STEP 12:
Adjust the rollers if the ROLLER CARRIAGE (Q) rolls up and down the tube with difficulty, or if it seems to sloppy.
Unscrew the cable end from the roller carriage housing.
Remove the SCREWS (Y) that hold the two PLASTIC COVERS (Z) together.
There are two ROLLER ADJUSTMENT SCREWS (AA), each with a spring, on the back side of the roller carriage housing. The roller drag can be increased/decreased by adjusting these screws.
