If it was necessary to rotate the control handle
clockwise to obtain continuity, turn the eccentric
adjustment to move the pin down (or toward the
pump). If a counterclockwise rotation of the
handle was necessary to obtain continuity,
rotate the eccentric to move the pin up (or away
from the pump). Only a small amount of
adjustment in either direction is needed to
center the pin in the internal mechanism cam
Turn the eccentric a maximum of 14 of a turn
