The Under Auger Material Cut-Offs are another
important function of the paver. (Figure 4-60) The cut-
offs are used primarily to control the ow of asphalt to
the screed and hydraulic screed extensions. Cut-offs
can limit material ow when making narrow passes at
the beginning and ending of each pass or pull. Proper
use of the cut-offs minimizes clean-up at the end of
pulls.
NEVER back up with the cut-offs open.
• Use the right and left cut-off switches on the control
panel open and close the cut-offs. (Figure 4-61)
• Pushing the switch to the OPEN positions
increases asphalt ow to the screed. Pushing the
switch to the CLOSED position decreases asphalt
ow to the screed.

The tow point is an added convenience to the operator
for making minor adjustments to mat thickness while
paving. A screed height gauge is located on both sides
of the paver to provide the operator with a quick refer-
ence to the location of the tow point. (Figure 4-62)

1. Before paving, refer to the tow point gauge (located
on both sides of the operator platform).
2. Raise or lower the screed until the cable rod end is
ush with “0”on the decal.
3. Set the Grade/Slope switch to SLOPE on both sides
of the main control panel. (Figure 4-63)

4. Slowly move both joysticks forward.
5. Use the Thicker/Thinner switch on both sides of the
control panel to adjust mat thickness as you pave.
6. While paving, refer to both gauges to make minor
screed adjustments using the tow point.
