7.7 Blade tension
Blade tension is set with the blade tension
handwheel (L, Figure 7-10) and is performed
following blade replacement and periodically as the
blade stretches from use.
Disconnect machine from
power source before making any adjustments.
Refer to Figures 7-9 and 7-10.
1. Place tension lever (K, Figure 7-9) in Full Tension position.
2. Set blade tension by rotating handwheel (L)
according to the arrow directions shown in
Figure 7-10, clockwise to tighten,
counterclockwise to loosen.
3. The gauge (M) indicates approximate tension
according to the width of the blade in inches.
Initially, set the blade tension to correspond to
the width of your blade.
As you become familiar with the saw, you may find
it necessary to change the 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, place
tension lever to Partial Tension position – this will
prolong the blade’s life.
7.8 Adjusting blade tension lever
The blade tension lever has an adjustment screw or
stop bushing that allows you to adjust how much
tension is released when lever is used.
To adjust tension lever:
1. Disconnect machine from power source.
2. Move lever to Blade Release position and
remove blade.
3. Move tension lever to Full Tension position.
4. Move stop bushing (Figure 7-11) until gap
between stop bushing and wheel shaft hinge is
1/8 to 3/16 in.

7.9 Blade tracking
O
N
P
R
Refer to Figures 7-12 and 7-13.
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 by hand with
machine disconnected from power.
1. Disconnect machine from power source.
2. Blade must be correctly tensioned (sect. 7.7).
3. Make sure blade guides and other parts of
machine will not interfere with blade movement.
Use handwheel (N) to lower guide post until you
can see blade through tracking window (O,
Figure 7-12).
4. Set blade tension lever initially to Partial Tension-Idle/Tracking position.
8. Loosen locking handle (P, Figure 7-12) and
slightly rotate tracking knob (R) with your right
hand while continuing to rotate wheel with your
left. Observe blade through tracking window.
Rotating knob clockwise will cause blade to
move toward rear edge of wheel. Rotating knob
counterclockwise will cause blade to move
toward front edge of wheel.
IMPORTANT: This adjustment is sensitive;
perform in small increments and give blade time
to react to changes.
9. When blade is tracking in center of wheel, retighten locking handle (P), and close upper
door.
10. Move tension lever to Full Tension position, and
connect band saw to power. Turn it on for a brief
time to observe blade in action through tracking
window.
11. If further adjustments are needed, disconnect
from power and repeat above procedure.
7.10 Overview – bearing adjustments
Thrust (back support) bearings are located behind
saw blade and provide support to back of blade
when saw is in operation.
Guide bearings are located on either side of saw
blade and provide stability for the blade when saw
is in operation. These bearings rotate on an
eccentric shaft so distance from blade can be
adjusted for optimal performance.
Figure 7-12
5. Open upper door to expose wheel.
6. Rotate wheel by hand, observing position of
blade through tracking window. As you rotate
wheel, move tension lever to Full Tension
position. The blade should continue to ride upon
center of tire (Figure 7-13).

7. If blade tends to move toward edge of wheel,
set lever to Partial Tension-Idle/Tracking.
7.11 Upper blade guides
Unplug machine from power
source before making any adjustments! Blade
teeth are sharp – use care when working near
blade. Failure to comply may cause serious
injury.
The bearing guides should be set so that contact
between blade and guides will occur only when
blade is under pressure from a workpiece. To adjust
upper bearing guides for proper blade control,
proceed as follows.
Refer to Figures 7-14 and 7-15.
1. Disconnect machine from power source.
2. Blade must already be tensioned and tracking
correctly. Place tension handle in Full Tension
position.
3. Lower guide post until upper guide bearings are
a few inches off table. (The reason for this will
be evident later in sect. 7.15)
4. Loosen lock knob (A, Figure 7-14).

5. Slide entire guide bracket until front of guide
bearings are about 0.015” (1/64”) behind the
blade’s gullet (curved area at base of tooth).
See Figure 7-16.
Figure 7-16
6. Tighten lock knob (A) to secure this position.
7. Loosen lock knob (B) for either of the front guide
bearings.
8. The guide bearing rotates on an eccentric shaft.
Adjust guide bearing by rotating the knurled
knob (C) until guide bearing is approximately
0.004” from blade. A quick way to achieve this
spacing is by placing a single thickness of a
crisp dollar bill (a dollar bill is approximately
0.004” thick) between blade and guide bearing.
Adjust guide bearing until it just lightly grips the
dollar bill.
NOTE: Do not force guide bearing against side
of blade. It should generally only make contact
with blade when there is pressure from the
cutting operation.
9. Tighten lock knob (B).
10. Repeat process for opposite guide bearing.
7.12 Upper thrust bearing
Refer to Figures 7-14 and 7-15.
The thrust bearing prevents backward deflection of
blade during cutting. A groove in the bearing surface
helps stabilize the moving blade.
1. Loosen lock knob (D) and slide thrust bearing
up to back of blade.
2. Adjust thrust bearing until space between
groove bottom and back edge of blade is
approximately 0.015” (1/64”). Tighten lock knob
(D).
3. If lateral adjustment of bearing is needed to
align groove with blade, loosen set screw (E) at
front of bearing assembly, and shift bearing as
needed. Retighten set screw.
4. Make sure all lock knobs on upper guide
bearing assembly are tightened when
adjustments are finished.
7.13 Lower blade guides
Unplug machine from power
source before making any adjustments! Blade
teeth are sharp - use care when working near
saw blade. Failure to comply may cause serious
injury.
Refer to Figures 7-17 and 7-18.
1. Disconnect band saw from power source.
2. Open lower door and swing lower guard out of
the way.
3. Adjust lower guide bearings and lower thrust
bearing below table in similar manner to that of
upper guide and thrust bearings.
4. Movement summary: Loosen lock knob (F) to
move entire guide bearing assembly. Loosen
lock knob (G) and rotate knob (H) to adjust
guide bearing in relation to blade. Thrust
bearing is controlled by locking knob (J) and
lateral adjustment by set screw (K).
5. Make sure all knobs and handles are tightened
after adjustments are complete.
