Spraying emulsion
Spraying a specific amount of emulsion on the pavement surface is the
purpose of the spray paver. When Spray Auto is selected, the emulsion
pump will turn slightly to pre‐pressurize the spray bar system, so that
immediate application occurs when the master power switch on the
pendent control is selected.
The schematic in the Appendix (page 126) shows the pump group valving
when the display screen unit is set to Spray Auto.
Using the spray bars
Note:
See page 31 for adjusting the spray nozzles.
1.
Use the Sprayer Selection screen to extend the telescoping spray
bars to the screed width, tilt the front spray bar down, and select
spray nozzles.
2.
Select
Pump Function
>
Spray Auto
, and activate the pump, and
set the application rate
3.
Turn on the master spray switch on the pendant control to start
spraying.
4.
When the paver stops, the “Turn off the master switch!” will
appear. Turn off the master spray switch to prevent the emulsion
from draining through the nozzles.
Tip:
Starts and stops during spraying occur many times on a
job site. If another spray application is not going to be started
within a few minutes, select Pump function>Spray Bar Circulate.
This prevents emulsion from cooling down and clogging the
piping.
