Although both wheels can be adjusted to accom- plish correct wheel alignment, we recommend that you start with the upper wheel, and, if necessary, continue the adjustments with the lower wheel.
When both wheels are correctly aligned with one another,
The upper wheel adjusting fasteners consist of four locking hex bolts and four adjusting hex bolts with jam nuts (see Figure 47).

To adjust the upper wheel:
1.Loosen the upper wheel locking hex bolts, then loosen the jam nuts (see Figure 47).
2.Use the adjustment hex bolts to bring the upper wheel coplanar with the lower wheel.
Note: Threading an adjustment hex bolt in will force that part of the wheel forward. Conversely, threading an adjustment hex bolt out will pull that wheel section to the rear of the machine when the locking hex bolt is re- tightened.

The lower wheel adjustment assemblies have a locking hex bolt threaded into an adjustment sleeve (see Figure 48).

To adjust the lower wheel:
1.Loosen the locking hex bolts of the lower wheel.
2.Loosen or tighten the adjustment sleeves as necessary to bring the lower wheel coplanar with the upper wheel.
Example 1: If the top of the lower wheel leans too far forward (see fourth example in Figure 49), thread the top two adjustment sleeves out.
Example 2: Alternately, if the lower wheel is parallel to the upper wheel but behind the plane of the upper wheel (see second example in Figure 49), then thread all four adjustment sleeves in.
