先检查一下滑轨是否异位，有则进行适当调节。再检查一下滑槽是否破损或者年久生锈，有则涂抹适当的润滑油。如果还是无法解决或者自行无法处理，请装门的师傅处理。

　　First, check if the slide rail is out of place, and if so, make appropriate adjustments. Check again if the groove is damaged or rusted over time, and apply appropriate lubricating oil if there is. If it still cannot be resolved or cannot be handled by oneself, please ask the door installer to handle it.

　　大多是两边溜槽长期摩擦造成的。 建议更换溜槽。如果卷帘门正常卷起，则无需考虑卷帘门的弹簧是否损坏。 一般是卷帘门的百叶夹卡住导向槽或窗帘变形造成的。 注意下卷门的导槽进入导槽处是否有异常维修建议。

　　Most of them are caused by long-term friction between the two chutes. Suggest replacing the chute. If the rolling shutter door rolls up normally, there is no need to consider whether the spring of the rolling shutter door is damaged. Generally, it is caused by the blind clip of the rolling shutter door getting stuck in the guide groove or the deformation of the curtain. Pay attention to whether there are any abnormal repair suggestions at the entrance of the guide groove of the lower roll door.

　　要费好大的劲才可以拉，已经是顶上弹簧轮松了或坏了，加润滑油也不会改善很多。是请修卷闸门师傅看看处理。另外门很大的话一般下面有77个把手的，需要同时拉上。不协调拉上也会很费劲的。

　　It takes a lot of effort to pull, as the top spring wheel is already loose or damaged, and adding lubricating oil will not improve much. It's best to ask the gatekeeper to take a look and handle it. Additionally, if the door is large, there are usually two handles underneath that need to be pulled up simultaneously. It can also be very difficult to coordinate.

　　轨道内应经常清扫，以免杂物堆积影响运行。驱动器每年少要加注一次润滑脂，链条应经常加注润滑油，并检查各部件磨损情况，磨损严重的机件要及时维修或更换。

　　The track should be cleaned regularly to prevent the accumulation of debris from affecting operation. The driver should be lubricated at least once a year, and the chain should be regularly lubricated with oil. The wear of each component should be checked, and parts with severe wear should be repaired or replaced in a timely manner.

　　再有就是卷帘门上面的弹簧可能有一边坏了，导致方向不正，也会出现不好拉的情况。遇见上述情况，建议你先检查一下两边的滑槽，看看是否有坏损之处，然后拉一下门，看是不是门的方向偏了。

　　Another issue is that one side of the spring on the rolling shutter door may be damaged, causing the direction to be incorrect and making it difficult to pull. In the above situation, it is recommended that you first check the sliding grooves on both sides to see if there are any damages, and then pull the door to see if the direction of the door is off.

　　卷帘门拉不下来119会管。卷帘门如果拉不下来，那么很有可能是上面的卷帘部分被什么东西卡住了，可以先检查卷帘门是否有地方损坏，导致卡在轴上，可以先将损坏的部分进行压平，那么就可以先将卷帘门拉下来，然后再进行维修。

　　If the rolling shutter door cannot be pulled down, 119 will take care. If the rolling shutter door cannot be pulled down, it is very likely that the upper rolling shutter part is stuck by something. You can first check if there is any damage to the rolling shutter door that causes it to get stuck on the shaft. You can flatten the damaged part first, then you can pull down the rolling shutter door first, and then repair it.
