-16- 18" & 20" Super Heavy-Duty Bandsaws
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.
Figure 12. Loosen the jam nut. Turning this
handwheel clockwise will move the blade further
into the saw body.
Gullet Line
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.
Figure 13. Adjust the guide assembly so the
guide bearings are even with the “gullet line.”
