Bearings

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!

3.Loosen the hex nut shown in Figure 22.
