blade stops fluttering, then tighten the ten-

sion one more quarter of a turn.

7. Tighten the wheel lock knob bolt loosened in

step 3.

NOTICE

All bandsaw blades will stretch. To reduce

this stretching, remove the tension from the

blade when not in use.

NOTICE

After blade tension and tracking are set cor-

rectly, properly adjust the upper and lower

support bearings and guide-block assem-

blies into position before cutting operations.

Figure 22. Upper blade guide assembly.

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.
