TION
WARNING
To prevent an explosion or fire hazard: Keep
burning cigarettes or other sources of
combustion away from manholes and overflow
vents.
WARNING
To prevent burns: Always wear eye protection,
long sleeve shirt, insulated gloves, boots, and
long pants outside the boots when working
around the distributor.
Ensure that both the fill line and the suction strain-
ers are clean and properly installed.
Ensure that all connections between the distributor
and the supply source are tight to prevent asphalt leaks.
Air leaks will reduce the vacuum and slow down the
filling operation. The distributor is designed to suck
asphalt through the fill line. Do not pressurize the fill
line with an external pump.
WARNING
Before removing the fill line cap, make certain
that the asphalt pump is turning and the
suction valve is closed.
Filling from the Cab
If you have not yet done so, read “Filling through
the fill line” before continuing.
1. Set all of the valve positions first. (See Fig 2)
2. Be sure that the master power switch is in the off
position to insure that nothing can function while
switches are being set.
3. Turn the “Spray Bar” switch “off” to insure that
the spray bar valves remain closed when the “Master”
switch is turned back on..
4. The optional Front/Rear “Suction” switch can be
in either position.
5. Turn the “Rotary Actuator” knob to the “Load/
Suckback” position. This positions the 4-way valve in
the “Load” position.
At the rear panel:
Place the “Pump Control” switch in the “front” po-
sition. This disables the rear panel pump control and
makes the front panel pump control active.
Place the “Suction Valve” switch in the closed posi-
tion. This insures that the pump will not remove any

material from the tank.
Turn the “Master Power” switch “on” to enable the
front control panel.
6. At the cab panel, turn the “ Power” switch “on”.
Both the front and rear power switches must be on to
operate.
7. Set the digital display to “GAL/SQ. YD; FPM;
GPM” by using the “Change Display” button so you
can see the pumping rate displayed.
8. Run the engine at a minimum of 1100 RPM.
WARNING
To prevent possible burns from material
overflow: Allow sufficient space in the tank for
expansion of the material when heating
9. Toggle the “Circulation Rate” switch up or down
to obtain the desired rate. A pump rate of 75 GPM is
recommended to begin the loading operation. The pump
rate can be increased at any time after loading has be-
gun by using the circulation rate toggle switch. Depend-
ing on material viscosity, as the loading rate is increased,
the asphalt pump may cavitate. When this happens, the
pump will make a distinctive sound, easily recognized
with experience. Short periods of operation while the
pump is cavitating will not damage the pump but you
should not operate the pump in this condition for ex-
tended periods. Higher speeds will not load thick ma-
terial faster. Light materials or materials at spraying
temperature, may be loaded at faster pump speeds.
