Note: For generator sets with an ADC 2100
controller and with serial numbers below
2051416: These units used an earlier version of
the ADC 2100 controller that was equipped with a
removeable power mode jumper at P7.
Operation of the remote digital gauge’s start/stop
function requires that the jumper is enabled on
the Advanced Digital Control (ADC) (generator
sets shipped from the factory already have the
jumper enabled). Refer to the wiring diagram in
the generator set operation manual if the jumper
was disconnected from terminals 1 and 2 on the
P7 connector (continuous power mode).
Note: For generator sets with an ADC 2100
controller: ADC application program version
3.32 or higher is required for complete digital
gauge operation. If your application program
version is lower than 3.32, use your SecurID to
access Kohler Power Resource Center, click on
the TechTools button, and follow the instructions
to download the files.
Note: For generator sets with a Decision-Makerr
3500 controller: Firmware version 1.14.3 or
higher is required for complete digital gauge
operation. If your firmware version is lower than
1.14.3, visit the Kohler Power Resource Center
website using the TechTools button.

Carbon monoxide.
Can cause severe nausea,
fainting, or death.
The exhaust system must be
leakproof and routinely inspected.
WARNING
Carbon monoxide symptoms. Carbon monoxide can
cause severe nausea, fainting, or death. Carbon monoxide
is a poisonous gas present in exhaust gases. Carbon
monoxide is an odorless, colorless, tasteless, nonirritating gas
that can cause death if inhaled for even a short time. Carbon
monoxide poisoning symptoms include but are not limited to
the following:
DLight-headedness, dizziness
DPhysical fatigue, weakness in
joints and muscles
DSleepiness, mental fatigue,
inability to concentrate
or speak clearly, blurred vision
DStomachache, vomiting, nausea
If experiencing any of these symptoms and carbon monoxide
poisoning is possible, seek fresh air immediately and remain
active. Do not sit, lie down, or fall asleep. Alert others to the
possibility of carbon monoxide poisoning. Seek medical
attention if the condition of affected persons does not improve
within minutes of breathing fresh air.
Operating the generator set. Carbon monoxide can cause
severe nausea, fainting, or death. Be especially careful if
operating the generator set when moored or anchored under
calm conditions because gases may accumulate. If operating
the generator set dockside, moor the craft so that the exhaust
discharges on the lee side (the side sheltered from the wind).
Always be aware of others, making sure your exhaust is
directed away from other boats and buildings.
Explosion.
Gasoline vapors can cause
explosion and severe injury or
death.
Before starting the generator set,
operate the blower 4 minutes and
check the engine compartment for
gasoline vapors.
WARNING
Ignition-protected equipment. Explosive fuel vapors can
cause severe injury or death. Gasoline vapors can cause an
explosion. USCG Regulation 33CFR183 requires that all
electrical devices (ship-to-shore transfer switch, remote start
panel, etc.) must be ignition protected when used in a gasoline
and gaseous-fueled environment.
