    1 Safety Guidelines WARNING : EXHAUST GAS POISONING  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 bystanders or buildings. WARNING : ELECTRIC SHOCK ...
  • Page 6 CAUTION : FIRE  Do not carry flammable items (such as fuel, gas and paint) or items that are highly combustible near the generator as the muffler, exhaust gas and other parts become extremely hot.  Position this generator 3 ft. (1 m) or more from walls or other hindrances, and on a level surface.
  • Page 7 CAUTION : INJURY  Always be sure to use Lifting Hook when lifting up the generator, and slowly lift it straight up.  Personnel performing lifting work must wear protective gear such as helmets, safety shoes and gloves.  Position the generator on a level stable surface so that it cannot slide or move in any manner.
