Current Regulator

With armature in cutout position, adjust "a" to 0.04 - 0.056" (1.02 - 1.42 mm) by bending "C".
With armature in cutin position, make sure "d" is 0.012 - 0.031" (0.31 - 0.79 mm). Check, and if necessary, adjust gap "b" to 0.012" (0.31 mm) minimum by bending "B" (stationary contact).
To make the electrical adjustment, bend stop "C" to achieve correct cutin values (see specifications).
