Illustration 7 g03714827
Use thickness screw adjustment handle (8) to set the face to face measurement to 480 mm (19 inch). Note: Screeds equipped with the tamper option use knob (9) to set the face to face measurement.
Tighten locknut (7).
Verify that there is zero crown in the main screed.
Illustration 8 g03645001
Place Tool (A) across the width of main screed plate (10) approximately 25.4 mm (1 inch) behind the leading edge.
Place two of Tool (B) between Tool (A) and the screed plate. Locate each Tool (B) approximately 25.4 mm (1 inch) from the ends of main screed plate (10).
Illustration 9 g03669446
Use a third Tool (B) as a gauge in order to check the gap between the screed plate and Tool (A). This check should be taken at the center of main screed plate (10).
Illustration 10 g03645091
Use crown increase switch (12) and crown decrease switch (11) to adjust the crown. The space between Tool (A) and Tool (B) should be equal at all three locations.
Illustration 11 g03645030
Place Tool (A) across the width of main screed (10) approximately 25.4 mm (1 inch) in front of the trailing edge.
Place two of Tool (B) between Tool (A) and the screed plate. Locate each Tool (B) below the first adjuster at each end of main screed plate (10).
Illustration 12 g03720805
Use a third Tool (B) as a gauge in order to check the gap between the main screed plate and Tool (A). This check should be taken below each adjuster. Check from the outer edges of the main screed plate to the center of main screed plate (10).
If the trailing edge of the screed plate is flat and straight, go to Step 11. If the trailing edge of the main screed plate is not flat and straight, go to "Adjustment Procedure", "Trailing Edge Adjustment".
Remove tooling. Adjustment Procedure
Trailing Edge Adjustment
Illustration 13 g03719454
Use extender proportional extender switch (13) to extend the right and left extenders.
Illustration 14 g03713713
Remove two bolts (15) and washers. Remove plate (14).
Illustration 15 g03670108
Retract the inner trailing edge adjusters (17) and outer trailing edge adjusters (16).
Use inner trailing edge adjusters (17) to set the flatness of the trailing edge. Do not disturb outer trailing edge adjusters (16). Start at the second trailing edge adjuster in from each side and move to the center.
Illustration 16 g03669955
Loosen nut (18) on top of inner trailing edge adjusters (17) only. Turn the trailing edge adjuster counter-clockwise to retract the adjuster. Turn the trailing edge adjuster clockwise to extend the adjuster. Flatten the trailing edge of the main screed plate relative to Tool (A).
Tighten nut (18).
Remove tooling.
Position plate (14) and secure with two bolts (15) and washers. Reset the Scales
Illustration 17 g03671629
Loosen bolts (20) and move indicator (21) to the zero mark on thickness scale (19). Tighten the bolts.
Illustration 18 g03695774
Loosen bolts (24) and move crown scale (23) so the zero mark aligns with pointer (22).
