　　Check if the spring is aging, has insufficient elasticity, or is broken. If there is a problem with the spring, it needs to be replaced with a new one.

　　调整弹簧拉力，确保闸杆重量与弹簧拉力匹配。

　　Adjust the spring tension to ensure that the weight of the brake lever matches the spring tension.

　　卷轴问题：

　　Scroll issue:

　　检查卷轴是否损坏，如轴体弯曲或轴承损坏，如果卷轴有问题，需要修复或更换卷轴。

　　四、控制器和遥控器问题

　　4、 Controller and remote control issues

　　控制器故障：

　　Controller malfunction:

　　检查控制器的电源连接是否正常。

　　Check if the power connection of the controller is normal.

　　检查控制器的内部电路是否有问题，如果控制器有问题，可能需要更换控制器。

　　Check if there is a problem with the internal circuit of the controller. If there is a problem with the controller, it may need to be replaced.

　　遥控器故障：

　　Remote control malfunction:

　　更换遥控器的电池，并检查电池与遥控器内部的接触点是否良好。

　　Replace the battery of the remote control and check if the contact points between the battery and the interior of the remote control are good.

　　如果更换电池后仍然无法使用，可能是遥控器内部损坏，需要维修或更换遥控器。

　　If the battery still cannot be used after replacement, it may be due to internal damage to the remote control and requires repair or replacement.

　　检查接收器是否有问题，如果接收器有问题，需要维修或更换接收器。

　　Check if there is a problem with the receiver. If there is a problem with the receiver, it needs to be repaired or replaced.

　　五、其他注意事项

　　5、 Other precautions

　　在进行卷帘门维修时，请确保已经断电，以避免触电风险。
