How to add water to a rough terrain forklift?

1. Use a tool to open the cover above the battery of the rough terrain forklift; when prying the cover open, be careful not to damage it. 2. Open the rubber cover of the rough terrain forklift to expose the vent hole, through which the inside of the battery can be seen. Then open the battery's exhaust valve seat, and the valve seat can be unscrewed directly without opening the rubber exhaust valve. 3. Check whether there is a dry area inside the small hole and check the water level. The battery plates are wrapped in white fiberglass. Then use a dropper to draw distilled water and pour it into the battery through the vent hole. 4. It is recommended to use double distilled water (twice-distilled water), and do not use tools containing metal as water supply tools. The metal needle of the syringe should be removed and replaced with a plastic tube before use.
