ENGINE SAFETY

Internal combustion engines present special hazards during operation and fueling! Failure to follow the
safety guidelines described below could result in severe injury or death. Read and follow all safety
warnings described in the Engine Operator's Manual. A copy of this manual was supplied with the unit
when it was shipped from the factory.
• DO NOT run the engine indoors or in an area with poor ventilation unless exhaust hoses are used.
Diesel engine exhaust contains carbon monoxide, a deadly, odorless and colorless gas which, if
inhaled, can cause nausea, fainting or death. Make sure engine exhaust cannot seep into closed
rooms or ventilation equipment.
• DO NOT fill fuel tank near an open flame, while smoking, or while engine is running. DO NOT fill
tank in an enclosed area with poor ventilation.
• DO NOT operate with the fuel tank cap loose or missing.
• DO NOT touch or lean against hot exhaust pipes or engine cylinders.
• DO NOT clean air filter with gasoline or other types of low flash point solvents.
• DO NOT remove engine coolant cap while the engine is hot.
• DO NOT operate the unit without a functional exhaust system. Prolonged exposure to sound levels
in excess of 85dB(A) can cause permanent hearing loss. Wear hearing protection when working
around a running engine.
• Keep hands, feet and loose clothing away from moving parts on the generator and engine.
• Keep area around exhaust pipes and air ducts free of debris to reduce the chance of an accidental
fire.
• Batteries contain sulfuric acid which can cause severe injury or death. Sulfuric acid can cause eye
damage, burn flesh or eat holes in clothing. Protective eye wear and clothing are necessary when
working on or around the battery. Always disconnect the NEGATIVE (-) battery cable from the
corresponding terminal before performing any service on the engine or other components.

ELECTRICAL SAFETY

The unit is powered by a generator driven by a diesel engine. While the engine is running, potentially
lethal voltages are present at the 120V Ground Fault Circuit Interrupt (GFCI) outlets and the 240V twist
lock outlets located on the control panel, and at the connection lugs and cam lock receptacles. Failure
to follow the safety guidelines described below could result in severe injury or death.
• Only a qualified and licensed electrician should make connections to the generator.
• NEVER wash the unit with any high pressure hoses or power washers.
• NEVER start the unit under load. The circuit breakers must be in the "OFF" position when starting
the unit in MANUAL mode. The circuit breakers can be in the "ON" position only when started in the
AUTO mode. A transfer switch must be used in the AUTO mode to deflect the load upon start up.
• ALWAYS disconnect the NEGATIVE (-) battery cable from the corresponding terminal before
performing any service on the engine, generator or any other components. Remove the NEGATIVE
(-) battery cable from the corresponding terminal if the unit is to be stored or transported.
• ALWAYS use extreme caution when servicing this unit in damp conditions. Do not service the unit if
your skin or clothing is wet. Do not allow water to collect around the base of the unit.
• ALWAYS connect the unit to a good earthen ground before use. Follow any local, state, or United
States National Electric Code (NEC) guidelines.
