Pennsylvania K-4 'Pacific'
OPERATION AND MAINTENANCE INSTRUCTIONS
The Kohs & Company Pennsylvania K-4 locomotive is an exact scale replica of the original pro-
totype. It is constructed of formed and fabricated brass and incorporates many scale operating
features. Although the model is very sturdily built, the boiler, tender shell and particularly 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 front pilot beam and the rear cab deck. When touching the painted surfaces,
it is advisable to wear the supplied gloves to protect the finish.
This locomotive model is designed to operate on Direct Current (DC) electricity. Any applica-
tion of Alternating Current (AC) WILL DESTROY THE INTERNAL ELECTRONIC COM-
PONENTS 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 specification
recommendations under the heading of 'Power Supply Requirements', please make note of the
information offered.
Before unpacking, handling or operating your new 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.
