2. Turn the upper wheel by hand a few times and
notice if the blade remains in the center of the tire
on the top wheel.
If the blade moves away from the center of the
tire while you are turning it, the blade is not
tracking properly.
The top wheel shaft is hinged so the blade can be
tracked. Tilt the wheel by turning the tracking
adjustment screw using a medium screw driver.
(See illustration.)
a. If the bladel moves toward the front of the
band saw:
Turn the tracking adjustment screw clockwise
about 1/4 of a turn, as though you were
tightening it.
b. If the blade moves toward the back of the band
saw:
Turn the tracking adjustment screw counter­
clockwise about 1/4 of a turn as though you
were loosening it.
c. Check adjustment by turning wheel by hand.

3. The upper and lower blade guides support the
blade and keep it from twisting during operation.
Adjust blade guide support whenever blades are
changed or replaced with a different width.
4. Push the blade guide support toward the blade
and adjust the blade guides so they are about
1/32-inch from the deepest part of the blade
teeth This deep part is called a gullet. Tighten
the set screw locking the blade guide support.
Turn the upper wheel, by hand, checking the
position of the blade guide support.
NOTE: Letting the blade teeth hit the blade
guides while using the band saw will ruin the
blade. The set of the teeth and the sharpened
edge of the teeth would be damaged. Proper
adjustment of the upper and lower blade guide
assemblies will prevent this from happening.
Repeat procedure for lower blade guide support.
5. Slide the two blade guides evenly against the
sides of the blade. Do not push the blade guides
or pinch the blade guides against the blade.
Rotate the upper wheel by hand so the blade
travels downward. This leaves proper space for
blade. Make sure one guide is not further from
the blade than the other. Tighten both setscrews
with a 1/8-inch hex “L” wrench. Repeat proce­
dure for lower blade guides.
NOTE: The backup bearings support the blade
from the rear and will spin when the blade is
pushed against them while you are cutting. As
soon as you stop cutting, the bearings should
stop spinning.
