The adjustments on the Model G0659 allow the upper and lower wheels to be tilted relative to each other to reach coplanarity.

To adjust the wheel coplanarity:

1.Detension the blade.

2.Behind the upper wheel, loosen the cap screws indicated in Figure 56. Only slightly loosen the upper two cap screws. This mini- mizes lateral movement of the upper wheel and ensures accurate adjustments.

3.Through the lower wheel, loosen the three hex nuts indicated in Figure 57. Only slightly loosen the upper two hex nuts. This again minimizes lateral movement of the lower wheel and ensures accurate adjustments.

4.Locate the set screws indicated in Figures 5657. Adjusting these set screws changes the angle of the wheels.

5.Properly tension the blade (Page 26).

6.Again use your coplanarity gauge to check the tilt of the upper and lower wheels. If pos- sible, have an assistant hold the gauge while you make adjustments to the set screws. Adjust as necessary until the gauge touches the top and bottom of both wheels, as shown in Figure 58.

Note: The two set screws on the lower wheel assembly must be adjusted in equal incre- ments to ensure proper wheel alignment.
