Blade Tracking
Your band saw is equipped with an adjustable blade tracking
mechanism which assures proper blade tracking at all times. The
back edge of a properly aligned blade will run lightly against one or
both of the back up rollers in the blade guides. (The pressure
between the edge of the blade and the roller will be very slight and
FIG. 4
will not damage either the blade or the roller.)
To adjust the blade tracking follow the steps listed below.

c. Holding the blade in the guides, place it around both pulleys
and through the guard, as shown in Figure 7.
d. Make sure that the blade is fully inserted into the blade guides
(against the back edge support rollers shown in Figure 8), and
positioned squarely against the rubber tires.
e. Gently turn the saw over so that the pulleys rest on your
work bench or table and rotate the blade tensioning lever
counterclockwise until it stops, as shown in Figure 9. Make
sure the teeth on the left side of machine point to the rear
(motor end) of the bandsaw.
f. Turn the saw ON and OFF a few times to ensure that the
blade is seated properly.
TURN OFF AND UNPLUG THE BAND SAW!
Use a 9/16" (20mm) wrench to loosen the adjustment locking
nut, shown in Figure 9 by turning it one or two turns
counterclockwise.
Use a screwdriver to turn the tracking screw 1/4 turn. Turning
the screw clockwise will move the blade up toward the blade
guide rollers. Turning the screw counterclockwise will move the
blade down away from the rollers.
Adjust so that the back edge of the blade lightly touches the
rollers and securely tighten the locking nut. (It will be necessary
to plug the saw in and run it to observe the tracking.)
