WARNING:
Blade guard has been removed for picture clarity.
Never operate the band saw without all guards in
place and in working order. Failure to do so could
result in possible serious personal injury.
n Unplug the saw and remove switch key.
n Blade must already be tensioned and tracking properly.
n Loosen thumb screws and move blade guides 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.
n Tighten thumb screws.
n Loosen thumb screw and turn knurled knob to move
the blade guide bracket in or out until the front edge of
the blade guides are just behind the “gullets” of the saw
teeth.
n Tighten thumb screw.
n Loosen thumb screw and turn knurled knob to move the
thrust bearing in or out until the bearing is 1/64 in. behind
the blade.
n Tighten thumb screw.
n Blade thrust bearing should be adjusted so that the
back edge of the blade overlaps the front face of the ball
bearing approximately 1/8 in. 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. Reinstall 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
in.
