Using the hydraulic control valve mounted on the left hand side of the platform, extend the drum feed cylinder
pushing the drum into the tank. (One or two drums may be pushed in at one time).
The drum will not go all the way into the tank. Proceed with the next one or two drums and place
them in the drum feed system. Extend the hydraulic cylinder and the first two drums will be
pushed all the way into the tank and the second one or two will protrude slightly.
Continue this process as long as required.
At one to two hour intervals, transfer the liquid asphalt from the dedrummer tank to the asphalt tanker by
running the asphalt transfer pump mounted on the front of the asphalt tanker. Open the valve to the asphalt
tank and select the asphalt pump switch to the ON position. Run the pump for as long a period as required to
empty the dedrummer tank.
Select OFF on the asphalt pump switch and close the valve to the asphalt tank.
The empty drums will exit the doors at the rear of the tank.
If the drums are not empty of asphalt when they exit the dedrummer tank, they are not
hot enough. Correct this by increasing the set point temperature of the hot oil heater
(caution: do not exceed 4000) or increase the time that the drums are in the tank.
Upon completion of the dedrumming operations, pump all asphalt cement from the dedrummer tank, close the
four valves to the hot oil lines connecting the dedrummer and the asphalt tanker. Allow the dedrummer to cool
before attempting to remove the last of the empty drums from the tank.
On the hydraulic power pack, select the breaker to the OFF position.
