6. Continue with adjustments until the blade is  
tracking properly.  
7. Tighten the wing nut (E, Fig. 19) after blade  
is tracking in the center of the wheel.  
As you become familiar with the saw, you  
may find it necessary to change the blade  
tension from the initial setting. Changes in  
blade width, and the type of material being  
cut will have an effect on blade tension.  
Keep in mind that too little, or too much  
blade tension can cause blade breakage  
and/or poor cutting performance.
