0000001801 M-CSD ADJUSTMENT
M-CSD adjustment
1. Fixing intermediate lever screw (A) [roller (E) must not contact intermediate lever (D)]
(1)Hold the control lever C in the idling position.
(2)Insert a block gauge (thickness gauge) L1 between the intermediate lever D and the intermediate lever bracket J and fix intermediate lever D.
(3)At this time, adjust screw (A) so that it is horizontal and the clearance between screw (A) and the control lever (C) is L2. Then, fix using nut (B).
2. Fixing the M-CSD stopper (I)
(1)At roller holder advance angle b, adjust the lever shaft ball pin so that it contacts the roller holder.
(2)At this time, fix the stopper I using the screw J where the distance a between the CSD lever F and the stopper is L3.
(3)Pull the CSD lever F in the direction X until it contacts the stopper I and confirm that the timer stroke is L4.
3. Screw G adjustment (without a block gauge L5 at a)
(1)Adjust the screw (G) so that the clearance between the screw (A) adjusted in 1. above and the control lever (C) is at least L6. Then, fix using the nut (H).
(2)Confirm that the control lever shim thickness L = L7.

0000001901 DASHPOT ADJUSTMENT
Adjustment of the dash pot
1. Insert a block gauge L (thickness gauge) between the idle set screw (C) and the control lever (D).
2. In the above condition, adjust the dashpot adjusting screw (A) so that it contacts the pushrod, and then fix it using the locknut (B).
Note:
(1)The adjusting screw and pushrod contact faces must be smooth.
(2)Confirm that the control lever returns to the idling position.
