A few buttons for lifting and lowering suddenly failed, what s going on

If the phone keys are not working, it is recommended that you do it:

1.If you cannot use the back button to go back to the previous interface or exit when running a program, it is recommended to click the home button to return to the standby interface and try to re-enter the program.

2.Turn off your phone and restart it.

3.If the back button, menu button, recent application button, and home button of your phone are not available, it is recommended to uninstall and delete the recently installed software.

If the problem persists, it may be a problem with the internal hardware, it is recommended that you bring the three-pack certificate of the mobile phone and send the mobile phone to the nearest Samsung service center for the engineer to check the machine.

Summary. 1. The lifting equipment does not need electrical energy during the descending process, in fact, it uses its own gravity to descend, and it can be lowered by pressing the 'descending' button directly.

2. Check whether the external power supply is connected normally, and the equipment cannot rise when there is no power.

3. Check whether the electrical switch of the elevator is connected or has poor contact, if everything is in good condition, you can eliminate the problem of the electrical system. If you find a problem with the electrical appliance, you can repair it.

4. If the solenoid valve is stuck, the button will also fail. If there is a problem with the solenoid valve, you can press the ejector rod of the solenoid to make the lift table completely lowered, and then clean and replace the solenoid valve.

5. The oil pipe is blocked, check whether the oil pipe permeability is good, and Xiongda Machinery reminds everyone to use high-quality hydraulic oil as much as possible.

The elevator is half up and the person below the elevator presses and stops, and the upper button fails.
