The battery is fully charged, and the level on the gauge shows full.
The brake fluid reservoir is half full with the cap off. This thing has me scratching my head.

well with that display it should show you the error code in such a way -02, if that is the code it is saying the forward directional switch is closed on initial startup.

But if this truck uses the monotrol pedal it defaults to forward drive anyway so that may be normal. If it has a hand selector for the directional control then it may be in a selected direction or the switch may be stuck or have a faulty switch.

As for the 'water drop' as you put it that is a drop within a circle with brackets around the circle? This is brake fluid, indicating the brake fluid is low, if the fluid is not low then the float inside the reservoir may be stuck or faulty.

since it drives but the lift does not work what is the charge level of the battery? generally the battery symbol on the dash would illuminate if the battery is low which would place the unit in battery cut out mode but if it is not lit that may not be the case but i would check the battery anyway if the level shows towards the low end of the gauge.

Hello, this is my first time dealing with this type of lift, so i don't even know where to begin. there is an error code 2 on the display. also the wrench light and water drop are illuminated. The lift does not have any documentation or user manual, as it was a donation for a 501c3 company

Hello, are there currently any fault codes on the display? Example 42, 43,..
You can also look at the contactors in the counterweight to make sure they all have a good connection or aren't worn.. sometimes you can get lucky and it's just a fuse for the hydraulic pump.. please update when you can, thank you
