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 the ‘Gas System’...
LUBRICATION Regular lubrication of all working parts is important and should be carried out before each operating session. The slip eccentric valve gear is located between the rear wheels and the frames and is lubricated by running oil down the back of the wheels. 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...
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.
that it is adequately filtered Do not use deionised water as this type of water may cause long term damage to the boiler and fittings. There has to be a space above the water to allow steam to be raised so, insert the end of the plastic pipe into the boiler and withdraw 30ml of water with the syringe.
safety valve will start to blow off steam, this can take up to 10 or 12 minutes in outdoor locations. Steam generation can be controlled by the gas valve in the cab. If the safety valve blows off frequently during running, then too much steam is being produced, which wastes water and gas.

will ensure the quickest results. Once the parts have warmed up, the engine will move off steadily and its speed can be controlled with the regulator. Subsequent starts will be quite smooth once the cylinders etc. have reached their normal operating temperature and the water level in the boiler has dropped a little.
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. The gas tank will still require refilling each time it is empty.
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. It is good practice to check all fixings and cylinder screws regularly but remember, never over tighten.
any leaks. Replace the main body over the boiler and exhaust pipes. With the front footplate central on the chassis, spring out the bottom of the side tanks a little and slide it back a little so that two tabs in the bottom of the cab sit just in front of the slots on the rear footplate.

and blue flames can be seen around the top of the fire box. It should be set so that there is a gap on both sides of 2 to 2.5 mm between the boiler and the top edge of the flap. Secondly, the tiny jet in these units can become blocked by small particles of dirt making the burner difficult to light, burn weakly at normal operating temperatures*, burn in the top of the firebox or fail...

The gas regulator has a spindle ‘O’ ring housed inside the body which may need lubrication from time to time if the control becomes ‘spongy’ in operation, making precise gas control difficult. As stated in the lighting instructions, the full range of adjustment (closed to fully open) is achieved within the first half to three quarters of a turn of the gas regulator knob, and it should only be unscrewed more than this for maintenance purposes and when the tank is...

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’.
