Priming The Smoke Unit; Checking The Battery - Lionel Tinplate 392 Steam Locomotive Operator's Manual

Priming the Smoke Unit

When preparing to run this engine, add 15-20 drops of smoke fluid through the
smokestack (see below). We recommend M.T.H. ProtoSmoke. Do not overfill the
unit or the fluid may leak out and coat the interior engine components.
Add Smoke Fluid
If you choose not to add the fluid (or have already added the fluid but choose to
run smoke-free), turn off the smoke unit off by turning the smoke volume control
to the minimum setting (counterclockwise). The smoke volume control is located
underneath the engine (see below). Failure either to add fluid to the unit or to
turn it off may damage the smoke unit heating element and/or wicking
material.

Checking the Battery

You may find, if your locomotive was built several months before you set it up, that
the rechargeable battery has run down and needs to be charged before operating.
If you notice that the sounds are garbled, test and charge the engine as described in
the "Self-Charging Battery Back-Up" on page 14.
