Thecylinder is not worn at the bottom but is round so it willguide the hone to straighten cylinder bore. As thebottom of the cylinder increases diameter, graduallyincrease strokes until hole travels full length of bore. Donot extend hone more than 3/4" (20.0 mm) to 1" (25.0mm) at either end of cylinder bore.As cutting tension decreases, stop hone and tightenadjusting knob.
