先檢查一下滑軌是否異位，有則進行適當調節。再檢查一下滑槽是否破損或者年久生銹，有則涂抹適當的潤滑油。如果還是無法解決或者自行無法處理，請裝門的師傅處理。

　　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.

　　大多是兩邊溜槽長期摩擦造成的。 建議更換溜槽。如果卷簾門正常卷起，則無需考慮卷簾門的彈簧是否損壞。 一般是卷簾門的百葉夾卡住導向槽或窗簾變形造成的。 注意下卷門的導槽進入導槽處是否有異常維修建議。

　　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.

　　要費好大的勁才可以拉，已經是頂上彈簧輪松了或壞了，加潤滑油也不會改善很多。是請修卷閘門師傅看看處理。另外門很大的話一般下面有2個把手的，需要同時拉上。不協調拉上也會很費勁的。

　　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.

　　軌道內應經常清掃，以免雜物堆積影響運行。驅動器每年少要加注一次潤滑脂，鏈條應經常加注潤滑油，并檢查各部件磨損情況，磨損嚴重的機件要及時維修或更換。

　　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.

　　再有就是卷簾門上面的彈簧可能有一邊壞了，導致方向不正，也會出現不好拉的情況。遇見上述情況，建議你先檢查一下兩邊的滑槽，看看是否有壞損之處，然后拉一下門，看是不是門的方向偏了。

　　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.

　　卷簾門拉不下來119會管。卷簾門如果拉不下來，那么很有可能是上面的卷簾部分被什么東西卡住了，可以先檢查卷簾門是否有地方損壞，導致卡在軸上，可以先將損壞的部分進行壓平，那么就可以先將卷簾門拉下來，然后再進行維修。

　　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.
