Figure 4-22. Lower Guide Bar Gauge
Avoid low limbs, power lines, and
other objects that can endanger crew or paver.
Components operate in both automatic and manual
mode.
The paver can operate using one side only. Material
from the opposite side cannot be augered to the
working side. It is possible to leave both cut-off gates
shut and open the endgates on the screed for paving
potholes and patching.
Basic Paving
1. Follow the start-up procedure. (Page 4-4)
2. Position paver at the starting point for the mat.
3. Adjust screed as needed. (Page 4-12)
4. Open cut-off gates under auger. (Page 4-15)
5. Open hopper wings. (Page 4-14)
NOTE: Allow only a partial load of asphalt to enter
the hopper when rst starting to pave.
6. Turn the left and right conveyor sonic paddle
switches to the PADDLE position and set speed
using the right and left conveyor dials. The conveyor
speed can be adjusted while paving if needed.
NOTE: When in the AUTO mode, the conveyors will
operate at the selected speed but will turn on
and off when using the sonic auger. (Page
4-15)
7. Turn the left and right auger switches AUTO, using
the dials to control the pile height at the endgate.
(Page 3-6)
8. When the material starts moving into the sonic
range, the auger speed will slow proportionately
and turn off, then turn back on when the material
level drops.
NOTE: The pile height must be set to the highest
point when the endgates are closed. When
the endgates are open, the pile height will
lower to prevent material from pushing in
front of the endgates.
9. When the material begins to discharge from under
the screed, set the screed lift switch to the FLOAT
position. (Page 3-6)
10. Begin paving, moving slowly at rst to adjust the
screed if needed.
11. Make a paving pass until the asphalt level in the
hopper is low.
Never back up with cut-off gates open.
NOTE: To prevent excessive handwork, set the left
and right conveyor sonic paddle switches
to the OFF position and set both cut-off
switches to the CLOSE position about three
feet from the end of the pull to prevent
excessive handwork.
12. Return paver back to starting position to begin the
next pull.
13. Position and set the screed endgate on the joint
side back to “0” feet, or ush with bottom of the
screed.
14. Repeat these steps as you continue to pave.
