If the spring of the rolling shutter door is broken, the only way to repair it is to replace it with a new one. After buying it, you can install it in place by following the correct steps.
1. First, you need to grasp the spring shell with your hand, facing the direction of the person, and hold it upward. With the other hand, fix the screw on the door body so that it cannot become loose, and then use a wrench to remove it.
2. There are two screws on both sides of the rolling shutter door. They must also be removed and then remove the screws. Next, you need to connect the newly purchased spring jacket, fix the screws, and then tighten the spring. This step is very critical.
3. After tightening, the step of replacing the spring is basically completed. If you are not particularly familiar with it, you can ask professional technicians to come to repair it, because when you repair it yourself, you may be easily injured due to the relatively strong force of the spring.
