Blade Tension Gauge - Grizzly G0970 Owner's Manual

Shimming a Wheel
A wheel that is parallel with the other wheel, but
is not coplanar, must be shimmed by the distance
that it is not in the same plane with the other
wheel.
Tip: Thin washers work well for shimming the
wheel because they can easily be stacked to get
the desired height.
To shim a wheel:
Adjust upper wheel tracking so that it is paral-

that does not need to be adjusted, measure
distance away from other wheel with a fine
ruler, as shown in Figure 77. Distance mea-
sured with ruler is distance this wheel must
be shimmed.

many shims as necessary to correct the gap
measured in Step 3 onto the wheel shaft.
Re-install wheel and secure it in place.

Note: The first time you get wheels coplanar,
place a mark on each wheel where you held
the straightedge, then use this position again
in the future if you need to repeat the proce-
dure. This assures repeated accuracy every
time you adjust the wheels.
Blade Tension
Gauge
The Model G0970 uses a tension gauge system
that helps users ensure they are applying consis-
tent and appropriate tension to the bandsaw blade
based on its size. Different blade sizes require
different amounts of tension to perform optimally
and produce accurate cuts.
Keep in mind that proper tensioning is crucial for
safety and performance. Too little tension can
result in poor cutting performance and increased
risk of blade breakage, while excessive tension
can lead to premature blade wear and strain on
the bandsaw machine.
Always follow the manufacturer's guidelines and
recommendations for tensioning your bandsaw
blade, and make sure to properly maintain and
inspect the blade and machine for safe and effec-
tive operation.
The blade tensioner may need to be adjusted for
one of the following reasons:
• The blade tension quick-release lever will not
move to the right position when the tension
scale is correctly adjusted for the installed
blade.
• You have installed a blade of a different length
and the tensioner needs to be adjusted.
