GENERAL SAFETY RULES

Never use the inverter in a location that is wet or damp. Never expose the inverter to rain, snow,
water spray or standing water while in use. Protect the inverter from all hazardous weather conditions.
Moisture or ice can cause a short circuit or other malfunction in the electrical circuit.

Never operate the inverter in an enclosed area. Engine exhaust contains carbon monoxide. Only
operate the inverter outside and away from windows, doors and vents.

Voltage produced by the inverter could result in death or serious injury.

• Never operate the inverter in rain or a ood plain unless proper precautions are taken to avoid being
subject to rain or a ood.

• Never use worn or damaged extension cords.

• Always have a licensed electrician connect the inverter to the utility circuit.

• Never touch an operating inverter if the inverter is wet or if you have wet hands.

• Never operate the inverter in highly conductive areas such as around metal decking or steel works.

WARNING

WARNING

Gasoline and gasoline vapors are extremely ammable and explosive under certain conditions.

• Always refuel the inverter outdoors, in a well-ventilated area.

• Never remove the fuel cap with the engine running.

• Never refuel the inverter while the engine is running. Always turn engine o and allow the inverter to

cool before refueling.

• Only ll fuel tank with gasoline.

• Keep sparks, open ames or other form of ignition (such as match, cigarette, static electric source)

away when refueling.

• Never overll the fuel tank. Leave room for fuel to expand. Overlling the fuel tank can result in a
sudden overow of gasoline and result in spilled gasoline coming in contact with HOT surfaces.
Spilled fuel can ignite. If fuel is spilled on the inverter, wipe up any spills immediately. Dispose of rag
properly. Allow area of spilled fuel to dry before operating the inverter.

• Wear eye protection while refueling.

• Never use gasoline as a cleaning agent.

• Store any containers containing gasoline in a well-ventilated area, away from any combustibles or

source of ignition.

• Check for fuel leaks after refueling. Never operate the engine if a fuel leak is discovered.

WARNING

Never operate the inverter if powered items overheat, electrical
output drops, there is sparking, ames or smoke coming from the
inverter, or if the receptacles are damaged.

Never use the inverter to power medical support equipment.

Always remove any tools or other service equipment used during
maintenance from the inverter before operating.

Never modify the inverter.

Never operate the inverter if it vibrates at
high levels, if engine speed changes greatly

or if the engine misres often.

Always disconnect tools or appliances from
the inverter before starting.
