G0513 Series Bandsaws (Mfd. Since 08/22)
-33-
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 the blade is properly tracking as
instructed in the
Initial Blade Tracking on
Page 27.
3. Raise guide post all the way and move upper
and lower guide bearings away from blade
(refer to
Page 35 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 on Pages 34–35.
The Deflection Method
Fine Tune Tracking
During setup, the blade was tracked without the
machine connected to power (refer to
Page 27).
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 44–45).
Figure 44. Example of blade, viewed through
tracking window.
3. If necessary, loosen tracking control lock
lever and use tracking control knob (see
Figure 45) to adjust the blade so it tracks on
the center of the wheel.
4. Tighten tracking control lock lever (see Figure
45) to secure setting, then turn machine OFF.
