PREPARING THE LOCOMOTIVE FOR OPERATION
Although your GG-1 is ready to operate, a few 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, while this will suffice for initial operation and break-in, you may wish to further lubricate areas
where moving parts are in contact with 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 was shipped to you with a scale 'tite-lock' style coupler installed for display purposes. For
operating and pulling consists you may replace the display coupler with 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 attempt to use
AC power as damage will occur
. The following criteria should be used when selecting your power
supply:
1) Direct Current (DC) which 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 power supply or one which does not meet the above criteria,
undesirable operating characteristics may result as well 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 which digitally recreates actual locomotive sounds
including air-horn, bell, blowers, brake release and pantograph air release. While this sound unit requires
track voltage to actuate certain sounds, the actual power used to operate the sound system is supplied by
two 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 pull on the wires
.
NOTE: If you do not plan to use your locomotive for an extended period of time it is highly
recommended that you remove these batteries and store them separately as with age they may
leak and cause substantial damage to the model.
The supplied sound system controller needs to be wired in-line between your power supply and the track in
order to control the internal sound system. There are four (4) screw terminals at the front of the box and
they are labeled in two 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 (-) with the 'A'
indicating (+) and the 'U' indicating (-). The power for the controller is supplied by the included 9V wall
adapter which simply plugs into the round receptacle on the front of the box, that being the side facing away
from you while reading the face plate. (refer to figure #2)
OPERATING THE LOCOMOTIVE
The minimum radius for operation is 70" with well 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 will help the drive system to 'run-in' resulting in smoother
running characteristics.
You are now ready to put the locomotive into operation. To activate the sound system, locate the sound
system switch under the center roof hatch it is labeled 'sound', slide it to the on position making certain the
'panto' switch is in the 'rail' position to take power from the rail or in the 'panto' position to take power from
an overhead cantenary system. With the locomotive stationary you will not hear any sounds until they are
manually activated or track power is applied. When track power is applied you will hear the brake release
sound and once the locomotive starts to move you will hear the blowers turn on. When the locomotive is
stopped, the blowers will automatically turn off.

The manual sound control functions are as follows:
1) 'Bell' one touch on and one touch off
2) 'Horn' sounds the horn when ever the button is depressed
3) 'Front Pan' raises the front pantograph while depressed
4) 'Front Pan' & 'Alt' lowers the front pantograph while depressed
5) 'Rear Pan' raises the rear pantograph while depressed
6) 'Rear Pan' & 'Alt' lowers the rear pantograph while depressed
7) 'Blowers' & 'Alt' manually controls the blower sound
8) 'Sound' & 'Alt' allows you to remotely turn the sound off while operating
9) 'Aux 1' no function currently
10) 'Aux 2' no function currently
