G0636X 17" Ultimate Bandsaw
Blade Tracking
Personal injury or death
can occur if the machine
starts while your hand
is touching the bandsaw
wheel during tracking
adjustments. Disconnect
power from the bandsaw
before performing blade
tracking adjustments.
The blade tracking is primarily affected by the
tilt of the upper wheel, also known as "Center
Tracking"; and the alignment of both wheels, also
known as "Coplanar Tracking." (For Coplanar
Tracking, see the
Wheel Alignment instructions
on Page 46.)
The wheels on this bandsaw were aligned at the
factory, so Center Tracking is the only adjust-
ment 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 (see Page
21).
3. Move the quick tension lever to the tightened
position and turn the blade tension handwheel
until the blade tension matches the mark on
the blade tension scale for the appropriate
blade thickness (
Figure 12).

The cast iron spokes may have sharp edges
and the blade teeth may extend beyond the
edge of the wheel, creating a laceration
hazard. Be careful when turning the wheels
by hand.
4. Open the upper wheel cover.
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 13 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 center tracked properly and no fur-
ther adjustments 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.
