General Hints
As with all operating machinery, whether model or full size, wear will
occur. In the model steam locomotive much can be done to help prolong its
life and decrease the amount of time required in the workshop for servicing.
Keep the engine as clean as possible, and the motion free from dirt and
garden debris. The valve gear, axles and crank pins should be oiled
sparingly with light oil, e.g. “3-in -1 Oil”. Over-oiling attracts dirt and grit,
which will increase wear.
Regularly check that all screws and motion bolts are firm. Do not over-
tighten, as this strips threads and shears bolts
. When filling the
lubricator, always use a high
temperature steam oil; this is available
from your dealer. FAILURE TO USE THE CORRECT GRADE OF
OIL CAN LEAD TO BLOCKED STEAM PIPES, AND WILL
INVALIDATE THE GUARANTEE.
When running your engine avoid excessive speed and acceleration, both
will cause premature wear in the valve gear. Prototypically, narrow gauge
locomotives ran at a speed of between 10 and 20 M.P.H., and never
exceeded 25 M.P.H.
Positions of Fillers and Drains etc.
The cab roof lifts up then tilts over sideways to give access to all fillers.
The gas inlet valve
is in the front near side corner of the cab, at the top of
the gas tank turret. The gas control valve is attached to the filler turret, and
can be operated through the left hand cab doorway.
The lubricator
is in the offside of the cab, by the doorway. The filler cap
has a “T” bar in it to aid removal. The lubricator drain is just in front of the
right hand cab step. To drain, un-screw the drain valve through about a turn
using the small brass tool with the steel pin handle, and hole in the end of
the brass part. Put the hole over the pin in the side of the drain valve and
turn.
