TM 5-3895-374-10ItemProcedure1Connect the two heat transfer lines and the asphalt transfer line from the asphalt tanker to the dedrummer.See section 2-5.2Open the valves on either side of these lines allowing the heat transfer fluid to circulate through thededrummer. The asphalt transfer line will be open and will permit pumping of asphalt cement from thededrummer to the asphalt tanker.3Raise jib and install electric hoist on to the trolley. See section 2-5.4Position the hydraulic power pack beside the goose neck of the trailer on the left hand side and connect thehoses to the control valve for the drum feed cylinder.5Plug the power cable for the electric hoist and the power cable for the hydraulic power pack into the controlvan.6Unlatch the two doors at the discharge (rear) end of the dedrummer tank.NoteThe hot oil heater on the asphalt tanker must be running. Use a temperature set point of 3500 onthe heat transfer controller mounted on the hot oil heater. This higher temperature will maintainthe heat transfer fluid at a higher temperature and will compensate for the heat required to raisethe temperature of the asphalt cement In the drums. Allow the temperature of the dedrummer torise to at least 250° prior to feeding drums into the unit This temperature Is checked on the dialthermometer mounted on the front wall of the dedrummer tank.7Use the chain hoist and the drum rotator to lift the drums up to the platform or use a forklift to raise the drumsto platform height.8‘Remove the lid from the drum.NOTEItem number 8 may be performed prior to lifting to the platform.9Using the hoist, lift the drum six to eight inches and with the drum rotator turn the drum upside down.10Using the jib and the chain hoist, position and lower the drum into the drum feed system.11Open the doors to the dedrummer.12Start the hydraulic power pack motor by turning the breaker switch mounted on the pack to the ON position.page 2-119
