6. On the rst pass, turn the endgate depth screw to
lower the endgate until it is about 1/4-inch (6.35 mm)
below the screed. (Figure 4-14)

7. Turn the tilt screw so the front of the endgate tilts
down slightly when the screed is lifted. This will allow
the endgate to set itself to the grade. (Figure 4-15)
NOTE: Never allow the endgate to carry the weight
of the screed to prevent uneven compaction.
Figure 4-15. Endgate Tilt Screw Adjustment
8. If the endgate digs into the asphalt at the front,
adjust the tilt screw until the endgate tilts back more.
9. When making a joint, the endgate must be set to
where it ts ush with bottom of screed.
10. On the rst pass, leave approximately six to eight
inches (15 - 20 cm) of unrolled asphalt where the
joint will be made.
11. When making a joint, the endgate must be set to
where it ts ush with bottom of screed.
NOTE: Keep runners clean. When making a joint,
spray solvent on the runners.
12. If the joint looks too high or too low, adjust the ight
screw on the screed one turn at a time and allow
four to ve feet (1.2 - 1.4 m) of travel to correct itself.
NOTE: Too much adjustment up or down may cause
uneven pavement.
13. If making a cold joint, set the endgate down about
1/4 inch (6.35 mm) for a nice, even edge.
