Test data Ex:

0000001801 A/T PLATE ADJUSTMENT

Adjustment of the V-FICD 1. At idle lever position L1, adjust to obtain S. (Apply negative pressure P1 {P2}). 2. Confirm that L in the figure changes to L2 when negative pressure P3 {P4} is applied to the actuator. To adjust the stroke adjust the actuator's stroke adjusting screw (C) (Tightening torque T). (A) Control lever (B): lock nut (C): stroke adjusting screw (D): Actuator (E): actuator shaft
