Changes in blade width and the type of material
being cut will have an effect on blade tension.
Keep in mind that too little or too much blade
tension can cause blade breakage and/or poor
cutting performance.
TIP: When the band saw is not being used, slightly
release the tension on the blade – this will prolong
the blade’s life. Make a note of the specific tension
setting for that particular blade, as shown on the
gauge (D, Figure 14). The tension can then be re-
set quickly when band saw operations are
resumed.
Blade Tracking
“Tracking” refers to the position of the saw blade
on the wheels while the machine is in operation.
Tracking has been factory-adjusted. However, it
should be checked occasionally, including after
every blade change.
IMPORTANT: Make tracking adjustments with
knob (F, Figure 15). DO NOT use screws (G,
Figure 15); these were used by the manufacturer
for wheel alignment and should NOT be used for
blade tracking.
To inspect and adjust tracking, proceed as follows:
1. Disconnect machine from power source.
2. The blade must be properly tensioned before
adjusting blade tracking. Make sure the blade
guides and other parts of the machine will not
interfere with the movement of the blade.
3. Open upper front door to expose the upper
wheel. Rotate the wheel clockwise by hand,
and observe the position of the blade on the
wheel. The blade should ride upon the center
of the wheel (Figure 16).
4. If the blade tends to move toward the edge of
the wheel, loosen wing nut (E, Figure 15) and
slightly rotate knob (F, Figure 15). Rotating
the knob clockwise will cause the blade to
move toward the rear edge of the wheel.
Rotating the knob counterclockwise will cause
the blade to move toward the front edge of the
wheel.
NOTE: This adjustment is sensitive; perform it
in small increments and give the blade time to
react to the changes, as you continue to rotate
the wheel.
5. When the blade is tracking properly in the
center of the wheel, re-tighten wing nut (E,
Figure 15).
6. Close upper front door.
