Test data Ex:

0000001801 MICROSWITCH ADJUSTMENT

Microswitch adjustment With the control lever a from the idle position (idle stopper lever clearance L1) and the microswitch ON, gradually move the microswitch and fix it in the position where the microswitch goes OFF. (From the idle position the microswitch is on at a.)
----------
a=26+-1deg L1=8.5+-0.2mm
----------

0000001901 FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust so that the distance between the control lever and the FICD shaft is S. 2. Apply negative pressure P to the actuator and confirm the full stroke.
----------
S=1+1mm P=-53.3kPa(-400mmHg)
