LeeBoy 6150 Conveyor Paver 4-27
Operation
6. 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 4-57)
NOTE: Never allow the endgate to carry the weight of
the screed to prevent uneven compaction.
7. If the endgate digs into the asphalt at the front,
adjust the tilt screw until the endgate tilts back more.
8. On the rst pass, leave approximately six to eight
inches (15 - 20 cm) of unrolled asphalt where the
joint will be made.
9. When making a joint, the endgate must be set to
where it ts ush with bottom of screed.
Figure 4-57. Endgate Tilt Screw Adjustment
NOTE: Keep runners clean. When making a joint,
spray solvent on the runners.
10. 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.
11. If making a cold joint, set the endgate down about
1/4 inch (6.35 mm) for a nice, even edge.
You can extend or retract the screed extension using
the extension switch on the main control panel. (Pages
3-6 to 3-11) A remote control box is also provided on
both sides of the main screed with switches to extend or
retract the screed, set the slope, open/close the cut-off
gates and turn the auger on and off while paving. (Fig-
ure 4-56) (If equipped with the optional sloping exten-
sions, an additional switch for this feature is also located
on the remote control box.)

Adjust the screed extension while paving using the fol-
lowing procedures:
1. Move paver to the starting position for paving.
2. Extend the screed to the desired width.
3. To set the depth, you can place small starter blocks
as shown in Figure 4-55.
4. Level the screed using the tow point.
• 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. Make minor adjustments if
needed.
5. 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 4-54)
