You must use a 5/32 mil Allen key and turn the solenoid which controls the fluid movement.The Allen key inserts on the end of the solenoid.Turn it in the opposite direction which is open, disconnect the power plug on the end of the solenoid,then using drill - wind your slide in.Then turn it back to the closed position.
Your kitchen and living room slide are most likely on the same solenoid.
Your legs have a separate solenoid,only open 1 solenoid at a time.
IF you do NOT open the solenoid .....then using the drill is a waste of time because the fluid cannot flow back to the tank.
