SAFETY PRECAUTIONS
Thoroughly read the OPERATOR’S MANUAL
before operating the genset. Safe operation and
top performance can only be obtained when
equipment is operated and maintained proper-
ly.
The following symbols in this manual alert you to
potential hazards to the operator, service person
and equipment.
DANGER
alerts you to an immediate hazard
that will result in severe personal injury or
death.
WARNING
alerts you to a hazard or unsafe
practice that can result in severe personal inju-
ry or death.
CAUTION
alerts you to a hazard or unsafe
practice that can result in personal injury or
equipment damage.
Electricity, fuel, exhaust, moving parts and batter-
ies present hazards which can result in severe per-
sonal injury or death.
GENERAL PRECAUTIONS
• Keep children away from the genset.
• Do not use evaporative starting fluids. They
are highly explosive.
• Do not step on the genset when entering or
leaving the generator room. Parts can bend or
break leading to electrical shorts or to fuel,
coolant or exhaust leaks.
• To prevent accidental or remote starting while
working on the genset, disconnect the nega-
tive ( – ) battery cable at the battery.
• Let the engine cool down before removing the
coolant pressure cap or opening the coolant
drain. Hot coolant under pressure can spray
and cause severe burns.
• Keep the genset, drip pan and compartment
clean. Oily rags can catch fire. Gear stowed in
the compartment can restrict cooling.
• Make sure all fasteners are secure and proper-
ly torqued.
•
Do not work on the genset when mentally or
physically fatigued or after having consumed
alcohol or drugs.
• You must be trained and experienced to make
adjustments while the genset is running—hot,
moving or electrically live parts can cause se-
vere personal injury or death.
• Used engine oil has been identified by some
U. S. state and federal agencies as causing
cancer or reproductive toxicity. Do not ingest,
inhale, or contact used oil or its vapors.
• Ethylene glycol, used as engine antifreeze, is
toxic to humans and animals. Clean up spills
and dispose of used engine coolant in accor-
dance with local environmental regulations.
• Keep multi-class ABC fire extinguishers
handy. Class A fires involve ordinary combus-
tible materials such as wood and cloth; Class B
fires, combustible and flammable liquid fuels
and gaseous fuels; Class C fires, live electrical
equipment. (ref. NFPA No. 10)
• Genset installation and operation must comply
with all applicable local, state and federal
codes and regulations.
GENERATOR VOLTAGE IS DEADLY
• Generator electrical output connections must
be made by a trained and experienced electri-
cian in accordance with applicable codes.
• The genset must not be connected to shore
power or to any other source of electrical pow-
er. Back-feed to shore power can cause elec-
tric shock resulting in severe personal injury or
death and damage to equipment. An approved
switching device must be used to prevent inter-
connections.
•
Use caution when working on live electrical
equipment. Remove jewelry, make sure cloth-
ing and shoes are dry, stand on a dry wooden
platform or rubber insulating mat and use tools
with insulated handles.
ENGINE EXHAUST IS DEADLY
•
Never sleep in the boat while the genset is run-
ning unless the boat is equipped with properly
working carbon monoxide detectors.
