rayin Report post Posted October 2, 2024 (edited) On the end of each solenoid is a manual valve opening, it will either be a T-handle, hex nut, or plastic flip lever. Regardless of type, open it 4 turns or flip the handle 90° to open the valves of the 4 solenoids. The springs will retract the jacks, then close the valves to snug or flip the lever back to the original position. If you have jacks with no springs, use a pry bar to push the jacks to fully-retracted then close valves. As to service, determine your model# leveling system, then follow the troubleshooting section directions in the service manual. You'll find the service manual by googling your model# and service manual. Edited October 2, 2024 by rayin Share this post Link to post Share on other sites
