Grizzly G0507, G0506, G0511 instruction manual Blade Tracking Gullet Line, To adjust blade tracking

Always adjust the blade guides away from the blade before making blade tracking adjustments.

The wheels on the Model G0506/G0507/G0511 Super Heavy-Duty Bandsaws are crowned and have rubber tires. This style requires center blade tracking for proper operation.

To adjust blade tracking:

1.Open the upper wheel cover door. Slowly rotate the upper wheel and watch where the blade rides on the wheel. If the blade stays centered on the crown of the wheel, then it is properly tracked.

2.If the blade does not ride centered on the crown of the wheel, then spin the upper wheel by hand and adjust the tracking hand- knob shown in Figure 12, until the blade is positioned correctly.

3.Spin the wheel approximately three more times to ensure that the blade stays cen- tered. Adjust and check if necessary.

4.Close the upper wheel cover door.

handwheel clockwise will move the blade further

into the saw body.

Before further adjustments can be made to the guide assembly, the guide bearings must be set even with the “gullet line.” This is the inside edge of the gullets for the bandsaw teeth.

To adjust blade guides to the gullet line:

Figure 13 shows the edge of the guide bearings set even with the gullet line. A white line (A) has been superimposed to the photo and the blade guard has been moved for clarity.

1.Loosen the hex bolt on the right side of the guide assembly (B).

2.Move the assembly in or out until the edge of the guide roller is even with the gullet. If the back bearing interferes with this, loosen the lock bolt (C) and slide it back.

3.Tighten the bolt for the guide assembly.
