下面就是在日常的使用中我们需要了解一些基本的保养

Next, we need to know some basic maintenance in daily use.

1、使用方法正确

1. The use of the method is correct

在使用中，动作要尽可能的轻开轻关，不要用力过大过猛;电动伸缩门的开启时，发现有阻碍，应先排除故障。内开内倾窗、折叠电动伸缩门等高档电动伸缩门要严格按说明操作。

In use, action should be as light as possible and not overexert. When electric telescopic door is opened, obstacles must be found. In the open window, introverted folding electric telescopic door and other high-grade electric retractable door should be in strict accordance with the instructions.

2、经常清洗

2. Regular cleaning

经常清洗，保持表面的清洁，在擦洗时尽量选择软质的纱布或棉丝等，以免划坏电动伸缩门的表面。在有污渍和脏物时，可用清水、酒精或中性洗涤剂、进行清洗

Always clean, keep the surface clean, and try to choose soft gauze or cotton yarn when scrubbing, so as to avoid scratching the surface of the electric telescopic door. When it has stains and dirt, it can be cleaned with clear water, alcohol or neutral detergent.

3、防腐蚀

3, anticorrosion

尽量避免酸性、碱性化学物品接触铝合金电动伸缩门表面。

Try to avoid contact with acidic and alkaline chemicals on the surface of aluminum alloy electric telescopic door.

4、五金件保养

4, hardware maintenance

经常检查电动伸缩门的各类五金配件，如发现有损坏现象时及时进行修理或更换，五金件用久了，可涂少许的火蜡油或者滴些机油，减少摩擦力，保持电动伸缩门的开启关闭轻松灵活。电动伸缩门的密封毛条和玻璃胶条是密封保温的关键两个部件，如有老化松脱的情况，应该及时更换。

Often check all kinds of hardware and accessories of the electric expansion door. If the damage is found, it can be repaired or replaced in time. The hardware is used for a long time. It can be coated with a little fire wax oil or some oil, so as to reduce the friction and keep the opening and closing of the electric expansion door easy and flexible. The seal and sliver and the rubber strip of the electric expansion door are the two key parts of the sealing and thermal insulation. If there is aging loose condition, they should be replaced in time.
