0000001801 M-CSD ADJUSTMENT

M-CSD adjustment
1. Fixing the M-CSD
(1)At roller holder advance angle a adjust the lever shaft ball pin so that it contacts the roller holder.
(2)At this time, adjust the position of the M-CSD lever (A) using adjusting screw (C) so that the clearance between the M-CSD lever (A) and the stopper (B) becomes L1. Then fix using nut (D).
TT
2. M-FICD adjustment
(1)Move the CSD lever (A) through its full stroke.
(2)Adjust screw (E) so that the control lever (G)'s position is b (the clearance between the control lever and the idling set screw is L2). Then fix using the nut (F).

0000001901 MICROSWITCH ADJUSTMENT

Microswitch adjustment
1. Set the control lever position at a (distance from the idling setscrew is L1).
2. Adjust the lever screw so that the microswitch turns ON and fix using the nut.
Adjustment of the V-FICD
1. V-FICD installation position adjustment
(1)Maintain the control lever position b.
(2)Adjust the position of the bracket so that the clearance between the control lever's roller and the actuator's hook at initial installation is L2. Then, fix using the nut.
2. V-FICD stroke adjustment
(1)Move the actuator through its full stroke.
(2)Adjust the adjusting screw so that the control lever clearance is c (the clearance between the control lever and the idling set screw is L3), then fix using the nut.
(3)Confirm full stroke at P1 {P2}.
