WARNING
To prevent burns: Always wear insulated
gloves when handling spray bar sections or
hoses.
11. Allow the pump to continue turning while the
hose is disconnected from the fill line and the fill line
cap is replaced and tightened.
Filling through the Manhole
Be sure that the suction valve switch is in the closed
position before starting to fill the distributor through
the manhole.
Set all of the valve positions first.
To reduce the risk of accidental discharge of asphalt,
the asphalt pump should not be running when filling
through the manhole. When the gage shows full, close
the supply valve
WARNING
To prevent possible injury: Always open the
manhole cover slowly. Pressure build up in the
tank may cause the cover to burst open.

WARNING
To prevent possible burns from material
overflow: Allow sufficient space in the tank for
expansion of the material when heating
Higher pump speeds will not load thicker materials
faster. Lighter materials, or heavy materials which are
already at spraying temperature, may be loaded at faster
rates.
WARNING
To prevent an explosion or fire hazard: Keep
burning cigarettes or other sources of
combustion away from manholes and overflow
vents.
8. Open the valve at the supply source and monitor
the tank gauge. When the gauge shows full, Close the
supply valve
9. After closing the supply tank valve, while the as-
phalt pump is still turning, carefully break the con-
nection between the supply source valve and the hose
until you hear a vacuum and elevate the hose to al-
low maximum drainage to the fill line.
10. Disconnect the hose at the supply end and el-
evate the hose to allow maximum drainage of the prod-
uct into the fill line.
