Jinan rolling shutter doors are not uncommon in our lives. Now, they are not only used in factory garages, but also in many families. The rolling shutter door is driven by the rotation of the motor to rotate the transmission shaft, so as to realize the lifting of curtain sheet. When it rises, the curtain wraps around the reel, and when it descends, it slides down the guide rail. The rising, stopping and descending actions of the curtain are realized through the control of the remote controller. There is also a power failure manual release system, when the power failure, you can lift the rolling shutter door through the manual rocker.

如果出现上述情况，建议您检查两侧的滑槽，看看是否有损坏，然后拉打开门，看看门的方向是否偏离。如果滑槽或隐藏在滑槽中的门没有损坏，请润滑滑槽(因为润滑脂会持续更长时间)。如果还是不行，有可能是上面的弹簧坏了。

If the above situation occurs, it is recommended that you first check the chute on both sides to see if there is any damage, and then pull open the door to see if the direction of the door deviates. If the chute or the door hidden in the chute is not damaged, lubricate the chute (as the grease will last longer). If it still doesn't work, the spring on it may be broken.
