CENTER TRACKING
Wheel
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 29).
Figure 29. Blade centered on crown of wheel.
3. Pull blade tension quick-release lever down
(as viewed from rear of machine) to apply
tension to blade (see
Figure 30).
4. Use tension knob on top of the bandsaw to
bring upper edge of indicator block to appro-
priate blade tension scale mark for blade
width (see
Figure 30).
Note: A
3
⁄
8
" wide blade is shipped with the
machine when new.
5. Open upper wheel cover, rotate upper wheel
by hand several times and watch where
blade rides on wheel crown (see
Figure 29
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 you are done with this proce-
dure—proceed to
Test Run on page 25.
— If blade is NOT properly tracking, then con-
tinue with this procedure to adjust it.
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
Wheel Alignment on
Page 54 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.
To set blade center tracking:
1. DISCONNECT MACHINE FROM POWER!
2. Adjust upper and lower blade guides away
from blade (refer to Adjusting Blade Guide
Bearings on Page 28 for detailed instruc-
tions).
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.
