-10- G1258 20" Bandsaw
SECTION 5: ADJUSTMENTS
Tracking
To adjust the tracking:
1. Disconnect the bandsaw from the power
source and open the top and bottom wheel
covers. Adjust the upper and lower guide
assemblies away from the blade.
2. Loosen the lock nut on the tracking knob.
See
Figure 3. Rotate the upper wheel by
hand and adjust the tracking knob (turn the
tracking knob clockwise to track the blade in,
counterclockwise to track out) until the flat
body of the blade tracks in the center of the
upper wheel. Turn the wheel at least three
full turns to ensure that the blade is tracking
in its final position.

Use extreme care when turning the band-
saw wheel. The upper wheel may have
sharp edges and any procedures which
require work in close proximity to the band-
saw blade could result in serious injury.
Tension
Final blade tension ultimately depends on the
type and size of blade you use. To adjust the ten-
sion:
1. Press, with moderate pressure, on the face
of the blade with your thumb.
2. Turn the tension wheel until the blade
deflects about
1 ⁄
4
". See Figure 4.
3. Make the other adjustments to the saw and
test run it. If the blade is not cutting properly,
the tension may need to be increased.
Remember, thin blades require less tension
than wide blades.
4. Reduce the blade tension when the bandsaw
is not in use. This will help prevent premature
wear or breakage of the blade and/or rubber
tires.
