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
subsection on Page 22.
3. Raise guide post all the way and move upper
and lower guide bearings away from blade
(refer to Page 30 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-tensioned. 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
tension 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 29–30.
The Deflection Method
Fine-Tune Tracking
During setup, the blade was tracked without the
machine connected to power (refer to Page 22).
In this procedure, the bandsaw is turned ON to
perform fine tuning of the tracking. Make small
changes with the blade tracking knob as you
monitor the effect on the blade tracking.
To fine-tune blade tracking:
1. Close wheel covers and turn bandsaw ON.
2. Observe blade tracking path through clear
tracking window on right edge of bandsaw
(see Figures 33–34).
Figure 33. Example of blade, viewed through tracking Figure 33. Example of blade, viewed through tracking
window. window.
3.
If necessary, loosen tracking control lock
lever and use tracking control knob (see
Figure 34) to adjust the blade so it tracks on
the center of the wheel.
4. Tighten tracking control lock lever (see
Figure 34) to secure setting, then turn
machine OFF.
