PREPARING FOR OPERATION
The locomotive must be serviced before being operated. It is
important to perform all the following operations.
1) FILLING THE GAS TANK
The filling of the gas tank should only be carried out in a well-
ventilated area, where there are no naked lights or other lighted
locomotives close by. Ordinary Butane or Iso-butane gas (as used
in gas cigarette lighters) is the preferred fuel, though for economy,
the larger canisters as used for blowlamps or camping stoves etc.
are better. The larger canisters have an EN417 threaded self
sealing valve on top and require a special adapter to couple up to
the filler valve on the locomotive. 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.
Before attempting to fill the gas tank, make sure that the gas
control valve is closed by turning it clockwise.
The filler valve for the gas tank is on top of the tank under the cab
roof. Invert the gas canister and place its nozzle over the gas filler
valve. Support the tank from underneath and press the canister
down. The gas will be heard hissing as it enters the tank and a
small amount will escape around the valve. This is quite normal
and is the tank venting as the liquid enters.
After about 20 to 30 seconds, liquid gas will emerge from the valve
showing that the tank is full. Remove the canister immediately.
