Adjustment procedure of the vertical lines (1) Center, (2) Right, and then (3) Left line. Accurately match the vertical center lines (red/blue) with the green line using the centering magnets (item 2.7). The adjustment VRs shown in items 5, 6, 7, 10 and 11 (RU76, RUAG, RU73, RUA3, RUJ3, RUK2, RULI, RULS, RUJ7 and RUKG) as well as RH-Center (RUQ7), BH-Center (RUP8), should have been set to their mechanical centers previously. Including centering magnets, adjust repeatedly as required.
