CARRIAGE BEARING TRACKING
Bearing tracking can be checked by placing a strip of white paper over the area where the bearings ride. With the drive gear disengaged (handle down), move the carriage over the strips. If the tracking is correct the bearings will leave a uniform trace on the paper. See Figure A.8. If traces are not corrrect add shims as necessary. See Figure A.9.
