6. Turn the end gate tilt screw so the front of the
endgate tilts down slightly when the screed is lifted.
This will allow the end gate to set itself to the grade.
(Figure 4-71)
• If the end gate digs into the asphalt at the front,
adjust the tilt screw until the endgate tilts back
more.

7. On the rst pass, leave approximately six to eight
inches of unrolled asphalt where the joint will be
made.
8. When making a joint, the end gate 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.
• 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.
Starting to Pave
The LeeBoy 8608 paver provides superior paving for
driveways, small to large parking lots, and secondary
roads. It has a production rate of approximately 250
tons per hour. This paver is capable of placing a mat
thickness of six inches (20 centimeters) for:
• Bituminous base.
• Binder or surface course.
• Lime or Portland cement-stabilized sub-base.
• Graded aggregate materials.
Operators should be trained to operate the various
machine components along with proper paving tech-
niques before paving.
Keep these items in mind:
• Plan the project so you pave the most narrow
passes rst (the width of the paver), leaving the
widest passes until last.
• Always pave in low gear.
• It is the operator’s job to guide the material truck
back to the hopper and signal the driver when to
stop dumping asphalt into the hopper. The driver
must maintain a light pressure on the brakes to
prevent the truck from dumping asphalt onto the
ground.
NOTE: If paver is equipped with the optional truck
hitch, the truck driver won’t need to maintain
brake pressure. (Page 4-41)
• Adjust the oscillating push rollers to the appropriate
height needed for asphalt trucks. (Figure 4-72) If
equipped with the optional truck hitch refer to Page
4-41 for operational instructions.
• There are ve (5) set heights on the truck push
rollers. A scraper behind each one scrapes
asphalt from the push rollers as you pave to
help prevent asphalt build-up.
