between the top surfacre of throat plate and tongue stopper
7 is 14 ± 0.5 mm with the tongue section raised.
Insert the gauge between the throat plate and tongue stopper
7, and perform adjustment as shown in the figure since
dimension A of the gauge supplied as accessories is 14 mm.
3. Loosen sensor setscrew located on the side of cylinder, adjust
