Unloading Mode
Follow these procedures when unloading excess
asphalt from the Maximizer 2B Review these
instructions and follow them to insure the safety of the
operator and to maintain a safe working environment
Be sure that the material in both
tanks is compatible (see Material Considerations in
Section 4) . If material is not compatible or if you are
not sure, do not transfer!
1 Check the temperature of the material in the tank
Be sure that it is hot enough to be transferred
without setting up in the transfer lines or the pump,
(see Material Considerations in Section 4)
NOTE: If the temperature is marginal or material is
starting to set up, fill the tank with fresh, hot
material to heat it Set the Mode Selection switch
to TANK CRCLT for 5 minutes to mix and heat the
remainder before unloading
Heat material before moving the unit
next to storage tanks . Some asphalt materials emit
flammable vapors that can be ignited by the burner
flame and cause an explosion.
It may be necessary to operate the
burners to heat the tank prior to unloading . In this
case, be sure that the fire tubes are covered with
at least 8 inches of material, (see Burners & Torch
Operation in Section 6) .
Do not operate burner equipment when
the vehicle is being loaded or unloaded. The flue
tubes could be exposed causing an explosion inside
the tank, or the material could ignite, causing a fire.

Do not open the Transfer Valve
until transfer line is in place . Failure to follow this
procedure could result in serious burns to the
operator from hot asphalt in the lines . The Transfer
Valve must be opened and closed manually .
Check the storage tank for
condensation . If necessary drain the storage tank
before unloading the Maximizer 2B .
