WARNING
To prevent an explosion or fire hazard: Keep
burning cigarettes or other sources of
combustion away from manholes and overflow
vents.
10. Open the valve at the supply source and monitor
the tank gage. When the gage shows full, close the sup-
ply valve.
11. After closing off the supply valve, While the dis-
tributor pump is turning, carefully break the connec-
tion between the supply source valve and the hose until
you hear a vacuum and elevate the hose to allow maxi-
mum drainage to the fill line.
WARNING
To prevent burns: Always wear insulated
gloves when handling spray bar sections or
hoses.
12. Allow the pump to continue turning while the
hose is disconnected from the fill line and the fill line
cap is replaced and secured.
13. Reduce the pump rate to 0 using the circulation
rate switch.
Filling from the Rear Control Panel
1. Set all of the valve positions first.
2. Turn the “Power Switch” “on” at the cab control
panel.
3. At the rear control panel, turn the “Pump Con-
trol” knob fully counterclockwise to insure the pump
is at minimum speed before switching to the rear pump
control.
4. Place the “Pump Control” switch to the “rear” po-
sition to enable control of the pump from the rear.
5. Place the “Suction Valve” switch in the “Closed”
position to prevent sucking material out of the tank.
6. Turn the “Master Power” switch “On”.
7. Adjust the “Pump Control” knob to get the de-
sired 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 begun by using pump con-
trol knob. Depending on material viscosity, as the load-
ing rate is increased, the asphalt pump may cavitate.
When this happens, the pump will make a distinctive
sound, easily recognized with experience. Short peri-
ods of operation while the pump is cavitating will not
damage the pump but you should not operate the pump
in this condition for extended periods.
