-20- G1019 14'' Bandsaw
Blade Tension
Proper blade tension is important for optimum
bandsaw performance. See Figure 24 for band-
saw tension controls. To increase blade tension,
turn the blade tension knob clockwise. To reduce
blade tension, turn the blade tension knob coun-
terclockwise.
Since a variety of blades will work well with this
saw, final blade tension ultimately depends on the
type and size of blade you use. Thinner blades
require less tension than wide blades. Too much
tension will result in blade breakage. A properly
tensioned blade will track the cutting line accu-
rately and the cut will be smoother.
Proper blade tension can best be achieved by
determining the amount of blade deflection:
1. Ensure that the power is off and the saw is
unplugged. Raise the upper guide assem-
bly all the way and lock in place.
2. Press, with moderate pressure, on the face
of the blade with your thumb.
3. Turn the tensioning knob to adjust the
amount of tension. The blade should deflect
about
1
/4".
If the tension seems correct, make all of the other
adjustments to the saw and test run. If the blade
is not cutting properly, the tension may be incor-
rect and readjustment may be needed.
Remember to reduce the blade tension when the
bandsaw is not in use, this will help to prevent
premature breakage of the blade and/or the rub-
ber tires.
Now, direct your attention to the controls located
around the backside of the upper cover of the
saw. See Figure 24.
F. This knob is used to control blade tension.
Turning clockwise increases tension; coun-
terclockwise decreases tension.
G. This knob controls blade tracking. Note that
the knob has a locknut to lock tracking in
place.
H. This handle locks the upper blade guide
assembly in position. The upper guide
should be adjusted to within
1
⁄4" of the work-
piece for optimum blade support. Do not
operate bandsaw without locking the guide
post handle.

Do not make adjustments while the band-
saw is running. Ensure that the switch is off,
power is disconnected, and moving parts
have stopped before making adjustments.
Check adjustments while power is still dis-
connected by manually turning the bandsaw
wheel by hand.
