Symptom Possible Cause Possible Solution
Blade tracks
incorrectly, or
comes off wheels. 1. Feed rate is too fast/wrong TPI.
2. Blade tracking requires adjustment.
3. Blade is bell-mouthed.
4. Blade is dull, wanders, and gets pinched in
the cut.
5. Rubber tire(s) on wheel damaged, glazed,
or worn.
6. Blade tension is too loose.
7. Blade guides need adjustment.
8. Incorrect blade for bandsaw operation.
9. The blade has insufficient support.
10. Metal chip buildup on wheels.
1. Reduce feed rate/decrease blade TPI.
2. Adjust blade tracking (
Page 23).
3. Install new blade, and regularly remove tension
from blade when not in use ( Page 23).
4. Replace blade, re-secure the workpiece from
shifting.
5. Replace or dress rubber tire(s) (
Page 46).
6. Increase blade tension (
Page 23).
7. Adjust blade guides ( Page 25).
8. Install correct blade for machine (
Page 34).
9. Tighten the blade guide as close to the workpiece
as possible.
10. Clean metal chips from wheels.
The cut is crooked,
the blade wanders,
slow cuts, or shows
overheating on one
side of the cut or the
blade. 1. Feed rate is too fast.
2. Too much side pressure when feeding
workpiece.
3. Blade is loading up.
4. Blade installed backwards.
5. Dull blade; missing teeth.
6. Blade too wide for size of radius being cut.
7. The blade speed is wrong.
8. The blade tracking is wrong.
1. Reduce the feed rate.
2. Feed workpiece straight into the blade.
3. Install a blade with more suitable TPI or different
style of teeth.
4. Reverse blade if necessary.
5. Replace blade (
Page 34).
6. Install a smaller width blade.
7. Adjust blade speed as required.
8. Adjust the blade tracking (

3. Replace welder transformer.
Weld is mis-aligned. 1. Debris or flash on weld clamps or blade.
2. Blade ends not cut off square.
3. Blade ends not evenly butted in clamps.
4. Clamping pressure not set correctly.
1. Remove debris, oily substances, or flash from weld
clamps and blade.
2. Use blade shear to cut blades; grind ends together.
3. Make sure blade ends are evenly butted against
each other before securing with lock levers.
4. Set clamping pressure correctly (
Page 39).
Weld not complete
(has holes) 1. Blade ends not clamped properly.
2. Blade ends not even with each other.
1. Make sure blade ends are evenly butted against
each other in clamps; use correct clamping
pressure (
Page 39).
2. Use blade shear to cut blades; grind ends together.
Weld breaks or is
brittle. 1. Weld not correctly annealed.
2. Weld is ground too thin.
3. Debris or oil in weld. 1. Correctly perform annealing procedure ( Page 40).
2. Only grind flash even with blade body.
