caution when using a torch to heat the pump.
Asphalt accumulated around the pump may
ignite when heating the pump with a torch
If the product is too cold to be circulated, some
heating with the burners will be needed to
increase the temperature enough to be able to
start circulating. Refer to the portion of this
operating manual for instructions on your
particular type of burner.
WARNING
To prevent an explosion or fire hazard: When
the burners go out, shut off the fuel supply to
both burners and allow the flues to ventilate for
at least 3 minutes before re-lighting the burners
WARNING
To prevent an explosion: Do not operate the
burners when the vehicle is unattended, when
the vehicle is in motion, or with the vehicle in a
confined area
