The motor of rolling shutter door can be seen on the top of the door. There are two hexagon adjusting inner hexagon nuts on the upper part and the lower part of the motor. There are up and down, left and right marks on the edge of the inner hexagon nut. The height of rolling shutter door can be adjusted by this position limiting adjuster.

分別按照調整器標識指示方向，調整卷簾門的調節方向，箭頭指示方向就是門體的運行方向。在標識一側有正和負的符號，此兩個符號代表卷簾門調節行程的大小。通過內六角扳手即可調整卷簾門位置高低。

Adjust the adjustment direction of the rolling shutter door according to the direction indicated by the regulator logo. The direction indicated by the arrow is the running direction of the door body. There are positive and negative symbols on one side of the sign, which represent the adjustment stroke of the rolling shutter door. The position of the rolling shutter door can be adjusted by the inner hexagon wrench.

電動卷簾門的保養知識：

Maintenance knowledge of electric rolling shutter door:

1、在電動卷簾門的使用過程中，要盡量保持控制器和電壓的穩定，禁止安裝在非常潮濕的環境，另外不要隨意打開遙控器，如若發現門體上有電線纏繞、打結等應及時處理。注意通道的是否堵塞，阻礙門體下降，如若發生異響應立即停止電機運作。

1. In the process of using the electric rolling shutter door, it is necessary to keep the controller and voltage stable as far as possible. It is forbidden to install it in a very humid environment. In addition, it is not allowed to open the remote control at will. If it is found that there are wires winding and knots on the door, it should be handled in time. Pay attention to whether the channel is blocked to prevent the door body from falling. In case of abnormal response, stop the motor immediately.

2、要經常性的檢查電動卷簾門上下行程的開關，對行程控制器加上潤滑油，保持正常良好的運行，另外，操作人員手動控卷簾門，檢查器運行情況，校對上下行程開關位置，使電動卷簾門開啟或關閉時處于適當位置，且檢查過程中嚴防電動卷簾門沖頂或沖底或者反轉，如若出現緊急情況應立即停止轉動，切斷電源。

2. It is necessary to regularly check the up and down travel switch of the electric rolling shutter door, add lubricating oil to the travel controller, and keep the normal and good operation. In addition, the operator manually controls the rolling shutter door, checks the operation of the device, and checks the up and down travel switch position, so that the electric rolling shutter door is in a proper position when it is opened or closed, and strictly prevents the electric rolling shutter door from rushing to the top or bottom or reversing In case of emergency, stop the rotation immediately and cut off the power supply.

3、操作員 好是經常性的要檢查好電動卷簾門的手動開關和手動升降裝飾，以防止在緊急的情況下電動卷簾門會失靈，或者造成不必要的事故。

3. The operator should check the manual switch and manual lifting decoration of the electric rolling shutter door regularly, so as to prevent the electric rolling shutter door from failure or causing unnecessary safety accidents in case of emergency.

4、要保持軌道運行暢通，及時清理電動卷簾門的軌道，保持內部清潔，卷簾門電機和傳動鏈條要經常加注潤滑劑，檢查控制箱內器件和開關控制盒，緊固接線端口，緊固螺絲等，清潔控制箱內、表面和按鈕上的灰塵污物，防止按鈕卡住而不能反彈。

4. It is necessary to keep the track running smoothly, clean the track of the electric rolling shutter door in time and keep the inside clean. The motor and drive chain of the rolling shutter door should be filled with lubricant frequently. Check the devices and switch control box in the control box, fasten the wiring port, fasten the screw, etc., and clean the dust and dirt in the control box, on the surface and on the button, so as to prevent the button from sticking and not rebounding.

在卷簾門電機端，上下有兩個六角形的調節螺栓（六角形的內螺栓）并有上下、左右箭頭指示，這個就是限位調節器，也就是開門和關門卷軸的運轉方向。在箭頭旁邊還有+和-的標志  + 代表加大行程，- 代表縮短行程，用一個六方插入對應的孔旋轉就能解決。

At the motor end of the rolling shutter door, there are two hexagon adjusting bolts (hexagon inner bolts) at the top and bottom, and there are up and down, left and right arrow indications. This is the limit adjuster, that is, the running direction of the door opening and closing rollers. Next to the arrow, there are signs of + and - + for increasing stroke and - for shortening stroke, which can be solved by inserting a hexagon into the corresponding hole and rotating.
