and wheel damage.

6.Re-tension the blade (refer to the following Blade Tensioning section).

7.Rotate the top wheel clockwise by hand several times to make sure the blade tracks evenly without wandering across the wheel surface.

Note: If the blade wanders across the wheel and away from the flange, the wheel alignment may need to be adjusted. Refer to Blade Tracking on Page 35 for detailed instructions.

8. Adjust the upper and lower blade guides

(refer to Adjusting Blade Guides on

To replace the blade:

1.DISCONNECT BANDSAW FROM POWER!

2.Open the upper and lower wheel doors, release tension on the blade, and move the blade guides away from the blade.

3.Put on heavy gloves, then slide the blade off the upper and lower wheels, around the blade post, and through the table slit.

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.

To correctly tension the blade:

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.
