My usual walk through process...
Safety Switches: First thing's first, check if the safety interlocks are engaged. These lifts have sensors that prevent driving when the platform is raised too high. Lower the platform completely and try again.
Enable Switch: There's usually a foot switch or a hand-operated enable switch that needs to be engaged before the drive function works. Make sure you're activating this while trying to drive. Sometimes it'll move but the connection is broken so this could be an issue.
Drive/Lift Selector: Some models have a switch to select between drive and lift functions. Make sure it's set to drive.
Emergency Stop Button: Check if the E-stop button is fully released on both the platform and ground controls.
Battery Charge: Even though it powers up, the batteries might not have enough juice for the drive motors. Try charging it overnight.
Brake Release: The manual brake release might be engaged. Look for a knob or lever near the drive wheels and make sure it's in the normal position.
Control Panel: That caked-on paint could be your culprit. Clean it off carefully - you might be missing a crucial switch or indicator.
Beyond that, if you're not seeing any error codes you might need to bring a tech out.
Good thing is, that's not a big unit so I imagine you've got something else capable of towing in out the corner if needed.
