2. Open the upper and lower doors and
remove the blade.
3. Unscrew the hex nut from the lower wheel
shaft and remove the lower wheel.
4. Loosen the motor lock handle.
5. Raise the motor lift handle and re-tighten
motor lock handle to hold motor in raised
position.
6. Remove old belt and install new one,
making sure it seats properly in the pulley
grooves.
7. Loosen motor lock handle and allow motor
to lower.
8. The weight of the motor itself should
generally produce the proper tension for the
belt. Check the tension by pushing with
moderate pressure against the center of the
belt (Figure 40). An adequately tensioned
belt will deflect about 1/2”. If tension isn’t
strong enough, push down on the motor.
9. Tighten motor lock handle, reinstall lower
wheel, and install hex nut securely on shaft.
10. Re-check blade tension and tracking before
operating the saw.
Wheel Brush
Refer to Figure 41.
The brush located next to the lower wheel must
contact the tire to clear the tire of dust and
debris before it touches the blade. Use the two
phillips head screws to make any adjustments to
the brush position.
Insert Block
Refer to Figure 41.
The insert block should remain in position to
prevent dust and chips from falling onto the
lower wheel. If it should ever become damaged,
it should be replaced. Some band saw users
make their own out of scrap wood.
Operating Controls
Start/Stop
Power Indicator Light – The start switch has a
power indicator lamp which is on whenever
there is power connected to the Band Saw,
not just when the Band Saw is running. Do not
assume that no light means there is no power to
the machine. If the bulb is bad, there will be no
indication. Always check before use.
