wolfe10 Report post Posted August 23, 2010 The hydraulic fluid returns to the jack reservoir when the jacks are stowed. To locate it, listen for the jack motor when extending or stowing the jacks (assuming they are hydraulic not electric). The fluid level is checked at the reservoir. Start by physically looking at the jack to make sure the piston (shiny part) is clean and not bent. Check the return springs. HWH is great about helping with troubleshooting over the phone: HWH 800 321-3494, 563 724-3396. Brett Share this post Link to post Share on other sites
