doing. You should develop a habitual scan that starts with:
• Looking for wires.
• Check the height of the dump bed.
• Check rear hopper level.
• Are the belts full and running intermittently.
• Front hopper mirrors for material level.
• Outside mirror for chip seal coverage.
• Back to the meet line.
Staring down at the edge or meet line can be hard on your neck and
forces bigger head movements during your scan. Learn to look out over
the front of the chipper at your line with a downward look now then
to check your accuracy. Looking forward improves your ability to drive
straight. Sitting forward leaning over the steering wheel causes you have
to make big body movements to preform your scan. This can make it
hard to drive straight. Sit back in your seat with both feet forward, get
comfortable and you will drive a straighter line.
Visibility can also include seeing the spray bar of the asphalt distributor.
Changes in width if visible can give you a heads up. Spotting plugged
nozzles can save a lot of patchwork. If you can see the spray bar and
spray pattern you are generally far enough back to not get covered in
asphalt over spray at the end of the day.
Application Rate
The Computer monitors the ground speed and controls the gate opening
to deliver the right application rate. In the preparation section we
calibrated the chipper prior to chipping. This set the display number to
read the actual output of the chipper. Most jobs have a target design
application rate and some fine tuning may be required after the initial
calibration. In the initial calibration we calibrated to within about 3
pounds of the desired rate and left it at that. Calibrating with a tarp on
the side of the road is a crude and moderately accurate process that
gets you close so you can fine tune later.
