Adjustment
Overview
The bandsaw is a very versatile cutting machine.
However, it has multiple components that must be
properly adjusted for the best results.
For practical and safety reasons, some adjust-
ments and test operations must be performed
before performing other necessary adjustments.
Below is an overview of all the adjustments and
the order in which they should be performed:
Blade Tracking
1.
Test Run
2.
Tensioning Blade
3.
Adjusting Blade Guides & Support Bearings
4.
Calibrating Table Tilt
5.
Aligning Table

Blade Tracking
"Tracking" refers to how the blade rides on the
bandsaw wheels. Proper tracking is important
for maintaining bandsaw adjustments, achiev-
ing correct blade tension, and cutting accurate-
ly. Improper tracking reduces cutting accuracy,
causes excess vibrations, and places stress on
the blade and other bandsaw components. The
shape of the wheels and the orientation of the
wheels in relation to each other determine how
the blade tracks.
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 performing
blade tracking adjustments.

Bandsaw wheels are either flat or crowned and
both shapes track differently. This bandsaw has
crowned wheels. As the wheels spin, a properly
tracking blade naturally tracks at the center of the
wheel (see Figure 31).

Blade tracking is primarily affected by the tilt of
CENTER TRACKING
the upper wheel, known as "center tracking."
However, the alignment of both wheels plays an
important part as well (see Wheel Alignment on
Page 48 for more details).
The wheels on this bandsaw were aligned at the
factory, so center tracking is the only adjustment
that needs to be checked/performed when the
saw is new.
Note: The Model G0970 is equipped with a gear
reducer, which makes turning the wheels by hand
very difficult. To make blade tracking adjustments
that require turning the wheels by hand, release
the V-belt tension by raising the motor and lock-
ing it in the raised position. Refer to Tensioning
V-Belt on Page 46 for detailed instructions.
To adjust blade tracking:
DISCONNECT MACHINE FROM POWER!
1.
Adjust upper and lower blade guides away
2.
from blade (refer to Adjusting Blade Guides
& Support Bearings on Page 25 for
detailed instructions).
