When wheels are aligned, or coplanar, the bandsaw cuts
straighter, with much less vibration, heat, and blade wear
because the blade is automatically balanced on the
wheel.
See
Figure 5
to better understand coplanarity.
If your bandsaw develops tracking problems that can't be
fixed by adjusting the upper wheel tracking knobs, then
check the wheel alignment before taking any other steps.
Verifying.Upper/Lower.Wheels.are.Coplanar
1.
DISCONNECT BANDSAW FROM POWER!
2.
With the blade on and properly tensioned, hold
a straightedge or a self-made "coplanarity gauge"
(
Figure.5
) close to the center of both wheels. Make
sure the straightedge or gauge fully extends across
the wheels as shown in
Figure.5
.
—
.
If the wheels are coplanar, the straightedge will
evenly touch the top and bottom of both wheels.
—
.
If the wheels are not coplanar, place the straight-
edge on the lower wheel first (ensuring that it
touches both the top and bottom rim), then adjust
the upper wheel tracking knob to make the upper
wheel parallel with the lower wheel.
— If the straightedge does not touch both wheels
evenly, the upper wheel needs to be shimmed or
the lower wheel needs to be adjusted.

1.
DISCONNECT BANDSAW FROM POWER!
2.
Make sure the top wheel is adjusted parallel with
the bottom wheel.
3.
With the straightedge touching both points of the
wheel that does not need to be adjusted, measure
the distance away from the incorrect wheel with a
fine ruler.
4.
Remove the blade from the saw, then remove the
wheel that needs to be shimmed.
5.
Determine how many shim washers you need to com-
pensate for the distance measured in
Step.3
and
place them on the wheel shaft.
6.
Replace the wheel, the original washers, and the
securing nut.

Blade Changes
To replace the blade, do these steps:
1.
DISCONNECT BANDSAW FROM POWER!
2.
Release the tension lever.
3.
Remove the table insert and the table pin. Adjust
the upper and lower guide blocks away from the
blade.
4.
Open the upper and lower wheel covers and slide
the blade off both wheels.
5.
Rotate the blade 90˚ and slide it through the slot in
the table.
6.
Slide the new blade through the table slot, ensuring
that the teeth are pointing down toward the table.
If the teeth will not point downward in any orienta-
tion, the blade is inside-out. Put on heavy gloves,
remove the blade, and twist it rightside-out.
7.
Slip the blade through the guides, and mount it over
the upper and lower wheels.
8.
Apply tension.
9.
Turn the tension knob until proper blade tension has
been reached according to the blade thickness scale
shown in
Figure.4
.
10.
Check and adjust the tracking.
11.
Adjust the upper/lower guide blocks and the support
bearings .
12.
Close the wheel covers.
13.
Replace the table insert and table pin, being sure
not to use excessive force when inserting the table
pin.

Always disconnect power to the
machine when changing blades.
Failure to do this may result in serious
personal injury.
All saw blades are dangerous and may
cause personal injury. To reduce the
risk of being injured, wear leather
gloves when handling saw blades.
