Page 6: General Safety
Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, etc. Automatic Standby Generator Owner’s Manual... -
Page 7: Exhaust Hazards
• This is an Automatic Standby Generator, the generator may crank and start at any time when utility is lost. When this occurs, load circuits are transferred to the STANDBY (generator) power source. To prevent injury, before working on this generator (for inspection, service or mainte- nance), always put the generator into the OFF mode and remove the 7.5 Amp fuse from the generator control panel. - Page 8 (NEC 702). Failure to isolate an electrical system by such means will result in damage to the generator and also may result in injury or death to utility power workers due to backfeed of electrical energy.
