TOOL KIT The following items are included with your locomotive. One small bottle of special steam oil for use in the lubricator. One 60ml syringe with plastic tube for filling the boiler with water. One spare gas jet. One set of spare washers and ‘0’ rings. One Allen key for cylinder socket cap screws.
A special brass gas filler adapter is obtainable from your local garden railway supplier or direct from ROUNDHOUSE. Mixed gasses are also available and may be used if ordinary butane or iso-butane are not available, but see ‘Gas System’ on page 13 for more information on this subject.
2) FILLING THE BOILER The boiler is filled with water through the safety valve bush, housed on top of the boiler under the dome nearest the cab. This painted brass dome is a substantial and heavy item, being turned from solid brass.
3) LUBRICATION Regular lubrication of all working parts is important and should be carried out before each operating session. There are two types of lubrication required: The external moving linkages and bearings are lubricated with a medium oil such as motor engine oil, and the internal steam mechanisms such as cylinders, pistons and valves are lubricated with a special steam oil that is mixed with the steam.
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.
troubleshooting. For the first couple of minutes keep the burner on low. This is important, as until it warms up, the flame will be a little unstable and turning it up too much could cause it to go out. Also, with a completely full tank, liquid gas could be drawn off instead of vaporised gas, which can also extinguish the flame.

amount of water in the pipes and cylinders which will cause the engine to run jerkily until it is exhausted through the chimney. This is known as priming and is quite normal and will clear after a few moments. If the engine appears to ‘lock up’ during initial starting from cold, it is often helpful to close the regulator and gently move the engine manually to expel the excess water from the cylinders then open the regulator just a little to allow a small amount of...
For those who would like longer runs, a set of parts is available from ROUNDHOUSE to add a water level gauge and water filling system. This allows the boiler to be topped up at any time and maintain a fairly constant water level.
TROUBLE SHOOTING & MAINTENANCE On a working model of this nature, it is important to keep all working parts well lubricated. With constant heating up, cooling down and the stresses of hard work, screws etc. can work loose particularly over the first few hours of running.
leak, a service kit is available which includes replacement gaskets and seals and full instructions for fitting. Steam leaking from the front or rear cylinder covers can be cured by carefully tightening the four screws that hold each one to the cylinder block. These covers are fitted with gaskets.

the temperature of the gas but should increase to its normal level as the engine warms up. This is quite normal) Carefully, disconnect the gas pipe from the gas jet holder using a 2BA spanner. Note when connecting or disconnecting the gas pipe and jet block, do not use excessive force.

Beneath the knob is a back-lash spring and white PTFE washer which will slide off the spindle. Unscrew the hexagon retaining nut then screw the spindle out of the body. The ‘O’ ring can now be lubricated. Replace the spindle followed by the retaining nut. Slide the white PTFE washer and backlash spring over the spindle and replace the knob.

Please refer to the ‘owner’s handbook’ for your particular model of locomotive, for details on correct use of these pressure vessels. Pressure vessel care and maintenance Gas tank The gas tank is used for the storage of LPG (liquefied petroleum gas) in the form of butane, iso-butane or as set out in the ‘owners handbook’.
