Stop lever angle
N:Engine manufacturer's normal use
S:Stop the pump.
(1)Free (at delivery)
(2)Use the hole at R = aa
(3)Rack position corresponding to bb
(4)Set the stopper bolt so that speed = cc and rack position = dd. Confirm non-injection. After setting the stopper bolt, confirm non-injection at speed = ee (rack position = ff or less).
