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

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.

sides of the blade. Do not push the blade guides
or pinch the blade guides against the blade.

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.
