" x 10" Metal-Cutting Bandsaw
Blade Tracking
The blade tracking has been properly set at
the factory. The tracking will rarely need to be
adjusted if the bandsaw is used properly.
To adjust the blade tracking on the bandsaw:
1. UNPLUG THE BANDSAW!
2. Position the bandsaw in the vertical position
and close the feed rate ON/OFF valve.
3. Open the wheel access cover.
4. Loosen, but do not remove the lower cap
screw in the blade wheel tilting mechanism
(Figure 41).

5. Relax the blade tension.
6. Adjust the tracking set screw with a 4mm hex
wrench as shown in Figure 41, then tighten
the cap screw loosened in Step 4.
—Tightening the set screw will move the
blade closer to the shoulder of the wheel.
—Loosening the set screw will move the
blade away from the shoulder.
7. Tension the blade.
8. Put the gearbox in neutral by moving the
gear change lever between two of the speed
positions and spin the wheel by hand.
—If the blade tracks along the shoulder of
the wheel (without rubbing), the blade is
tracking properly and this adjustment is
completed.
—If the blade drifts away from the shoulder
of the wheel or hits the shoulder, repeat
Steps 4-7.
9. Replace the blade guard and wheel access
cover.
7. Tighten the tension knob as tight as necessary
so the blade will not slip on the wheels on
start up.
8. Put the gearbox in neutral by moving the gear
change lever between two of the speed posi-
tions.
9. Spin the wheel by hand until the blade
resumes the previous tracking.
10 Put the gearbox back in gear.
—If the tracking needs to be adjusted, refer
to the Tracking procedure in the next sec-
tion.
—If the tracking is fine, proceed to Blade
Tension on Page 31.
