Turn blade tracking knob (E, Figure 8) clockwise to   

track blade toward front of blade wheel.

Turn tracking knob counterclockwise to track blade    

toward rear of blade wheel. Blade should be tracked  

as close to center of top blade wheel as possible.

away and left loose from the blade while tracking ad-
justments are being made.
