New York Central J3a 'Hudson'
OPERATION AND MAINTENANCE INSTRUCTIONS
The Kohs & Company New York Central J3a 'Hudson' locomotive is an exact scale replica of the
original prototype. It is constructed of formed and fabricated brass and incorporates many scale
operational features. Although the model is very sturdily built, the boiler, tender shell and par-
ticularly the detailing are very susceptible to damage by rough or careless handling. To prevent
damage, please exercise great care in unpacking and handling the model. The locomotive is best
handled by lifting under the pilot 'horns' and rear cab deck. When touching the painted
surfaces be advised to wear the supplied gloves to protect the finish.
This locomotive model is designed to operate on Direct Current (DC) electricity. Any application
of Alternating Current (AC) WILL DESTROY THE INTERNAL ELECTRONIC COMPO-
NENTS OF THIS MODEL. Kohs & Company will not be responsible for damage caused by the
application of AC power to the model. We will offer further power supply specifications under
the heading of 'Power Supply Requirements', please make note of these recommendations.
Before unpacking, handling or operating this model PLEASE TAKE THE TIME TO FULLY
READ THIS MANUAL. This is a small investment in time to protect your substantial financial
investment and to prevent unnecessary disappointment and frustration.

The locomotive has been lightly lubricated during assem- bly and testing, while this will suffice for initial operation and break-in, you may wish to further lubricate the side rod assemblies by applying 1 or 2 drops of good quality fine oil to areas where moving parts are in contact with each other (refer to figure #1).

If you have questions regarding your selection, do not hesitate to contact us for advise. PREPARING THE SOUND SYSTEM FOR OPERATION The locomotive and tender contain a state-of-the-art sound system which digitally recreates actual locomo- tive sounds including steam whistle, bell, blowers, compressors, emergency relief valve and cylinder ex-...

Your 'Hudson' is also equipped with an electronic control for the re- verse-gear mechanism. The system responds to the polarity of the power reaching the model and not the movement of the model.
