Precautions for floor spring maintenance
1. If the closing speed is too fast, adjust the speed control button in time. If there is no response, check whether the floor spring is leaking. If there is an oil leak, please replace it in time.
2. If the floor spring is found to be leaking, it should be replaced in time, please do not continue to use it because of hidden dangers.
3. The door leaf is only open in one direction. Any man-made closing action will cause damage to the internal components and cause one-way opening or damage. Therefore, it is better to automatically return and close the door.
4. The two door leaves are misaligned. Check whether the bottom spring box is fixed on the concrete floor, and adjust the up, down, front, and rear, left, and right adjustment buttons.
