Blade Guides - Grizzly G1012 Instruction Manual

The blade should track so the flat portion of the
blade is centered on the upper wheel and tire.
Turn the wheel at least three full turns to ensure
that the blade is tracking in its final position. Your
bandsaw was adjusted and set at the factory so
that the blade will track in the center of the lower
band wheel when the blade is centered on the
upper wheel.
Now, set the final blade tension. It's difficult to
describe with accuracy what "final tension" should
be, owing to the large number of blades that will
work well in this saw.
As a general guide, press on the face of the blade
with your thumb as illustrated in Figure 12. If you
apply light to moderate pressure and can move
the blade over to the other side of the guard, you
can safely assume that final tension is OK. On the
other hand, if it is too tight, it will be hard to deflect
the blade and if it is very easy to deflect, your
blade is too loose.
Figure 12. Checking for proper blade tension.
The blade is sharp! Use extreme care when
making adjustments that require contact
between the bandsaw blade and your hand.

Blade Guides

Whenever changing a blade and/or adjusting ten-
sion and tracking, the upper and lower blade sup-
port bearings and guide-blocks must be re-
adjusted. Always loosen the setscrews and knobs
and adjust the assemblies away before installing
a new blade or making blade adjustments. After
blade tension and tracking are set correctly, re-
adjust the upper and lower support bearings and
guide-block assemblies into position.
UPPER BLADE GUIDE ASSEMBLIES
The support bearings back-up the blade during
the sawing operation. To adjust the upper bear-
ing, loosen the Allen
Adjustment Section. See Figure 10.). The upper
blade support bearing (Item 3) should be adjust-

The guide-blocks support the blade from both
sides. The steel guide-blocks should be set .002"
to .004" from the blade. See Figure 13. The
guide-block holder (Part #7) should be adjusted
so the front blocks are
