11. Position blade at center of upper and lower
wheels.
12. Reinstall dust block (J, Figure 7-8) and table
slot handle (HP6, Figure 5-3).
13. Before operating band saw, the new blade must
be tensioned and tracked, in that order. Find
instructions for tensioning and tracking the
blade in
sections 7.7 and 7.9
.
14. The blade guides must also be set properly
according to instructions in
sections 7.11
through 7.13.
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.
