Check your resevior oil level ensure it is properly filled with Jacks up and slides in. If full check you slide valves to ensure they are open fully. If not full add oil (not sure of the type for your unit, but it should be posted near the pump) and then try........... Jacks and 1 slide on my unit are hydraullic operated and one slide electric...... Let us know what you find out....
