There are 2 versions of the lever system
1. 4 levers 1 for each jack
2. Joystick 1 long center pole for all 4 jacks and 2 small poles for retract. I will assume you have this Joystick
The 2 small poles with the round black balls are the retract levers. The forward is for the front jacks and the rear is for the rear jacks
You push the front forward all the way and the rear backward all the way. this allows the center pole to extend the jacks. pushing the long pole forward will engage the 2 front jacks and they drop down vertical FIRST and then extend to level. Pushing the center pole to the rear drops the rear jacks down vertical then extends to raise the RV. To retract the jacks you push the rear pole forward and the front pole rearward. Doug
