0000001801 W-CSD ADJUSTMENT

Adjustment of the W-CSD 1. Adjustment of the timer stroke Adjust using screw (A) so that the timer stroke is the value determined using the graph (W). [(K), (M)] 2. Adjustment of the position of the intermediate lever. With a shim L5 inserted between the control lever (I) and the FICD set screw (E), insert a shim (L3) between (I) and the idle screw (G). Align the intermediate lever (F) with the aligning mark (J) and then fix the intermediate lever adjusting screw (E) so that (E) contacts the shim between (E) and (I). [(U), (V)] 3. Adjustment of the FICD Insert the shim (L4) between the control lever (I) and the idle set screw (G). Use adjusting screw (B) to fix the CSD lever (C) in the position where it operates the intermediate lever (F) via the rod (D). [(U), (V)] However, set with a shim L5 inserted. [(U), (V), (W)] (O) Timer stroke adjustment (mm) (P): lever angle (deg) (Q): lever angle (deg) The (Q) indicates the clearance between the control lever and the idle set screw.
