This happened to me once on my first use of my 5'r. I had just put all 5 sliders in and went to retract the levelers. The sliders started creeping out every time I hit the retract button. The hydraulic pump sounded really weak at the same time. I had run the batteries way down overnight so I hooked up the generator and tried again after 30 minutes. This time the pump sounded stronger and everything worked correctly.
I don't know if this makes sense, but it worked for me so I assumed the weak batteries caused the observed issue.
