drain screw and refill the lubricator from the top with the steasm oil
supplied. Replace the cap. Take time filling the lubricator,
especially when cold, as the oil takes time to run down and may
trap an air bubble. Both cap and drain screw are fitted with ‘0’ rings
and need only be closed finger tight.
NOTE:
Only special steam oil as supplied should be used in the
lubricator and under no circumstances should ordinary oil be
substituted, or damage may result. The gas and steam regulators
will require periodic lubrication – see the troubleshooting section for
details.
4) LIGHTING THE BURNER
WARNING:
Before lighting read the section on gas system
troubleshooting and be aware of potential problems. If the gas
system is not operating correctly,
shut it off immediately
or
damage may result.
After filling the gas tank, move the locomotive to another location
before lighting. Butane is heavier than air and small pockets of gas
can collect around the locomotive during filling. To light the burner,
hold a lighted match or cigarette lighter over the top of the chimney
and
slowly
open the gas regulator by turning it anti-clockwise. The
gas should ignite almost immediately with a pop as the flame
travels down the chimney and into the boiler tube. The burner
should be audible but not too loud.
NOTE
as stated above, the gas regulator should be opened slowly
until the burner ignites. If opened too quickly, particularly when the
engine is cold or if the gas tank has just been filled, it is possible
that the flame may not travel back into the boiler flue but stay in the
smokebox. If this should happen, the burner will sound quite
different to normal and the blue flame will be visible in the
smokebox if viewed down the chimney from a safe height. Should
this happen, turn off the gas immediately or damage may result,
and then re-light it. If the problem persists, and it is not possible to
ignite the burner correctly, then refer to gas system
