Deflection Method
The deflection method is more subjective than the
flutter method. Each blade deflects differently and
every user must determine what "moderate pres-
sure" means. The following are general guide-
lines for tensioning the blade with the deflection
method.
To tension the bandsaw blade:
1. DISCONNECT BANDSAW FROM POWER!
2. Make sure the blade is properly tracking as
instructed in the Initial Blade Tracking sec-
tion on Page 25.
3. Raise the guide post all the way, and move
the upper and lower blade guides away from
the blade.
4. Engage the blade tension quick-release lever
to apply tension to the blade.
Whenever changing a blade or adjusting
tension and tracking, the upper and lower
blade support bearings and blade guides
must be properly adjusted before perform-
ing cutting operations.
5. Using moderate pressure, push the center of
the blade sideways.
— If the blade deflects approximately
1
⁄4", it is
properly tensioned. Proceed to Step 6.
— If the blade deflects less than
1
⁄4" it is
over-tensioned. Turn the blade tensioning
handwheel counterclockwise two full turns
and repeat this step.
— If the blade deflects more than
1
⁄4", the
blade is under-tensioned. Apply tension to
the blade a small amount and repeat this
step until the blade is properly tensioned.
6. Re-adjust the blade guides as described in
Adjusting Blade Guides beginning on Page
33 for your model bandsaw.
