Initial Blade Tracking - Grizzly G0513 SERIES Owner's Manual

Initial Blade Tracking

Serious personal injury can
occur if the machine starts
while your hand is touch-
ing the bandsaw wheel dur-
ing tracking adjustments.
Disconnect power from the
bandsaw before perform-
ing blade tracking adjust-
ments.
Blade tracking is primarily affected by the tilt of
the upper wheel, known as "center tracking."
however, the alignment of both wheels plays an
important part as well (see the Aligning Wheels
instructions on Page 65 for more details).
the wheels on this bandsaw were aligned at the
factory, so center tracking is the only adjustment
that needs to be performed when the saw is
new.
To center track the blade:
1. disCoNNECt BaNdsaW FroM poWEr!
2. Make sure the upper and lower blade guides
are adjusted away from the blade.
3. open the upper wheel cover.
4. Engage the quick tension lever, then turn the
blade tension handwheel until the tension
scale (see Figure 30) is between 4 and 6.

The wheels may have sharp edges and the
blade teeth may extend beyond the edge,
creating a laceration hazard. Be careful
when turning the wheels by hand.
5. spin the upper wheel by hand at least three
times and watch how the blade rides on the
crown of the wheel. refer to Figure 31 for an
illustration of this concept.
— if the blade rides in the center of the upper
wheel and is centered on the peak of the
wheel crown, then the bandsaw is already
tracking properly and no further adjust-
ments are needed at this time.
— if the blade does not ride in the center of
the upper wheel and is not centered on the
peak of the wheel crown, then continue
with the following steps.
