1、使用大棚保温被卷帘机的时候，严禁将倒顺开关绑在伸缩臂杆上进行操作。
1. It is strictly forbidden to tie the reverse switch to the telescopic boom when using the curtain rolling machine to keep warm in the greenhouse.
2、操作倒顺开关要在温室山墙一侧，观察正反转，边观察边放保温被，严禁在棚前操作，以防卷帘机失控造成人员伤亡事故。
2. Operating the reversing switch should observe the positive and negative side of the greenhouse wall, put the heat preservation quilt while observing, and strictly prohibit the operation in front of the greenhouse, in order to prevent casualties caused by the out-of-control curtain rolling machine.
3、保温被（帘）在卷放前，应先降压——将保温被（帘）上的物品移开。尤其雨雪后，应将积雪清扫干净，若雨雪后湿透过重，将使卷帘机超负荷工作，容易造成卷帘机损坏。
3. Pressure should be lowered before the heat preservation quilt (curtain) is rolled up. The items on the heat preservation quilt (curtain) should be removed. Especially after rain and snow, the snow should be cleaned up. If the wet penetration is heavy after rain and snow, the curtain rolling machine will be overloaded and easy to cause damage to the curtain rolling machine.
4、保温被（帘）上卷到离棚顶30厘米时，及时关闭倒顺开关，切忌在卷的过程中人离开，防止卷帘机和保温被（帘）从棚顶滚落到后方，造成毁坏，带来损失。
4. When the heat preservation quilt (curtain) is rolled up to 30 centimeters from the roof, turn off the reversing switch in time, and avoid leaving during the roll-up process, so as to prevent the curtain rolling machine and heat preservation quilt (curtain) from falling from the roof to the rear, causing damage and causing losses.
5、因卷不直或走偏，使卷帘机负荷过大，易造成主机损坏。
5. Because the winding is not straight or deviated, the load of the curtain rolling machine is too heavy and the main engine is easy to be damaged.
6、卷放过程中要随时监控卷帘机的运行情况，若有异常声音或现象要及时关闭倒顺开关，停机检查并排除，防止机器带故障工作。
6. In the process of rolling and playback, we should monitor the operation of the shutter at any time. If there are abnormal sounds or phenomena, we should turn off the reverse switch in time, check and eliminate the shutdown, so as to prevent the machine from working with faults.
