Now, with the development of automobile manufacturing industry, private cars are more and more. After people have a car, they will build a small garage at home to put their own cars. When building a garage, they need to install the garage door. In order to use the garage door longer, what should be done to prolong its service life. Here are some suggestions for this issue.

1、在轨道上喷洒润滑油：

1. Spray lubricating oil on the track:

在轨道上撒上石墨粉，在转轴上喷涂家用润滑油或硅树脂，或在轨道和转轴上喷涂车库门专用润滑油进行润滑。如果有皮带轮，请使用旋转轴上使用的相同润滑剂进行润滑。

Sprinkle graphite powder on the track, spray household lubricating oil or silicone resin on the rotating shaft, or spray special lubricating oil for garage door on the track and shaft for lubrication. If there is a pulley, lubricate it with the same lubricant that is used on the rotating shaft.

2.拧紧所有松动的螺钉：

2. Tighten all loose screws:

请找到松动的零件，并按要求拧紧。在上部电梯门上，检查安装有弹簧的平板，确保螺钉已经拧紧，并拧紧松动的螺钉。在卷帘门上，请检查将所有松动螺钉固定在一起的铰链，并更换损坏的铰链。门有时会向一边下沉，这通常可以通过修理铰链来纠正。如果螺丝孔变大，请更换相同直径但更长的螺丝，并在中空纤维棒上涂上木工胶。然后把它放在一个新的螺丝钉上。如果铰链处的木头有裂缝，请取下铰链，在裂缝和螺丝孔中填充填孔剂，并在填孔剂干燥后更换铰链。如果可能，请将铰链移到实木上。

Please find the loose parts and tighten them as required. On the upper elevator door, check the spring mounted flat plate to ensure that the screws are tight and tighten the loose screws. On roller shutter doors, check the hinges that hold all loose screws together and replace damaged hinges. Doors sometimes sink to one side, which can usually be corrected by fixing the hinges. If the screw hole becomes larger, replace the screw with the same diameter but longer, and coat the hollow fiber rod with wood glue. Then put it on a new screw. If there are cracks in the wood at the hinge, remove the hinge, fill the crack and screw hole with pore filling agent, and replace the hinge after the filler is dry. If possible, move the hinge to the solid wood.

3.检查弹簧：

3. Check the spring:

在上部电梯门上，每一侧的弹簧悬挂在凹槽中，弹簧钩移动到相邻的凹槽中以调节其弹性。在卷帘门上，两侧的弹簧由滑轮上的弹簧式缆线控制。为了调整弹簧的弹性，请加长穿过门上方板的缆线，然后在末端重新打结以保持新的弹性。如果卷帘门的中间只有一个扭转弹簧，请不要试图修理它，因为弹簧的弹性太大，可能会导致你受伤。对于使用这种弹簧的门，你应该打电话给维修服务部门寻求帮助。

On the upper elevator door, the springs on each side are suspended in the groove, and the spring hook moves into the adjacent groove to adjust its elasticity. On the rolling shutter door, the springs on both sides are controlled by spring type cables on the pulley. In order to adjust the spring elasticity, lengthen the cable through the panel above the door, and then tie the knot again at the end to maintain the new elasticity. If there is only one torsion spring in the middle of the rolling shutter door, please do not try to repair it, because the spring is too elastic and may cause you to be injured. For doors that use this spring, you should call the service department for help.

4.清洁轨道污垢：

4. Clean track dirt:

用高浓度家用清洁剂清洁履带，污垢和硬化油脂，清洁转轴，然后干燥履带和转轴。

Clean the track with a high concentration of household detergent, remove dirt and hardened grease, clean the rotor shaft, and then dry the track and shaft.

5、检查金属轨道：

5. Check metal track:

检查车库内的金属轨道，并检查将轨道固定到墙上的安装支架。如果支架松动，请拧紧螺栓或螺钉并关闭车库门。检查车库内的轨道是否有凹痕、弯曲或变平的地方。如果有任何损坏，请用橡皮锤或废木垫锤敲击这些地方。如果履带严重损坏，你一定得更换它。

Check the metal rails in the garage and check the mounting brackets that hold the rails to the wall. If the bracket is loose, tighten the bolts or screws and close the garage door. Check the track in the garage for dents, bends or flattening. If there is any damage, tap these places with a rubber hammer or a waste wood cushion hammer. If the track is seriously damaged, you must replace it.

6.确保轨道在水平线上：

6. Make sure the track is on the horizontal line:

用水平仪检查轨道，确保它们在同一水平线上。水平轨道应该稍微倾斜到车库的后面。如果是卷帘门，轨道的纵向部分应该完全垂直。在车库的墙上，两条轨道一定要在同一高度。如果导轨没有准确对齐，请松开固定安装支架的螺钉或螺栓，但不要取下它们。然后小心敲打履带，将它们移动到正确的位置。用水平仪重新检查轨道，确保它们在正确的位置。

Check the tracks with a level to make sure they are on the same level. The horizontal track should tilt slightly to the back of the garage. In the case of rolling shutter doors, the longitudinal part of the track should be completely vertical. On the garage wall, the two tracks must be at the same height. If the rails are not aligned correctly, loosen the screws or bolts that secure the mounting bracket, but do not remove them. Then carefully tap the tracks to move them into the correct position. Recheck the tracks with a level to make sure they are in the correct position.
