Circulating Product in the Bar
WARNING
To prevent an explosion or fire hazard: Ensure
that the burners are extinguished before
removing any material from the tank in any
manner. Liquid petroleum (LP) burners can
support a flame for several minutes after the
fuel supply is turned off.
1. Set all of the valve positions first.
Perform the procedure for circulating in the tank first.
Then move the rotary actuator knob to the “Circulate
in Bar” position. The circulate in bar procedure can be
performed from either the cab or the rear control panel.
CAUTION
To prevent excessive pressure in the spray bar,
the asphalt pump speed should not exceed
160 GPM while circulating in the spray bar.
Circulate product long enough to ensure removal of
all air from the bar and to heat the spray bar valves
sufficiently. For better material circulation, in the bar
ends, the wings should be extended.
Spraying Operations
A correct spray pattern cannot be obtained unless
the product is heated to its proper spraying tempera-
ture. Cold product will not provide sharp spray edges,
and will cause streaking. If heating of the product is
required, refer to the section of this manual on “Heat-
ing Product in Distributors” or your Operator’s Manual
for instruction on operation of your particular type of
burners.
The computer automatically adjusts the asphalt pump
speed to deliver the correct amount of asphalt for the
application rate, spray width and vehicle speed. The
circulation rate in the bar when not spraying should be
set to 50% of the pump speed while spraying. This cir-
culation rate will allow the asphalt pump to reach the
desired speed quickly when spraying is started. Circu-
lation rates higher than 50% will result in a heavier start
while rates below 50% will produce a lighter start.
WARNING
To prevent an explosion or fire hazard: Ensure
that the burners are extinguished before
removing any material from the tank in any
manner. Liquid petroleum (LP) burners can
support a flame for several minutes after the
fuel supply is turned off.
To prevent an explosion: Do not operate the
burners when the vehicle is unattended, when
the vehicle is in motion, or with the vehicle in a
confined area.
To prevent an explosion or fire hazard: When
the burners go out, shut off the fuel supply to
both burners and allow the flues to ventilate for
at least 3 minutes before re-lighting the
burners.
To prevent an explosion or fire hazard: Do not
heat the material beyond the manufacturer’s
recommended temperature.
To prevent an explosion or fire hazard: Keep
burning cigarettes or other sources of
combustion away from manholes and overflow
vents.
To prevent possible hand or facial burns:
Always light the inside burner first. Do not
reach across a lit burner to light or re-light the
inside burner. Shut off the outside burner
before lighting the inside burner.
To prevent possible burns from material
overflow: Allow sufficient space in the tank for
expansion of the material when heating
To prevent possible burns to operators or
bystanders, or possible equipment damage, do
not start any operation if any control settings
are unknown.
To prevent possible burns from leaking
material: Be sure all pipe, cap and hose
connections are secure before opening valves.
