Tracking Blade
Blade "tracking" refers to where the blade rides on
the wheels as they rotate.
A blade that is tracking correctly runs cool-
er, reduces wear-and-tear on the machine, and
increases cutting performance. When tracking
correctly, the blade rides next to, but not against,
the wheel flange (see Figure 24).

flange.
Blade tension affects blade tracking. It is
important to make sure blade is properly
tensioned before tracking.
Adjust the blade tracking by adjusting the upper
and lower pairs of set screws shown in Figure 25.

When the upper or lower pair of set screws is
adjusted, the bottom of the upper wheel moves in
or out, which changes how the blade tracks.

Make sure the blade is properly tensioned, as
instructed on the previous page.
Open the upper wheel door.
Watch the position of the blade on the wheel
as you rotate the upper wheel by hand sev-
eral times.
— If the blade rides next to the wheel flange
without pressure and does not wander,
then no further adjustments are needed.
— If the blade does not ride next to the wheel
flange or it wanders, proceed to the next
step.
Loosen the four locking set screws (see
Figure 25).
Rotate the upper wheel by hand several
times, watching the blade position on the
wheel.
Adjust the upper and lower pairs of set screws
(see Figure 25) an equal amount—to tilt the
upper wheel in or out—until the blade rides
next to the wheel flange without pressure and
without wandering across the wheel. Adjust
each pair of screws in small increments, then
repeat Step 6.
— If the blade is tracking correctly, no further
adjustments need to be made. Proceed to
Step 8.
— If the blade is not tracking correctly, repeat
Steps 6–7 until the blade is tracking
correctly.
Tighten all four locking set screws and
recheck the tracking to make sure it did not
change. If it did, repeat Steps 5–8.
