Adjusting Upper Blade Guides and Blade Support Bearing

WARNING: Blade guard has been removed for pic- ture clarity. Never operate the band saw without all guards in place and in working order. Failure to comply may cause serious injury.

1. Disconnect machine from the power source.

2. Blade must already be tensioned and tracking properly.

3. Loosen thumb screws and move guide blocks as close to

the blade as possible without pinching it. The thickness of

a dollar bill on each side of blade is a good rule of thumb.

4. Tighten thumb screws.

5. Loosen thumb screw and turn knurled knob to move the

guide block bracket in or out until the front edge of the

guide blocks are just behind the “gullets” of the saw teeth.

6. Tighten thumb screw.

7. Loosen thumb screw and turn knurled knob to move

the support bearing in or out until the bearing is 1/64”

behind the blade.

8. Tighten thumb screw.

9. Blade support bearing should be adjusted so that the

back edge of the blade overlaps the front face of the

ball bearing approximately 1/8”. To change position of

the bearing, remove screw bearing, and back off

knurled knob completely to remove the bearing shaft.

Notice the bearing holder on the shaft is eccentric. Re-

install the bearing shaft, the bearing, and the screw.

Examine the overlap between the bearing face and the
