首先要找到r连接车库门的中央滑轨，上面有个L型的曲臂连接车库门和opener的链条／皮带。

First, find the central sliding rail of the R connecting the garage door, with a L type curved arm connecting the garage door and the chain / belt of the opener.

 

 

曲臂一端有根绳子吊在那里。拉住这个绳子往下一拽，滑动的trolley就脱离链条了。这个时候你就可以手动开关车库门了。

There is a rope hanging from one end of the arm. Pull the rope down and pull the trolley out of the chain. You can switch the garage door manually at this time.

 

 

车库门脱离了opener，就不能通过opener的力量锁住门了，所以这时候，要锁住门就需要用到门侧面的门闩了。门闩一般长这样

The garage door is out of opener and can't lock the door through the power of opener, so at this time, the door latch is needed to lock the door. The latch is usually long.

 

 

推进门侧轨道上相应的洞里，就把门锁好了。要开的时候再拔出来。

Push door track corresponding hole, you have locked the door. Pull it out when you want to open it.

 

 

等来电了，需要把opener重新连到车库门上，方法也很简单，把绳子上端的活动部件拉到水平就行了，按墙上的车库门开关，当链条上的相应部件走到正确的位置就自动把车库门接上了。

After calling, it is necessary to reconnect opener to the garage door. The method is also very simple. Pull the moving part of the upper part of the rope to the horizontal level, press the garage door switch on the wall, and when the corresponding parts on the chain reach the correct location, the garage door is automatically connected.
