Test data Ex:
0000001801 V-FICD ADJUSTMENT
Adjustment of the V-FICD
1. Install the V-FICD and adjust using screw A so that the clearance between the intermediate link and the actuator is S1.
2. Apply negative pressure P1 to the actuator and confirm the full stroke.
----------
S1=1+1mm P1=-53.3kPa(-400mmHg)

S1=1+1mm
0000001901 A/T PLATE ADJUSTMENT
A/T plate adjustment
Rotate the control lever from the idle position (B) to the full-speed position (C).
Adjust the A/T plate (A) so that (A) (C) - (A) (B) = L1, and fix.
When fixing, fix the A/T plate within the range L3 from the center of the control lever's wire hole (hole L2).
(B) Idle position
(C) Full position

0000002101 W-CSD ADJUSTMENT
Adjustment of the W-CSD
Adjustment of the timer advance angle
1. Determine the timer advance angle using the graph (graph TA).
2. Adjust with the screw (A) so that the timer advance angle determined in item 1 is obtained.
X:Temperature t (deg C)
