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 so, it is good practice to check all
fixings and cylinder screws regularly but remember, never over tighten.
STEAM LEAKS
The cylinders are fitted with 'O' rings in the glands sealing both piston and
valve rods. These can be adjusted with a spanner if steam leaks develop. They
should only be tightened just enough to stop the leak, as over tightening will
affect the running of the model. Cylinder covers are fitted with gaskets and
valve chests with 'O' rings . A little 'bubbling' of oil may sometimes occur
around these and is quite normal, however, steam leaking past the gasket
should be attended to. If 'nipping up' retaining screws does not stop a steam
leak, a service kit is available which includes replacement gaskets and seals
and full instructions for fitting. Valve chest screws on top of the cylinders are
accessed by removal of the dummy cylinder cover which simply clips round
the cylinder. Spring it gently out from the bottom and lift off the valve chest at
the top.
REGULATOR NOT SHUTTING (R/C models)
The steam regulator seating and seal can, after a period of time become worn
or compressed so that when the lever on the radio control is fully closed, the
locomotive still moves. To overcome this, a trimmer is fitted to the
transmitter. This is the small lever at the side of the main control lever and is
set at the factory to the top of its slot. As wear takes place in the regulator, it
can slowly be moved down the slot to compensate. When it reaches the
bottom, it is time to reset it to the top and adjust the linkage between the servo
and the regulator in the cab. If adjustment does not cure this problem, the
internal '0' ring may be damaged and requires replacement. Contact the
factory for further advice. Periodic oiling of the gland will help keep the
regulator working freely. Place a spot of motor oil between the gland nut and
the regulator arm and work the regulator a few times.
RADIO CONTROL
I
f the radio control gives problems, always check the batteries first and
replace
if in doubt. AA size batteries are used, four in the tender and eight in
the transmitter. If problems occur whilst running the locomotive near other
r/c engines, check that yours is on a different frequency.
