Test data Ex:

0000001801 MICROSWITCH ADJUSTMENT

Microswitch adjustment 1.Fix the control lever so that the distance between the control lever and the idling stopper bolt is L (control lever position: a). 2. In the above condition, adjust the installation position of the microswitch so that so that it turns OFF. Must change from ON to OFF at L1. [Lever angle b (from idle).] (A): microswitch fixing bolt
----------
L=6.0mm L1=5.6~6.4mm a=14deg b=13~15deg
----------
T=2~3N-m(0.2~0.3kgf-m) L=6.0mm

0000001901 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the actuator rod to obtain S1. 2. Apply negative pressure P1 kPa {P2 mmHg} to the actuator and confirm that it moves through its full stroke. (A) Control lever (Idling position)
----------
S1=1+1mm P1=-53.3kPa P2=-400mmHg
----------
S1=1+1mm
