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.

In our daily life, we often encounter the problem that Jinan roller shutter door can not be put down or pushed upward. Most of the reasons for this situation are the long-term friction between the two sides of the chute, and some parts may be damaged, so the pulling is not very good. Then it is possible that one side of the spring on the shutter door is broken, resulting in wrong direction and poor pull

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.
