The deflection method is much more subjective
than the flutter method. Each blade will deflect
differently and every user will determine what
"moderate pressure" means. The following are
general guidelines for tensioning the blade with
this method.
To tension bandsaw blade using deflection
method:
1. DISCONNECT MACHINE FROM POWER!
2. Make sure blade is properly tracking as
instructed in Blade Tracking subsection on
Page 17.
3. Raise guide post all the way and move upper
and lower guide bearings away from blade.
4. Engage blade tension quick-release lever to
apply tension to blade.
5. Using moderate pressure, push center of the
blade sideways.
—If the blade deflects approximately
1
⁄
4
", it is
properly tensioned. Proceed to
Step 7.
—If the blade deflects less than
1
⁄
4
", it is over-
tensioned. Turn the blade tensioning knob
counter clockwise two full turns and repeat
Step 6.
—If the blade deflects
1
⁄
4
" or more, the blade
is not properly tensioned. Apply tension to
the blade incrementally and repeat
Step 6
until properly tensioned.
6. Adjust blade guides as described in Adjusting
Blade Support Bearings and Adjusting
Blade Guide Bearings on Pages 22–23.
Using the flutter method, you intentionally loosen
the blade until it just passes the point of being
too loose (when it begins to flutter). Then you
gradually tighten the blade until proper tension is
reached.
To tension bandsaw blade using flutter
method.
1. DISCONNECT MACHINE FROM POWER!
2. Make sure blade is properly tracking as
instructed in
Blade Tracking subsection on
Page 17.
3. Raise guide post all the way, and move upper
and lower guide bearings away from blade.
4. Engage blade tension quick-release lever to
apply tension to blade.
5. Connect bandsaw to power, then turn it ON.
6. Using blade tension adjustment knob, slowly
decrease blade tension until you see the
blade start to flutter.
7. Slowly increase tension until blade stops flut-
tering, then tighten blade tension adjustment
knob an additional
1
⁄
8
to
1
⁄
4
of a turn.
8. DISCONNECT MACHINE FROM POWER!
9. Adjust blade guides as described in Adjusting
Blade Support Bearings and Adjusting
Blade Guide Bearings on Pages 22–23.
