warning upun removal of the shipping aids ,please make sure

Warning upon removal of the shipping aids,
please make sure that the drawers are latched。
If more than one drawer is open at the same time,
the unit may become,unstable and tip forward。
我也发现个错误upun,没这个词,应该是upon,
关于运输设备的拆除警告：
请保证所有抽屉都处于锁闭状态。
如果有两个及以上的抽屉同时打开时,
此设备将重心不稳而前倾。
