Retract the extenders. You will need a 1220 mm (48 inch) straight edge. Use the height control to raise the extender above the main screed plate. Place the straight edge (4) on the outside edge of the main screed plate.
Use the height control to lower the extender until the trailing edge of the extender (1) touches the straight edge (4).
Move the straight edge to the opposite end of the extender. Use the slope control to adjust the extender until the trailing edge of the extender (1) touches the straight edge. The trailing edge of the extender should be parallel to the main screed plate.
Measure the gap (A) between the leading edge of the extender and the straight edge (4). The correct dimension for the gap is 3.175 mm (0.125 inch).

If dimension (A) is not correct, use the extender leveling adjusters to obtain the correct gap. Increase gap (A) by lowering the trailing edge of the extender. Decrease gap (A) by raising the trailing edge of the extender.
After adjusting the trailing edge of the screed plate, use the height control to raise the extender. Repeat steps 1 through 5. If the gap is now correct for the retracted extender proceed to step 7.
Place the straight edge along the outside edge of the main screed and extend the extender. Observe gap (A) as you extend the extender. If the gap varies, there could be a twist in the carriage extender tubes.

Relieve the twist in the carriage extender tubes by loosening the end bolts (5) and (6). This will allow the extender to relax. Tighten the bolts for the upper carriage extender tube (5) in a cross pattern. Tighten the bolts for the lower carriage extender tube (6) in a cross pattern. Repeat steps 1 through 7.
