As a door accessory, the door closer is basically used multiple times a day; problems are prone to occur if you do not maintain it for a long time!
common problem:
1. The installation screw is loose or dropped, and the installation error of the door closer may be caused by the door closer falling, and the connecting arm is forced to separate and damage the door closer!
2. If the door closer is used for a long time, the performance will be deteriorated and the effect will be weakened. When the fire door is closed, the speed and force of the buffer becomes uncontrollable, which will cause secondary damage to the fire door. Cause deformation!
3. Oil leakage, this is also the most important part of door closer products; most of our owners do not pay too much attention to the oil leakage of the door closer, which is caused by insufficient understanding of the door closer. We can understand that the door closer itself is a sealed product. The occurrence of oil leakage proves that the part of the product leaks and leaks, which is no better than any of our other products. Only its internal problems can cause oil leakage! If the above problems occur, the door closers can only be returned to the manufacturer for after-sales or directly updated, because the leaking door closers will no longer be of any use at all. If the door closer cannot be used in the event of a fire, then we will have a lot less chance of escape!
Pay attention to the maintenance of door closer products to better protect the health of our family
