    Safety Instructions WARNING : SUFFOCATION FROM EXHAUST FUME Do not operate the generator in poorly ventilated areas such as indoors or tunnels, as the exhaust gas of the engine contains substances that are harmful to human health. Do not direct exhaust fumes at pedestrians or buildings. WARNING : ELECTRIC SHOCK Before connecting or disconnecting the load cables to/from the output terminal, always turn the output circuit breakers to the OFF position, stop the engine, and remove the engine key.
  • Page 6 CAUTION : EYE/SKIN INJURY Wear rubber gloves and other protective wear to protect eyes, skin and clothing from the battery fluid which contains diluted sulfuric acid. If the battery fluid contacts eyes or skin, wash out immediately with a sufficient amount of clean water. Be sure to receive medical treatment, especially if the fluid contacts the eyes.
  • Page 7 CAUTION : PROPERTY DAMAGE If using this generator for medical equipment, check before use with the medical equipment manufacturer, doctor, hospital or similar entity. Check that the generator output setting, output terminal connection and load power source are consistent. Cable burnout can occur due to generated heat if the load current exceeds the allowable current of the cable.
