I have a 2011 Georgetown, slideouts and jacks are all hydraulic. Does anyone know how to retract them manual if the system fails? Found info on the internet to use a drill to turn the motor on the pump, but how do you activate the solenoids to retract each item?

I was told not to use them to lift the wheels off the ground to level the unit because the seal will go faster on the cylinders need to use boards to get the unit close to level. (2011 374ts Georgetown) Is this true?
