THE MANUAL FOR THE 2000-33 IS THE WORST I HAVE EVER SEEN. THE DRAWINGS MAKE NO SENSE WHATSOEVER. I HAVE STUDIED THE DRAWINGS AND THEY ARE SO LOUSY I CANNOT FIGURE HOW TO EVEN INSTALL THE NEEDLE AND IN WHAT DIRECTION-WHY CAN'T THEY PROVIDE SOME PHOTOS OR EXPLAIN IN PLAIN ENGLISH WHAT NEEDS TO BE DONE. A THREE YEAR OLD COULD PROVIDE BETTER DRAWINGS THAN THEIR SO CALLED INSTRUCTION MANUAL --WHAT A JOKE!
