Troubleshooting
Applying Material
Problem | Cause | Solution | |
|
|
| |
|
|
| |
Ragged line edges when extruding | Dirty screed box | CAREFULLY clean box. Discharge | |
|
| opening and die plate runners need | |
|
| to be free of debris. | |
|
|
| |
| Cold material temperatures | Heat material as required. | |
|
|
| |
| Marking speed too fast | Slow Thermolazer™ speed. | |
| Material thickness too think | Slow Thermolazer™ speed and keep | |
|
| screed box filled. | |
|
|
| |
Rough material surface when extrud- | Overheated material | Reduce heat. | |
ing |
|
| |
Moisture on road surface | Allow road surface moisture to dry. | ||
| |||
|
|
| |
| Rough road surface | Smooth road surface. | |
|
|
| |
| Screed box low on material | Add material to screed box. | |
|
|
| |
EXAMPLES: |
|
|
Correct line application will produce a full straight line with sharp edges; correct color, thickness and width; a firm bond to the surface; and have uniform reflectivity.
