Realizing this being an older resurrected thread, I'll direct my new found experience towards Rick. I also recently purchased a Condor SS and fill by AV G6 pump. The first complete fill of 3000 took a couple hours, spaced out that way to allow the pump to cool. I'm gonna be 65 in a few months, overall good health, some arthritic joints and living with both shoulders having years old scarred over rotator cuff tears. My afflictions do not stop me from doing most things,,,, just have to "think" about it sometimes. So I do 25 to 30 strokes, take a few minutes break and repeat. I've found that by positioning the pump handle under my rib cage with my hands being the padding and doing deep knee bends seems to work best for me,, fortunately my knees are still good.
