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
blade. Change the position of the bearing shaft until
the overlap is approximately 1/8".
