Blade Breakage
Many conditions may cause a bandsaw blade to break. Blade breakage is unavoidable, in some cases, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to. Blade breakage is also due to avoidable circum- stances. Avoidable breakage is most often the result of poor care or judgement on the part of the operator when mounting or adjusting the blade or support guides.
The most common causes of blade breakage are:
(1)faulty alignment and adjustment of the guides,
(2)forcing or twisting a wide blade around a curve of short radius, (3) feeding the workpiece into the blade too fast, (4) tooth dullness or absence of sufficient set, (5) excessive tension, (6) top blade guide assembly set too high above the work piece, (7) using a blade with a lumpy or improp- erly finished braze or weld and (8) continuously running the bandsaw when not in use.

1.Unplug the bandsaw!
2.Release tension on the blade by turning the tension control knob
3.Remove the table insert and the table pin. Adjust the upper and lower guide blocks away from the blade.
Wear gloves and safety goggles when han- dling blades. Coiled blades spring open as they are uncoiled and could cause deep punctures or lacerations.
4.Open the upper and lower wheel covers and slide the blade off both wheels. Use caution Ñ the blades are sharp!
5.Rotate the blade 90û so it will slide through the slot in the table.
