The gauge on the bracket at the rear of the upper
wheel housing indicates the proper tension for the various
blade widths.
1. Set the blade tension gauge to correspond with the
width of the blade in use.
2. Turn the blade tension knob clockwise, raising the
upper wheel to tighten the blade. Turn the knob count-
er-clockwise to lower the upper wheel, loosening the
blade.
Note: Changes in blade width and the type of material
being cut will have an effect on the blade tension. Too
much or too little tension could break the blade. When
the band saw is not in use, loosen the tension on the
blade, to prolong blade life.
Before making blade tension adjustments, make sure that the switch is in the “OFF” position and that the power
cord is unplugged.
BLADE TENSION ADJUSTMENTS
BLADE TRACKING ADJUSTMENTS
Note: The blade must be tensioned properly before
adjusting the tracking.
1. Open the upper wheel cover door and move the
blade guides and support bearings away from
the blade, if necessary. See page 12-13 for bearing
and guide adjustment.
2. Rotate the wheel slowly forward by hand, and check
the position of the blade on the wheel. The blade
should remain centered on the wheel
as it turns.
A) If the blade moves toward the front of the wheel, turn
the tracking knob
on the back of the band saw
clockwise. This tilts the top of the wheel to the back and
moves the blade toward the center.
B) If the blade moves toward the back edge, turn the
tracking knob
counter- clockwise, moving the blade
toward the center.
Note: Turn the tracking knob in 1/2 turn increments,
re-check and adjust again as needed.
