Blade Tensioning

To prolong blade life, release the tension on the blade if the machine will be idle for an extended period of time.

Proper blade tension reduces the risk of blade breakage and improves cutting performance.

1.DISCONNECT BANDSAW FROM POWER!

2.Turn the blade tension handwheel until you feel an average amount of resistance and the handwheel wants to stop. Then turn the handwheel an additional 12 turn.
