ACS adjustment
Full load injection quantity at high altitudes and ACS adjusting method
1. Full load injection quantity adjustment
(1)Remove the ACS cover and remove the bellows and adjusting shim.
(2)Perform all adjustments as per the adjustment standard except for ACS adjustment.
2. ACS adjustment
(1)Assemble the ACS cover, bellows and adjusting shim.
(2)At pump speed N1, adjust using a shim to obtain the decrease for the altitude shown in the table.
X1 = atmospheric pressure
X2 = altitude
Y = decrease quantity
(A) = adjustment value

0000001801 STARTING I/Q ADJUSTMENT
Starting injection quantity adjustment
Adjust adjusting bolt so that the starting injection quantity is within the standard.
Fix using nut.
(A): Lock nut.
(B): Stopping lever

0000001901 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
At pump speed N = N1 and with the control lever angle at a from the idle position (corresponding to a shim thickness of L), convert the injection quantity obtained to a voltage value using the graph and adjust the potentiometer.
Caution: Confirm that the voltage increases when the control lever is turned to the full speed side.

0000002001 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Timer advance adjustment (refer to Fig 1 [O], 3 [Q]).
(1)Determine the timer advance angle from the graph in Fig. 3 (Q).
(2)(1) Adjust with the screw (A) so that the timer advance angle determined in the item (1) is obtained.
2. Setting the intermediate lever position (refer to fig 1 and fig 2)
(1)Insert a block gauge L1 between the idling set screw (G) and the control lever (F).
(2)Align the intermediate lever (D) with the aligning line and position it perpendicularly. Adjust the screw (E) so that it contacts the control lever (F), then turn the screw 0.5 ~ 1 turns counterclockwise and fix.
[At this time, tilt the intermediate lever clockwise b from a perpendicular position to obtain L3 shown in Figure 1 (O).]
3. W-CSD lever adjustment [refer to fig 1 (O) and fig 2 (P)]
(1)Insert a block gauge L2 determined from the graph (L-t) in figure 3 (Q) between the idling set screw (G) and the control lever (F).
(2)Fix screw (B) so that the W-CSD lever (C)'s roller contacts the intermediate lever (D).
Adjust the screw (B) until the screw (F) contacts the control lever (G). Then fix locknut (A).
Note:
Apply red paint after adjustment.
When inserting the block gauge, separate lever (C) and (D) using screw (B) to prevent excessive force on the lever.
