1. Adjust the tracking knob (#23) so that upper
wheel is not angled.
2. Set a straightedge against the sides of the
wheels. It should fully extend across both of
them.
Figure 5.
3. The straightedge must touch each of the out-
side rims on both wheels. If the straightedge
does not touch both wheels evenly, use a
small ruler to measure the distance that the
lower or upper wheel is offset from the long
straightedge.
If the straightedge already touches the wheels
evenly, move on to the tracking procedures.

Co-Planarity 2. Add washers behind the upper or lower
wheels as needed.
3. Remove washers behind the UPPER
WHEEL ONLY.
4. Adjust parallelism (i.e., if the middle of the
wheels are co-planar, but the sides are not).

5. Loosen the four cap screws (#10) that
secure the two sliding gibs (#9) to the body
behind the upper wheel.
Figure 7 .
6. Adjust the setscrews (#11) in or out very
slightly (over adjustment will cause the ten-
sion rod to bind) to make the upper wheel
parallel with the lower wheel.
7. Tighten the four cap screws and check
wheel co-planarity.
8. Repeat 1- 4 for further adjustment if needed.
The distance you measured with the small ruler
is the distance that the wheels must be corrected.
The following steps allow you to align the wheels.
If one step works, immediately proceed to the
tracking adjustment instructions.
1. Turn the tracking knob to adjust the angle of
the upper wheel.
