Test Run - Grizzly G0970 Owner's Manual

Note: When adjusting blade tracking for test
run in this procedure, blade must have a rea-
sonable amount of tension to simulate oper-
ating conditions. After test run is successfully
completed, you will perform a thorough ver-
sion of the following steps to more accurately
tension the blade.
Pull blade tension quick-release lever down
3.
(as viewed from rear of machine) to apply
tension to blade (see Figure 32).
Use tension knob on top of bandsaw to bring
4.
upper edge of indicator block to appropriate
blade tension scale mark for blade width (see
Figure 32).
Note: A ⁄ " wide blade is shipped with the

machine when new.

wheel by hand several times. Watch where
blade rides on wheel crown (see Figure 31
for an illustration of this concept).
— If blade rides in center of upper wheel and
is centered on wheel crown, it is properly
tracking and no adjustment is necessary—
proceed to Test Run on Page 23.
— If blade is NOT properly tracking, proceed
to Step 6.
