If your slides are hydraulic and the electrical system for the slides fails you can run the pump with a drill motor. Locate the pump assembly in the front compartment, on the end of the motor you will see paper seal/disc in the center, punch a hole in this, get a long screwdriver bit and place it backwards in your drill, this gives you a hex drive, place this in the end of the motor and use the drill to run the motor and pump. One direction will run your slides in, the other out. Hope this helps
