One point: from the use of the situation.

电动伸缩门因为是由遥控器所控制操作的，所以，有效的保持电器控制以及电压的稳定性是非常关键的。在使用电动伸缩门的时候，最好不要私自的打开其遥控器，也要随时避免电器被潮湿侵害，甚至摔坏的可能性。

In the use of the electric expansion door, it is better not to open its remote control, also at any time to avoid the possibility of electrical damage, or even broken.

第二点：从清洁保养来看。

The second point: from the clean maintenance.

电动伸缩门为了运行的顺畅，轨道的清洁就变得必不可少了，不过，不能为了保持轨道的畅通，而添加一些油，因为这样会加重轨道的负担。

In order to run smoothly, the cleaning of the track becomes necessary. However, no oil can be added to keep the track open, which will aggravate the burden of the track.

电动伸缩门的控制箱也是很重要的一部分，需要随时清洁其内部，表面以及按钮上面的一些灰尘，并且随时的关注和检查控制箱内的重要器件以及开关控制盒，而电动伸缩门的电机和传动链条的表面需要注意添加一些润滑油，使得其运行顺利。

第三点：从操作开关来看。

The third point: from the operation switch.

电动伸缩门的操作开关需要时常检查，听其位置是否正确，开关和闭合是否在适当的位置。

The operation switch of the electrotelescopic door needs to be checked regularly to see if its position is correct, and whether the switch and closure are in the proper position.

电动伸缩门的电动刹车，手动开关以及手动起闸装置等，也需要经常检查，避免遇到紧急情况，电动伸缩门无法正常的操作，而发生意外。

Electric brake, manual switch and manual brake device of electric telescopic door also need regular inspection to avoid emergency, electric telescopic door can not operate normally, and accidents happen.

第四点：从消防安全来看。

Fourth: from the fire safety point of view.

电动伸缩门可以利用温感检查其功能。

The electric telescopic door can use the temperature sense to check its function.

所以，我们可以看到，电动伸缩门虽然在使用上面比其他的门简单快捷很多，但是如果平时不注意维护的话，也是很容易发生安全事故的，因为它是电动操作的。因此，不管是不是电动伸缩门十大品牌的产品，都是需要我们及时的检查和保养的，安全才是最重要的。

So we can see that although the electric telescopic door is much simpler and faster than using other doors, but if we don't pay much attention to maintenance at the time, it is also easy to happen safety accidents, because it is electric operated. Therefore, whether or not the ten major brands of electric expansion door products, it is necessary for us to check and maintain in time, safety is the most important.
