Operation
3. Level the screed using the electric ight screw
gauge (Figure 4-45).
• Refer to the elevation gauge (one on each side
of the paver for your convenience). Raise or
lower until the rod end of the cable is ush with
“0” on the gauge.
• While paving, refer to both gauges and make
minor adjustments if needed.
4. On the rst pass, turn the endgate depth screw to
lower the endgate until it is about 1/4-inch below the
screed. (Figure 4-55)

5. 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 4-56)
• If the endgate digs into the asphalt at the front,
adjust the tilt screw until the endgate tilts back
more.
• When making a hot joint, the endgate must be
set to where it ts ush with bottom of screed.
NOTE: Never allow the endgate to carry the weight of
the screed to prevent uneven compaction.

6. On the rst pass, leave approximately six to eight
inches of unrolled asphalt where the joint will be
made.
7. 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.
8. 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 of travel to correct itself.
NOTE: Too much adjustment up or down may cause
uneven pavement.
9. If making a cold joint, set the endgate down about
1/4 inch for a nice, even edge.
