5. if the vehicle steering is too responsive (remains on course but the

wheels oscillate quickly back and forth), adjust the oil flow DOWN slightly
in increments of 1/8 turn on the flow control valve. After each adjustment
of the oil flow, drive the vehicle and observe the behavior before making
additional adjustments.

6. if the vehicle steering is not responsive enough (drifts away from the

guideline or overshoots the guideline and does not correct quickly), ad-
just the oil flow UP slightly in increments of 1/8 turn on the flow control
valve. After each adjustment of the oil flow, drive the vehicle and observe
the behavior before making additional adjustments.

tighten the locking nut on the flow control valve.

oil flow position and tighten the locking nut on the flow control valve. Pro-
