Blade Tracking

Personal injury or death can occur if the machine starts while your hand is touching the bandsaw wheel during tracking adjustments. Disconnect power from the bandsaw before performing blade tracking adjustments.

The blade tracking is primarily affected by the tilt of the upper wheel, also known as "Center Tracking"; and the alignment of both wheels, also known as "Coplanar Tracking." (For Coplanar Tracking, see the Wheel Alignment instructions on Page 51.)

The wheels on this bandsaw were aligned at the factory, so Center Tracking is the only adjust- ment that needs to be performed when the saw is new.

To center track the blade:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the upper and lower blade guides are adjusted away from the blade.

3.Engage the quick tension lever and turn the blade tension handwheel until the tension scale (Figure 16) reads between 4 and 6.

4.Spin the upper wheel by hand at least three times and watch how the blade rides on the crown of the wheel. Refer to Figure 17 for an illustration of this concept.

—If the blade rides in the center of the upper wheel and is centered on the peak of the wheel crown, then the bandsaw is already tracked properly and no further adjustments are needed at this time.

—If the blade does not ride in the center of the upper wheel and is not centered on the peak of the wheel crown, then continue with the following steps.

The cast iron spokes may have sharp edges and the blade teeth may extend beyond the edge of the wheel, creating a laceration hazard. Be careful when turning the wheels by hand.
