The support bearings are positioned behind the
blade. They support the back of the blade during
cutting operations. Proper adjustment of the sup-
port bearings ensures accurate cuts by eliminat-
ing front-to-back blade flex. There is a support
bearing both above and below the table.
To adjust the support bearings:
1. Make sure the blade is tracking properly and
that it is correctly tensioned.
2. Disconnect the machine from the power
source!
