Test data Ex:

0000001801 MICROSWITCH ADJUSTMENT

Microswitch adjustment 1. Insert a shim L mm (control lever position: a) between the control lever and the idling stopper bolt. 2. Move the microswitch in the direction of the arrow so that it turns ON. 3. Move the microswitch again in the direction of the arrow and tighten the microswitch fixing bolt where 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 to the actuator and confirm the full stroke. (A) Control lever (Idling position)
----------
S1=1+1mm P1=-53.3kPa(-400mmHg)
