BLADE TENSION(FIG. L)
WARNING
To avoid injury, turn the switch OFF and disconnect the
saw from the power source before making any
adjustments.
NEVER make tension adjustments with the machine
running.
The gauge (1) on the bracket (2) 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 (3) clockwise, raising the
upper wheel to tighten the blade. Turn the knob
counterclockwise to lower the upper wheel, loosening
the blade.
3.
As you become familiar with the saw, you may want
to change the tension settings.
NOTE: Changes in blade width and 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, relax the blade tension.

WARNING
To avoid injury, turn the switch OFF and disconnect the

adjustments.
NEVER make tension adjustments with the machine
running.

The blade (1) must be tensioned properly before
adjusting the tracking.
2.
Open blade (1) the upper cover.
3.
Move the blade guides (2) and support bearings (3)
away from the blade, if necessary. See page 15 for
bearing and guide adjustment.
4.
Rotate the wheel (4) slowly forward by hand, and
check the position of the blade on the wheel. The
blade should remain centered on the wheel as it turn.
5.
If the blade moves toward the front of the wheel, turn
the tracking knob (5) on the rear of the band saw
clockwise. This tilts the top of the wheel and moves
the blade toward the center.

If the blade moves toward the back edge, turn the
tracking knob counterclockwise, moving the blade
toward the center.
NOTE: Turn the tracking knob SLIGHTLY to make
