Open the under floor drain valve then gently open the steam regulator.
When the lubricator has blown clean, close the regulator and remove the
lubricator cap. Now close the drain valve and refill with superheat steam
oil to the correct level. Re-fit the lubricator cap. All this time the engine
has had the fire alight and will have a good head of steam, so now carry
on running.
Keep an eye on the water level at all times and try to refill the gas tank
and lubricator every 20 minutes to half an hour.
End of Run
As previously mentioned, the locomotive will slow (due to pressure
dropping) when the fire has gone out, stop at a convenient place and
open the lubricator drain valve. Blow out all condensed water and the
remaining oil. Leave the drain valve open and allow the remaining steam
to blow out. The locomotive should be allowed to cool. When cool clean
the engine, check the motion and oil if necessary. The locomotive should
always be put away in a clean condition as it attracts less dust and is
always ready for the next run (or to be shown to an admiring friend).
Always leave the lubricator drain valve and the boiler blow down valve
open so that the boiler will not be strained if subject to any temperature
change. It is advisable to store the locomotive where any residual drips
of oil or water do not matter.
Blocked Gas Jets
If the gas jet becomes blocked with particles of dirt within the gas, the jet
will have to be removed and cleaned. With a spanner or pliers carefully
undo the pipe union on the gas control valve. Remove the pipe hand jet
holder assembly from the burner. Holding the jet gently in vice, unscrew
the jet. To clear, place the jet nozzle against the inverted gas can nozzle
and clear the jet with a blast of gas. Under no circumstances use a
pricker wire, this will damage the jet hole.
Replace the jet in the holder, ideally using a thread sealant sparingly on
the threads. Ensure it is tightened up firmly. Replace the assembly into
the burner and re-connect the pipe to the control valve. Ensure this is
done up tightly, test
CAREFULLY
for gas leaks, first with a 50/50 mixture
of washing up liquid and water, and then if no bubbles are showing, with
a flame and the gas “just on”. Tighten if required.
