Figure 7. Adjustments for tension and tracking.
Belt Tension
Belt tension is controlled by a spring loaded cam shaft. Push the Belt Tensioning Lever (part C, Figure 8) rearward to slacken the belt.
Belt Tracking
Plug in the machine. Test the belt tracking by turning on the unit and quickly turning it off. Note the lateral movement of the belt. If the belt does not move off the rollers, the belt is tracking cor- rectly. If the belt did move left or right off the rollers, tracking adjustment is necessary.
1.Loosen the Locknut (part A, Figure 8).
2.Use the 4mm Allen® wrench to turn the tracking adjustment bolt (part B, Figure 8). If the belt moves to the left, turn the adjust- ing bolt counterclockwise. If it moves to the right, turn the bolt clockwise.
3.With the machine running, adjust the track- ing so the belt stays on the middle of the wheel.
4.Turn off the machine.
5.While holding the adjusting bolt in the prop- er position, tighten the locknut without changing the adjustment.
Belt Platen
The belt platen should be adjusted so the belt just touches it. Loosen the two hex bolts and position the platen so it barely touches the belt. Tighten the two hex bolts securely. See Figure 8. If the platen is adjusted too far forward, it could adversely affect the belt tracking.
