8. Guide new blade through table slot. Place
blade loosely in the upper and lower blade
guides. Make sure blade teeth point down
toward table, and toward the front of the
saw. (If the teeth will not point down, no
matter how you orient the blade, then the
blade is twisted inside-out. Twist it into
correct position and re-install it.)
9. Position blade at the center of the upper and
lower wheels.
10. Re-install table insert (A) and table pin (B).
11. Before operating the band saw, the new
blade must be tensioned and tracked, in that
order. Find instructions for tensioning and
tracking the blade under “Blade Tension”
and “Blade Tracking.” The blade guides
must also be set properly according to the
instructions on pages 19 and 20.
Blade Tension
Refer to Figure 25.
1. Disconnect machine from power source.
2. Back off upper and lower guide bearings to
eliminate any contact with the blade.
3. With the blade centered on the wheels,
move the quick tension lever to “Full
Tension” position, as shown in Figure 25.
NOTE: You will be able to feel the lever fall
into each position.
4. Rotate the tension handwheel (C) until the
scale pointer (D) reaches the appropriate
measurement for the width of the blade.
TIP: Use the band saw’s gauge setting initially.
As you become familiar with the machine and
with the different properties of band saw blades,
you may find it necessary to change the blade
tension from the initial setting. Keep in mind that
not only changes in blade width, but also the
type of material being cut will have an effect on
blade tension. Too little or too much blade
tension can cause blade breakage and/or poor
cutting performance.
Make a note of the specific tension setting for a
particular blade. The tension can then be re-set
quickly when band saw operations are resumed.
IMPORTANT: When the band saw is not being
used, move the quick tension lever to “Partial
Tension-Idle/Tracking” position. This will prolong
the life of the blade and tires, and reduce load
on wheels, bearings and other components.
