Chapter 3 Service Adjustments
To adjust the horizontal size coils (see Figure

2.Hide Blue. View Red and Green.
3.If Red is outside of Green on both sides, or inside of Green on both sides, use a Delrin .100 hex alignment tool to adjust the Red horizontal size coil to correct the error. If Red is outside of Green on one side and inside of Green on the other side, this is most likely caused by Red not being centered correctly and can be corrected with the centering adjustment (User’s Guide, Section 5.5.11).
If the Red horizontal size coil does not completely eliminate the size error between Red and Green, balance the error on both sides to allow for easier convergence.
4.Repeat Steps 2 and 3 above for Blue while hiding Red.
5.Recheck all Geometry and Convergence settings and readjust wherever necessary.
6.Replace the electronic module and rear cover.
