Why is my lift beeping and not driving or raising properly?

[Elizabeth Williams]

My lift beeps and won't drive unless it is raised. Now it only raises sometimes and drops back down by itself. What could be causing this problem?

Sounds like a safety interlock or sensor issue, try check the hydraulic fluid, limit switches, and tilt/level sensor first, if it’s dropping on its own, I wouldn’t keep running it until it’s checked.
