Engine Throttle should be set at full power. Signal
the driver to leave the truck in neutral with the-
dump body raised a sufficient height to allow
asphalt to flow slowly but continuously inth the
Hopper.
Laying The Asphalt
11. Position the Extension Control Levers to adjust the
desired paving width if it is to be more than 9 feet.
12. Move the Track Control Levers to the “forward”
position. Continue forward, laying asphalt and
pushing the truck approximately 36 to 48 inches. If
vibration is desired on the Screed, move the
Vibrator Control Lever to “on” position at approx-
imately the same time the Track Control Levers are
moved to the “forward” position.
13. Move the Track Control Levers to “neutral” posi-
tion, stopping the Paver. ALWAYS move the
Vibrator Control Lever to “off” position when
stopping forward motion of the Paver. It may be
necessary to signal the truck driver to stop, if the
truck is moving.
NOTE:
The truck should NOT be in gear nor
should the driver “ride” the brakes. Always advise
the truck driver of the procedure for pushing the
truck with the Paver.
14. Check thickness/depth of asphalt in the 36 to 48
inch mat and make necessaary adjustment using
the Manual Depth Adjustment Screws. Make
adjustments up or down gradually to avoid por-
poising effect or ripples in the mat as a result of
adjusting too much in either direction. If the base
on which the asphalt is being laid is on grade and
level, only infrequent adjustments will be required
after initial asphalt thickness/depth setting is made.
NOTE:
Refer to the Troubleshooting chapter in
this manual for Paver related, or material delivery
and compaction related paving mat application
problems.
15. Move the Track Control Levers to “forward” and
continue to pave until the truck is empty and the
Hopper is approximately 50% full.
NOTE:
Leave a small head of asphalt at the
leading edge of the Screed while waiting for the
next load of asphalt. If the wait is longer than 10
to 15 minutes, pave 12 to 18 inches further and
again leave a small head of asphalt. Repeat in 10
to 15 minute intervals using asphalt remaining in
the Hopper until next load arrives.
If the Paver is to be used independently of the dump
truck, disregard procedures involving pushing the
dump truck for continuous feed while paving (dis-
cussed in Steps 10-13) and refer to the following:
16. After the Hopper is fully loaded, signal the truck
driver to lower the dump body, stopping the flow
of asphalt to the Paver. Simultaneously, the Paver
Operator should move the Hopper Control Lever
to the “up” position raising the Hopper to avoid
asphalt spills from the front of the Hopper.
17. The Paver Operator should then signal the truck
driver to move forward to the next place to reload
the Paver. This next reloading place may be direct-
ly in front of the Paver at a point where the Paver
Operator expects the Hopper to be emptied, or
another location on the jobsite.
PRECAUTIONS WHILE PAVING
The right side Control Levers for Auger, Extension,
Track and Hopper modes allow a two-man operation to
avoid making “blind” joints and to reduce cycle time
when paving in two directions.
The Screed Vibrator should be operated ONLY when
the Paver is moving to avoid undue compaction in the
mat when the Paver is stopped.
Do NOT raise the Hopper against the truck frame or
the dump body of the truck.
When pushing a truck on level ground, the truck
should NOT be in gear and the truck brakes should
NOT be held. The Paver will NOT push a truck with
the brakes on.
The two independently operated Augers need ONLY
be used when the Extensions are out and then only “off
and on”. The Augers are used ONLY for keeping the
extended area fully charged with asphalt.
NOTE:
Do NOT leave the Augers operating con-
tiuously unless required!
If the Hopper is loaded and the Operator wishes to
close the Flow Gates to transport material to an area
inaccessible to the truck, or reposition the Paver for the
next pass, etc., the following procedure should be
employed. ALWAYS lower the Hopper as low as pos-
