NOTICE

Whenever changing a blade or adjusting tension and tracking, the upper and lower blade support bearings and blade guide bearings must be properly adjusted before cutting operations.

The support bearings are positioned behind the blade for support during cutting operations, because the blade is typically pushed back with the pressure from the advanc- ing workpiece. Proper adjustment of the support bearings is an important part of making accurate cuts and also keeps the blade teeth from coming in contact with the guide bearings while cutting.

To adjust the upper support bearing, do these steps:

1.Make sure the blade is tracking properly and that it is correctly tensioned.
