On the top lift door, check the flat plate with spring, make sure that the screw has been tightened, and tighten the loose screw. On roller shutter doors, check the hinges that hold the various parts of the door together, tighten all loose screws, and replace the damaged hinges. Sometimes the door sinks to one side, which can be corrected by repairing the hinge. If the screw hole becomes larger, replace it with a screw of the same diameter but longer, apply wood glue to a hollow fiber rod, and then put it on the new screw. If there are cracks in the wood at the hinge, remove the hinge and fill the cracks and screw holes with wood filler. Replace the hinge after the filler is dry. If possible, move the hinge onto the solid wood.
3.确保轨道是否在水平线上
3. Make sure the track is on the horizontal line
用水平仪检查轨道，确保轨道在同一水平线上。水平轨道应当略向车库后部倾斜，如果是卷帘门，轨道的纵向部分应垂直。在车库的墙壁上，两条轨道处于同一高度，如果轨道没有准确对齐，请将固定安装支架的螺钉或螺栓拧松，但不要把它们取下来，然后小心地敲打轨道，使它们移动到适当的位置。用水平仪重新检查轨道，确保它们处于正确的位置，然后将安装支架上的螺钉或螺栓拧紧。
Check the track with a level gauge to ensure that the track is on the same horizontal line. The horizontal track should be slightly inclined to the rear of the garage. In case of rolling shutter, the longitudinal part of the track should be vertical. On the wall of the garage, the two rails are at the same height. If the rails are not aligned accurately, please loosen the screws or bolts that fix the mounting bracket, but do not take them off, and then knock the rails carefully to make them move to the appropriate position. Recheck the tracks with a level to make sure they are in the correct position, and then tighten the screws or bolts on the mounting bracket.
