Test data Ex:

0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust to obtain S. 2. Confirm that L1 is obtained when negative pressure P1 (P2 ) is applied to the actuator. To adjust the stroke adjust the actuator's stroke adjusting screw (C). (A) Control lever (B) Lock nut (Tightening torque T) (C) Stroke adjusting screw

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) = L3, and fix. When fixing, fix the A/T plate outside the range diameter 9.2 mm from the center of the control lever's wire hole (hole dia. 8.5 mm). (B): B idle position (C): B' full
