Whilst I am not familiar with that particular Locomotive the following should be a help to get you started. I am assuming this to be a Gas Fired Locomotive.
First remember this routine acronym as it is the safest way to get your Locomotive ready WOG.
1 WATER Fill Boiler with water, best to use Water from a de-humidifier if you can as Tap Water can introduce limescale. Rain Water if filtered can be ok but must be very well filtered perhaps through a dedicated Water Filter. So called Ionised water can also be a problem as it is these days produced in a way that is not ideal for miniature pipework.
2 OIL Steam Oil in the receptacle, this lubricates the cylinders. Loco instructions should show where this is. You need a special thick Steam oil and if you have not had any supplied with the loco to start you off then these people can help.

3 GAS you may need an adapter to fill your locomotive with Gas, use Butane I get mine from Halfords. You can use Butane / Propane Mix but only outside in the Winter as Propane has a higher preasure than Butane when hot and in Summer that is not good.
4 Now that you have attended to the inner requirements of the locomotive an oil round the moving parts is in order, for this a small container of Car Engine Oil is appropriate, though you could use something like 3 in 1 but I prefer the slightly thicker mess of the car engine oil.
5 Turn on Gas and put a Match or Small Gas lighter where it says in the instructions to light up (generally over the top of the Chimney). Usually this will be followed by a Pop as the excess leaked gas ignites. First time can be a little scary but the pop is quite normal. Gas should be heard to roar a little, though if the burner is a ceramic one it wil not. Either way you should be able to feel heat from the Chimney to show the fire is alight. If the burner is roaring it can be adjusted some to reduce the roar.
6 Once you have achieved a blow off at probably 40psi then you can start up the engine. Be prepared to catch the beast if it storms off, control can be in cases a little hit and miss but experience will show you the way.
Good luck and have fun with your little dragon. Send us some pics when you have mastered the little beast enough to manage a Photo as well as running.
