To adjust the support bearings:

1.Loosen the lock bolt approximately 1⁄4 turn. Note—If you loosen the lock bolt too much, the support bearing will fall out of place.

2.Turn the adjustment shaft until the support bearing is positioned approximately 0.016" behind the back of the blade. Use a feeler gauge or four thicknesses of a dollar bill to check this.

3.Tighten the lock bolt, and repeat with the other support bearing.

4.Test the adjustment of the support bearings by spinning the wheels by hand, at full blade tension, in the same direction of operation. While you are spinning the wheels, the sup- port bearings should not turn. (The support bearings should only turn during cutting operations.)
