Aligning Blade Support Bearings - Grizzly G0701 Owner's Manual

Deflection 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 tracking properly as
instructed in Initial Blade Tracking on Page
19.
3.
Use the guide post elevation control to raise
the guide post all the way up, then move the
upper and lower guide/support bearings as
far away from the blade as possible (refer to
Adjusting Blade Guide Bearings on Page
28 for detailed instructions).
4. Move the blade tension quick release lever all
the way to the right (as viewed from the rear
of the machine) to apply tension, then rotate
the tension handwheel until the mark on the
blade tension scale matches the one for the
blade width (see Figure 23).
5. Using moderate pressure, push center of
blade sideways.
— If blade deflects approximately
properly tensioned. Proceed to Step 6.
— If blade deflects less than
sioned. Rotate blade tension handwheel
counterclockwise two full turns and repeat
Step 5.
— If blade deflects
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 Aligning
Blade Support Bearings on Page 25 and
Adjusting Blade Guide Bearings on Page
28.

Aligning Blade
Support Bearings
Proper alignment of the blade guide and support
bearings with the blade is an important part of
making accurate cuts. When correctly aligned,
the guide bearings support but do not contact the
blade teeth, and the support bearing keeps the
blade from deflecting backwards with the force
of cut.
Upper Blade Bearings
1.
Make sure the blade is properly tensioned
(Page 24) and tracking correctly (Page 19).
2. DISCONNECT MACHINE FROM POWER!
3.
Familiarize yourself with the upper blade
bearing controls shown in Figures 24–25.
