Blade Tensioner
The blade tensioner may need to be reset for one of the following reasons:
•The blade tension quick release lever will not move down into the horizontal position when the tension scale is correctly adjusted for the installed blade.
•You have installed a blade of a different length.

To reset the blade tensioner: |
|
1.DISCONNECT BANDSAW FROM POWER!
2.Move the blade tension lever up to the verti- cal position to release blade tension, then loosen the set screws on both spacers shown in Figure 68.
3.Rotate the spacers fully away from the cross- bar, then rotate the blade tension knob so that the red marker is at the blade width mark for the installed blade.
4.Pull the quick release lever down to the hori- zontal position.
5.Pull up on the tension knob to apply as much tension on the blade as possible.
6.While maintaining the upward pressure on the tension knob, thread the upper spacer down until it touches the crossbar, then re- tighten the set screw to secure it in place.
7.Thread the lower spacer down until it touches the top of the tensioner casting, then thread it back up
8.Move the quick release lever up to the vertical position and make sure there is no tension on the blade. If all the tension is not released, the lower spacer needs to be threaded farther down the shaft toward the tensioner casting.
