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.
