a. Check the parking brake is set and the asphalt tank gauge reads
above the fire line.
b. Open exhaust stack.
c. Start burners as needed.
d. Monitor temperature to circulate as soon as possible.
e. Follow instructions for warm asphalt circulation above.
CAUTION: TO AVOID EQUIPMENT DAMAGE, HEAT THE MATERIAL
SLOWLY IF MOISTURE IS PRESENT IN THE TANK. THE
MATERIAL TEMPERATURE WILL NOT RISE ABOVE
212°F UNTIL THE MOISTURE IS GONE.
Do not circulate material in the spray bar at first. As much as 20%
of the heat developed in the asphalt can be dissipated due to heat
losses in the spray bar.
