BLADE TENSION

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.
Blade tension was set at the factory. When adjustment
is needed please follow the procedure below.
The gauge (1) on the bracket (2) at the rear of the upper
wheel indicates the proper tension for the various blade
widths.

the blade width, as shown.
2. Turn the blade tension knob (3) clockwise to tighten
the blade, counterclockwise to loosen.
3. As you become familiar with the saw, you may try 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.

BLADE TRACKING (FIG. M)
WARNING
!
To avoid injury, turn the switch OFF and disconnect the
saw from the power source before making any
adjustments. NEVER make tracking adjustments with
the machine running.
Blade tracking was set at the factory. When adjustment
is needed please follow the procedure below.
1. The blade (1) must be tensioned properly before
adjusting the tracking. (See BLADE TENSION).
2. Open the upper cover.
3. Move the blade guides (2) and support bearings (3)
away from the blade, if necessary.
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
turns.
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.

tracking knob counterclockwise, moving the blade
toward the center.
NOTE: Turn the tracking knob SLIGHTLY to make blade
tracking adjustments.
