Test data Ex:
0000001801 CONTROL LEVER ANGLE
Control lever angle measurement
1. Measure the dimension L from the lever tip to the flange face (A).
2. Measure the lever angle from the pin hole R (plate).
(B): lever angle measuring hole
Alpha = a
beta: b

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 (J) and position it perpendicularly.
3. W-CSD lever adjustment [refer to fig 1 (O) and fig 2 (P)]
(1)After completing (2) above, remove the block gauge L2.
(2)Insert a block gauge (I) L3 determined from the graph (L-theta) in figure 3 (Q) between the idling set screw (G) and the control lever (F).
(3)Fix screw (B) so that the W-CSD lever (C)'s roller contacts the intermediate lever (D). Fix using the nut.
Note:
The temperature of the wax at adjustment must not exceed a.

0000002101 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
At pump speed N = N1 r/min and with the control lever angle at a from the idle position (corresponding to a shim thickness of L mm), convert the injection quantity obtained to a voltage value using the graph and adjust the potentiometer.
Vi:Applied voltage
E = conversion expression
Vo = output voltage
