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.
An over-tensioned blade increases the chance of
the blade breaking or wheel misalignment. Under-
tensioned blades wander excessively while cut-
ting and will not track properly during operation.
IMPORTANT: Always release blade tension when
storing machine. Storing the blade with high blade
tension for extended time period can deform
blade and weaken tensioning spring, reducing the
durability and accuracy of the machine.
To tension blade:
1.
Turn blade tension handle clockwise until
spring head is even with indicator bracket
(see Figure 25).

Note: Relying on the indicator to set tension pro-
vides a quick and easy method of achieving safe,
operational blade tension. If more precision is
required, consider using a blade tensioning gauge
(see Page 32).
