0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD
Adjustment of the timer advance angle
1. Determine the timer advance angle using the graph.
2. Adjust with the screw so that the timer advance angle determined in item 1 is obtained.
X = temperature t (deg C)
Y = timer stroke TA (mm)
(A) = timer stroke
