9. Reinstall dust block, table insert and table pin.
(The table pin prevents deflection of table along
blade slot.)
10. Before operating band saw, the new blade must
be tensioned and tracked, in that order. Refer to
sect. 5.9 and 5.10.
11. The blade guides must also be set properly
according to instructions in sect. 7.7 through
7.10.
5.9 Blade tension
Refer to Figures 5-7 and 5-8.
Blade tension should be checked following blade
replacement, and periodically as the blade stretches
from use.
1. Lower tension lever (D, Figure 5-7) to tension
position.
2. Set proper blade tension by rotating handwheel
(E, Figure 5-7), clockwise to tighten,
counterclockwise to loosen.
3. The gauge (F, Figure 5-8) indicates
approximate tension according to blade width in
inches. Initially, set blade tension to correspond
to width of blade. As you become familiar with
the saw, you may find it necessary to alter blade
tension from the initial setting.
Keep in mind that too little or too much blade tension
can cause blade breakage and/or poor cutting
performance.
Tip: When the band saw is not being used, raise
tension lever (D) to release position – this will
prolong the life of blade and tires.

5.10 Blade tracking
Refer to Figures 5-7 and 5-8.
After proper tensioning, the blade must be tracked.
“Tracking” refers to position of blade on the wheels
while machine is in operation. Tracking should be
checked periodically, and is mandatory after every
blade change. Blade tracking is done initially by
hand with machine disconnected from power.
1. Disconnect band saw from power source.
2. Blade must be correctly tensioned (sect. 5.9).
Lower blade tension lever to tension position.
3. Back off blade guides so they will not interfere
with blade movement.
4. Loosen guide post locking knob (G
1
, Figure 5-
7) and use handwheel (G
2
) to lower guide post
until you can see blade through tracking window
(H).
5. Open upper door to expose wheel.
6. Rotate wheel by hand, observing position of
blade through tracking window. The blade
should ride approximately at center of tire
(Figure 5-9).
Figure 5-9
7. If blade tends to migrate toward left or right
edge of wheel, loosen locking handle (J
1
, Figure
5-7) counterclockwise, and rotate tracking knob
(J
2
) with your right hand while continuing to
rotate wheel with your left.
