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
Initial Blade Tracking subsec-
tion on
Page 25.
3. Raise guide post all the way, and move upper
and lower guide bearings away from blade
(refer to
Page 31 for more information).
4. Engage blade tension quick-release lever to
apply tension to blade.
5. Connect bandsaw to power, then turn it ON.
6. Use blade tension handwheel to slowly
decrease blade tension until you see 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 31–32.
The Flutter Method
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
Initial Blade Tracking subsec-
tion on
Page 25.
3. Raise guide post all the way and move upper
and lower guide bearings away from blade
(refer to
Page 31 for more information).
4. Engage blade tension quick-release lever to
apply tension to blade.
5. Using moderate pressure, push center of
blade sideways.
— If blade deflects approximately
1
⁄
4
", it is
properly tensioned. Proceed to
Step 6.
— If blade deflects less than
1
⁄
4
", it is over-ten-
sioned. Rotate blade tension handwheel
counterclockwise two full turns and repeat
Step 5.
— If blade deflects
1
⁄
4
" or more, blade is not
properly tensioned. Rotate blade tension
handwheel clockwise to incrementally ten-
sion blade, and repeat
Step 5 until blade
is properly tensioned.
6. Adjust blade guides as described in Adjusting
Blade Support Bearings and Adjusting
Blade Guide Bearings on Pages 31–32.
