Safety Rules

WARNING

Generator produces powerful voltage.

Failure to properly ground generator can result in electrocution.

Failure to isolate generator from power utility can result in death or injury to electric utility workers due to backfeed of electrical energy.

•When using generator for backup power, notify utility company.

•DO NOT touch bare wires or receptacles.

•DO NOT use generator with electrical cords which are worn, frayed, bare or otherwise damaged.

•DO NOT handle generator or electrical cords while standing in water, while barefoot, or while hands or feet are wet.

•If you must work around a unit while it is operating, stand on an insulated dry surface to reduce shock hazard.

•DO NOT allow unqualified persons or children to operate or service generator.

•In case of an accident caused by electrical shock, immediately shut down the source of electrical power and contact the local authorities. Avoid direct contact with the victim.

•Before performing any maintenance on the generator, disconnect the battery cable indicated by a NEGATIVE, NEG or (-)first.When finished, reconnect that cable last.

•After your Home Generator System is installed, the generator may crank and start without warning any time there is a power failure.To prevent possible injury, push and hold the START/RUN/STOP switch in STOP position until generator stops and LED turns off, remove the service disconnect from the disconnect box AND remove the 15 Amp fuse BEFORE working on the equipment.

WARNING

Propane and Natural Gas are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•Install the fuel supply system according to applicable fuel-gas codes.

•Before placing the Home Generator System into service, the fuel system lines must be properly purged and leak tested.

•After the generator is installed, you should inspect the fuel system periodically.

•NO leakage is permitted.

•DO NOT operate engine if smell of fuel is present or other explosive conditions exist.

•DO NOT smoke around the generator.Wipe up any oil spills immediately. Ensure that no combustible materials are left in the generator compartment. Keep the area near the generator clean and free of debris.

CAUTION

Excessively high operating speeds increase risk of injury and damage to generator.

Excessively low speeds impose a heavy load.

•DO NOT tamper with governed speed. Generator supplies correct rated frequency and voltage when running at governed speed.

•DO NOT modify generator in any way.

CAUTION

Exceeding generators wattage/amperage capacity can damage generator and/or electrical devices connected to it.

•See “Essential Circuits”.

•Start generator and let engine stabilize before connecting electrical loads.

CAUTION

Improper treatment of generator can damage it and shorten its life.

•Use generator only for intended uses.

•If you have questions about intended use, ask dealer or contact Briggs and Stratton.

•Operate generator only on level surfaces.

•Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation.

•The access door and roof must be installed whenever the unit is running.

•DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.

•Despite the safe design of the Home Generator System, operating this equipment imprudently, neglecting its maintenance or being careless can cause possible injury or death.

•Remain alert at all times while working on this equipment. Never work on the equipment when you are physically or mentally fatigued.

•DO NOT start engine with air cleaner or air cleaner cover removed.

•DO NOT insert any objects through cooling slots.

•DO NOT use the generator or any of its parts as a step. Stepping on the unit can cause stress and break parts.This may result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, ect..

•If connected devices overheat, turn them off and disconnect them from generator.

•Shut off generator if:

-electrical output is lost;

-equipment sparks, smokes, or emits flames; -unit vibrates excessively.
