Belt Tracking
The belt tracking knob and lever (Figure 26) stops the
belt from tracking off of the drums and shutting down
the machine. Your goal is to position the belt tracking
lever so the belt tracks in the center of the drums and
theleft-and-rightbeltmovementtakesasimilaramount
of time.
Note: To fine-tune the left-and-right movement you will
adjust Belt Oscillation Speed outlined on Page 23.
To set the belt tracking, do these steps:
1. Complete the Jet Air FlowadjustmentonPage 21.
2. Putonsafetyglasses,tiebackallloose clothing,
