Try
Pressing the release bar down. While holding it down, try turning the tension bar counter clockwise to drop the wringer into position. After it drops in, then turn the tension lever clockwise to put maximum tension to wring the clothes out. When finished, press the release bar to release maximum tension. At that point, if your not going to use for awhile, you can press the release bar, and while
(while being the operative word here) holding down, turn the the tension lever clockwise, and lift up about two inches, let the tension lever go back on its own, and set down. When you do this it should hold the rollers about a inch apart. This avoids flat spots on the rollers while not in use.
There is a manual somewhere here in the forum with pics if you need it. Just let us know.
