Zusammenfassung:	An adjustment device for adjusting a lever arm (16) located inside a machine frame wherein the lever arm is pivotally mounted to the frame (22) at a first location and is spring (28) biased against a stop at a second location of the frame. The device comprises a resilient sleeve (18) having a shank portion adapted to extend through an aperture (20) in the frame to act as the stop, and a head portion of larger diameter than the diameter of the aperture in the frame. The shank portion has a threaded section and a non-threaded section, the non-threaded section having a length greater than the frame thickness at the aperture, wherein the lever arm pivots as a screw (26) extending axially through the sleeve is turned in the threaded section.
