1. Check the spring

在上掀门上，每一面的弹簧都挂在槽中。将弹簧钩移至相邻的槽中，调整其弹力。在卷帘门上，每一面的弹簧均由滑轮上的弹簧式缆线控制。为了调整弹簧的弹力，请将经过门上方平板的缆线拉长，然后在末端重新打结，以保持新的弹力。警告：如果卷帘门只在门中央有一个扭转弹簧，请不要尝试修理它。因为那弹簧的弹力实在是太大了，可能会使您受伤。对于使用了这种弹簧的门，应当打电话向专业维修服务部门求助

On the raised door, the springs on each side are hung in the slots. Move the spring hook to the adjacent slot to adjust its force. On the roller shutter door, the springs on each side are controlled by a spring type cable on the pulley. To adjust the spring force, please elongate the cable passing through the flat plate above the door and then tie it back at the end to maintain the new force. Warning: If the roller shutter door only has a torsion spring in the center of the door, please do not attempt to repair it. Because the spring force is too strong, it may cause you injury. For doors that use this type of spring, you should call a professional repair service department for assistance

2.将所有变松的螺丝拧紧

2. Tighten all loose screws

请查找变松的部件，并根据需求上紧。在上掀门上，检查安装弹簧的平板，确保螺钉已经旋紧，并将变松的螺钉拧紧。在卷帘门上，请检查将门的各个部分固定在一起的铰链，将所有变松的螺钉拧紧，并更换受损的铰链。门有时向一侧下沉，这个问题往往可以通过维修铰链来纠正。如果螺钉孔变大了，请换一根直径相同但更长的螺钉，在一根空心纤维棒上涂木工胶，然后套在新螺钉上。如果铰链处的木料出现裂缝，请拆掉铰链，将木料填孔剂填在裂缝和螺钉孔中。待填孔剂干燥后再更换铰链。如果可能，请将铰链移到实心木料上。

Please search for loose components and tighten them as needed. On the raised door, check the flat plate where the spring is installed to ensure that the screws are tightened and tighten the loose screws. On the roller shutter door, please check the hinges that secure the various parts of the door together, tighten all loose screws, and replace the damaged hinges. Doors sometimes sink to one side, and this issue can often be corrected by repairing the hinges. If the screw hole becomes larger, please replace it with a screw with the same diameter but longer, apply woodworking adhesive to a hollow fiber rod, and then place it on the new screw. If there are cracks in the wood at the hinge, please remove the hinge and fill the cracks and screw holes with wood filler. Replace the hinge after the pore filling agent has dried. If possible, please move the hinge onto solid wood.

3.确保轨道是否在水平线上

3. Ensure that the track is on a 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，轨道的纵向部分应精确垂直。在车库的墙壁上，两条轨道必须处于同一高度，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 spirit level to ensure that it is on the same horizontal line. The horizontal track should tilt slightly towards the rear of the garage, and if it is a rolling shutter door, the longitudinal part of the track should be accurately vertical. On the wall of the garage, the two tracks must be at the same height. If the tracks are not accurately aligned, loosen the screws or bolts that secure the mounting bracket, but do not remove them. Then, carefully tap the tracks to move them to the appropriate position. Recheck the tracks with a spirit level to ensure they are in the correct position, and then tighten the screws or bolts on the mounting bracket.

4.检查金属轨道

4. Check the metal track

检查车库内部的金属轨道，查看将轨道固定到墙壁的安装支架。如果支架松了，请拧紧螺栓或螺钉。将车库门关上，在车库内部检查轨道是否有凹陷、弯曲或变平的地方，如果有任何损坏之处，请用橡皮锤，或用一块废木料垫着锤子敲打这些地方。如果轨道严重损坏，您必须更换。

Check the metal tracks inside the garage and check the mounting brackets that secure the tracks to the walls. If the bracket is loose, tighten the bolts or screws. Close the garage door and inspect the tracks inside the garage for any dents, bends, or flattened areas. If there is any damage, use a rubber hammer or use a piece of scrap wood to pad the hammer against these areas. If the track is severely damaged, you must replace it.

5.在轨道上喷洒润滑油

5. Spray lubricating oil on the track

将石墨粉撒在轨道上，将家用润滑油或硅树脂喷在转轴上，或者在轨道和转轴上喷洒车库门专用润滑油喷剂，以起到润滑作用。如果有滑轮，请您使用和用在转轴上的相同的润滑剂润滑。

Sprinkle graphite powder on the track, spray household lubricating oil or silicone resin on the shaft, or spray garage door specific lubricating oil spray on the track and shaft to provide lubrication. If there is a pulley, please use the same lubricant as used on the shaft for lubrication.

6.将轨道污垢去除干净

6. Remove track dirt thoroughly

用高浓度家用清洁剂清洗轨道，去除污垢和硬化的油脂。将转轴彻底清洗干净，然后将轨道和转轴擦干。

Clean the track with a high concentration household cleaner to remove dirt and hardened grease. Thoroughly clean the shaft and then wipe the track and shaft dry.
