© 2000 by Kohs & Company, Inc - Clarkston, Michigan 48348
The Kohs & Company Pennsylvania Railroad GG-1 locomotive is an exact scale replica of the
original prototype. It is constr cted of formed and fabricated brass and incorporates many scale
operational feat res. Altho gh the model is very st rdily b ilt, the body shell, pantographs and
partic larly the detailing are very s sceptible to damage by ro gh or careless handling. To
prevent damage, please exercise great care in npacking and handling the model. The locomo-
tive is best handled by lifting nder the main frames on both sides at the center of the model,
when to ching the painted s rfaces, be advised to wear the s pplied gloves to protect the finish.
This locomotive model is designed to operate on Direct C rrent (DC) electricity. Any application
of Alternating C rrent (AC) WILL DESTROY THE INTERNAL ELECTRONIC COMPO-
NENTS OF THIS MODEL. Kohs & Company will not be responsible for damage ca sed by the
application of AC power to the model. We will offer f rther power s pply specifications nder
the heading of 'Power S pply Req irements', please make note of these recommendations.
Before npacking, handling or operating this model PLEASE TAKE THE TIME TO FULLY
READ THIS MANUAL. This is a small investment of time to protect yo r s bstantial financial
investment and to prevent nnecessary disappointment and fr stration.
LOCOMOTIVE CARE AND MAINTENANCE
Routine maintenance consists of periodic lubrication as described under the heading 'Preparing For Opera-
tion' and replacement of the sound system batteries covered under the heading 'Sound System'. It is advis-
able to periodically check the tightness of the small fasteners used to assemble the detailing to make certain
that parts ill not be lost. If the model ill not be operated for an extended period of time, remove the
batteries from the locomotive .

PREPARING THE LOCOMOTIVE FOR OPERATION
Although your GG-1 is ready to operate, a fe preventive maintenance steps should be taken to ensure the
smooth operation and longevity of the model. The locomotive has been lubricated during assembly and
testing, hile this ill suffice for initial operation and break-in, you may ish to further lubricate areas
here moving parts are in contact ith each other by applying 1 or 2 drops of good quality fine oil. Your
local hobby dealer should be able to guide you in the selection of a suitable lubricant.
The locomotive as shipped to you ith a scale 'tite-lock' style coupler installed for display purposes. For
operating and pulling consists you may replace the display coupler ith the Kadee unit of your choice, the
holes are predrilled and tapped for the installation.
POWER SUPPLY REQUIREMENTS
The Kohs & Company 'Hudson' is a Direct Current (DC) electric scale locomotive. Do not attem t to use
AC ower as damage will occur. The follo ing criteria should be used hen selecting your po er
supply: 1) Direct Current (DC) hich is filtered
2) 0-18 volts (DC)
3) Minimum available current should be approximately 8.0 amps
Should you choose to use a less expensive po er supply or one hich does not meet the above criteria,
undesirable operating characteristics may result as ell as possible damage to the electronics used in the
model. If you have questions regarding your selection, do not hesitate to contact us for advise.
PREPARING THE SOUND SYSTEM FOR OPERATION
The locomotive contains a state-of-the-art sound system hich digitally recreates actual locomotive sounds
including air-horn, bell, blo ers, brake release and pantograph air release. While this sound unit requires
track voltage to actuate certain sounds, the actual po er used to operate the sound system is supplied by
t o standard 9 volt batteries that are placed in the center section of the cab (refer to figure #1) during the
operation of the locomotive,. When you disconnect the batteries, do not ull on the wires.
NOTE: If you do not lan to use your locomotive for an extended eriod of time it is highly
recommended that you remove these batteries and store them se arately as with age they may
leak and cause substantial damage to the model.
The supplied sound system controller needs to be ired in-line bet een your po er supply and the track in
order to control the internal sound system. There are four (4) scre terminals at the front of the box and
they are labeled in t o pairs, 'from trans' and 'to track', these should be pretty self-explanatory. Each
terminal is further labeled either 'A' or 'U', these are the international markings for (+) and (-) ith the 'A'
indicating (+) and the 'U' indicating (-). The po er for the controller is supplied by the included 9V all
adapter hich simply plugs into the round receptacle on the front of the box, that being the side facing a ay
from you hile reading the face plate. (refer to figure #2)
OPERATING THE LOCOMOTIVE
The minimum radius for operation is 70" ith ell laid consistant rail alignment, turnouts need to be #6 or
larger. It is recommended that you operate the locomotive at a varying speeds and in both directions during
the break-in period, the break-in period should last for a total of approximately 60 minutes (this may be
accomplished on an incremental basis). This ill help the drive system to 'run-in' resulting in smoother
running characteristics.
You are no ready to put the locomotive into operation. To activate the sound system, locate the sound
system s itch under the center roof hatch it is labeled 'sound', slide it to the on position making certain the
'panto' s itch is in the 'rail' position to take po er from the rail or in the 'panto' position to take po er from
an overhead cantenary system. With the locomotive stationary you ill not hear any sounds until they are
manually activated or track po er is applied. When track po er is applied you ill hear the brake release
sound and once the locomotive starts to move you ill hear the blo ers turn on. When the locomotive is
stopped, the blo ers ill automatically turn off.

The manual sound control functions are as follo s:
1) 'Bell' one touch on and one touch off
2) 'Horn' sounds the horn hen ever the button is depressed
3) 'Front Pan' raises the front pantograph hile depressed
4) 'Front Pan' & 'Alt' lo ers the front pantograph hile depressed
5) 'Rear Pan' raises the rear pantograph hile depressed
6) 'Rear Pan' & 'Alt' lo ers the rear pantograph hile depressed
7) 'Blo ers' & 'Alt' manually controls the blo er sound
8) 'Sound' & 'Alt' allo s you to remotely turn the sound off hile operating
