Tensioning Blade

A properly tensioned blade is essential for mak-
ing accurate cuts, maximizing blade life, and
making other bandsaw adjustments. However, a
properly tensioned blade will not compensate for
cutting problems caused by excessive feed rate,
hardness variations between workpieces, and
improper blade selection.
Optimal cutting results for any type of workpiece
are achieved through a combination of correct
blade selection, proper blade tension, properly
adjusted blade guides and other bandsaw compo-
nents, and using an appropriate feed rate.
Improper blade tension is unsafe, produces inac-
curate and inconsistent results, and introduces
unnecessary wear on bandsaw components.
Over-tensioning the blade increases the chance
of the blade breaking or wheel misalignment.
Under-tensioned blades wander excessively
while cutting and will not track properly during
operation.
To tension blade:
DISCONNECT MACHINE FROM POWER!

(refer to Blade Tracking on Page 22 for
