OPERATION
Filling the Hopper
1. Have the dump truck back up to the front of the
paver until the truck tires are one to two inches
(25-50 mm) from the push rollers.
2. Move the paver forward until the push rollers
contact the rear tires of the truck. Do not raise
the screed.
3. Move the hopper control lever to the "up" posi-
tion and hold it in this position until the hopper
almost touches the dump body of the truck.
4. Have the dump truck driver slowly raise the
dump body so that asphalt flows from the
dump body into the hopper.
IMPORTANT:
Be prepared to lower the
hopper to prevent the dump body from
striking the hopper.
5. Fill the hopper with asphalt.
6. Move the flow gate control levers to the "open"
position and hold them in this position until the
flow gates are completely open. Asphalt will
then gravity feed and form a head of asphalt at
the leading edge of the screed.
If the area to be paved is level and pushing the
truck is desired, move the hydraulic pump
speed control lever forward approximately 1/3.
The engine throttle should be set at full power.
If using the paver by itself, without a dump
truck, skip step 7 in “Filling the Hopper.”
7. Have the dump truck driver leave the truck
in neutral with the dump body raised to a
sufficient height to allow asphalt to flow
slowly but continuously into the hopper.
IMPORTANT:
Do not lift the hopper if
pushing a dump truck with the paver.
Damage to the paver/truck may result.
Laying the Asphalt
1. If the paving width is wider than eight feet.
(2438 mm), adjust the paving width by using
the extension control levers.
2. Move the speed/travel control levers to the for-
ward position. Adjust the speed control levers
to obtain the desired travel speed. Lay asphalt/
push the truck approximately 36 to 48 inches
(900 -1200 mm).
3. Make the screed vibrate by moving the
vibrator control lever to the "on" position while
moving the speed control lever "forward" to
the desired travel speed.
4. Move the speed control lever to the "neutral"
position to stop the paver.
Move the vibrator control lever to the "off"
position when stopping forward motion of the
paver. If a truck is being pushed and is moving,
have the dump truck driver stop.
NOTE:
When pushing a truck, the dump
truck should not be in gear and the dump truck
driver should not "ride" the brakes. Tell the
dump truck driver about the procedure for
pushing the truck with the paver.
5. Check the thickness/depth of asphalt in the 36
to 48 inch (900-1200 mm) mat and make any
necessary adjustments using the manual depth
adjustment screws.
Slowly make adjustments up or down to avoid
porpoising effect or ripples in the mat because
of adjusting too much in either direction.
If the base that the asphalt is being laid on is
graded and level, only make infrequent adjust-
ments after setting the asphalt thickness/depth.
NOTE:
See “Troubleshooting” on page 65
for paver-related and/or material delivery and
compaction-related paving mat application
problems.
6. Move the speed control lever "forward" and
continue to pave until the truck is empty and/or
the hopper is approximately 50% full.
