Fill the water and charge it up. If the battery doesn't come back, make a battery cable to hook up to another machine (of the same voltage) and see if it works with a battery you know that is good.
It's an electrical forklift. Generally the problem is in the electricity.
Forklift was for over the year not used. The battery is dry.
Probably it doesn't lift or move correctly....what I've heard.
I've never seen it works.
I have no clue what that is. What sort of issue are you having? If it's electrical, most old trucks use pretty generic stuff. Such as a resistor panel or a GE SCR control board (C185, M210, EV1, etc). We might be able to help you with your specific issue.
