Holding the loco by the front and rear footplates, roll it off onto the track, lining up the wheels as they exit the cradle base. Because the loco wheels sit in cut-outs in the base, it is necessary to lift the model very slightly... -

full. Remove the canister immediately. Filling times will vary depending on the temperature of the locomotive and are for guidance only. 2) FILLING THE BOILER There are two methods of filling the boiler 1/ Quick filling when cold. The brass dome in the centre of the boiler can be lifted off to allow access to the safety valve. - Page 9 making filter to remove any particles or debris in the water. Do not use deionised water as this 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 30 ml of water with the syringe.

maintaining this downward pressure. Keep pumping until the water level in the water gauge is almost at the top of the glass. Remove the plastic tube. Note that a small amount of water will remain in the top of the valve but will evaporate away as the valve heats up. 3) LUBRICATION Regular lubrication of all working parts is important and should be carried out before each operating session. -

steam pressure should be raised in about 4 minutes with a cold boiler. If, after 5 or 6 minutes, pressure is not rising, shut off the gas and re-light. If this still does not improve matters, see the section on the gas system in the Troubleshooting. -

damage will result if the gas is turned off immediately and the engine left to cool naturally. Never add cold water to a hot, empty boiler in an attempt to cool it and never re-fill the gas tank without first checking the water level in the boiler. -
Page 14: Water Top-Up System
NOTE: Ensure that the valve gear is fully in gear for the required direction when the engine is moving. The model is fitted with a simplified Walschaerts type valve gear which is not suitable for 'notching up' (altering the cut off). Always bring the locomotive to a halt by closing the regulator before changing direction. - Page 15 glass as you pump so allow the level to settle after a few pumps. Carefully pull the plastic pipe out of the water top up valve whilst steadying the engine. Sometimes, small particles of dirt will find their way in with the water and may cause the water filling valve to leak back a little when the pipe is removed.

Page 16: Troubleshooting & Maintenance
TROUBLESHOOTING & MAINTENANCE On a working model of this nature, it is important to keep all working parts well lubricated as detailed in the lubrication section. With constant heating up, cooling down and the stresses of hard work, screws etc. can work loose so, it is good practice to check all fixings and cylinder screws regularly, particularly when the model is new but, remember - never over tighten. -

kit is available which includes replacement gaskets and seals and full instructions for fitting. WATER TOP-UP SYSTEM Over a period of time the end of the plastic filling tube that pushes in the boiler top-up valve will become a loose fit due to the heat of the fitting. To cure this, simply cut approximately 6mm from the end of the tube when necessary. -

gasses, i.e. Butane with a proportion of Propane mixed in. The mixed gas come in a variety of mixes ranging from 90/10 to 60/40 with one of the most common being 70/30. The figures refer to the proportions of the mix i.e. -

Note when connecting or disconnecting the gas pipe or gas jet holder, do not use excessive force. Wash out the jet in fast evaporating thinner (Cellulose or similar). Blow through the jet from the front, which should clear most blockages. Although the hole through the jet is tiny, if you hold it up to the light you should be able to see quite clearly if it is blocked or not. -
