1. Starting of Engine
When the control-lever of the governor is removed to the starting position
(maximum-speed-stopper) by means of the hand-lever or pedals through the link, the bosses
of the swivel-lever which move together with the control-lever, will be separated from the
guide-lever, and the governor-spring, which is connected with the tension-lever, is stretched.
This governor-spring pulls the tension-lever to the place of full-load stopper. Then the shifter
and the guide-bush act on the left side and the weak start-spring will move the floating lever
so as to transfer the control-rack of the injection pump to the starting point beyond the
position of the full-load. Thus the start of engine will be easily yielded.
