OK, let me repeat what Phoenix said, "Please post brand and model, so we can provide accurate advice. --Thanks!" Of the jack itself.
You should be able to get it from the manufacturer, and someone might be able to help. However, if you won't share even the most basic information, everyone is reduced to guessing.
I've found this kind of information every time so far by simply Googling the manufacturer, model number, and the term manual. For example, I have attached a pdf versions of the manual for the Barker, H&H Engineering, Super Power Jack on my 1983 Excella. It was used for many years. However, your trailer being so much newer, may have a different jack. Anyway, it will give you an idea of what is available.
