To adjust the momentary wheels, stop the lane machine after it has traveled onto the lane approximately 2-3 feet past the foul line. Loosen the two bolts that hold the bracket to the lane machine and raise or lower the bracket assembly until you reach a gap of 1/16" to 1/8" (1.6mm to 3.2mm).
In some instances, you may need to raise the wheel a little higher to clean the front part of the lane closer to the foul line.
