check whether the hydraulic cylinder is normal and eliminate problems such as seal wear and internal failure of the hydraulic cylinder.
(3) Hydraulic system adjustment issues:
Check whether the adjustment of the hydraulic system is reasonable, and adjust the hydraulic system if necessary.
14. The joystick cannot be operated. When the loader’s joystick cannot be operated, the possible reasons are:
(1) Joystick hydraulic cylinder problem:
Check whether the hydraulic cylinder is normal and eliminate problems such as seal wear and internal failure of the hydraulic cylinder.
(2) Hydraulic system problems:
Check whether the oil level of the hydraulic system is normal, and also check whether there is oil leakage in the hydraulic pump, valves, etc.
(3) Joystick mechanical connection problem:
Check whether the mechanical connectors are loose and tighten them in time.
The malfunctions that may occur during the use of the loader mainly include the inability of the engine to start, the inability of the walking track to move, the inability to raise the lifting arm, and the inability to operate the joystick. For these faults, we can determine the cause of the fault by checking the normal operation of the fuel, battery, ignition system, hydraulic system, hydraulic cylinder and other components, and eliminate the problem in time. When operating a loader, you should also pay attention to regular inspection and maintenance of mechanical equipment to extend its service life and improve work efficiency.
As the working hours of loaders increase, many aging parts also need to be replaced in time. If you need to purchase loader parts, you can contact us. If you want to buy a second-hand loader, you can also contact us. CCMIE gives you the most comprehensive purchase assistance.
