Troubleshooting
40 3A1320L
Swollen rounded line • Material temperature is too high • Lower material temperature.
Material shadows on sides • Uneven road surface
• Screed box is not evenly riding on
substrate
• Apply to even road surfaces.
• Remove debris from screed box
lever rod.
• Inspect/replace damaged screed
box lever rod/lever arm.
Line is wavy • Strong road surface camber
• Incorrect ThermoLazer operation
• Apply so camber does not influ-
ence application.
• Use correct application methods
(for example, try locking swivel
wheel).
Cracks in line • Cracks in road surface
• Temperature stress from
overheating
• Material applied too cold
• Material applied too thin
• Repair cracks.
• Lower temperature in material.
• Increase material temperature.
• Slow ThermoLazer speed to apply
thicker material.
Rough edges and lines in surface • Material temperature is too low
• Material is overheated or scorched
• Moisture in road surface
• Raise material temperature.
• Lower material temperature.
• Wait until road surface is dry.
Jagged line ends; material drips
between lines
• Screed box does not fully close
• Debris caught in screed box
• Worn screed box shear bar
• Worn screed box trough shear bar
stop
• Surface temperature too cold
• Clean screed box.
• Clear debris from screed box.
• Replace screed box gate.
• Replace screed box trough.
• Allow surface temperature to
increase.
