When opening or closing a roller shutter door, check carefully for any objects in the way, especially for fireproof roller doors that are connected to the fire protection system. Improper operation often leads to damage or tilting of the fireproof roller door.
Ordinary electric roller shutter doors should also be given special attention. The door curtain should be operated with someone present on site, and in the event that the curtain tilts or the track gets stuck, the opening or closing should be stopped promptly to prevent further damage to the motor and the door curtain.
While the door curtain is opening or closing, pedestrians and running are strictly prohibited because the curtain is connected in panels, and the motor and transmission shaft also have minimal safety risks. Therefore, when the door curtain starts moving, people should try not to run.
