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 (refer
to
Initial Blade Tracking on Page 23 for
instructions).
3. Raise guide post all the way up and move
upper and lower guide bearings away from
the blade.
4. Set blade tension quick release lever to apply
tension to the blade.
5. Using moderate pressure, push the center of
blade sideways.
—If blade deflects approximately
1
⁄
4
" it is
properly tensioned. Proceed to
Step 7.
—If blade deflects less than
1
⁄
4
" it is over-
tensioned. Turn blade tensioning knob
counter clockwise two full turns and repeat
Step 6.
—If the blade deflects
1
⁄
4
" or more, it is under-
tensioned. Apply tension to blade incre-
mentally and repeat
Step 6 until properly
tensioned.
6. Re-adjust blade guides (refer to Adjusting
Blade Support Bearings and Adjusting
Blade Guide Bearings on Pages 27– 28 for
instructions).
When using different size blades, the blade
tensioning system may need to be reset for
correct operation.
The Deflection Method
Adjusting Blade
Support Bearings
The support bearings are positioned behind the
blade on the blade guides and prevent it from
deflecting backward during cutting operations.
Proper adjustment of the support bearings is an
important part of making accurate cuts and keeps
the blade teeth from coming in contact with the
blade guides while cutting, which will bend the
"tooth set" of the blade teeth and ruin the cutting
effectiveness of the blade.
There are support bearings on the upper and
lower blade guide assemblies. Both adjust in the
same manner.
IMPORTANT: Make sure the blade is tracking
and tensioned correctly before performing this
procedure.
