Continuous Running
Running for longer periods of time than the normal, requires the use of the Boiler
Filling System. This consists of a pump bottle with tube attached and a replacement
boiler filler cap, which has a non-return valve on its underside. For the first fill
service in the normal way. Then run for about 10 minutes, now have a look at the
water level. You will probably need to pump some water into the boiler. Lift up and
tilt over the cab roof to uncover the filler cap, place the tube in the hole and holding it
in firmly, pump water into the boiler until the gauge glass is showing about ¾ full.
Keep an eye on the water gauge and try to run between ⅓ and ¾ of a glass.
After another 10 minutes running you will need to refill the lubricator and top up the
gas tank. Also check the water level and top up if necessary. Stop the loco in a
convenient location, away from other locomotives and turn off the gas. Ensure the
fire is completely out and then top up the gas tank. Blow around the engine so there is
no residual gas about, then re-light the fire. To re-fill the lubricator, follow the
instructions at the beginning of page 3. Keep an eye on the water level at all times
and try to refill the gas tank and lubricator every 20 minutes to half an hour.
Gauge Changing
All ‘Lew’ locomotives are supplied set to 45mm gauge, but a “gauge change” kit is
supplied with each engine. This will allow you to run on either 32mm or 45mm
gauge track. To change the gauge, lay the engine gently on its side, on a thick cloth,
loosen all the grub screws in the boss on the back of the wheels using the Allen key
provided. The axles are dimpled for each gauge, so you do not have to measure for
the right gauge. Slide the wheels to the gauge required and tighten up the grub
screws. These should be checked as a routine at the start of each running session.
To change the pony trucks to 32mm gauge another set of wheels is supplied. With the
nut runner supplied, undo the two hexagon bolts holding the rectangular axle carrier
to the flat pony truck arm. Remove the complete wheel set assembly and replace with
the desired set. Ensure the hexagon bolts are replaced firmly, but do not over tighten,
you might strip the threads.
End of Run
The locomotive should be allowed to cool and all boiler pressure to go down. When
cool, gently release the water filler cap by about 2 turns to allow the boiler to have
free breathing space and not to create a vacuum as it cools. Now clean the engine,
check the motion and oil if necessary. The locomotive should always be put away in
a clean condition as it attracts less dust and is always ready for the next run (or to be
shown to an admiring friend). Always leave the lubricator and boiler filler caps loose
and the main steam valve open so that the boiler will not be strained if subject to any
temperature change. It is advisable to store the locomotive where any residual drips
of oil or water do not matter.
