1. You can put the sliding door flat on the cardboard floor. If the intensity is high, there is no need to fall down. You can directly support the sliding door vertically on the ground, or you can omit cardboard and a small floor.
2. Observe the wool at one end of the sliding door frame, some directly stick to the door frame, some stick to the door frame, and then insert the screw from the hole.
Just pull the wool out of the hole and then pull it out again.
4. The bottom screw hole is the screw hole for fixing the sliding door pulley (the hole needed for disassembling the sliding door pulley), and the screw hole for fixing the aluminum alloy frame is above it.
5. Then close the screw hole. As can be seen from the photo, the hexagon screw is rusted and the screw for fixing the door frame is intact.
6. Press the pulley of the sliding door with one hand so that the hexagon socket head screw faces the screw hole, insert the hexagon head screw hole from the screw hole at the bottom with the other hand, and then unscrew the hexagon head screw counterclockwise.
7. Finally, pull out the pulley and remove the sliding door pulley.
8. If the pulley is rusty, see if you can put some butter on it. If not, change the pulley. There are generally two kinds of wheels for sliding doors: 70 and 80. Just tear down the old one and buy the same one.

Maintenance of aluminum alloy sliding door;
1. When using aluminum alloy sliding doors, the movements should be light and the push-pull should be natural.
2. If you find it difficult, don't push it hard, solve problems first; Dust accumulation and deformation are the main reasons for the difficulty in pushing and pulling aluminum alloy sliding doors. Keep the door frame clean, especially the chute clean. Dust accumulated in the groove and top of the door sealing strip can be sucked away by vacuum cleaner.
3. The friction of the chute increases after being used for a long time, and you can add a little engine oil or a layer of wax oil.
4. Always check the connecting parts of aluminum alloy sliding doors and replace the damaged parts.
5. Sealing roof and glass glue seal are the key structures to ensure the sealing and thermal insulation of doors and windows. If it falls off, it should be repaired and replaced in time.
6. Always check the joint of aluminum alloy sliding door wall. If it is loose for a long time, it is easy to deform the whole frame and make the door unable to close.
