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.

分别按照调整器标识指示方向，调整卷帘门的调节方向，箭头指示方向就是门体的运行方向。在标识一侧有正和负的符号，此两个符号代表卷帘门调节行程的大小。通过内六角扳手即可调整卷帘门位置高低。

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.

电动卷帘门的保养知识：

Maintenance knowledge of electric rolling shutter door:

1、在电动卷帘门的使用过程中，要尽量保持控制器和电压的稳定，禁止安装在非常潮湿的环境，另外不要随意打开遥控器，如若发现门体上有电线缠绕、打结等应及时处理。注意通道的是否堵塞，阻碍门体下降，如若发生异响应立即停止电机运作。

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、要经常性的检查电动卷帘门上下行程的开关，对行程控制器加上润滑油，保持正常良好的运行，另外，操作人员手动控卷帘门，检查器运行情况，校对上下行程开关位置，使电动卷帘门开启或关闭时处于适当位置，且检查过程中严防电动卷帘门冲顶或冲底或者反转，如若出现紧急情况应立即停止转动，切断电源。

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、操作员 好是经常性的要检查好电动卷帘门的手动开关和手动升降装饰，以防止在紧急的情况下电动卷帘门会失灵，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、要保持轨道运行畅通，及时清理电动卷帘门的轨道，保持内部清洁，卷帘门电机和传动链条要经常加注润滑剂，检查控制箱内器件和开关控制盒，紧固接线端口，紧固螺丝等，清洁控制箱内、表面和按钮上的灰尘污物，防止按钮卡住而不能反弹。

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.

在卷帘门电机端，上下有两个六角形的调节螺栓（六角形的内螺栓）并有上下、左右箭头指示，这个就是限位调节器，也就是开门和关门卷轴的运转方向。在箭头旁边还有+和-的标志  + 代表加大行程，- 代表缩短行程，用一个六方插入对应的孔旋转就能解决。

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.
